JavaScript - How To Onload A Function If No Access To Body Tag
Hey guys I am having trouble loading a drop down menu list script that I got from Dynamic Drive.
Here's the original test page. (Works Fine) <html> <head> <script language="javascript" src="http://www.modbargains.com/images/Javascript/ChainSel/chainedmenu.js"> </script> <script language="javascript" src="http://www.modbargains.com/images/Javascript/ChainSel/MBVehicleChainSelect.js"></script> </head> <body onLoad="initListGroup('Vehicles', document.listmenu0.firstlevel, document.listmenu0.secondlevel, document.listmenu0.thirdlevel, 'savestate')"> <form name="listmenu0"> <table align="center"> <tr> <td><select name="firstlevel" style="width:160px;"></select></td> </tr> <tr> <td><select name="secondlevel" style="width:160px;"></select></td> </tr> <tr> <td><select name="thirdlevel" style="width:160px;"></select></td> </tr> <tr> <td><input type="button" value="Go" onClick="goListGroup(document.listmenu0.firstlevel, document.listmenu0.secondlevel, document.listmenu0.thirdlevel)"> <input type="button" value="Reset" onClick="resetListGroup('Vehicles')"> </tr> </table> </form> </body> </html> HOWEVER! The site I am working on (which is on a different server) does not allow me to alternate the body tag. Is there an alternative way of doing a body onLoad without actually alternating the body tag? I read that you could do a function onload using javascript, so I tried using this: <script language="javascript" > window.onload = initListGroup('Vehicles', document.listmenu0.firstlevel, document.listmenu0.secondlevel, document.listmenu0.thirdlevel, 'savestate'); </script> I am not sure if the function is correct but it does not work. Any ideas how I can make this work???? Similar TutorialsHello Can anyone help with the following problem On the following page http://www.stroudskittles.co.uk/signingon.html I have a Body onload event (to load the chained Menu) and a windows.onload event (to load the IFrame Ticker) If I open the page in Internet explorer both scripts function; however in Firefox I'm having problems. The Chained Menu works, however the IFrame Ticker does not display. Both events ahave ben placed on the boady tag. Can anyone advise how I can get both to display in Firefox Can anyone hi guys, how can i get this code to load on body onload? without fading in and out? Code: <html>

Thanks I found a little chat script online and I wanted to check it out. When I integrated it into a page I created, for some reason this will not work correctly <body onload="setInterval('chat.update()', 1000)"> I tested it with two different browswers open Lets say on two different browser windows you have user1 and user2 if user1 types 'Hello' it will not show up on user2 window but if user2 types 'Hi' then on user2 window it will say user1 says Hello user2 says Hi so basically for user1 to see what user2 has wrote, user1 has to type something first and send it to see what user2 said. hope you understand, if you would like I could post up the code. i cannot understand, am i making the same mistake each time but my <body onload="startChecking()"> does not want to load again?? here my full code: Code: <head>
<script language="JavaScript" type="text/javascript">
var sendReq;
var receiveReq;
var lastmessage = 0;
var mTimer;
function startChecking()
{
receiveReq = new XMLHttpRequest();
console.log("1234");
getNewMessage();
}
function getNewMessage()
{
if (receiveReq.readyState == 4 || receiveReq.readyState == 0)
{
console.log(receiveReq.readyState);
}
mTimer = setTimeout('getNewMessage();',30000);
}
</script>
</head>
<body onload="startChecking()">

</body>
i just want the console.logs to execute then i will continue with the rest of my code... please help? thank you I am a novice with Javascript and need help. The homepage of the website I am developing includes a simple javascript slideshow. The code for the script came from a different site that allowed code sharing. It functions wonderfully once loaded. However, in Internet Explorer, I must control-click to allow for the script to run. This wouldn't be a huge problem, but it is an inconvenience to visitors of the site. Since the website is for a public high school, the district computers have a high security setting. Therefore, anyone trying to access the site from a school computer (the main clientele) will have to control-click and allow access everytime they wish to visit the site. Not ideal. I know my problem is that I am using <body onload="runSlideShow">. I have tried including the defer attribute, but that did not work. Is there any other way I can write the code to not cause viewers to control-click everytime the page is loaded? Thanks tons! EDIT---- When opened in IE 7, there is a bar that warns againsts scripts and activex. I understand that I can lower my personal security setting, but I don't have the authority to do so for district PCs. Once a user clicks to allow the script the slideshow begins automatically. So, how can I write the code so that the warning bar does not show up? ---- Here's the bit of code that is applicable. Code:
