I'm new to HTML and JS so i would be very grateful if someone helped me with the following - I have a normal page that contains a plus (+) button:
<button style="background-color:#0099CC" id= "firstbutton" type="submit" data-role="button" data-theme="b">Add
<script>
$(function(){
$('#firstbutton').click(function(){
$(this).before('<button type="submit">add</button>');
});
});
</script>
I want to add another button above the add button when I click on the add button. Any help?
Use following jquery code:
$("button").click(function(){
$(this).parent().prepend("<button style=\"background-color:#0099CC\">Add</button>");
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<button style="background-color:#0099CC" id= "firstbutton" type="submit" data-role="button" data-theme="b">Add</button>
Using jquery which is a javascript library, you need to first download it or you can include this in the head section of your HTML
<script src="http://code.jquery.com/jquery-1.11.3.min.js"></script>
after doing it inside the script tag which will be below the above inclusion:
<script>
$(function(){
$('#firstbutton').click(function(){
$(this).before('<button type="submit">add</button>');
});
});
</script>

I could be missing something, but I am not sure why my JQuery.click event is not working with the corresponding button.
HTML CODE: <button id="jan7" type="button" class="btn btn-dark btn-sm">Let's Check!</button>
JS/JQuery CODE:
<script>
$(document).ready(function() {
$("jan7").click(function(){
alert("The button was clicked");
});
});
</script>
On my HTML page, here is the order of the scripts I am calling (which is assume to be correct):
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.2.1/jquery.min.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/popper.js/1.12.6/umd/popper.min.js"></script>
<script src="https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0-beta.2/js/bootstrap.min.js"></script>
<script src="countDown.js"></script>
Is there something obvious that I am missing?
The button is using Id =jan7
jquery need "#" when you are using selectors
<script>
$(document).ready(function() {
$("#jan7").click(function(){
alert("The button was clicked");
});
});
</script>`
be sure if you have it as ID or as a Class.
In case it is a class you should use $('.jan7') or in case its an id $('#jan7')
The target element you want to click on could be something like this.

