JavaScript - Dynamically Replacing Onmouseover
Hi,
I am quite new to JS and is currently building a website with a little of JS Function. Ok, so I have a Page tat consists of 10 images. Each images when on mouse over, will display a larger version on the images, using JS(onmouseover). Then, I will have a next button that will replace all the images, using Ajax, which means my page will not be reloaded. The problem comes here when I have to replace all the onmouseover effect. I can replace all the thumbnails without problem, but the onmouseover I have problem replacing. Is there anyway that I can dynamically replace all the onmouseover? Any help will be appreciated. Thanks Similar TutorialsSo I have been struggling with a Javascript issues for a couple of days now and can't find an answer anywhere online that has helped. I have a javascript loop that is looping through all of my <dfn> html tags. These tags are used to show a glossary term on my page. When the user mouses over the term it shows a popup with the term name and the definition. Here is my javascript function: Code: function definitionRollover(){
var j;
var dfns = document.getElementsByTagName('dfn')
for (j=0; j<dfns.length;j++){
var term = dfns[j].innerHTML.charAt(0).toUpperCase() + dfns[j].innerHTML.slice(1);
var definitionArray = new Array(term, dfns[j].title);
dfns[j].onmouseover = function(){stm(definitionArray,Style[0])}
dfns[j].onmouseout = function(){htm();};
}
}
As you can see I am adding a onmouseover event to these <dfn> tags which calls another function (stm) with the definition and term being held in the definitionArray. This works great until I have multiple terms on a page. When I have multiple terms it only shows the last terms definition for all terms. My question is how I can get it to work for all terms. I know that throughout the loop the definitionArray is holding the correct info at the correct time but for some reason it only shows the last one. I hope that this makes sense and if anyone could give me any tips or leads it would be very much appreciated. hi, I am curious about the use of appendChild() here... I have a solution that does what I want it to do, like this: Code: var sidebarEntry = createSidebarEntry(poly, html); sidebar.appendChild(sidebarEntry); sidebar.replaceChild((sidebarEntry),sidebar.firstChild); but it seems to be going the long way around. Not that it matters much (I guess), but all I want to do is to add an item to the sidebar and when a new item is added, remove the existing one. I tried just using relaceChild() on its own, but the code seems to need something to be replace... Is the above the best way to do it? Or is it possible to set the child to some dummy position like null to begin with, so that the code is not constantly reloading and replacing items (which is what I understand is going on now)? here's the page I'm working on, if you want to see the rest of the code. I appreciate any thoughts. Is it possible, when a page is reloaded, to replace a link to a javascript in the head with a link to a different script?
Hi, I know how to replace all the + signs in a url string by spaces, like this: newstring=oldstring.replace(/[+]/g," "); but how do I replace a substring by a comma easily? This doesn't do it: newstring=oldstring.replace(/[&menuitems]/,","); Thanks in advance for any help. I have the following code that works fine: Code 1 Code: <script type="text/javascript">
AJS.AEV(window, 'load', function() {
GB_show("Special Presentation", "http://www.site.net/temp/images/ads/special.jpg", 352, 600);
});
</script>
I also have the following code that works fine: Code 2 Code: function DoTheCookieStuff()
{
visited=getCookie('visited');
if (visited==null)
{
setCookie('visited','yes',365)
MyWindow=window.open('http://www.site.com','MyWindow','toolbar=yes,location=yes,directories=no,status=yes,menubar=yes,scrollbars=yes,resizable=yes,width=640,height=480,left=1,top=1');
}
}
However, I want to replace the blue code in the Code 2 immediately above that opens the window with the red code in the Code 1 section that opens the GreyBox window. I tried the following but it's just not working: Code: function DoTheCookieStuff()
{
visited=getCookie('visited');
if (visited==null)
{
setCookie('visited','yes',365)
AJS.AEV(window, 'load', function() {
GB_show("Special Presentation", "http://www.site.net/temp/images/ads/special.jpg", 352, 600);
});
}
}
Thank you. Hey guys... Basically I need a function that will remove numerous elements from a page based on their class. I then also need a function to bring those elements back afterwards. If anyone is wondering, I'm trying to add buttons to remove/add images. Thanks! I'm sorry this is simple, but: Code: function printInput(f){
var ifr = window.frames['printFrame'];
var v1=readCookie('lesson');
if (v1==1){v2='WORKNOTEPAD1'}
if (v1==2){v2='WORKNOTEPAD2'}
if (ifr){
ifr.document.getElementById('content').innerHTML=f. v2 .value.replace(/\n/g,'<br />');
ifr.focus();
ifr.print();
}
else { something }
}
In this line: Code: ifr.document.getElementById('content').innerHTML=f. v2 .value.replace(/\n/g,'<br />');
How can I make it stop erroring and act as if the "v2" were, say, "WORKNOTEPAD2"? If the line contains the string it all works fine. It must be so simple... I'm a bit of a Javascript noob, so please bear with me! I'm trying to create a piece of code that will check a webpage and replace any instances of a specific line of HTML with another line of HTML. The code I have so far doesn't work, but I have a feeling that's down to my awful Javascript skills! For example, in the following code I'd want to replace all instances of <li><a href="index.pdf">Index</a></li> with <li><a href="contents.pdf">Contents</a></li> Code: <div id="downloads">
