Same Image. Onload Runs Again Changing Style.Width!
Aug 27, 2005
I change image.style.width inside a image.onload function. And surprisingly, I found that it runs the onload function on the same image again with the new style.width value. Javascript treats this as a new image! This is the same old image.
Is there a way to pervent it from runing onload the second time?

Been trying to get a short script I wrote to work 100%. Basically it checks to see if the main page image is =>375px and if it is shunts the text down below it. Its not a live site yet and due to it being so short I thought I would just copy and paste it here:
function checkImage(imageId) {
if(document.getElementById) {
var id = document.getElementById(imageId);
[code]....
The problem is with IE6, it randomly decides not to work without any sign from the debugger that anything is wrong. This is my first time using onLoad with an image, is there any quirks with it such as page load order (e.g. if the image finishes loading before the text loads this wouldn't appear to run?).

I want to set the width of a div to be the same width of the image inside the div.The following code works great. But...The images are different widths, so both wrappers are set to the width of the first image. Without having to add an ID to each wrapper or image, can the wrapper width be set to the image width using the name of the image as the unique identifier?
jQuery:
$(document).ready(function(){
var newWidth = $('div.wrapper img').attr('width');
$('div.wrapper').width(newWidth);
});
HTML:
<div class="wrapper">
<p><img src="image1.jpg" width="200" /><br />
Caption</p>
</div>

I have got the following CSS-Box, with those properties in my styles.css:
.panorama {
float:left;
overflow:hidden;
}
[Code]....
But when I want to read out this information afterwards, my function doesnt work:
console.log($('.panorama').css("width")); This delivers me 0px.
Why doesnt it bring me the 1641px?

So I didn't think this would be very hard, but I keep running into problems.
I have:
function changeCSS(idName, newClass) {
document.getElementById(idName).className=newClass;
}
And then:
<p id="Link1" onmouseover="changeCSS(Link1, '#profileNav .hoverNav');" onmouseout="changeCSS(Link1, '#profileNav p');">Link1</p>
I get the error "Link1 is not defined" though.
Anyone know why this is happening? Or a different way to achieve my main goal which is to change Link1's css class.

i'm new to jquery and am not real familiar with javascript. I have a color picker on my page that puts the hex value in an input box. I'm not familiar with jquery or javascript in general. I would like to be able to take the hex value and use it in updating a style of a div onkeyup or onchange...say the border color for example. Something like this...but this isn't working.
<input type="text" id="colorfield1" onFocus="ddcolorposter.echocolor(this, 'colorbox1')"> <div id="colorbox1" class="colorbox"></div>
<br><br>

I am building a schedule web page and before I just had it use plain static HTML and CSS to control the styling. I wrote some javascript that goes through the table's rows, then cells (double for loop), and if the cells innerHTML == "" then the style class is changed. I do have some working code, however it only works in IE. Here's a copy of the script:
<script type="text/javascript">
for (var i = 0; i < document.getElementById('table').rows.length; i ++)
for (var j = 0; j < document.getElementById('table').rows(i).cells.length; j ++)
if (document.getElementById('table').rows(i).cells(j).innerHTML == "")

I have an internal web app that displays some images except they are really big and the app goes super slow and I only have 12 pictures for my test. Sometimes there will be a hundred or more. So is there a way through javascript that I can create thumbnails other than just changing the width and height of the large file?

How to change style on a series of divs (with similar structure but different content) *only if* all the children are visible (that's using visibility, not display).
Sample div:
<div class="h">
<p class="a1">text</p>
<p class="b2">more text></p>
<p class="b3">text text</p>
<p class="a4">text...</p>
<p class="link_display_none_visibility_visible">div name</p></div>
I think it needs to use contents(), but not sure about handling node numbers.

Ive got a small image of a power button and when pressed the inner section on the button changes to yellow, but when its pressed down Im also trying to get part of my H1 (main header logo title) to change to yellow.
Ive created a span with an id surrounding the letters of the H1 that I want to change, the id being : "power";
The javascript that I have come up with so far and works is as follows:
<img id="poweron" src="http://www.sitepoint.com/forums/images/power.png" alt="Power on button" onmousedown="this.src='images/poweron.png';" onmouseup="this.src='images/power.png';"/>
I understand Im not really supposed to be using inline JS, and I know Ive got to create a function for the onmousedown event to trigger changing the H1 text, so am I under the right impression that the JS so far written is redundant and will have to be re-written so thats contained within a script placed just before the closing </body> and an external script for invoking the main function ?