<script language="JavaScript">
var slideShowSpeed = 4000;
var crossFadeDuration = 4;
var Pic = new Array();
Pic[0] = 'field.jpg'
Pic[1] = 'mural3.jpg'
Pic[2] = 'cheer1.jpg'
Pic[3] = 'Nuncrackers.jpg'
Pic[4] = 'soccer4.jpg'
Pic[5] = 'radio4.jpg'
var t;
var j = 0;
var p = Pic.length;
var preLoad = new Array();
for (i = 0; i < p; i++) {
preLoad[i] = new Image();
preLoad[i].src = Pic[i];
}
function runSlideShow() {
if (document.all) {
document.images.SlideShow.style.filter="blendTrans(duration=2)";
document.images.SlideShow.style.filter="blendTrans(duration=crossFadeDuration)";
document.images.SlideShow.filters.blendTrans.Apply();
}
document.images.SlideShow.src = preLoad[j].src;
if (document.all) {
document.images.SlideShow.filters.blendTrans.Play();
}
j = j + 1;
if (j > (p - 1)) j = 0;
t = setTimeout('runSlideShow()', slideShowSpeed);
}
</script>
<body onload="runSlideShow()">
<img src="field.jpg" name='SlideShow' width="814" height="300" />
Hi, Is there any alternative to the ' body onload="" ' function? I have on the page several scripts running and one is blocking the others because of the body onload function. It is working if I change that to body onfocus but it is loading the content all over when the user gets back to the page. Any ideas how can I avoid this? I can't apply onload to some element, onfocus is not working and this code also does not suite me: Code: <script type="text/javascript> function(); </script> Thanks in any case! Batric What I mean is that my <body> tag currently is like this: Code: <body class="page-course"> I would like to insert a pop-up contact form which requires the body tag to be like this: Code: <body onload="javascript:fg_hideform('fg_formContainer','fg_backgroundpopup');">
Not quite sure how to merge these - indeed can I merge them? Perhaps better to make the body class (top example) execute elsewhere? THANKS!! Hi guys. I have a quick question. What's the code for having a link with the id "autoid" clicked when the body of my html code loads? Thanks, Alex hi all im trying to hide a div on page load, ive used this. Code: <script type="text/javascript">
function hideDiv(){
document.getElementById('sidebar').style.display = "none";
}
hideDiv()
</script>
and this in the body tag Code: <body onload="javascript:hideDiv()"> it works fine hiding the div named sidebar, problem comes when i try to then use an Onclick event to show the hidden div, it just wont show. can this be done? please help if you can this work has to be in soon If I use a window opener to open a new window, is there a way to detect that the new window is finished loading before carrying out some other directive in the opener window? Can I access the remote window's onload event from the opener window? I need to know that the website has loaded before moving to the next page. something like: remoteWindow.onload = goToPage(url); Is this even possible? Hi, I have a form that I am submitting using JQuery, if I copy and paste the form into my main page, everything works fine. If I try to call the form in a separate page to onload none of the buttons work. Is there away around this?

I know I have buttons doing the same function,there is an ease of use reason for it. I can put everything on my main page if necessary, but it wouldn't really be doing exactly what I want it to do. Hi, I am building a navbar using suckerfish. The company that I am using to host the site places onload="page_init()" in the <body> tag automatically. This kills the suckerfish js. Is there a way to remove this onload="page_init()" using a js, or will it just kill that js also? I have a popup window that calls a texteditor. I want the texteditor to show the inner HTML of the parent doucument by div id. When I call the function through a submit (in child window) it workks great, but I want innerHTML to be added when child page loads. I have tried calling function in body onLoad=getparent; tries adding it to inner script where it calls the editor , again onLoad=getparent; Tried with and without () i.e onLoad=getparent(); Child window code: [code] <html> <head> <title>Mangae Content</title> <script type="text/javascript" src="/ckeditor/ckeditor.js"></script> <script language="javascript"> function getparent() { var TextToPass = window.opener.document.getElementById('missionStatement'); var TextToEdit = TextToPass.innerHTML; document.getElementById('editor1').value=TextToEdit; } </script> </head> <body> <form method="post" name="editedcontent"> <p> My Editor:<br /> <textarea name="editor1" id="editor1"></textarea> <script type="text/javascript"> onload=getparent; CKEDITOR.replace( 'editor1' ); </script> </p> <p> <input type="submit" onClick="getparent();"/> </p> </form> </body> </html> [code] When I use the submit button it works fine. Captures parent window HTML and loads it into ckeditor, How do I get it to load without using the submit button??? Any help would be greatly appreciated. I'm trying to get a select box to populate onload but can't get it to go. It works fine onchange. This populates the city select box from my db depending on what state is selected. Here are the functions: Code: function handleOnChange(dd1)
