JavaScript - Call Onload Function
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. Similar TutorialsI 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. 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'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 hoping I just need to be pointed in the right direction with this. I have Page1. When Page1 body onloads it uses Ajax to call PartA Within PartA I have a message board so members can write messages which will be sent to my database in PartA[1] and immediately posted for view on to PartA[2]. As I want to have my request to the server updating regularly I want to have PartA[2] on a timed loop to refresh - I do not need the content of PartA[1] to refresh. So the order of events would look like this: Page1 | onload call | v PartA / \ V V PartA[1] PartA[2] (loads once) (constantly refreshes) What I am not sure about is that I have <body> and <head> attributes in Page1 only. I have already used my body onload to call PartA (and can't use it to call PartA[2] before PartA has loaded anyway). I do not want the user to have to click a button or do anything to call up PartA[2]. So my question is how would I get PartA[2] to automatically load within PartA? I hope I have made this clear, but if I haven't let me know and I will try again. i keep getting error Call to undefined function codeandurl() below is my code PHP Code: <?php $value= strip_tags(get_field('link',$post)); $resultid=get_field('resultid',$post); codeandurl($resultid,$value); ?> <div id="result"></div> <script type="text/javascript"> function codeandurl(resultid,url){ $( "#result" ).text(resultid); $( "#result" ).dialog({ modal: true, buttons: { Ok: function() { $( this ).dialog( "close" ); } } }); window.open(url); return false; } </script> <p> <script type="text/javascript">// <![CDATA[ var metrics = { "mm" : 1, "cm" : 10, "m" : 1000, "inch" : 25.4, "foot" : 304.8 }; function convert(num, dec){ var val = document.getElementById("fromVal").value; if(isNaN(val)){ return } function roundNumber(num, dec) { var result = Math.round( Math.round( num * Math.pow( 10, dec + 1 ) ) / Math.pow( 10, 1 ) ) / Math.pow(10,dec); return result; } document.getElementById("toVal").value = val * metrics[document.getElementById("fromSystem").value]/ metrics[document.getElementById("toSystem").value]; } var interval = null; function watchChanges(){ interval == null ? setInterval("convert()", 500) : clearInterval(interval); } // ]]></script> </p> <table> <tbody> <tr> <td><input id="fromVal" style="width: 100px;" onfocus="watchChanges()" onblur="watchChanges()" type="text" /><select id="fromSystem" onchange="convert()"> <option value="mm">millimeters</option> <option selected="selected" value="cm">centimeters</option> <option value="m">meters</option> <option value="foot">feet</option> <option value="inch">inches</option> </select></td> </tr> <tr> <td colspan="1" align="center">=</td> </tr> <tr> <td><input id="toVal" style="width: 100px;" type="text" disabled="disabled" /><select id="toSystem" onchange="convert()"> <option value="mm">millimeters</option> <option value="cm">centimeters</option> <option value="m">meters</option> <option selected="selected" value="foot">feet</option> <option value="inch">inches</option> </select></td> 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');

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???? Code: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

This is a very basic version of what I am trying to do. I have a dynamic list which is set in a table. When clicked, a function is run to set up a new list.. The reason I explain that, is that I need to keep it dynamic. Now for the problem: When I run this page, I have the button made right away, then when clicked it creates the new button. The new button should also run the function to create the new button again, but when I click it, I only receive "error on page". I don't know if there is a better way to go about this, but as for this route, I am stuck. Any help is greatly appreciated! -Shane I'm trying to "progressively enhance" one of my surveys using javascript. Basically, I have rating scales that make use of radio buttons as each point on the scale. Each radio button occupies its own cell in a table. I wrote some functions that will highlight cells on mouseover in a color corresponding to its position on the scale (e.g. the lowest point is red, the midpoint is yellow, the highest point is green). When a radio button is clicked, the background of the button's cell and preceding cells in the same row will be colored accordingly. The functions are working well in FireFox and Chrome (I just have to add a few lines using the addEvent function to make it compatible with IE). The effect looks a lot nicer when I add a function that makes the visibility of the radio buttons hidden. However, I want to make sure that there is a fallback option in case the functions that color the cells don't work for whatever reason. I would not want the radio buttons hidden in this case. Is there a method whereby I can call the "hideRadiobuttons" function only if the other functions are successfully executed? 