I have two scripts, first of them clicks on the button and after that browser opens a new window, where i should click on the other button by the second script, is it possible to run them both at the same time, I mean like unite those scripts together?
function run() {
var confirmBtn = document.querySelector(".selector,anotherSelector ");
}
after this new window appears and here`s the second part of my script
var rooms = document.querySelectorAll(" .btn-a-offers");
console.log(rooms);
for (var room = 0; room < rooms.length; room++) {
rooms[room].click();
}
var prices = document.querySelectorAll(" .li-right-side>strong");
console.log(prices);
for (var price = 0; price < price.length; price++) {
}
var prices = [];
document.querySelectorAll(".new-pa-hotelsoffers .li-right-side > strong").forEach(function(price) {
prices.push(parseFloat(price.innerHTML.replace(/[^0-9.]/g, "")))
})
console.log(
Math.min(...prices).toFixed(2)
)
My English is not that good so I want to be sure that I explained everything right, second script must be executed in the new window, that opens after first script
Depending on the logical dependancy of your application and the use of the functions, you could execute the second function in a document.ready function on the second page.
Example:
<script>
//jQuery
$( document ).ready(function() {
secondFunction();
});
//Pure JS
function r(f){/in/.test(document.readyState)?setTimeout('r('+f+')',9):f()}
r(function() {
secondFunction();
});
</script>
However, if the page is to act independantly, and the second function is only to respond upon the execution of the first function, then that solution would not be the one you are looking for.
In the case where the function has to act entirely dependant on the use of the first function you could parse a value in the URL (better known as a GET variable) and check if that value is set.
Example:
<script>
functionOne() {
window.location.href = '/your_page.php?click=1';
}
</script>
Then on your second page you need to retrieve the GET variable.
<?php
$clicked = $_GET['click'];
?>
You can then perform a check to see if the variable has been set and fire your function upon that logic.
<?php
if($clicked != "") {
echo '
<script>
functionTwo();
</script>';
}
?>
Another way of doing it could be by the use of AJAX and have the other function execute in the AJAX' success function. That way you can eliminate the use of the GET variable, which is visible in the URL.
Example:
<script>
functionOne() {
$.ajax({
type : "POST", //or GET
url : "/your_page.php",
data : {
//parse your POST variable data if any
// variable : value,
// anotherVairable : anotherValue
// [....]
},
success: function (html) {
//Success handling
secondFunction();
}
})
}
</script>
Note that the AJAX used in the example is jQuery AJAX, so if you want to use some AJAX logic involving this structure, you'll need to include a jQuery library.
You should pass some parameter in the URL query like this:
// first-script.js
openNewWindow('http://example.com?run-second-script=1') // openNewWindow is fake function, just for demo
// second-script.js
if (window.location.search.includes('run-second-script=1')) { ... your code here ...}

I'm making a chat with the simple javascript:
<script>
function chatClick(messages_other_user) {
$('#chatBox').remove();
document.body.innerHTML += "<div id='chatBox' class='chatDiv'></div>";
$("#chatBox").load("subs/chat/chat.php?ou="+messages_other_user);
}
</script>
This function is called in several links with the variable "messages_other_user" changing.
In the file "chat.php" I get the variable of "ou" and I have a script that writes to the console:
if (isset($_GET['ou'])) { $otherUserChat = $_GET['ou']; } else $otherUserChat = 0; // get $otherUserChat
<script>
$(document).ready(function() {
var chatUpdateVar = setInterval(function() {
console.log("<?= $otherUserChat ?>");
}, 2000);
$.ajaxSetup({ cache: false });
});
</script>
But the .remove line doesn't quite get rid of the javascript in the chat.php file. When I click a link to call the javascript chatClick function, it works fine. But when I then click another link that calls chatClick with a different variable for "messages_other_user" the old one keeps firing along with the new one.
How can I destroy the old javascript completely so it doesn't run anymore?
I found the solution - and I was mistaken by the true culprit of the issue.
I thought a console.log would yield the same result as what I truly do - I just chose to replace with console.log in the code for simplicity. So I guess I've learned that's a stupid thing to do.
