I have some initialization to be done at page load time, which changes the text of some anchors so that they are consistent with the query string (these anchors are used as criteria selectors, and should be initialized to the criteria contained within the url).
IE and Safari fire the onload event before rendering any elements, so when the event handler synchronizes the anchors, they are rendered with the right contents immediately. Firefox, though, renders the page first, and then fires the handler, which results in the anchors getting their initial values, and then changing to proper selections. I've tried calling my init() method immediately after the anchors are defined in my document - no difference, looks like Firefox is rendering everything as soon as it's encountered in the document.
Is there any way to have my code run before any elements are rendered in Firefox? Currently I've "solved" this by hiding the containing div in the document, and showing it after making changes. This results in the UI visually reloading itself with each new page, which is not very desirable either.
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 cant get my cookie to work. I believe its not my javascript that is wrong. Can anyone take a look to see what i did wrong in my cookie? I have to pages dropdown1.html and dropdown2.html. Both pages have the same exact dropdown list. There is also a javascript file called script.js which makes it so you get an error if you select the same option on the second drop down list as the first. Also in the script.js i have a cookie that should run so dropdown2.html should now what was selected in dropdown1.html Can anyone see if i made a mistake in either my javascript code in my cookie? Right now I am not getting the error message if you select the same option as the first. Ill show all my code incase you need it for reference
dropdown1.html
Code:
Code:
Script.js (this is the part where I cant figure out why the error message does not appear on the second dropdown menu if user selects the same option as the first)
i created a javascript for opening a page on a new window and added it on an html file. i then used the said html file as the source of my iframe on a joomla page. but the javascript isnt working. the said iframe is called Scroll News on this page: [URL]..
I need to execute a JavaScript function "onload". The only problem is I don not have access to the <body> tag as it is a part of the standard page-header include (a separate file). How could I have certain pages execute my function() onLoad?
The function basically just sets the original values of fields so that I can determine if a field has been changed or not, which aleviates unnec. sql update on the backend..
I'm trying to get a popup working on my site. I use headers and was wondering if there is a way to put the onload outside of the BODY tag? My header has the BODY tag in it. I only want the popup to come up on one page and not all the pages that use my header.
I have created a page that takes a person to another page automatically:
<body
However, the script waits for the entire page to load before actually taking the person to the other page. What I need to do is to have a script that takes the visitor to the target page as soon as the page appears (without waiting for ads to load completely). How can this be done?
Just wondering if anyone knows if it's bad practice to put multiple body tags within one document? I'm using a template system (php) that loads template files into a main template (already containing a body onLoad()), and the content files also have a body onLoad() preloading functions intact. It seems to be working but wanted to know if there is anything wrong with this? What about broswer specific issues?
I'm working in a template environment, and I can't change the <body onLoad> tag (it already had a muti-use function on it.
On the specific page I'm working on, I need some layer visibilities changed (dependant on a cookie) which seemingly can only can be done in the onLoad event.
so I need to add to or capture the onLoad for one page, and no others with a script included in the body data? (and of course it needs to be cross-broswer compliant 5+)
have a function which finds the highest value of an array and im trying to get it to work on 2 arrays.however I dont really know how to do this so the function works fine on the first array but when i try to make it work on the second one it returns the same value as the first array, even though the second array shouldnt contain that value. I have put the code below, the funtion I am working on is findHighestValueIndex and the arrays I need it to work on are highestScoreIndex and highestWeightedScoreIndex.with the thank user button
Im writing a piece of javascript that dynamically adds a link to a page, this is the code i'm using
var newP; newP = document.createElement("a"); newP.innerHTML = "Click here";[code].........
However, it wont work?!?! the link appears in the right place on the page when i remove the line newP.setAttribute("href","http:[url]......);and if i view the source the link is <a>Click here</a> (without any href) so there's got to be something wrong with that line but i don't know what it is.I'm using firefox.
I can get both to work separately. If Iput the slideshow below the menu bar in the body it does not play if I put the slideshow first the menu bar does not appear.
I'm trying to detect the browser in that little box but It's not working. in between the <div> tags I have this code
<script type="javascript"> var browser=navigator.appName var browser_version=navigator.appVersion var version=parseFloat(browser_version) document.write("Detecting Browser..." + browser) </script>I don't even think I'm going to user the browser version so don't worry about that but I can't get this to work. I think I have it right, I was looking at the tutorial on w3schools. Can anyone see a problem? Am I leaving something out?
Edit: oh, very sorry. It seems my tiny little mistake is that script type should be "text/javascript". But now that that is figured out It shows that I'm using Netscape when I'm actually using Firefox 0.o
Is it possible to make a javascript call before "<body onload='...'>"?
What I'm doing is a preview of numerous images in an iframe and I want to resize the iframe to match each picture. Normally I'd use the 'onload' (on the src-page holding the image in the iframe) attrubute, but it's not called until the picture has finished loading. I'd like to resize the iframe before (or at the same time) the image starts loading.
I have a script that I have been using for a while that works with 3 sets of div tags. The first is visible and the second two are hidden. Using a select menu you can swap which div tag is visible by selecting that option.
Now this works fine using <body onload="opts();"> to call the function the only problem is that the page I am running this script on has a lot of images and the second two tabs are visible until the page has completely finished loading. This is only for a matter of a second or two but still a problem.
I am not very smart when it comes to JavaScript and I have messed around with adding window.onload = opts(); to the script but kind of unsuccessful. This works in the sense that the second two sets of div tags are invisible from the start of loading the page. There are only two problems with this solution.
1. The script isn't functional (can't swap visibility on div tags) until the entire page has finished loading. -- I can live with this if I have to
2. There is a javascript error message in IE 'null' is null or not an object. This could potentially scare some people away when they see they yellow triangle in the lower left-hand corner of the window.

Is there a substitute to <body onload="validate();"> i.e. I need to call a JS Function on load of a page, but without using <body onload> I've tried window.onload, but it didn't work. Is there a way to do this?
I'm building an ecommerce store that will not allow me access to the <body tag... Is there any way to load the onLoad js call another way?
I tried putting a layer with a high z-index and a clear pixel stretched out in it... I've tried the call as onLoad and as mouseover... I can't get it to work. What am I missing? If you'd like to see my mess, it's here:
we are going to have our customers insert some code onto there page and it load out application.instead of telling them to manually change there body tag I want the script to do it for them.
