How to get text from alert box? - javascript

I need to get text from alert box.
<script type="text/javascript">
alert('Some text')
</script>
I don't have enough reputation to upload images..so i upload code instead of image :)
Is there any way to get text "from popup" on Chrome using Greasemonkey?

Query is not clear ..but if I understand it correctly ..there is a JavaScript on a page that results in an alert()
You can get the text of that alert from the JavaScript on the page.
function getAlert() {
// get all scripts
var elem = document.scripts;
// loop and check
for (var i = 0, len = elem.length; i < len; i++) {
var txt = elem[i].textContent.match(/alert\(['"]([^'"]+)['"]\)/);
if (txt) { return txt[1]; } // if matched, return the alert text and stop
}
}
In your case, the above function will return Some text.

Here's another interesting way (if you don't mind overriding the global alert, prompt & cancel functions)...
// Wrap the original window.alert function...
const windowAlert = window.alert;
window.alert = function(message) {
console.log(`window.alert called with message: ${message}`);
return windowAlert(message);
};
alert('FOO');
// Console Output:
// window.alert called with message: FOO
// ========================================================
// Wrap the original window.prompt function...
const windowPrompt = window.prompt;
window.prompt = function(message) {
console.log(`window.prompt called with message: ${message}`);
const input = windowPrompt(message);
console.log(`user entered: ${input}`);
return input;
};
prompt('BAR');
// Console Output:
// window.prompt called with message: BAR
// user entered: xxx
// ========================================================
// Wrap the original window.confirm function...
const windowConfirm = window.confirm;
window.confirm = function(message) {
console.log(`window.confirm called with message: ${message}`);
const choice = windowConfirm(message) ? 'ok' : 'cancel';
console.log(`user clicked: ${choice}`);
return choice;
};
confirm('BAZ');
// Console Output:
// window.confirm called with message: BAZ
// user clicked: ok (or 'cancel' if you click 'cancel')

Get user input from a prompt
var name = prompt('Please enter your name');
if (person!=null)
console.log('The person's name is: ' + name);
Get a yes/no answer
var response = confirm('Press a button');
if (response == true)
console.log("You pressed OK!");
else
console.log("You pressed Cancel!");