What is actually happening in the chat.php file in the document ready script is this:
$(document).ready(function() {
var chatUpdateVar = setInterval(function() {
$("#chatArea").load("subs/chat/chatContent.php?ou="+<?= $otherUserChat ?>);
console.log("updated");
}, 4000);
});
I figured out I didn't readlly need to use the document ready, so I instead, I just do this directly in my script:
var chatUpdateVar = setInterval(function() {
$("#chatArea").load("subs/chat/chatContent.php?ou="+<?= $otherUserChat ?>);
console.log("updated");
}, 4000); // CHECK FOR UNREAD: 1000 equals 1 second
$.ajaxSetup({ cache: false });
For closing the chat window, I now trigger this function:
function closeChat() {
clearInterval(chatUpdateVar);
$('#chatBox').remove();
}
And in the file that calls the above script (chat.php), I check if the function closeChat exists - and if it does, I run it. This is part of the cal to the chat.php:
function chatClick(messages_other_user) {
if (typeof closeChat === "function") {
closeChat();
}
document.body.innerHTML += "<div id='chatBox' class='chatDiv'></div>";
$("#chatBox").load("subs/chat/chat.php?ou="+messages_other_user);
}
I have a page displaying data from a json feed and I also have a button which loads more of the feed on click of a button. My aim is to append some content inside the page for each feed item. I have been able to create a function which does this on load of the page, but I am unsure how to make this work with the aysynchronous loading of more data.
I understand I need to use the .done() callback to make this work but need some guidance how to implement it correctly.
This function appends the new content initially:
function appendFeed() {
$('.feed__item').each(function (index) {
$feedItem = $('.feed__item', $(this));
$feedItem.append('<div class="feed-gallery"></div>');
for (var i = 1; i <= 5; i++) {
var $count = i;
if ($count > 1) {
$('.feed.gallery', $(this)).append('<div><img data-lazy="//placehold.it/50x50"></div>');
};
});
}
This is where the .done() callback is referred, on click of a button:
$('button').click(function(){
$.getJSON(uri, function (json, textStatus) {
// do stuff
}).done(function (json) {
// do stuff - in my case this would be appendFeed()
});
});
I have already called the appendFeed() function, but if I put it inside the .done() callback on click the button, then it appends the feed again. How do i prevent the duplication for the feed that is already on the page?
This is how you will write.
<script type="text/javascript">
$.getJSON("/waqar/file.php").done(function (data) {
$(".output").append(data);
});
</script>
in the jquery.get() function, the first parameter is URL, is that the url to the content I want to retrieve or to the Controller/action method.
The problem is I'm building an asp.net-mvc application and I'm not sure what to pass as this parameter. Right now I'm passing my partialview.cshtml but nothing is being returned, not sure if I'm doing this right or wrong.
Here's what I got
<div id="editor_box"></div>
<button id="add_button">add</button>
<script>
var inputHtml = null;
var appendInput = function () {
$("#add_button").click(function() {
if (!inputHtml) {
$.get('AddItem.cshtml', function (data) {
inputHtml = data;
$('#editor_box').append(inputHtml);
});
} else {
$('#editor_box').append(inputHtml);
}
})
};
</script>
also, what is the second parameter "function (data)" is this the action method?
You need to remove var appendInput = function () { from the script. You are defining a function but never calling it. Just use the following (update you action and controller) names
<script>
var inputHtml = null;
$("#add_button").click(function() {
if (!inputHtml) {
$.get('#Url.Action("SomeAction", "SomeController")'', function (data) {
inputHtml = data;
$('#editor_box').append(inputHtml);
});
} else {
$('#editor_box').append(inputHtml);
}
});
</script>
Edit
Based on your script you appear to be requiring the content only once (you then cache it and add it again on subsequent clicks. Another alternative would be to render the contents initially inside a hidden <div> element, then in the script clone the contents of the <div> and append it to the DOM
<div id="add style="display:none">#Html.Partial("AddItem")</div>
$("#add_button").click(function() {
$('#editor_box').append($('add').clone());
});
The first argument to $.get is the URL which will respond with the expected data. jQuery/JavaScript don't care what kind of server side architecture you have or the scripting language. Whether the URL looks like a file AddItem.cshtml or a friendly route like /User/Sandeep, it doesn't matter as far as the client side is concerned.
In the case of ASP.NET, your URL endpoint can be generated like so:
$.get('#Url.Action("SomeAction", "SomeController")', function (data) {
I'm trying to select a row from a json array using jquery. This is what i have:
$(document).ready(function() {
$.getJSON( "js/collectie.json", function(data) {
jsoncollectie = data;
})
$( "#collectie li" ).click(function(){
var thumb_id = $(this).data("id");
for(var i = 0; i < jsoncollectie.stoelen.length; i++){
if(jsoncollectie.stoelen[i].ref == thumb_id){
$("#detailimage").attr('src', jsoncollectie.stoelen[i].image);
$("#detailimage").attr('title', jsoncollectie.stoelen[i].title);
$("#title").html('<h4> '+jsoncollectie.stoelen[i].naam+' </h4>');
$("#secondaryimage").attr('src', jsoncollectie.stoelen[i].secondaryimage);
$("#secondaryimage").attr('title', jsoncollectie.stoelen[i].secondarytitle);
$("#description").html('<p> '+jsoncollectie.stoelen[i].description+' </p>');
}
}
});
});
Now when i click on a list item (#collectie li) the console outputs "ReferenceError: jsoncollectie is not defined". I don't know why it's doing that and i'm pretty sure it worked two weeks ago. Don't know much about javascript/jquery yet, but i'm slowly learning.
