Can a link have both an onclick jquery and javascript event? - javascript

I have a link that jQuery listens to, and if clicked it will toggle another div. The link also has an onclick javascript action. When I click the link, the div I want to toggle shows, but the javascript doesn't execute.
Is it possible to get the javascript to execute AND have jQuery toggle the div?
If so what would I put in the jQuery code to allow the link to execute the onclick javascript action?
jQuery script
$(function() {
$('#links a').live('click', function() {
$("#showall").toggle('slow');
});
});
my link
<div id ="links">
Play
</div>

for me the following is working in Chrome, Firefox and IE. Both pure Javascript (onclick) and jQuery click() get executed.
<html>
<head>
<script type="text/javascript" src="jquery-1.4.4.js"></script>
<script type="text/javascript">
$(document).ready(function() {
$('a').click(function() {
$('div').toggle();
});
});
</script>
</head>
<body>
Click me
<div>
Some div content...
</div>
</body>
</html>

Second page does not work with Codes in the first page

I have a main page that I have loaded another page on it via ajax when document is ready ,also I have a button that when I click It I shows an alert and, I have that button in the second page too. but when i click on it in that page that code does not work ?
how can i solve this problem ?
because I do not want to repeat js codes on the second page ?
here is my first page code :
first page code:
<html>
<head>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.2.1/jquery.min.js"></script>
</head>
<body>
<div class="captcha" style="border:1px solid red;">
</div>
<div class="details1">cccc</div>
<script>
$(document).ready(function(e) {
$(".captcha").load("/secondpage.htm");
$(".details1").click( function()
{
alert('button clicked');
}
);
});
</script>
</body>
</html>
and this is my second page that I have loaded into div with classname captcha:
second page code:
<html>
<head>
</head>
<body>
<section class="details1"> Details </section>
</body>
</html>
When you need to create new elements on-the-fly, you can not use standard click etc. events. Dynamically created elements are not born with the same event handlers as the existing elements. You have to dynamically attach event handlers to newly created elements.
Replace 'click' with 'on'.
$("body").on("click", ".details1", function(){
alert('button clicked');
});

how to click an anchor tag from javascript or jquery

Have an anchor tag, trying to click it from the javascript but not responding, while loading the page it should go to next.php without click anchor tag manually.how can I archive this?
<!DOCTYPE html>
<html>
<head>
<title></title>
<script src="jquery-2.0.3.js"></script>
<script type="text/javascript">
alert("hai");
$(document).ready(function() { $('#about').click(); });
</script>
</head>
<body>
<div>
click here
</div>
</body>
</html>
Use $('selector')[0], as $('selector') returns a jQuery object, so $('selector').click() will fire the click handler, while $('selector')[0].click() would fire the actual click.
$(document).ready(function () {
$('#about')[0].click(); //$('#about').get(0).click();
});
Demo
You can not use javascript to fire click event
It should use
<script type="text/javascript">
$(document).ready(function() {
document.location.href='/next.php'
});
</script>
Here is the code that can help you
$(document).ready(function() {
$(document).ready(function() {
$('a').trigger('click');
});
})
function abc() {
alert("");
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
click me not
If you want the recommended way then use this inside $(document).ready
window.location="where ever you want to go";
If you want the page to go to next.php without clicking then place the window.location directly into $(document).ready(function() { });
Click() function is used when you want to trigger click event. ie. when you want to trigger some action when anchor tag is clicked.
<script>
alert("hai");
$(document).ready(function() {
window.location = 'next.php'; //If you wish the page to automatically go to next page on page load.
$('#about').click( // If you wish to do something clicking anchor
function(){
alert("Hello");
});
});
</script>
$(document).ready(function() { $('#about').trigger('click'); });
Updated:
$(document).ready(function() { $('#about')[0].click(); });

Load the javascript file after loading the ajax

I am using jQuery and Ajax.
HOME.html
<html>
<head>
<script src="jquery.js"></script>
<script src="javascript.js"></script>
</head>
<body>
<div id="div1"></div>
<button>click</button>
</body>
</html>
javascript.js
$(document).ready(function(){
$('button').click(function(){
alert('Button is clicked');
$("#div1").load("test2.html");
});
$("#b2").click(function(){
$("#div2").hide();
});
});
TEST2.html
<body>
<div id="div2">
some content
<input type="button" id="b2" value="hide" />
</div>
</body>
<head><script src="javascript.js"></script></head>
When I click on button, Ajax loads the content in div. But when I again click on button then it is clicked twice. I know why this click twice happens, because I again load the javascript.js file.
If I can't do that then the hide button is not working because the JavaScript loads before the div2, that's why hide button is not working.
SOLUTION:
There is one solution is that I use the hide button code in test2.html instead of in javascript.js But I don't want to do that.
Beacuse this is a demo in my original code this is very difficult to do that.
Is there another solution to this?
Repeatedly re-loading the JavaScript is a bad idea.
If you just want to handle clicks on buttons that are dynamically added, you can do that using event delegation. Remove javascript.js from test2.html entirely, and hook up your handlers like this (e.g., change javascript.js to the following):
$(document).on("click", "button", function(){
alert('Button is clicked');
$("#div1").load("test2.html");
});
$(document).on("click", "#b2", function(){
$("#div2").hide();
});
That watches for the click event on the document, but only fires the associated handler if the event passed through an element in the bubbling phase that matches the selector in the second argument. When firing the handler, jQuery makes it look a lot like you had the handler actually attached to that element, rather than to document.
There's a lot more in test2.html than there should be. jQuery will only append the bit in the body (and run the script, but we're removing that). test2.html should just be:
<div id="div2">
some content
<input type="button" id="b2" value="hide" />
</div>
Side note: If you're going to replace it on the next click, I'd use $("#div1").empty() rather than $("#div2").hide() so that you actually proactively remove the content you're going to replace later, rather than just hiding it.

jQuery stops working after loading content into a div

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.

hide div when page load

I have jquery issue, Kindly see my jquery code:
$(document).ready(function(){
$(".toggle_container").show();
$("h2.trigger").toggle(function(){
$(this).addClass("active");
}, function () {
$(this).removeClass("active");
});
$("h2.trigger").click(function(){
$(this).next(".toggle_container").slideToggle("slow,");
});
});
My .toggle_container is shown always its good, But I want to close it first time, when page load. Can you please provide me any solution?
I dont want to use $(".toggle_container").hide(); function for this problem because when i click on href then .toggle_container should not hide, It should open.
Regards.
You can just add attribute
style="display:none"
to your element .toggle_container.
Then on first call of $(document).ready it will be shown.
The full test example:
<html>
<head>
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.6.1/jquery.min.js"></script>
<script type="text/javascript">
$(document).ready(function(){
$("h2.trigger").click(function(){
$(this).next(".toggle_container").slideToggle("slow,");
});
});
</script>
</head>
<body>
<h2 class="trigger">Toggle</h2>
<div class="toggle_container" style="display:none">Container</div>
</body>
</html>
Note: there`s no $(".toggle_container").show(); on $(document).ready
remove the
$(".toggle_container").show();
from your $(document).ready function.
in html part add style="display:none" for the toggle_container div.
check the #HCK s reply. he is clearly mentioned it..
Once the document gets loaded, a alert box will be prompted "page loaded".
$(document).ready(function(){
alert('page loaded'); // alert to confirm the page is loaded
$('.divClassName').hide(); //enter the class or id of the particular html element which you wish to hide.
});