Javascript callbacks in asp pages

I've looked at this How-do-i-return-the-response-from-an-asynchronous-call and at why-is-my-variable-unaltered-after-i-modify-it-inside-of-a-function-asynchron , but what I'm trying to do doesn't work.
Since some of our users use IE, it seems that we would have to rely on callbacks.
The background to this question comes from a previous post. Legacy code used VBscript's MsgBox, but now the same functionality must be ported to Javascript.
To provide context, there is a bunch of buttons on a toolbar (hence toolbar.asp) such as "New", "Update", "Delete". The user can navigate to certain parts of the system and for instance create a "New" record for a particular resource/person. The details and functionality are shown on the main part of the screen (hence main.asp).
The system was originally written about 15 years ago (or more).
When the user clicks "Update" on the toolbar.asp, it depends which screen the main.asp was showing. Parts of dovalidation() in main.asp can be swopped (as in a script is fetched from the database) and inserted into dovalidation() depending on what & where the user is.
So some parts are still in Visual Basic 6, but it seems that they are trying to replace the VBscript with Javascript.
So the user is on a specific screen and clicks Update (the toolbar.asp's doupdate() is called).
This doupdate() does a number of checks on the date and other variables and the calls the main.asp's dovalidation().
Depending on where the user finds himself, dovalidation looks different.
In quite a few cases as in the specific example that I am talking about, there used to be a MsgBox in the VBscript code which gave the user a choice depending on the validation done up to that point. However, that VBscript should now be replaced by Javascript. It seems my boss doesn't want to use the normal window.confirm, because she wants to be able to customise the buttons.
VBscript's MsgBox blocked further execution, but now using a jquery confirm doesn't have the same results, because it is non-blocking.
If the validation occurs in such a way that the user is provided with the confirm dialog, and the user clicks on 'Cancel' then the next page should not be shown, but at present, whether the user clicks on 'Cancel' or not, the next page is shown after a couple of seconds.
At the end of the doupdate() function there is:
parentMain.screenform.submit();
Could that be part of why my callbacks don't work?
In a toolbar.asp file, this is called in the doupdate() funtion:
//... Other code that determines variables, fringe scenarios etc.
//...
// Then dovalidation() (in which the blocking MsgBox used to be) is called:
var sErr = parentMain.dovalidation();
if (sErr != ""){
return;
}
//Then the rest of the code which is executed irrespective of the jquery confirm.
//do update
try {
parentMain.document.all("Updating").value = "YES"
parentMain.document.body.scrollTop = 0
parentMain.document.body.scroll = 'no'
parentMain.ShowBusy();
document.getElementById("sysBusy").value = "true";
//parentMain.document.all("clockFrame").style.display = "block";
} catch(e) {
return (e)
}
//do check for resource tag
if (sScreenType.toUpperCase() == "RESOURCE TABLE") {
if (lResource == "0") {
parentMain.document.all("sysresource").value = lDetailResource
}
//alert("looping for resource tag");
var sField = ""
var sCheck = "Resource Tag"
if (!(sScreen == "Resource")) {
/*********************************************************************/
/** loop through the fields and update resouce tag if empty - submit**/
/*********************************************************************/
var elements = parentMain.document.getElementById("screenform").elements;
for (var i = 0, element; element = elements[i++];) {
if ((element.name).indexOf(sCheck) > 0) {
var sValue = element.value
if (sValue.length == 0) {
element.value = lDetailResource
}
}
if ((element.tagName.toUpperCase()) == "SELECT") {
if (element.disabled == true) {
element.disabled = false;
}
}
}
}
}
//submit screen
parentMain.screenform.submit(); //<-- Could this be part of the problem?
}
In the main.asp file the dovalidation function resides. A part of the dovalidation function is swapped out depending on the situation. That is marked between the //################
function dovalidation() {
msErr = "";
//#################
if (msErr.length == 0) {
var vEffectiveDate="";
var vLastRunDate="";
var sStatus="";
var vMsg="";
var sResponse="";
vEffectiveDate = document.getElementById("Smoke.Effective Date").value;
vLastRunDate = document.getElementById("Smoke.Last Run Date").value;
sStatus = document.getElementById("Smoke.Calc Status").value;
vMsg = "";
if ((sStatus).length == 0 ){
sStatus = "SUCCESFUL";
//document.getElementById("Smoke.Calc Status").value= sStatus;
}
if ((vEffectiveDate).length > 0 ){
if (!isDate(vEffectiveDate) ){
vMsg = vMsg+"[Effective Date] Is not a date." + ";\r\n";
