OnLoad And Onchange Affect Each Other
Mar 15, 2009
I'd like to ask why the onLoad and onchange affect eachother ? How i can avoide that?
<body onLoad="checkCookie()">
and
<select name="province_state_territories" id="state" onchange="setCities();">
when i use the above at the same time, the search function have not another option to choise. It means the option for selection have not values. Because i want to use the "<body onLoad="checkCookie()">" to check my cookie and decide which Language i will use.

Say I have script that looks a bit like this:
Array.prototype.getValue = function(ind, dir) {
if (dir !=0) ind[ind.length-1] += dir;
// more script
}
screens = [...// a big array
fnd = [1,2,3];
// 1.
a = findStart(fnd);
// 2.
b = findEnd(fnd);
findStart = function(cs) {
return screens.getValue(cs, 1);
}
findEnd = function(cs) {
return screens.getValue(cs, -1)
}
As I go from 1. to 2. the value of fnd changes. I don't understand how a
locally scoped variable might be affecting a global one.

I don't know how to select an element inside other elements, like div's. I have my html site like this:
<div id="container">
<div id="top"><h3>Title</h3</div>
<div class="desc">
Lorem Ipsum dolor set...
</div></div>
<div id="container">
<div id="top"><h3>Title</h3</div>
<div class="desc">
Lorem Ipsum dolor set...
</div></div>...so on...
I want to click on any h3-tag and the jquery should open the next div with class desc. At the moment I use this script:
$(document).ready(function(){
$('.desc').hide();
$('h3').click(function() {
$(this).next('.desc').toggle(400);
return false;
});
});
I absolutly dont know what to change inside the script to affect the next div with class desc.

[URL] You see those social network icons under the product description div? When the mouse rolls over the right edge I want a drawer affect that pulls the icons into view and lets the user click one of the social links. When the user rolls his mouse away from the section, the drawer should return to its position.

I need a JavaScript script to only affect a certain section of my page. Is it possible that I could put that part of my page in a DIV or a FRAME to get this to work? How would I do this?
Here is my script:
As you can see, that would choose a random link from my entire page. If I want to make it choose from a section of my page, what would I do? (there are a lot of links on this page, and I don't want to assign number to each and every one of them, and then choose a random number)

I have a form that is validated using the DOM. If a user attempts to submit this form before completing all required fields the fields turn red. The only drawback to this is the reading the text in the fields can become difficult. One thing I was hoping to do was to have the text associated with each form element turn red insteadof the field.
Each form element's text is enclosed in a <label> tag and I figure setting that tag's font color to red would be easy enough to do...if I knew how to reference it. That's the thing, I'm not sure how to reference it.

Is there something that will update as soon as the user changes information in a textbox as appose to what onChange does, which is update once the focus has been taken off of the textbox? I am writing a custom cart and I am using AJAX to update the price according to how many they are ordering, I was hoping to have it update the price as soon as the user put in the volume, but it doesnt update until the user clicks somewhere else on the page.

[code]I'd like to click FirstDrilldown and have it display div#SecondDrilldown. Then I'd like to be able to click SecondDrilldown to fire off a different click handler. The problem is that the click handler bound to the FirstDrilldown intercepts the click. I'm fairly sure I could bind and unbind the click FirstDrilldown click event but that's kind of an inelegant solution.Is there just a way to just promote the SecondDrilldown click event to have a greater precedence than the one associated with FirstDrilldown?

I would like to ask if the following is possible.
1) I have one hundred identical links on my page
2) I have a function that changes a clicked link to "display: none" (using the toggle functioon)
Is it possible for me to set it up so that only the link that is clicked (that is, only one element) gets affected? I don't want to click and have all the links disappear.. just the one that was clicked.Would this code below work in all browsers? [code] And secondly, may I ask whats the difference between $("a") and $('a'). I've seen people use single quotation makrs and double. Which is better ??

I'm developing a site in HTML 5 and SVG, just for the heck of it. I have a portion of the site that uses the <embed> tag to load a new SVG when you change pages, which, in theory, would let me do effects between pages. However, no matter what I try, there is a white flash as the new SVG is loaded into the page. So, I figured I would make the embedded area invisible until it loaded, which was no big deal. But when I tried it, the flash still happened! So, I built a pause function to wait a bit longer. It sill flashes. Anyway, 7 hours later, I've determined that the newly embedded page isn't actually being downloaded and embedded until the end of the changePage() function is reached.
Here's my java script:
var close1;
var close2;
var bar;
var svgLoaded = false;
[Code]......

