JavaScript - Body Onload Alternative?
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 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 The site i am building uses a large content slider as its main navigation. There is an absolutely positioned header on the page, and the slider sits underneath. This all works perfectly once i am linking (to named anchors) within the same page However when an external pages links to one of the anchors, the top of the slider content is hidden underneath the header - the user need to scroll down to get the content to start below the header. Long story short, I have used the following to force the browser to scroll to the top of the page when it loads: <script type="text/javascript"> window.onload = function(){ window.scrollTo(0,0); } </script> This doesnt load until everything else on the page has loaded though, is there a way to force the browser to scroll to the top BEFORE everything else loads? Or better yet not to scroll at all but to make sure the window is positioned at (0,0) automatically when it loads? Also, this doesnt seem to be working at all in IE Thanks in advance! hi guys, how can i get this code to load on body onload? without fading in and out? Code: <html> <head> <!-- For ease i'm just using a JQuery version hosted by JQuery- you can download any version and link to it locally --> <script src="http://code.jquery.com/jquery-latest.js"></script> <script> $(document).ready(function() { $("#responsecontainer").load("response.php"); var refreshId = setInterval(function() { $("#responsecontainer").load('response.php?randval='+ Math.random()); }, 9000); $.ajaxSetup({ cache: false }); }); </script> </head> <body> <div id="responsecontainer"> </div> </body> 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. 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 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()"> //more code here </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" /> 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 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.

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? Issue: I have a java script that bring up a simple password box, It works great in Chrome, Safari, firefox but I get a box in Internet explorer asking my customers to take another step to allow access. This is not good, Customers did not now what to do. Error: This website is using a scripted window to ask you for information. If you trust this website, click here to allow scripted windows Microsoft response: "Internet Explorer has blocked a website from using a small program (called a script) to display a separate window. Hackers sometimes use scripted windows to mimic legitimate windows, such as login screens, that appear on websites. If you trust the website and want to allow the scripted window, click the Information Bar, and then click Temporarily Allow Scripted Windows. To always allow scripted windows, check the Allow websites to prompt for information using scripted windows custom security setting." Objective: I now there is likely no way to by pass this, so i need a different solution. Possible a Form Box to be present on the site that when information is entered it passes the password to the javascript code to allow access?

The tutorial I am using, mentions that for tutorial example purposes they use document.write() however it suggests that I avoid using this as it will overwrite the whole HTML page. I know that I can use document.getElementById() for some things... however this begs my question: When do you use document.write(), when do you use document.getElementById() and is there also another method you use to change/write to the HTML Document using JavaScript? Otherwise, do you just use document.getElementById() quite a lot in JavaScript? Like I said, I'm very new to JavaScript, so it's all still very new to me. Cheers, Asher Hey everyone! I used to use iframes to load external content without resetting the parent page. After reading the disadvantage of iframes, I've been looking for alternatives. I Googled and found different solutions, however with a problem: what I found are all scripts that require Java, meaning my design would be rendered useless in a java-disabled browser. So is there a safe method I can use, one allowing me to have navigation tabs on a single page that loads content into a div/or any kind of alternative to an iframe (without resetting the page) ? Thanks in advance. Nat I need to detect the "name" of the constructor of an object. For example, myArray.constructor === Array is true, but I want something where that === 'Array' is true. I've heard of Object.constructor.name, but it's not widely compatible. Any ideas (preferably without involving regular expressions)? Thanks in advnce, Julian is there any alternative to document.write() which writes only in a specific part of document, does not overwrite whole document. and yeah, in this case the document.getElementById().innerHTML dosent work either, coz its in a loop, here's the code if you wanna see: Code: if (aa==1) { for (i=0;i<a.length;i++) { c = txt; b = a[i].childNodes[0].nodeValue; // a is already assigned someplace in a xml document. txt = (b==" T4 ")? "T4 <br />": ""; document.write(c); } } Note: in the above code, the code: Code: txt = (b==" T4 ")? "T4 <br />": ""; is same as (also can be written as ) the code : Code: if (b==" T4 ") { txt = "T4 <br />" ; } else { txt = "" ; } I'm working on code for my forums that will allow users to post text which can be moused over to display an image that will follow the cursor (provided the cursor is hovering above the specific text). The code works, but it obviously can't be used for more than one picture per page because getElementById finds the first div and always displays it onmouseover of any attempted mouseover text. The Javascript in <head> is Code: <script type="text/javascript"> // Pop up code begin function ShowPopup(hoveritem) { hp = document.getElementById("hoverpopup"); // Set popup to visible hp.style.visibility = "Visible"; } function HidePopup() { hp = document.getElementById("hoverpopup"); hp.style.visibility = "Hidden"; } // Follow mouse script begin var divName = 'hoverpopup'; // div that is to follow the mouse // (must be position:absolute) var offX = 5; // X offset from mouse position var offY = 5; // Y offset from mouse position function mouseX(evt) {if (!evt) evt = window.event; if (evt.pageX) return evt.pageX; else if (evt.clientX)return evt.clientX + (document.documentElement.scrollLeft ? document.documentElement.scrollLeft : document.body.scrollLeft); else return 0;} function mouseY(evt) {if (!evt) evt = window.event; if (evt.pageY) return evt.pageY; else if (evt.clientY)return evt.clientY + (document.documentElement.scrollTop ? document.documentElement.scrollTop : document.body.scrollTop); else return 0;} function follow(evt) {if (document.getElementById) {var obj = document.getElementById(divName).style; obj.left = (parseInt(mouseX(evt))+offX) + 'px'; obj.top = (parseInt(mouseY(evt))+offY) + 'px';}} document.onmousemove = follow; </script> So the display code is Code: <a id="hoverover" style="cursor:default;" onMouseOver="ShowPopup(this);" onMouseOut="HidePopup();">text here</a> <div id="hoverpopup" style="visibility:hidden; position:absolute;"><img src="url here"></div> I just want to be able to have more than one instance on each page and still be able to declare the image url in the body and not within the javascript. Hey guys. So right now I'm able to execute javascript code on my website without the use of <script> tags. Example: <body onload=alert("cool");></body> What I want to be able to do is insert an external javascript file located at another website using JavaScript code (not script tags). How can this be done? Thanks |