} else if ( moment( toDate(vEffectiveDate)).isBefore(toDate(vLastRunDate)) ){
vMsg = vMsg+"[Effective Date] cannot be on/before "+vLastRunDate+"." + ";\r\n";
}
}
if (sStatus.toUpperCase() != "SUCCESFUL") {
$.confirm({
title: "Confirmation",
columnClass: 'col-md-6 col-md-offset-3',
content:"Forecast calculation still busy. Results might not be accurate. Continue?",
buttons: {
confirm: function() {
sResponse= "1";
vMsg = "Response 1";
processMessage(); // <--- added this
},
cancel: function() {
sResponse= "2";
vMsg = "Response 2";
// Moved code here, as it needs to execute when Cancel is clicked
$.alert({
title: "INFORMATION",
columnClass: 'col-md-6 col-md-offset-3',
content: "Screen will refresh. Please click on Update to try again.",
// Code that should execute when alert is closed:
onAction: function () {
document.getElementById("Smoke.Calc Status").value= "REFRESH";
msErr = "ABORT";
processMessage(); // <--- added this
}
});
},
}
});
} else { // <-- added
processMessage();
}
function processMessage() {
// Moved code in a function, as it should only execute after confirm/alert is closed
if (vMsg != "") {
$.alert({
title: 'Validation Message',
columnClass: 'col-md-6 col-md-offset-3',
content: vMsg,
});
msErr = "ERROR";
}
}
}
//#################
return msErr;
}
So I think my problem lies with msErr being returned long before the user has had chance to decide which button on the confirm dialog to choose. If I don't set breakpoints and click on the confirm's cancel then I do see that the alerts are shown, but the page is not refreshed (document.getElementById("Smoke.Calc Status").value= "REFRESH";) and the next page is shown. I think this comes from the sErr == "" in the toolbar.asp file and then the program flow just continues.
Anycase, I tried using callbacks, but the situation hasn't changed.
Here is what I tried to do:
parentMain.dovalidation(function(result){
if (result != ""){
return;
}
});
In main.asp the dovalidation function:
function dovalidation(callback) {
msErr = "";
//#################
if (msErr.length == 0) {
var vEffectiveDate="";
var vLastRunDate="";
var sStatus="";
var vMsg="";
var sResponse="";
vEffectiveDate = document.getElementById("Smoke.Effective Date").value;
vLastRunDate = document.getElementById("Smoke.Last Run Date").value;
sStatus = document.getElementById("Smoke.Calc Status").value;
vMsg = "";
if ((sStatus).length == 0 ){
sStatus = "SUCCESFUL";
document.getElementById("Smoke.Calc Status").value= sStatus;
}
if ((vEffectiveDate).length > 0 ){
if (!isDate(vEffectiveDate) ){
vMsg = vMsg+"[Effective Date] Is not a date." + ";\r\n";
} else if ( moment( toDate(vEffectiveDate)).isBefore(toDate(vLastRunDate)) ){
vMsg = vMsg+"[Effective Date] cannot be on/before "+vLastRunDate+"." + ";\r\n";
}
}
if (sStatus.toUpperCase() != "SUCCESFUL") {
$.confirm({
title: "Confirmation",
columnClass: 'col-md-6 col-md-offset-3',
content:"Forecast calculation still busy. Results might not be accurate. Continue?",
buttons: {
confirm: function() {
sResponse= 1;
vMsg = "Response 1";
processMessage(); // <--- added this
},
cancel: function() {
sResponse= 2;
vMsg = "Response 2";
// Moved code here, as it needs to execute when Cancel is clicked
$.alert({
title: "INFORMATION",
columnClass: 'col-md-6 col-md-offset-3',
content: "Screen will refresh. Please click on Update to try again.",
// Code that should execute when alert is closed:
onAction: function () {
document.getElementById("Smoke.Calc Status").value= "REFRESH";
msErr = "ABORT";
processMessage(); // <--- added this
}
});
},
}
});
} else { // <-- added
processMessage();
}
function processMessage() {
// Moved code in a function, as it should only execute after confirm/alert is closed
if (vMsg != "") {
$.alert({
title: 'Validation Message',
columnClass: 'col-md-6 col-md-offset-3',
content: vMsg,
});
msErr = "ERROR";
}
}
}
//#################
callback(msErr);
}
So, it isn't working as it should, and I don't know what I've done wrong, but I suppose I haven't used the callbacks correctly.
Does it make a difference that it is in two different files?
This has to work given that the parts between the //######### are swopped.
I would appreciate any feedback and guidance.
Well, ok. I started to write a comment, but it is too small for all I need to say, so I will continue in an answer.
I see you added some more code, but... you know, your code are blowing my mind =) what you are trying to do is to get spaghetti-code and make it async.
Throw this away and let's go to the upper level. We call it "program on an interface level".
Example: replace all your big code blocks with functions (with correct name). Like code between //################# will be converted to
function dovalidation(callback) {
msErr = getValidationResult();
callback(msErr);
}
What do I do here is just throw away all your low-level code, because your problem is in the order of execution.
