Thanks 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 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" />
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!! 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. 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 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???? 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 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? Good morning guys. I am new to Javascript and am trying to add some functionality to a website but have come across a problem when trying to utilise two seperate Javascript onloads events. I have a text scroller to display the latest news and I also have a javascript lightbox gallery. Both of these events work perfectly on their own but when I try to include both on one page only one of the events is executed. My code is displayed below: Code: <script type="text/javascript" src="js/prototype.js"></script>
<script type="text/javascript" src="js/scriptaculous.js?load=effects,builder"></script>
<script type="text/javascript" src="js/lightbox.js"></script>
<script type="text/javascript" src="js/jquery-1.2.6.pack.js"></script>
<script type="text/javascript" src="js/jquery.li-scroller.1.0.js"></script>
<script type="text/javascript">
$(function(){
$("ul#news-scroller").liScroll({travelocity: 0.04});
});
</script>
</head>
<body onload="clickMenu('gallery'); initLightbox()">
If anyone could tell me where my mistake is I would be so grateful. I know it is probably a really obvious mistake but being new to this I am unsure where to start looking. Thanks in advance! Mack Hi, thanks for reading, I have to admit, I'm a noob, but what my code does drives me nuts, eternal thanks to whoever tries to help me out! In short my problem is that document.body.scrollHeight does not give me the correct pagesize combined with the viewport. I just want the parts of the page to be as long as the (in the original dynamicly entered) text in the middle. Imho pageheight = (document.body.scrollHeight+viewportheight); should give me the correct height of the page, but does not, why? It works and it is close, but not completely, I tried stuff like document.body.offsetHeight etc., but my guess is I miss facturing in a parameter, but I have not the slightest clue which... Here the page: http://buchenbergschule.de/ruh/depre...ode/test7.html Here the JS Code: Code: <script type="text/javascript">
<!--
var viewportwidth;
var viewportheight;
var pageheight;
if (typeof window.innerWidth != 'undefined')
{
viewportwidth = window.innerWidth,
viewportheight = window.innerHeight
}
else if (typeof document.documentElement != 'undefined'
&& typeof document.documentElement.clientWidth !=
'undefined' && document.documentElement.clientWidth != 0)
{
viewportwidth = document.documentElement.clientWidth,
viewportheight = document.documentElement.clientHeight
}
else
{
viewportwidth = document.getElementsByTagName('body')[0].clientWidth,
viewportheight = document.getElementsByTagName('body')[0].clientHeight
}
pageheight = (document.body.scrollHeight+viewportheight);
document.write('<style type=text/css> div#linksaussen');
document.write('{width:468px; height:'+(pageheight-896)+'px; position:absolute; top:896px; left:'+(((viewportwidth-948)*0.5084)-468)+'px; background-image:url(./images/back_links.png);}');
document.write('div#linksaussen1 {width:468px; height:897px; position:absolute; top:0px; left:'+(((viewportwidth-948)*0.5084)-468)+'px; background-image:url(./images/testlinks.png);}');
document.write('div#mitte {width:948px; height:'+pageheight+'px; position:absolute; top:0px; left:'+((viewportwidth-948)*0.5084)+'px; background-color:#FF0000;}');

Again please forgive my noobishness, my bad english and thanks again for any hint! Hi, I'm looking to create a box that shows to IE6 users or lower, to tell them that my site does not render properly in the IE6 browser and that they should therefore upgrade to a newer version or alternative browser. Basically I would put whatever the code to show the box into these tags: Code: <!--[if lte IE 6]> INSERT HERE <![endif]--> to enable it to only appear to IE6 or below users. Preferably when this box appeared, it would be nice if it could fade the page behind it. Does anyone have a script for this or know of a tutorial I could use? The box would also need buttons at the bottom that said "Ok, upgrade me" (this would load another window with links to alternative browsers) or "No thanks" (or "Close") Thanks in advance. Am I saying the onload event wrong or something? PHP Code: <input type="button" value="Mouse" onload="popup_show('popup', 'popup_drag', 'popup_exit', 'mouse', -10, -10);" /> Other events like onmouseover and onClick work Hi all I would like the img src to be populated after page load I'm not sure this is doing what I would like it to do. I have done this. (tag shortened for post) Code: <img src="" id="testImg2" onload="(this.src='images/USA.jpg')"/> Is this populating the img src after page load or when the img tag is loaded? LT I have this code: Code: <script type="text/javascript" src="http://s7.addthis.com/js/250/addthis_widget.js#username=xa-4c7b22470e521876"></script> I want this JavaScript code above to be executed when all My page finished loading (maybe by using JavaScript onload) So how can I do that? All, I have a function that loads with the onload command. Is there a subsitute for this? I have an AJAX call so sometimes content gets loaded on the page without the onload event being triggered but I need it to go to this function when the AJAX displays the new content. Any ideas? If it makes a difference, the AJAX is calling a PHP page. Thanks in advance. Hi, I got some JavaScript code from the net to resize DIV's depending on the window-size. It works perfectly in FF, but it won't work in IE. Code: function Resize(){
var winW = 630, winH = 460;
if (parseInt(navigator.appVersion)>3) {
if (navigator.appName=="Netscape") {
winW = window.innerWidth-30;
winH = window.innerHeight-200;
}
if (navigator.appName.indexOf("Microsoft")!=-1) {
winW = document.body.offsetWidth-30;
winH = document.body.offsetHeight-200;
}
}
var topHeight = document.getElementById('top').offsetHeight;
var setHeight = document.getElementById('settings').offsetHeight;
var headersHeight = document.getElementById('headers').offsetHeight;
var leftWidth = document.getElementById('left_column').offsetWidth;
document.getElementById('container').style.width=winW+"px";
document.getElementById('container').style.height=(winH-topHeight-setHeight)+"px";
document.getElementById('headers').style.width=(winW-leftWidth)+"px";
document.getElementById('data').style.width=(winW-leftWidth)+"px";
document.getElementById('data').style.height=(winH-topHeight-setHeight-headersHeight)+"px";
}
I've been working on this for some days. I would appreciate any help I can get. Erik Hi all, I have some javascript that when a link is clicked hides the div and when it is clicked again shows the div... what I want to do is reverse that, so it is intially hidden. I have tried changing the display none to different parts but it always shows on load: Code: function toggleDiv (divid) {
if (document.getElementById (divid).style.display == 'none') {
document.getElementById (divid).style.display = 'block';
} else {
document.getElementById (divid).style.display = 'none';
}
}
Code: <a href="javascript:;" class="showmorelink" onmousedown="toggleDiv('checks');">Safeguarding</a>
Can anyone advise? Many thanks, Greens85 |
