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(); });
I have written the following script to print a document:
<script type="text/javascript">
function print() {
window.print();
}
$(".printdoc").click(function () {
print();
});
</script>
and I am invoking the above script by an <asp:button../> as follows:
<asp:Button ID="btnPrint" runat="server" Text="Print" CssClass="printdoc"/>
Every time I click on the button it loads the page again but the query doesn't seem to work.
When I checked the resources , I found the following console error:
Uncaught ReferenceError: $ is not defined
print may collide with the built in print function. So let's call it printPage.
<script type="text/javascript">
function printPage() {
window.print();
}
</script>
In additional to Rahul's solution for referencing jQuery, by default asp:Button will postback to the server when clicked. So switch to a regular button.
<button type="button" onclick="printPage()" runat="server">Print</button>
You can leave the runat attribute off if you want, it's only necessary if you want to refer to it from the code behind.
If you really wanna use the asp:Button, you can do this:
<asp:Button ID="btnPrint" runat="server" Text="Print" OnClientClick="printPage(); return false;"/>
The return false; will prevent the postback. But I don't see much point in using asp:Button for client side things.
You need to put the reference of Jquery in your code:
<script language="JavaScript" type="text/javascript" src="/js/jquery-1.2.6.min.js"></script>
<script language="JavaScript" type="text/javascript" src="/js/jquery-ui-personalized-1.5.2.packed.js"></script>
<script language="JavaScript" type="text/javascript" src="/js/sprinkle.js"></script>
As mason has already answered the rest, you need to create a regular button instead of asp:button as asp:button will postback to the server everytime it will be clicked.
I have a web page that brings up the print dialog on load. After clicking print (and focus returning to the page) I need a link to be clicked. Does anyone know a way using jQuery or Javascript that I can do this?
This is what I currently have, but it doesn't seem to be working:
<script type="text/javascript">
$(document).ready(function() {
window.print();
$("body").bind("focus", function(){ $("#logout").click() });
});
</script>
try this:
<script type="text/javascript">
$(document).ready(function() {
if (window.print())
location.href = $("#logout").attr('href');
else
location.href = $("#logout").attr('href');
});
</script>
and
<body>
<a id="logout" href="http://www.google.it">Link</a>
</body>
I have one popup window, when user opens and closes popup window simultaneously, it is giving script error. Below code is used in popup window.
<html>
<head>
<script src="../../StaticContent/Scripts/jquery-1.7.2.min.js"
type="text/javascript"></script>
<script src="../../StaticContent/Scripts/jquery-ui-1.8.20.custom.js"
type="text/javascript"></script>
<script type="text/javascript" language="javascript">
function CloseWarning() {
return "Do you want to close the window";
}
function onload()
{
}
</script></head>
<body onbeforeunload="return CloseWarning();" onload="onload();">
//Some html
<script type="text/javascript" language="javascript">
$(document).ready(
function() {
//Some code
});
</script>
</body>
</html>
I have tried degubbing, it is giving error at $(document).ready() line. I think because of closing the popup window before fully loading HTML is causing this problem.
Any clues???
you have ()() as double in the function declaration. change like below.
function CloseWarning(){
return "Do you want to close the window";
}
I'm juuuuuust trying to get an pop up displaying test when the document is ready. I've managed to get google maps working on another page but somehow this is a lot of pain.
Here's the code:
<html>
<head>
[...]
<script type="text/javascript" href="https://ajax.googleapis.com/ajax/libs/jquery/1.5.0/jquery.min.js"></script>
{literal}
<script type="text/javascript">
$(document).ready(function () {
alert ("test");
});
</script>
{/literal}
</head>
[...]
</html>
What should I do to get that popup message? I also tried copy pasting from my working jquery page without much success.
Changing <script href=...> to <script src=...> works like a charm for me.
Does you javascript is enabled in your browser ?
You can type this:
$(function() {
alert("test");
});