But this is just the first step of converting your code to something other. Next step is realizing that our "virtual" function getValidationResult has some $.confirm and $.alert inside, so it is async. That's why we need to use getValidationResult as async. Two possible ways - convert to Promise or use callbacks. Let's use callbacks. Then our simplified code will convert to:
function dovalidation(callback) {
getValidationResult(callback);
}
That is what I was trying to show on my previous answer.
And now you've added some more code with such a comment: //Then the rest of the code which is executed irrespective of the jquery confirm.. Ok, good, we will name all this code as theRestOfTheCodeIrrespectiveToConfirm(). So your original function call will be converted from this:
//... Other code that determines variables, fringe scenarios etc.
//...
// Then dovalidation() (in which the blocking MsgBox used to be) is called:
var sErr = parentMain.dovalidation();
if (sErr != ""){
return;
}
theRestOfTheCodeIrrespectiveToConfirm();
to this:
//... Other code that determines variables, fringe scenarios etc.
//...
// Then dovalidation() (in which the blocking MsgBox used to be) is called:
parentMain.dovalidation(sErr => {
if (sErr != ""){
return;
}
theRestOfTheCodeIrrespectiveToConfirm(); // <- this will execute only if sErr is empty
});
Am I going to the right direction?
P.S. One thing to ask you - why do you have } in the end of you example code, but no correcsponding {?
Maybe you show us not all code?
There is no need to involve jQuery.
JavaScript has the functions alert, confirm and prompt which are synchronous (i.e. blocking execution until they return) just like MsgBox was.
So if this is easier to you, you can keep your original code structure this way. Because as it was explained in the "how do I return a response from an asynchronous call" article, you cannot make the dovalidation function return anything that depends on the result of an asynchronous operation like the $.confirm that you currently use, since that would require time travel ;) - but you can make it dependent on synchronous operations like JS' built-in confirm.
You are mixing sync code with async... Because $.confirm is async, but you call dovalidation as sync.
Note: your code is very strange, maybe because of small JS experience, so I will try to guess what you need. You can ask if something in my code is incorrect.
Your second example with callback is more close to working solution, but you need to call the callback only if you know the user's answer.
So let's change your code a bit. Extract processMessage function (now it is async) and call processMessage with correct parameters:
function processMessage(vMsg, msErr, callback) {
// Moved code in a function, as it should only execute after confirm/alert is closed
if (vMsg) {
$.alert({
title: 'Validation Message',
columnClass: 'col-md-6 col-md-offset-3',
content: vMsg,
});
msErr = "ERROR";
}
callback(msErr); // <-- return result
}
function dovalidation(callback) {
var vMsg = "", msErr = "";
//#################
if (msErr.length == 0) {
var vEffectiveDate = "";
var vLastRunDate = "";
var sStatus = "";
var sResponse = "";
vEffectiveDate = document.getElementById("Smoke.Effective Date").value;
vLastRunDate = document.getElementById("Smoke.Last Run Date").value;
sStatus = document.getElementById("Smoke.Calc Status").value;
vMsg = "";
if ((sStatus).length == 0) {
sStatus = "SUCCESFUL";
document.getElementById("Smoke.Calc Status").value = sStatus;
}
if ((vEffectiveDate).length > 0) {
if (!isDate(vEffectiveDate)) {
vMsg = vMsg + "[Effective Date] Is not a date." + ";\r\n";
} else if (moment(toDate(vEffectiveDate)).isBefore(toDate(vLastRunDate))) {
vMsg = vMsg + "[Effective Date] cannot be on/before " + vLastRunDate + "." + ";\r\n";
}
}
if (sStatus.toUpperCase() != "SUCCESFUL") {
$.confirm({
title: "Confirmation",
columnClass: 'col-md-6 col-md-offset-3',
content: "Forecast calculation still busy. Results might not be accurate. Continue?",
buttons: {
confirm: function() {
sResponse = 1;
vMsg = "Response 1";
processMessage(vMsg, msErr, callback); // <--- added this
},
cancel: function() {
sResponse = 2;
vMsg = "Response 2";
// Moved code here, as it needs to execute when Cancel is clicked
$.alert({
title: "INFORMATION",
columnClass: 'col-md-6 col-md-offset-3',
content: "Screen will refresh. Please click on Update to try again.",
// Code that should execute when alert is closed:
onAction: function() {
document.getElementById("Smoke.Calc Status").value = "REFRESH";
msErr = "ABORT";
processMessage(vMsg, msErr, callback); // <--- added this
}
});
},
}
});
} else { // <-- added
processMessage(vMsg, msErr, callback); // <--- added this
}
}
//#################
}
Note: this code is not "clean". If this function dovalidation you showed us has full code, then you can clean the code. This code is runnable (better use it in fullscreen), but I still do not understand what you are trying to do...