Hi i am trying to append the div to the button with the corresponding to that button text
(i.e. In the case of below example the button text is "Download" so i am appending the div class as new and if the button text is "Upload"
i will append some other div class).
And for the appending div I am using wrap API.
Here is my code
<!DOCTYPE html>
<html>
<head>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.1.1/jquery.min.js"></script>
</head>
<body>
<button class="btn" title="run">Download</button>
<script>
$(document).ready(function() {
var buttontext = $("button").text();
alert(buttontext);
$('button[text="Download"]').wrap("<div class='new'></div>");
});
</script>
</body>
</html>
I am trying to get the button text like this button[text="Download"] but it is not working.
Finally i want the output something like this
<div class="new">
<button class="btn" title="run">Download</button>
</div>
Any help will be appreciated.
You could user jquery's contains method:
$(document).ready(function() {
$('button:contains("Download")').wrap("<div class='new'></div>");
});
Here is a working codepen:
http://codepen.io/egerrard/pen/MJpwdz
And the documentation on contains:
https://api.jquery.com/jQuery.contains
It may sound trivial but I am unable to do it.
Here is the simple code : what's wrong I am doing here ?
Is it like I have misunderstood the function? If yes, please correct me.
<html>
<head>
<script type="text/javascript" src="jquery.js"></script>
<script type="text/javascript">
$(document).ready(function(){
$(".button").click(function(){
jQuery('#id').append('<select></select>');
});
});
</script>
</head>
<body >
<input type="submit" class="button" id="id" value="submit"/>
</body>
considering your own code you can simply write
$('#id').after('<select></select>');
generally append works with a container since #id is associated with a button so it will not work. use div/span if you still want to use append, but if you don't want to .after() works fine.
you have no container/element in your body that will hold the newly added select, add a container in your html like this with id="id"
<body >
<div id="id">
</div>
<input type="submit" class="button" value="submit"/>
</body>
DEMO
Does #id exists in the document?
Do you want to add <option> to <select> ?
$(document).ready(function() {
$(".button").click(function() {
jQuery('body').append('<select><option value="1">One</option><option value="2">Two</option></select>');
});
});
Fiddle - http://jsfiddle.net/XVmuZ/
If you want to add it to #id then make sure it exists (like in rahul's answer)
Fiddle - http://jsfiddle.net/XVmuZ/1/
fisrt thing don't use submit button because it will postback your page so jquery will not work.
try this code
<html>
<head>
<script type="text/javascript" src="jquery.js"></script>
<script type="text/javascript">
$(document).ready(function(){
$(".button").click(function(){
$('#ddl').append('<select><option>abc</option><option>def</option></select>');
});
});
</script>
</head>
<body >
<input type="button" class="button" id="id" value="submit"/>
<div id="ddl">
</div>
</body>
For example I have the following HTML named index.html:
<html>
<head>
<style>
#content { float:left; }
#sub { float:right; }
</style>
<script src="http://code.jquery.com/jquery-latest.js"></script>
<script type="text/javascript" src="action.js"></script>
</head>
<body>
<h2>Test de</h2>
<div id="content">
Content
<button class="loadSub">Load</button>
</div>
<div id="sub">
Sub content
</div>
</body>
</html>
And a simple JS file named action.js:
$(document).ready(function(){
$('button.loadSub').click(function(){
$('#sub').load('test.html');
});
$('button.hide').click(function(){
$('#sub').fadeOut('slow');
});
});
As you can see, when I click the button .loadSub the div #sub will be loaded with the new content from test.html:
<h2>This is the sub content</h2>
<button class="hide">Hide</button>
I got two problems here:
Firstly, the .loadSub button did successfully load the the div of id subcontent, but the .hide button did not work.
Secondly, after I had tried inserting
script type="text/javascript" src="action.js"
inside test.html, the hide button worked and faded out its content. But then in turn, I found out that the button loadSub no longer functioned. I couldn't load the subcontent again.
Is there any other way around to just once declare source of js file and make my button.loadSub work whenever I click it? Could anybody please explain the problem and give me a hint to fix it.
You're loading dynamic HTML into your page. This means that at the time you called $('button.hide').click(), the button.hide element did not exist in your page yet, so the click handler could not be attached.
You might want to try doing a delegate attachment instead.
$('#sub').on('click', 'button.hide', function () {
$('#sub').fadeOut('slow');
});
On the first page, put this. You can insert my JQQuery code into your action.js file. On the second page, the one you are loading into your div, put the second Jquery code I added.
On First page:
<html>
<head>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.min.js" type="text/javascript"></script>
<style>
#content{float:left;}
#sub{float:right;}
</style>
<script type="text/javascript">
$(document).ready(function(){
$(function(){
$('.loadSub').click(function(){
$('#sub').show();
$('#sub').load('test.html');
});
});
});
</script>
</head>
<body>
<h2>Test de</h2>
<div id="content">
Content
<button class="loadSub">Load</button>
</div>
<div id="sub">Sub content</div>
</body>
</html>
On the second page (the page that's loaded into the div, add this:
<script type="text/javascript">
$(document).ready(function(){
$(function(){
$('.hide').unbind("click").click(function(){
$('#sub').fadeOut('slow');
});
});
});
</script>
<h2>This is the sub content</h2>
<button class="hide">Hide</button>
The hide button isn't on the page when you try to bind the event so it is never registered.
Change it to use on like this (assuming version 1.7+)
$(document).on('click', 'button.hide', function(){
$('#sub').fadeOut('slow');
});
or delegate if an older version:
$(document).delegate('button.hide', 'click', function(){
$('#sub').fadeOut('slow');
});
This attaches the event handler at the document level so will work for any new content added to the page.
I do something like this:
$("#id1").html(data);
I refill a div with html but when I try to get the html of a child of this refilled div I get an empty string although it has, it's like the old child is still there but without html.
Edit:
I tried to reproduce my problem, here is the html: (click 2x times on refill and after click open you will see that nothing is going to happen)
<html>
<head>
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js"></script>
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jqueryui/1.8.5/jquery-ui.min.js"></script>
<link type="text/css" rel="stylesheet" href="http://ajax.googleapis.com/ajax/libs/jqueryui/1.8.5/themes/dot-luv/jquery-ui.css"/>
</head>
<body>
<script type="text/javascript">
$(function(){
$("#r1").click(function(){
var x = $("#main").html();
$("#main").html(x);
});
});
</script>
refill
<div id="main">
<a id="a1" href="#" >open</a>
<script type="text/javascript">
$(function(){
$("#a1").click(function(){$("#forDialog").dialog();});
$("#a2").click(function(){$("#forDialog").dialog('close');});
});
</script>
<div id="forDialog">
hi
<a id="a2" href="#" >close</a>
</div>
</div>
</body>
</html>
I'm generating this javascript dynamically so the scripts that register a1.click and a2.click need to be inside the main div
I'm not quite sure as to the exact goal of your code, but I can make 3 general suggesions:
Use .delegate() to attach to once and future elements.
You can .hide() the HTML for you dialog box.
You can prevent the page from refreshing when a link is clicked using event.preventDefault(); in the click handler of that link.
Applying those suggestions to your code results in the following working code:
<script type="text/javascript">
$("body").delegate("#a1", "click", function(){
$("#forDialog").dialog();
});
$("body").delegate("#a2", "click", function(){
$("#forDialog").dialog('close');
});
$(function(){
// Hide HTML for the dialog.
$("#forDialog").hide();
$("#r1").click(function(event){
var x = $("#main").html();
$("#main").html(x);
// If you don't want the page to refresh by clicking
// on this A element, use the following:
event.preventDefault();
});
});
</script>
refill
<div id="main">
<a id="a1" href="#" >open</a>
<div id="forDialog">
hi
<a id="a2" href="#" >close</a>
</div>
</div>

The old sub-DOM under the element will be gone after you reset its content with .html(stuff). It may exist floating around in memory somewhere, but it's detached from the DOM and you can't get at it.
