When doing a login, is there a message that pops up in the form itself
instead of alert popup message? Instead of popup screen, I want it to just show a message, login success, and disappear and then redirect.
alert("Login successful.")
Natively there is not.
You're thinking of a modal. Check out a jquery UI modal dialog example at https://jqueryui.com/dialog/#modal-message
This is a simple example of a custom messagebox. You can design it however you like
https://jsfiddle.net/mba25ma8/1/
html:
<div id="messageBox">Loggin successfull</div>
<input type="text" placeholder="Login name">
<button>Login</button>
css:
#messageBox {
display:none;
background-color: blue;
border: 1px solid #abc;
color: white;
position: fixed;
padding: 20px;
top:0;
left: 50%;
height: 50px;
}
jQuery:
$(function(){
$("button")
.on("click", function(){
$("#messageBox")
.slideDown("fast",function(){
$(this).delay(2000).slideUp("fast");
});
// redirect to new page here
});
});

I have a web page that contains a button. When the button is clicked it calls some code in my code behind that processes. I want to display a "processing" message and a modal to make it so the user has to wait for the processing to be done before they do anything else. I use a javascript function to show the "processing" message and the modal when the button is clicked. When the processing is done the message goes away but the modal stays.
Here's my code:
<script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js"></script>
<script language="javascript" type="text/javascript">
function ShowProgress2() {
setTimeout(function () {
var modal = $('<div />');
modal.addClass("modal2");
$('body').append(modal);
var loading2 = $(".loading2");
loading2.show();
var top = Math.max($(window).height() / 2 - loading2[0].offsetHeight / 2, 0);
var left = Math.max($(window).width() / 2 - loading2[0].offsetWidth / 2, 0);
loading2.css({ top: top, left: left });
}, 200);
//$('modal2').modal('hide'); //this does not hide the modal when processing is done
//document.getElementById('modal2').style.display = 'none'; //this does not hide the modal when processing is done
}
</script>
.modal2
{
position: fixed;
top: 0;
left: 0;
background-color: black;
z-index: 99;
opacity: 0.8;
filter: alpha(opacity=80);
-moz-opacity: 0.8;
min-height: 100%;
width: 100%;
}
.loading2
{
font-family: Arial;
font-size: 10pt;
border: 5px solid #67CFF5;
width: 200px;
height: 100px;
display: none;
position: fixed;
background-color: White;
z-index: 999;
}
<asp:Button runat="server" ID="MedicaidDataGenerateBillingFile_Generate" Text="Generate" width="100px" OnClientClick="ShowProgress2();"/>
<div class="loading2" align="center" style="display:none;">
<div style="margin: auto; text-align: center; position: absolute; top: 0px; left: 0px; z-index: 9998; width: 100%; height: 100%; background-color: #fff; filter: alpha(opacity=70); opacity: 0.7;">
<asp:Image ID="Image1" runat="server" ImageUrl="~/Images/activity/roller.gif" /><br />
Generating Billing File...
</div>
</div>
Running this as is when the button is clicked the modal displays and the processing message displays in the middle of the modal. When the processing is finished the processing message goes away but the modal stays visible. I've tried a couple of things that are listed at the end of the javascript function that I have commented out, neither of them work to hide the modal. I need the code to make it so the modal goes away/is hidden at the same time the processing message goes away. If anyone would help me out with what needs to be changed/added to my code to accomplish this I would be grateful, thanks in advance.
You define modal like this:
var modal = $('<div />');
modal.addClass("modal2");
$('body').append(modal);
document.getElementById('modal2').style.display = 'none';
this doesnt work, bc you modal doesn't have any id property, when you created it, only class. Either assign it, or use the class
$('modal2').modal('hide');
It doesn't work, because the class in jQuery should be written with dot $('.modal2');
And if you are not using any plugins for modals, the code should be
$('.modal2').hide();
After doing some additional looking into this I found a solution to getting the modal to hide/go away. I found this bit of code in another page where the similar code is being used and the modal is hidden after the processing is done:
<Triggers>
<asp:PostBackTrigger ControlID ="MedicaidDataGenerateBillingFile_Generate" />
</Triggers>
I included this code in my code and set the ControlID equal to my button ID that is getting clicked and now when the processing is finished the processing message goes away and so does the modal.
I hope this can help someone else.
I have an <input> field inside a div that is giving me trouble.
It is inside a div with position absolute. When I click on it, it does not get the focus, so I cannot type inside it.
The other parts of an input field work as they should: The cursor changes to the text symbol when over it, I can focus on it using the right-click with the mouse or the Tab key and when it DOES get focus I can type on it normally.
I even binded a console log to it when clicked, just to make sure the the correct element being clicked. The log does happen, but it still doesn't get the focus on clicking.
Does anyone have an idea of what may be happening here?
Edit: added more parts of my code, sorry for having such little code before.