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 Hello 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 Hello, if in a webpage is included a javascript file (for example code.js) can I from my browser call a function contained in code.js and will it works correctly? I'm not meaning that the function is called in the page with or without a link to click, but it is only in code.js! Thank you! Hello. Started my massive JavaScript career just yesterday and the forums I frequent still lack a proper BB-code hide-tag, so I figured I'd try make it in JavaScript, since HTML is allowed on there. This is what I did: Code: <script type="text/javascript">
function show() {
document.getElementById('silHideTextTag').innerHTML='Hidden text!!';
document.getElementById('silHideTextBtn').value='Hide';
document.getElementById('silHideTextBtn').onclick='hide()';
}
function hide() {
document.getElementById('silHideTextTag').innerHTML=' ';
document.getElementById('silHideTextBtn').value='Show';
document.getElementById('silHideTextBtn').onclick='show()';
}
</script>
<input type='button' id='silHideTextBtn' onclick='show()' value='Show'/>
<div id='silHideTextTag'> </div>
The button labelled "Show" appears fine, when I click it it becomes "Hide" and the text "Hidden text!!" is shown. However, when I click the button again, nothing happens at all. I don't quite understand where the problem is. Thanks in advance for any clues. Best regards, Zyl My problem is that I am trying to call an function within an SWF. Now, I already know how to setup my SWF and that isn't the problem. The problem is that when I try to call the function using Javascript, I am told that the function doesn't exist. I'll show you the code right here. Code: function AudioPlayerEmbed( e )
{
if ( e.success )
{
e.ref.LoadAudio( 'http://therevolve.com/upload/userfiles/Music/Alec_Smith1.mp3' );
}
}
swfobject.embedSWF("player/MP3Player.swf", "flash", "300", "90", "9.0.0", "player/expressInstall.swf", null, null, null, AudioPlayerEmbed );
HOWEVER, when I put some alert before the call, it happens to work. What is going on? Code: function AudioPlayerEmbed( e )
{
alert("A");
if ( e.success )
{
e.ref.LoadAudio( 'http://therevolve.com/upload/userfiles/Music/Alec_Smith1.mp3' );
}
}
swfobject.embedSWF("player/MP3Player.swf", "flash", "300", "90", "9.0.0", "player/expressInstall.swf", null, null, null, AudioPlayerEmbed );
Here is a live example. Any help would be appreciated. If you need more information, I can provide it. I'm trying to implement this 'ajax' script, however i'm getting the following error: function expected line 25. And I'm not the only person who is getting this error message :S How can the code be altered so it will work? Also the script isn't executed when I change onclick in onload :S How come and how can I change it so that it will be executed on launch? http://chriscook.me/web-development/...icking-a-link/ HI I have tow page and the first page open a new window with javascript(by using window.open).Now I want to call a javascript function that is in the first page from the second page and for that i use parent.function_name but it doesn't work.How can do so? thanks <frameset rows="30%,70%> <frame src="page1.html" name="name1" frameborder="0"></frame> <frame src="page2.html" name="name2" frameborder="0"></frame> </frameset> in above code I used page1.html & page2.html as frame. Both include same javascript file having two function name fun1() & fun2(). as both are separate frame both have there own copy function page1.html fun1() fun2() page2.html fun1() fun2() I call fun2() from page2.html and inside that function I want to call page1.html's fun1(). fun1() in page1.html and fun1() in page2.html both return different result because of there global variables. Is there any way to call fun1()-page1.html from the fun2()-page2.html? I am trying to make an onblur that calls a function and passes it some text, for example: onblur = "function("Hello")" however this wont work as it is not even calling the function. I have tried all the different encapsulation tags I can think of but still no luck is there any way of doing it or can I assign the text to a variable and call the function in the onblur? Thanks.:confused: |