$(document).ready(function()
{
// Provide access to data outside of the getJSON call
var m_oJsonCollectie = null;
// Get the data
$.getJSON( "js/collectie.json", function(data)
{
// Set the data
m_oJsonCollectie = data;
// Apply the click handler
$( "#collectie li" ).click(function()
{
var thumb_id = $(this).data("id");
for(var i = 0; i < m_oJsonCollectie.stoelen.length; i += 1)
{
if(m_oJsonCollectie.stoelen[i].ref == thumb_id)
{
$("#detailimage") .attr('src', m_oJsonCollectie.stoelen[i].image);
$("#detailimage") .attr('title', m_oJsonCollectie.stoelen[i].title);
$("#title") .html('<h4> '+ m_oJsonCollectie.stoelen[i].naam+' </h4>');
$("#secondaryimage").attr('src', m_oJsonCollectie.stoelen[i].secondaryimage);
$("#secondaryimage").attr('title', m_oJsonCollectie.stoelen[i].secondarytitle);
$("#description") .html('<p> '+ m_oJsonCollectie.stoelen[i].description+' </p>');
}
}
});
});
});
JS have block level scope, so you wont get the values outside of the function unless you provide access to them or they are declared in global scope (which is considered bad practice).
This pattern should help you keep your data accessible, and only applies the click handler if the getJSON call is successful.
Check that your getJSON request is being received and returned by using deferred methods
// Syntax that will shed light to your issue :
$.getJSON
(
"js/collectie.json",
function (oJSON) { /*success*/ }
)
.done(function() { /* succeeded */ })
.fail(function() { /* failed */ })
.always(function() { /* ended */ });
I came to this conclusion due to comments and the fact that a variable only declared in the success handler for getJSON was undefined. Since the JSON containing variable was undefined, the success handler must never have been called. Chances are that the path to the JSON you are trying to get is incorrect.
Documentation for the methods to accomplish :
getJSON
done
fail
always
UPDATE
Knowing that the response is 304, and the results are undefined are the important details here. This issue has been addressed by jQuery already here
This is actually correct, given the ifModified header has not been set to false.
To fix this issue, use ajaxSetup() to modify the header.
NOTE : the use of this method is not recommended by jQuery, but in this case it works.
// place this is document ready handler before making any calls.
$.ajaxSetup({ ifModified : false });
Is there anyway to reload just the AJAX request, so that it updates the content pulled from the external site in the code below?
$(document).ready(function () {
var mySearch = $('input#id_search').quicksearch('#content table', { clearSearch: '#clearsearch', });
var container = $('#content');
function doAjax(url) {
if (url.match('^http')) {
$.getJSON("http://query.yahooapis.com/v1/public/yql?"+
"q=select%20*%20from%20html%20where%20url%3D%22"+
encodeURIComponent(url)+
"%22&format=xml'&callback=?",
function (data) {
if (data.results[0]) {
var fullResponse = $(filterData(data.results[0])),
justTable = fullResponse.find("table");
container.append(justTable);
mySearch.cache();
$('.loading').fadeOut();
} else {
var errormsg = '<p>Error: could not load the page.</p>';
container.html(errormsg);
}
});
} else {
$('#content').load(url);
}
}
function filterData(data) {
data = data.replace(/<?\/body[^>]*>/g, '');
data = data.replace(/[\r|\n]+/g, '');
data = data.replace(/<--[\S\s]*?-->/g, '');
data = data.replace(/<noscript[^>]*>[\S\s]*?<\/noscript>/g, '');
data = data.replace(/<script[^>]*>[\S\s]*?<\/script>/g, '');
data = data.replace(/<script.*\/>/, '');
data = data.replace(/<img[^>]*>/g, '');
return data;
}
doAjax('link');
});
Right now I have a button which reloads the entire page, but I just want to reload the AJAX request. Is this even possible?
Edit: I need to specify more. While it can easily call the AJAX again, can it also replace the info that is already there?
You just need to call the doAjax function again on button click...
$("#buttonID").on("click", function() {
doAjax("link");
});
Add that into the above document.ready code and set the button ID correspondingly.
Then change
container.append(justTable);
to
container.html(justTable);
In your doAjax function you append HTML onto an element. If you overwrite the element's HTML instead of appending to it then the HTML will be "refreshed" each time the doAjax function runs:
Simply change:
container.append(justTable);
To:
container.html(justTable);
And of-course you can bind a click event handler to a link (or any element) like the rest of the answers show. Make sure you bind the click event in the proper scope (inside the document.ready event handler) so the doAjax function will be accessible from the click event handler.