Here is my code:
// link that makes the form appear, on another part of the UI
jQuery("#link").on("click", function() {
jQuery(".form").show()
})
jQuery("#close-button").on("click", function() {
jQuery(".form").hide()
})
// This was added to test if the click was happening,
// it does not work with or without this
jQuery("#input-field").on("click", function(e) {
console.log("clicked")
console.log(e.target) // this is returning the "input-field" element
})
.form {
background-color: #EAE8E8;
position: absolute;
width: 99%;
right: 0;
z-index: 100;
bottom: 0;
display: none;
border: 1px solid;
}
#close-button {
float: right;
cursor: pointer;
}
/* input-field doesn't have any CSS defined by code yet */
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<button id="link">Click to show form</button>
<div class="form">
<!-- this has position: absolute -->
<img src="'/close.png" id="close-button">
<!-- Here are some other images that can be clicked... that all works fine -->
<input id="input-field" />
<!-- this is not getting focused when clicked -->
</div>
You might add .focus() to autofocus your desired input. Here is your example:
jQuery("#link").on("click", function() {
jQuery(".form").show()
// Add to auto focus your input
jQuery("#input-field").focus();
})
jQuery("#close-button").on("click", function() {
jQuery(".form").hide()
})
.form {
background-color: #EAE8E8;
position: absolute;
width: 99%;
right: 0;
z-index: 100;
bottom: 0;
display: none;
border: 1px solid;
}
#close-button {
float: right;
cursor: pointer;
}
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<button id="link">Click to show form</button>
<div class="form">
<img src="'/close.png" id="close-button">
<input id="input-field" />
</div>
I've created an expanding search bar: You click on the magnifying glass the input extends out and to the right, click it again and it closes. (See Fiddle Below).
I'm new to the world of JS and I thought this would be a great opportunity to implement some logic. Here's what I;m trying to do:
If the search bar is open and the inner.html is empty, if you click the "search" magnifying glass, I want to prevent the default submission of the form and simply close the search bar
If there is text, I want the form to be submitted.
Right now I've got the elements layered in such a way as to when you click the "search" button for the first time, the bar extends and the z-index of the button drops to one where the actual submit button is higher, but I want to control the functionality a little more.
What I've tried:
I tried creating a function that added an event listener that said, basically, if the bar has a width of 700px (the extended length) and the inner html is empty, bring the z-index of the extend button up back higher than the submit simply close the form. But I can't seem to work the logic out properly.
I'm wondering how in JS you can control the z-index.
Here is the code I tried and did not work. I tried something simply like just alerting when the task I wanted to watch for was done first but it doesn't seem to be working.
Any help would be wonderful.

HERE IS THE FIDDLE: https://jsfiddle.net/theodore_steiner/7begmkf3/37/
Your issue can be solved using a few basic JavaScript elements (if you're looking to get into basic logic, these are important to know). The JS uses onsubmit, onclick, and some basic form logic. Basically, when you try to submit the form it checks if the form is empty, and if it is, the program refuses to submit the code. I added the new JavaScript to the HTML file:
<script>
function check(){
value = document.forms["myForm"]["search"].value;
if(value == "" || value == null){
alert("please enter a search term");
return false;
}else{
document.getElementById("myForm").submit();
}
}
</script>
<div id="wrap">
<form id="myForm" onsubmit="return check()">
<input id="searchBar" name="search" type="text" placeholder="What are we looking for?" />
<input id="search_submit" value="" type = "submit">
</form>
</div>
fiddle: https://jsfiddle.net/q1L3Lstx/1/
It might also help in the future to look at the required element: http://www.w3schools.com/tags/att_input_required.asp
I saw a couple of issues with the code.
search and search_submit are pointing to the wrong items they can be like this:
var search = document.getElementById("search");
var search_submit = document.getElementById("search_submit");
You could call a function on submit. like this:
<form id="myForm" onsubmit="myFunction(event)">
finally you can work your code inside that function:
function myFunction(e){
if(search.value.length <= 0){
e.preventDefault();
alert('empty');
}
}
So I'm making a sort of blog posting system or TODO list, however you want to call it.
I want that the following can happen / is possible:
[Working] The user types something in the textarea
[Working] The user clicks on the button.
[Working] A new div will be created with the text of the textarea.
[Working] The textarea will be empty.
[Not Working] The user has got the choice to delete the post by clicking the 'X' on the right side of each '.post' div.
BUT: If I click on the button when there's nothing in the textarea, there appears an empty div, with only an 'X' close button, no background color either. They appear on the same line as the previous message, so you can get a lot of 'X's next to each other.
AND: Clicking the 'X' close button doesn't do anything. No errors in Firefox console.
