Calling Multiple Functions With A Single Body Onload Call?
Jul 19, 2011
I have a web page that has a short flash show on it, then it redirects to the main site index page, using a setTimout in body onload. That was all working fine. Now I need to add an OS detection function to redirect iphone and ipad users immediately (bypassing the flash pape). So, I have 2 functions that need to be in the body onload. I figured the logical thing to do would be to write another function that calls the first 2, then put that one in the onload. But now nothing is working. I have played with in for an hour with no luck.
Just as a note: Original, before I had to add the OS detection, there was just the delayer function, and it was called thusly:
I have tried a number of variations, like adding "javascript:" in front of the first call, and returning True of False from the first function, but Icant get the second function to fire after the first one has.
by using alerts, and wathcing what IS occuring, I know that the first is being called, but the second isn't.
I did this once some years back, but I can't seem to rember how I did, it, and none of the example that I have located have helped, so can anyone point me in the right direction?
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'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:
I have a function that needs to get the innerHTML between the body tags once the page loads. However, when I put the JS in the header and call the function using window.onload, it gives me an error. If I put the javascript in the body, it only gets the code above the <script> tag. And I am going to call a server side user control that will put the javascript on the page, so I don't even know where in the page it will go.
It only works when I use the onload attribute in the body tag. i.e <body onload="javascript:fcn_name">
I am using document.body.innerHTML to get the html within the body tags. I tried using document.body.onload and other ways of doing it. Since I am trying to integrate this function within an already existing site, I cannot go through the hundreds of pages and modify the body tags.
Is there an alternative to using the onload attribute of the body tag?
I'm trying to make a table that will hide multiple rows in single js functions... now I put together a way to do it, but it requires multiple id declarations in the functions, is there any way to do it with classes instead of IDs, so that I can have a blanket class that I can use?See:
Code: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml">[code]......
I have been trying to load a javascript function from the body onload html tag, but I only want the function to load the first time the page is loaded: I have investigated but haven't found anything that works.. I thought about cookies, but what if the user's disable them?
My code:
//I want to call the Toggle function below only on the 1st time the page is loaded:
<script language="javascript">
function Toggle(item) {
obj=document.getElementById(item); visible=(obj.style.display!="none") key=document.getElementById("x" + item); if (visible) { obj.style.display="none";
JavaScript is not my strong point though and I have found that the previous web editor has a lot of repeat functions on the pages.
My idea is to create an external .js file and just call the function...it is for a rotating banner ad. The problem is the the function is called in the <Body> tag..this means that I have to change 100's of pages by adding the call function to the tag on every page.
Is there a way I can call the function as well as adding the function to the onLoad event.
I have tried adding "window.onload = rotateBanner;" to the beginning of my javaScript but it does not seem to work...what am I doing wrong
I have a series of dropdowns that allow the user to choose country, province and town respectively. The province dropdown is populated by an Ajax function when the user chooses their country, and the town dropdown is likewise populated by the user's selection in the province dropdown. This all works fine.
Of course, my client now wants to add a "major centres" dropdown between the province and town selection. This seemed straightforward to me, however in practice it's proving problematic. The "major centres" are drawn from the same dataset as the towns, however an extra flag is applied so that only records flagged as "main centre" appear.
Called separately , both the town dropdown and the main centre dropdown are populated. However, the problem comes in when the onChange event which is meant to update both dropdowns simultaneously fires. Watching the network behavior in Firefox, I see that calls to the ASP files which populate the town and major centre dropdowns DO happen, though only one of the calls actually returns values. I've checked this in IE7 also, and the same thing happens.
My function is called from the Province dropdown, like so:
what might cause only the one dataset to be returned via Ajax? Either the towns are populated or the major centres, depending on which order I call the two handleOnChange functions from my callOthers function. As I said, BOTH Ajax calls are made, however only the results of ONE are being used in my page. Could this problem be related to 2 Ajax calls being made too close together?
I can't seem to get the syntax correct to get this to work. I'm sure it is something simple.I want to call multiple functions inside my document.ready function.The first function gets called but not the second.
$(document).ready( function GetSuspectCollection() { $.ajax({[code].....
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 several form in my site, that validate on onsubmit.I call all the validation functions from a file call functions.js.Here is a sample of the code that is working:
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+)