How to add the value from an input box to an array and then output its contents?

How can I go about adding the value of an input box into an array and then display the contents of that array?
This is what I've come up with and I'm not sure why it's not working - the console.log doesn't post anything to the console, either.
var user = user;
if (!user) {
user = prompt('Please choose a username:');
if (!user) {
alert('Your name has been set to "Anonymous"');
} else {
alert('Your name has been set to "'+ user +'"');
}
}
var items = [];
function userArray() {
items.push(user);
return false;
console.log(items);
}
socket.on('onlineUsers', function (data) {
$('.dispUser').html(items);
});
The rest of the code in the file is below, just in case it helps... (changed the return statement, as per the first answer)
var user = user;
if (!user) {
user = prompt('Please choose a username:');
if (!user) {
alert('Your name has been set to "Anonymous"');
} else {
alert('Your name has been set to "'+ user +'"');
}
}
var items = [];
function userArray() {
items.push(users);
console.log(items);
return false;
}
socket.on('onlineUsers', function (data) {
$('.dispUser').html(items);
});
//Counts the number of users online
socket.on('count', function (data) {
$('.user-count').html(data);
});
//Receives messages and outputs it to the chat section
socket.on('message', function (data) {
$('.chat').append('<p><strong>' + data.user + '</strong>: ' + data.message + '</p>');
$('.chat').scrollTop($('.chat').height());
});
//SENDING OF THE MESSAGE
//Submit the form through HTTPS
$('form').submit(function (e) {
e.preventDefault();
// Retrieve the message from the user
var message = $(e.target).find('input').val();
// Send the message to the server
socket.emit('message', {
user: user || 'Anonymous',
message: message
});
// Clears the message box after the message has been sent
e.target.reset();
$(e.target).find('input').focus();
});
Answer
Your implementation is fine, but you have a bug which is preventing it from working as you've described.
The call to console.log(items) does not print anything, because that line of code never runs.
When you return from a function, the subsequent lines of code will not be ran. You should return as the last line within your function, or wrap it in a conditional.
For example:
function userArray() {
items.push(user);
console.log(items);
return false;
}
How to debug
Learning the techniques to figure this issue out yourself is an invaluable tool. You can leverage a debugger, such as the Chrome Devtools, to add breakpoints to your code. These will allow you to stop execution on a particular line, view the value of variables, and step through the remaining lines of code.
Doing so would make it clearly visible that the line of code is never running.

How to return false from a main function after an ajax callback?

