I need to basically add this to my page:
<body onload="document.getElementById('WeddingBandBuilder').focus()">
However due to my template I cannot change the tag. So is there a way to do the equivalent with a script in the < head > tag or something?
Thanks!
<script>
window.onload = function() {document.getElementById('WeddingBandBuilder').focus()};
</script>
You should always be careful there isn't already a window.onload defined. I've been burned a number of times by assuming I would be the only one attaching things to <body onload="..."> or window.onload.
See this answer and comments for a solution to this issue.
Use a JS library like jQuery or Prototype and create an external script file with something like this:
for jQuery:
$(function() { $('#WeddingBandBuilder').focus(); });
for Prototype:
Event.observe(window, 'load', function() { $('WeddingBandBuilder').focus(); });
I might check if that page has already included jQuery? If so, you can do something like this:
$(document).ready(function() {
$('#WeddingBandBuilder').focus();
});

Here is the code i am using to change value of html element ***
<a class="classname" href="Vtech.com"> This text to be chnage</a>
<script type="text/javascript">
document.getElementsByClassName("classname")[0].innerHTML = "aaaaaaqwerty";
</script>
how can I change this text on page load instans
Seems you need to add DOMContentLoaded or put your script before </body>
Native JavaScript solution
document.addEventListener("DOMContentLoaded", function(event) {
document.getElementsByClassName("classname")[0].innerHTML = "qwerty";
});
Add your script before </body>
Version with jQuery
$(funtion(){
$(".classname:first").text("qwerty");
});
You can use css selector, but it can be not safe, because this method return first occurance:
document.querySelector(".classname");
By the way, almost all developers use some js framework: jQuery, prototype, extJs, etc
$(document).ready(funtion(){
$(".classname").text("aaaaaaqwerty");
});
Using jquery (I refered to jquery, since you have tagged it in your question), you could achieve this like below:
$(funtion(){
$("a .classname")[0].text("aaaaaaqwerty");
});
You could use this
document.addEventListener("DOMContentLoaded", function(event) {
document.getElementsByClassName("classname")[0].innerHTML = "some texts";
});
Using jQuery
$(document).ready(function(){
$(".classname").eq(0).val("aaaaaaqwerty");
});
I have noticed that document.ready not prepending <div> tag.
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<script type="text/javascript">
var shadow = $('<div id="shadowElem"></div>');
var speed = 1000;
$(document).ready(function() {
$('body').prepend(shadow);
}(jQuery));
</script>
- In console, There are no errors.
This is truly frustrating now and any help will be really appreciated.

try this:-
var shadow = jQuery('<div id="shadowElem"></div>');
jQuery(document).ready(function() {
jQuery('body').prepend(shadow);
});
for more information check This link
I suppose that problem is in document.ready().
Try this instead:
$(function() {
$('body').prepend('<div id="shadowElem">Test</div>');
});
I would look into a conflict with prototype.js and jQuery. You may need to try jQuery.noConflict();
I would suggest using one library instead of both. Of course you will need to use a jquery lightbox instead, from what I see on your link.
I want to call a jQuery function from an HTML <body> tag. Here's my HTML:
< body bgcolor="#ffffff" onLoad="???" >
How would I call a jQuery function when the page is loaded? My jQuery function looks like this
jQuery(function($){
var input_id;
//code
});
whatever code you write in the below method(block) would be executed automatically after the DOM load. You need not call this from HTML component again.
$(document).ready(function() {
//your code
});
This topic has been covered here before.
You are most likely looking for
$(document).ready(function() {
var input_id;
//code
})
Or
$(window).load(function($) {
var input_id;
//code
});
If you are curious about the difference between these two, see the JQuery documentation on the topic.
Also note that <body onload="">, which you seem to be trying to use, is generally not compatible with the above JQuery.
$(function() {
// code
});
This is shorthand for document.ready() so it will wait for the body to finish loading before executing.