{
var idx = dd1.selectedIndex;
var val = dd1[idx].text;
var par = document.forms["cbcheckedadminForm", "adminForm"];
var parelmts = par.elements;
var cb_citysel = parelmts["cb_city"];
var state = val;
var directory = ""+document.location;
directory = directory.substr(0, directory.lastIndexOf('/'));
Http.get({
url: "./components/com_helloworld/js/regvalues/" + state + ".php",
callback: fillcb_city,
cache: Http.Cache.Get
}, [cb_citysel]);
}
function fillcb_city(xmlreply, cb_cityelmt)
{
if (xmlreply.status == Http.Status.OK)
{
var cb_cityresponse = xmlreply.responseText;
var cb_cityar = cb_cityresponse.split("|");
cb_cityelmt.length = 1;
cb_cityelmt.length = cb_cityar.length;
for (o=1; o < cb_cityar.length; o++)
{
cb_cityelmt[o].text = cb_cityar[o];
}
}
else
{
alert("Cannot handle the Ajax call.");
}
}
And here's how I'm trying to do the onload: Code: function addLoadEvent(func) {
var oldonload = window.onload;
if (typeof window.onload != 'function') {
window.onload = func;
} else {
window.onload = function() {
if (oldonload) {
oldonload();
}
func();
}
}
}
addLoadEvent(function() {
ajaxFunction(document.getElementById('country').value);
});
addLoadEvent(function() {
setupDependencies('cbcheckedadminForm', 'adminForm', 'locationsearch');
});
addLoadEvent(function() {
handleOnChange(dd1);
});
addLoadEvent(function() {
fillcb_city(xmlreply, cb_cityelmt);
});
I've tried variations of handleOnChange(cb_state), handleOnChange(document.getElementById('cb_state'), handleOnChange(ydntuwrkupceofcrp), I've tried chaining the 2 functions together, but nothing I do seems to get this to work. What am I missing here? Hi I am new to javascript and designing websites as a whole. I have been playing around with a drag and drop java script from this site: http://www.redips.net/javascript/dra...table-content/ A switch content setting is currently available to check in a checklist: <input name="drop_option" type="radio" class="checkbox" title="Switch content" onclick="set_drop_option(this)" value="switch"/> I wan it to run without any checklist or button whatsoever just from the page load. I am not sure how I would do this. Any suggestions? Thank you Jonathan I am relatively new to JavaScript so am still learning. I have a page I would like to call a function when it loads but not sure how to do this. The function is http://tickettransaction.com/?bid=20...ults&venid=101 and should function similar to this page when loads http://paviliondallas.com/ I could get that with html but not sure how to auto load to render ths list from the provided plugin. Another example is http://www.justbuytickets.com/Venues...FcY32godDU-hzw Any help would be appreciated. Thanks in advance. I don't get to use javascript as much as I would like, but I am having a problem with a page so I stripped out all the extras and got down to just the part I am having a problem with and I think this should fill the div with the id testingdiv when the page loads but it doesn't. Any help would be appreciated. Code: <script type="text/javascript">
function getClientList(listtype) {
document.getElementById('testingdiv').innerHTML = listtype;
}
window.onload = getClientList('own');
</script>

<body>
<div id="div1" onclick="addHeight(this.id)" style="width: 200px; height: 20px; background-color: yellow;">Increase Height</div>
</body>
</html>
How can I still use the parameter "openAccordionID" in the blue-highlighted part? I tried, but it failed. The only way I know to make a script automatically run on the page is by using the "onLoad" property of the HTML body tag. However, I'm working with a template that serves the same header and footer for every page on my site, and this JavaScript is only needed on a single page. I therefore don't really want to edit the body tag with a function call that won't be needed in most cases. To avoid doing this, is there any other way to make a piece of JavaScript run without input from the user? All I want to do is autofocus on a form field. Thanks for any advice. I have the following javascript function: [ function addNewWindowEvent(evType, fn) { if (window.addEventListener) { this.addEventListener("load", fn, false); return true; } else if (window.attachEvent) { var onload = "onload" this.attachEvent(onload, fn); return true; } else { return false; } } ] which is giving me a an exception every time a page on our site loads. The actual exception in firefox is this: uncaught exception: [Exception... "Could not convert JavaScript argument" nsresult: "0x80570009 (NS_ERROR_XPC_BAD_CONVERT_JS)" location: "JS frame :: https://cms-dev.stchas.edu/global/js/hdvscripts.js :: addNewWindowEvent :: line 5" data: no] and I'm not sure exactly what it's complaining about. I'm relatively new to javascript so diagnosing and fixing this problem has me quite puzzled, and so far I have been unable to find anything helpful when I try and google for information on this. I would appreciate any help or suggestions. Thanks. henryv |