If it's not clear enough, run this JSFiddle, click the button and I think you'll understand what I mean:

You appear to have two issues:
1) You don't want a post to be created if the textarea is empty
Simple fix . . . check to see if it is empty, before calling the logic to add the new post (and use jQuery's $.trim() to account for only blank spaces):
$('#button').click(function() {
var text = $.trim($('#poster').val());
if (text !== "") {
$('#posts').prepend("<div class='post'>" + text + "<span class='close-post'>×</span></div>");
$('#poster').val('');
}
});
2) The 'X' buttons are not closing the posts
This also should be a pretty easy fix . . . the reason that they are not working is because the 'X' buttons don't exist when the page is loaded so $('.close-post').click(function() { is not binding to them on page load. You will need to delegate that event binding, so that it will apply to the 'X' buttons that are dynamically added after the page is loaded.
Now, not knowing what version of jQuery that you are using (I can't access jsFiddle from work), I'll point you to the right place to figure out the correct way to do it: https://api.jquery.com/on/
If it is jQuery 1.7 or higher, you would do it like this:
$("#posts").on("click", ".close-post", function() {
$(this).parent().hide();
});
If your version is earlier than that, then investigate the jQuery .delegate() and .live() methods to determine which is the right one to use for your code..
Try this:
$(document).ready(function() {
$('#button').click(function(event) {
event.preventDefault();
var text= $('#poster').val();
if (text === '') {
alert('Nothing to post!');
return;
}
$('#posts').prepend("<div class='post'>" + text + "<span class='close-post'>×</span></div>");
$('#poster').val('');
});
$('#posts').on('click', '.close-post', function() {
$(this).closest('.post').fadeOut();
});
});
JSFiddle
The way you are doing this, the user will only ever see what they are posting - if you're trying for a chat type where users talk to each other then you will need to store what is being typed on the server side and refresh the screen using something like ajax
but in response to your question, you need to bind the close click like this:
$( "#posts" ).on( "click", ".close-post", function() {
$(this).parent().hide(); // $(this) is the clicked icon, the way you did it above wouldn't as if it had the dollar, it would close all .close-post parents
});
See the part about delegated events: http://api.jquery.com/on/
I'm trying to understand why the message generated by jquery it's changing position everytime a field gets empty!
So, if the message is generated by the feedback of ajax it's placed in the proper place which is right beneath the login box. If the field (input box) is empty on submit the ajax script is not called and the message of empty field it's shows right on but 40px or more beneath.
The jquery script:
<script type="text/javascript">
<!--
$(document).ready(function(){
$("#loginform").submit(function(){
$('#loginform input[type=text]').each(function(n,element){
if ($(element).val()=='') {
$(".message").html('<p>O campo '+element.id+' tem de ter um valor!</p>').fadeIn("slow").delay(2000).fadeOut(1000);
return false;
}
else{
$.post("login.php", { usrname:$("#Nome").val(), passwd:$("#Palavra-passe").val()}, function(data){
if(data == '1'){
$("#subLog").hide();
$(".message").html('<p>Login efectuado com sucesso, a redirecionar...</p>').fadeIn("slow").delay(2000).fadeOut(1000, function (){
$("#login").fadeOut('slow', function(){
location.reload();
});
});
}
else{
$("#subLog").hide();
$(".message").html('<p>Erro! Tente novamente por-favor!</p>').fadeIn("slow").delay(1500).fadeOut(1000, function(){
$("#subLog").fadeIn('fast');
});
}
});
}
});
return false;
});
});
//-->
</script>
The css message style:
.message{
text-align:center;
color: white;
background: rgba(0, 0, 0, .5);
margin-top: 65px;
padding: 4px;
font-weight: bold;
font-size: small;
border: 2px solid white;
-moz-border-radius: 6px;
-webkit-border-radius: 6px;
-khtml-border-radius: 6px;
border-radius: 6px;
}
the form:
<div class="box" id="login" style="width: 326px; height: 228px; top: 39%; background-image: url('images/loginBox.png');background-repeat: no-repeat;">
<form id="loginform" action="" method="post">
<fieldset style="display: block">
<legend></legend>
<input id="Nome" class="transparent" type="text">
<input id="Palavra-passe" class="transparent" type="password">
<input id="subLog" type="submit" value="Login">
</fieldset>
</form>
<div class="message"></div>
UPDATE:
The submit button get's hidden when the ajax instruction is called therefore the position changes 65px. To correct this small problem I have removed the margin-top property from the css rule and changed the position with .css('margin-top', 'value'). This way I change the value to the different messages and both get displayed in the same screen position. Thank you.
Well, i don't know exactly how it looks after the ajax response, but if you leave the field empty you just need to take off this line from css
margin-top: 65px;
and it's ok.
look here: http://jsfiddle.net/Ature/2/
P.S. i also added
$('div.message').hide();
to avoid having the div message display before any warning is generated
EDIT - maybe you have other rules affecting your div. if the other rules are loaded before you insert this you can add the line
margin-top: 0px;
to override them.
moreover: remeber to clear your cache when you reload yopur page!