I perform an edit to ensure against duplicate emails by making an ajax call and supplying a callback. If a duplicate exists, I want to return false from submit event. Is there an elegant way to achieve this without setting async=false? What I tried (see emailCallback) is not working.
submit event
EDIT (included the rest of the submit handler).
$("#form-accounts").on("submit", function (e) {
e.preventDefault();
if (!$(this).get(0).checkValidity()) return false;
if (!customValidation(true, false)) return;
checkDupEmail(emailCallback);
function emailCallback(result) {
if (result) return (function () { return false } ());
}
if ($("#submit").text() == "Create Account") {
var formData = $("#form-accounts").serialize().replace("''", "'");
ajax('post', 'php/accounts.php', formData + "&action=create-account", createSuccess);
function createSuccess(result) {
if (isNaN(result)) {
showMessage(0, result);
return;
}
localStorage.setItem("account-id", result);
debugger
setUsertype($("input[name=user-type]:checked").val());
showMessage(1, "Account Created");
};
return
}
var rString = randomString(32, '0123456789abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ');
function randomString(length, chars) {
var result = '';
for (var i = length; i > 0; --i) result += chars[Math.floor(Math.random() * chars.length)];
return result;
};
var anRandom = randomString(14, rString);
$("#code").val(anRandom);
console.log("v-code=" + anRandom);
$("#submit").css({ 'display': 'none' });
$("#verify").css({ 'display': 'block' });
var subject = "Writer's Tryst Verification Code"
$("#subject").val(subject);
var msg = "This mail is intended for the person who requested verification of email ownership at Writers-Tryst (" + getWriterTrystURL() + ").\n\n" + "Double click on the code below and then copy it. Return to our website and and paste the code.\n\nYour verification code: \n\n" + anRandom;
$("#msg").val(msg);
var formData = $("#form-accounts").serialize().replace("''", "'");
ajax('post', 'php/sendmail.php', formData, successMail, "create-account error: ");
function successMail(result) {
$("#ver-email-msg").val("An email has been sent to you. Double-click the verification code then copy and paste it below.").css({ 'display': 'block' });
}
});
function checkDupEmail(callback) {
var data = {};
data.action = "validate-email";
data.email = $("#email").val();
ajax('post', 'php/accounts.php', data, emailSuccess);
function emailSuccess(result) {
if (parseInt(result) > 0) {
showMessage(0, "The email address is in use. Please supply another or login instead of creating a new account.")
callback(true);
} else callback(false);
}
}
Instead of passing a callback, why don't you just submit the form when your Ajax call completes successfully?
$("#form-accounts").on("submit", function (e) {
// Always cancel the submit initially so the form is not submitted until after the Ajax call is complete
e.preventDefault();
...
checkDupEmail(this);
...
});
function checkDupEmail(form) {
var data = {};
data.action = "validate-email";
data.email = $("#email").val();
ajax('post', 'php/accounts.php', data, function(result) {
if (parseInt(result) > 0) {
showMessage(0, "The email address is in use. Please supply another or login instead of creating a new account.")
} else {
form.submit();
}
}
}
A better approach than that would be to submit your form using Ajax. That would eliminate the need for two calls to the server.

Javascript function "does not exist". Bad syntax but can't see it

The javascript is supposed to handle form submission. However, even if called with
script src="js/registerform.js"> Uncaught ReferenceError: sendreg is not defined .
The function is called onclick. Can be reproduced on www.r4ge.ro while trying to register as well as live edited. Tried jshint.com but no clue.
I will edit with any snips required.
function sendreg() {
var nameie = $("#fname").val();
var passwordie = $("#fpass").val();
var emailie = $("#fmail").val();
if (nameie == '' || passwordie == '' || emailie == '') {
alert("Please fill all the forms before submitting!");

I'm guessing here but... I imagine you are doing something like
...<button onclick="sendreg">...
And you have your <script> in the bottom on the code. Just put them on top or use $("#mybtn").click(sendreg)
Try using $("#mybtn").click(sendreg) instead of inline onclick.
The script wasn't called in the html. sorry for wasting time. A simple
<script src="js/registerform.js"></script> Fixed it.
There is no syntax error there, and I don't see any such error when trying the page.
The error that you get is that you can't make a cross domain call. Do the request to the same domain:
$.post("http://www.r4ge.ro/php/register.php", {
or:
$.post("/php/register.php", {

$("#submit").click not working :/

I've tried everything I can think of to get this "send" button to work, but I'm not very good at javascript :(

Prehaps someone here can tell me where i'm going wrong?
Many thanks

You are binding the submit before the element exists, move the code after the form or put it inside $(document).ready:
jQuery(document).ready(function () {
jQuery("#submit").click(function () {
console.log("button clicked");
// declare these vars
var name = jQuery("#name");
var email = jQuery("#email");
var message = jQuery("#message");
var human = jQuery("#human");
var success = jQuery("#success");
var error = jQuery("#error");
// reset these vars
success.html("");
error.html("");
// ajax call to script.php
jQuery.getJSON("mailer.php", {
name: name.val(),
email: email.val(),
message: message.val(),
human: human.val()
}, function (html) {
// if html from script.php == 1, happy days
if (html == '1') {
jQuery("#contact").hide()
success.html("Thank You, your message has been sent.")
error.show()
}
else {
error.html(html)
}
});
});
});