HTML: You're on the right track, but you do not have to have put JS in the body tag. See the JS options below:
<body bgcolor="#ffffff">
JS
$(window).load(function($) {
functionA(arg1, arg2, arg3);
});
This will fire up functionA() once the DOM including graphics have fully loaded.
OR
$(document).ready(function($) {
functionA(arg1, arg2, arg3);
});
This will fire functionA() once the DOM has loaded and before any graphics finish loading.
As of Jquery 3, the following syntax is depreciated:
document.ready(function(){
//code
});
The recommended alternative in Jquery 3 is to use the following syntax (which in previous versions was just considered a shorthand syntax):
$(function(){
//code
});
Here is is the official Jquery explanation for why the first syntax was depreciated and is no longer recommended (https://api.jquery.com/ready/):
... The selection [of document] has no bearing on the behavior of the .ready() method, which is inefficient and can lead to incorrect assumptions about the method's behavior.
document.ready(function($){
// here you go
})
I´m having a normal JavaScript-function and want to use the Variable (myVar) also in my jQuery Code - is this possible? and how?:
<a onclick="showtitle(abctitle);" href="#">Testlink</a>
<script>
function showtitle(myVar) {
myTitle = myVar;
}
$(document).ready(function() {
alert(myTitle); //I would like to alert "abctitle"
};
</script>
Firstly, don't mix DOM0 inline event handlers with jQuery. Separate your markup and your logic.
If you use a data- attribute you can put your variable's content in your HTML, and then extract that in the event handler:
<a id="test" data-foo="mytitle" href="#">Testlink</a>
and then:
$(document).ready(function() {
$('#test').on('click', function() {
alert($(this).data('foo'));
}
});
In this code the alert won't appear until the link is actually clicked on, of course.
I believe #Alnitak has a great answer. But if you are just looking to solve the question you asked, wrap abctitle in single quotes and make myTitle a global variable:
<a onclick="showtitle('abctitle 2');" href="#">Testlink</a>
<script>
myTitle = "abctitle";
function showtitle(myVar) {
myTitle = myVar;
}
$(document).ready(function() {
alert(myTitle); //I would like to alert "abctitle"
});
</script>
Also, your document ready function was missing its closing parenthesis )
Working example here: http://jsfiddle.net/CbhxY/
UPDATE
Working example on jsfiddle did not work so well. Try this: http://jsbin.com/ohedab/1/
The JS Bin example also adds the alert call in the showtitle function.
you can do with this
function showtitle(abctitle){
alert(myTitle); //I would like to alert "abctitle"
}
I'm trying out jQuery for the first time, and I'm not sure how to make it work properly. I've included the following code near my opening <head> tag:
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.8/jquery.min.js" type="text/javascript"></script>
Followed by the following jQuery code:
<script>
$('.darkmask > img').hover(function(){
$(this).parent().toggleClass('darkmask-hover');
})
</script>
Unfortunately, this code doesn't work when I try it in a browser, or in JSFiddle. However, when I set JSFiddle's framework to load jQuery itself, rather than loading jQuery through my own code, the animation works properly.
Am I loading jQuery wrong? If so, what's the right way?
PRoblem is, your code in JSFiddle is executed on the loading on the page. In your code instead, the execution happens when the HTML elements are not yet loaded because it's in the HEAD, so the selectors like .darkmask actually refer to... nothing.
The solution is to use:
$(document).ready(
function()
{
... your code here
}
To ensure that it is executed when the page is loaded and ready, all the HTML elements are there and therefore JQuery selectors can operate on something.
Are there any HTML elements when the code is executed?
Try:
$(function () { // this function executes when the page loads
alert(x);
// put your code here
});
Wrap your entire code in the following:
$(document).ready(function() {
//ALL CODE GOES HERE
});
Wrap your code in:
$(function() {
.... Your code here ...
});
It will mean your code is executed after the DOM tree is loaded.
You do need to wrap your jQuery code within the ready function, like this:
$(document).ready(function(){
// put your code here.
});
Also make sure your script tags have type="text/javascript" as an attribute otherwise it won't get run as javascript.