Not a huge issue, more of an annoyance, but when firing
Code:
Effect.Appear('whatever');
it only works when
Code:
display:block;
is an inline style on the target element and not when it's applied via an external style sheet. Is there a fix for this or is it just a quirk of the library?

I have 3 images that I would like to display horizontally. I need a default text to appear first when the page loads. When an image is clicked on, the new text should slide down covering the default text. When another image is clicked on that text should slide down and cover the previous image's text.Right now the script only allows a vertical display of the images and I can't put the sliding text in a specific place.Here is the CSS
Code:
<head>
<style type="text/css">

was wondering if it made sense to optimize the comparison order inside an if() statement if one of the comparison targets is a function call eg:
var a = true,
b = function() {return false;};
if (b() || a) {...}
if (a || b()) {...}
would the second statement run faster because it would theoretically never need to call b() in this situation? can the eval order be relied on? does this depend on the js engine/internal optimizations?

I am trying to put together a proof of concept. What I am trying to prove is that a back button affect can be accomplished using DHTML and an IFrame. Here is the concept, as the user changes data, that data can be written to an IFrame. Then, when the user hits the back button, contents can be taken from the IFrame using history.back() since the IFrame should remember the content written to it just like a page would.
Here is my problem. The below code writes the content entered into the text box into the IFrame. But when I click the button to execute the history.back(), the value returned is undefined.
I think my problem might be that the code which writes the contents of the text box to the IFrame is doing that dynamically, so the page is not caching it. If this is correct, how can I write the dynamically entered content from the text box to the IFrame so it can be cached by the IFrame window? Code:

I wander what gets loaded the fastest (1-2 or 3) in what succession:
<head>
<script type="text/javascript">
function andAction() {
// doing stuff
}
</script>
</head>
<body onload="andAction();">
<script type="text/javascript">andAction()</script></body>
just in the head and nothing more
This I am sure off:
<head>
<script type="text/javascript">
window.onload = function andAction() {
// doing stuff
}
</script>
</head>
<script type="text/javascript">andAction()</script></body>
just in the head and nothing more (should be 1)
Third and last which is faster:
body onload or window.onload

Can I target the element and base an onChange outside of directly calling it in the element tag?
Due to the nature of my script, the best I can do is wrap a tag around the element.
example of what I am trying to do
Code:
<script>
document.form.field1.onchange = function();
<script>
And if this might work, can I call it in the head or must it come after the element.

I'm seeing a difference in behaviour between
window.onload = f();
and
<body onload="f();">
Specifically, window.onload appears to fire before all the elements of
the page have been rendered. As the difference is consistent across
IE/Moz/Opera, I'm assuming it's deliberate - can anyone point me
towards where this behaviour of window.onload is defined in the
documentation? TIA. Code:

I have a situation where a context menu is being added to the DOM dynamically when a user right clicks on a control on the page. The div that gets added does not have an id set but the div does have a unique class. WhatI need to do is intercept the addition of the div and add a hover affect to some child nodes. Specifically any children that are <a> nodes. So far this is whatI have for adding the hover affect, but i'm not sure where it needs to go or howI link it to the event raised whan a new element is added to the dom.
$(
'div.context_menu_main').find('div a').hover(function() { $(this).addClass('context_menu_hover');
}, function() {
$(this).removeClass('context_menu_hover');
});
I have no control over the div itself as its part of a third party control soI am unable to add an id.

I've set up two buttons to dynamically load in content. However for some reason the content only loads on the first time you click a button. The transition function does receive the correct variables however. The fade0ut animation also doesn't take affect whilst the replaceWith() function is inside the transition function.

I understand that the onchange event occurs when the value of a
form element changes (and after the element loses focus).
But what about the case where the value of a text box (for example)
is changed from a javascript function? Is an onclick event triggered
in such a case? I find that this is not happening in IE.

I have a big problem with a simple event : onchange!
If I write this page:
<html>
<body>
<form id="vu">
<input id="var01" name="var01" size="5" onchange="return false;"/>
</form>
</body>
</html>
everything is ok in IE (I can't leave the input zone !) but nothing happens in Firefox!
It looks like the event is not fired or...
Do you have any clue?

I have a button that opens a calendar and populates a text box. I use
the onclick event to open the calendar.
Now the textbox has a onChange event that calls a function. The
onChange fires perfectly if I type the date on the textbox, but if the
calendar changes the date on the field then the onChange event doesn't fire.
I even try the following, but it seems that both functions run at the
same time and the value on the field is never picked up.