<p>Please click on your downloads below:</p>
<ul>
<li><a href="index.pdf">Index</a></li>
<li><a href="chapter1.pdf">Chapter 1</a></li>
<li><a href="chapter2.pdf">Chapter 2</a></li>
<li><a href="chapter3.pdf">Chapter 3</a></li>
<li><a href="credits.pdf">Credits</a></li>
</ul>
</div>
The Javascript I have so far is: Code: <script type="text/javascript">
var aEls = document.getElementsByTagName('a');
for (var i = 0, aEl; aEl = aEls[i]; i++) {
aEl.href = aEl.href.replace('index.pdf','contents.pdf');
}
Obviously this is meant to just replaces the a href elements, but I got a bit stuck after this! Any pointers would be much appriciated. I have 16 links on a page, when each link is clicked, I need to change text that is on the page. This is Page 1 link 1 This Is Page 1 link 2 This is Page 2 ... link 16 This is Page 16 How can I do this? Excuse my ignorance, this is my first JS project Hey folks. I currently have a PTZ camera that is taking screenshots every minute (or so) and sending a copy of that image (overwriting the previous one) to my website. Basically, the visitors to the website will be greeted with a live screenshot. The problem is if the visitor hits the website at just the right time, the screenshot won't be loaded completely while the 2nd most screenshot is being overwritten... creating an empty image load (the dreaded red X). What I am looking to do with Javascript is to be able to load a generic image in the scenario in which no image loads. Is that possible? I tried doing something like the following and onload-ing it, but it wouldn't work. Any help would be appreciated. Thanks! Code: <script type="text/javascript">
<!--
function replaceSrc() {
var images = document.getElementsByTagName('img');
for(var i = 0; i < images.length; i++) {
var img = images[i];
if(img.src.length == 0) {
img.src = 'images/garbage.gif';
}
}
}

Ok, i have a javascript that creates a table then appends it to an empty div. This works fine in FF, however it fails to work in IE8. [edit] I have decided to post the entire code since I wasn't having any luck getting any suggestions. Maybe now someone can help me out. Code: function createTable() {
var machine = document.Catalog.machine.value;
var dSearch = document.Catalog.dSearch.value;
var section = document.Catalog.section.value;
var x = xmlDoc.getElementsByTagName('record');
var y = xmlDoc.getElementsByTagName('data');
var newEl = document.createElement('TABLE');
newEl.className = 'resultsTab';
var tmp = document.createElement('TBODY');
newEl.appendChild(tmp);
var row = document.createElement('TR');
var n = 1;
var headings = new Array("Col1", "Col2", "Col3", "Col4", "Col5");
var dcount = 0;
//for (t=0;t<10;t++) {
for (t=0;t<y[0].childNodes.length;t++) {
if (y[0].childNodes[t].tagName == "record") { // it is required for FF to work properly
dcount++;
}
}
if (document.Catalog.thumbImg[0].checked) {
var container = document.createElement('TH');
var theData = document.createTextNode("Pic");
container.className = "topline1";
container.appendChild(theData);
row.appendChild(container);
}
for (h=0;h<headings.length;h++) {
var container = document.createElement('TH');
var theData = document.createTextNode(headings[h]);
container.className = 'topline' + n;
container.appendChild(theData);
row.appendChild(container);
n++;
}
tmp.appendChild(row);
switch (searchtype) {
case 1:
var objRegex = new RegExp(machine);
break;
case 2:
var objRegex = new RegExp(section, "i");
break;
case 3:
var objRegex = new RegExp(dSearch, "i");
break;
default:
document.getElementById("replaceTxt").innerHTML = "<p>There was an error processing your request.</p>";
}
var rowColor = 1;
var noResult = "false";
for (i=0;i<dcount;i++) {
var row = document.createElement('TR');
var searcharr = new Array();
for (j=0;j<x[i].childNodes.length;j++) {
if (x[i].childNodes[j].nodeType != 1) continue;
searcharr.push(x[i].childNodes[j].firstChild.nodeValue);
}
var searchstrg = searcharr.toString();
if (searchstrg.match(objRegex)) {
var t;
var m=1;
if (document.Catalog.thumbImg[0].checked) {
var pn = "images/"+searcharr[2]+".jpg";
var container = document.createElement('TD');
var refLink = document.createElement("A");
refLink.setAttribute('href', "javascript:viewImg(\""+pn+"\")");
var imgHolder = document.createElement("IMG");
imgHolder.setAttribute("src", pn);
imgHolder.style.height = "75px";
refLink.appendChild(imgHolder);
container.appendChild(refLink);
container.className = "img"+rowColor;
row.appendChild(container);
}
for (t=0; t<searcharr.length; t++) {
container = document.createElement('TD');
var theData = document.createTextNode(searcharr[t]);
container.appendChild(theData);
container.className = 'line' + rowColor + '_' + m;
row.appendChild(container);
m++;
}
tmp.appendChild(row);
rowColor == 1 ? rowColor++ : rowColor--;
document.getElementById("replaceTxt").innerHTML = "";
document.getElementById("replaceTxt").appendChild(newEl);
noResult = "true";
}
}
if (noResult=="false") {
document.getElementById("replaceTxt").innerHTML = "<h3>Sorry, there was no match to your search. Please try again</h3>";
}
}
xmlDoc is the xml object from my import xml function. it is working correctly. IE does not give any JS errors, it just does nothing. If I put text in the Code: document.getElementById("replaceTxt").innerHTML
field, IE displays the text in the correct spot so I know the code is working. I also verified the data is being written correctly to "newEl" via IE 8 debugger. IE just does not want to append the newEl child to the <div> tag. This is where I assume the problem is. Hi Guys/Gals I am trying to do a small website for our family to keep track of each other's home address and etc.. using asp for the codes .. (its been ages since i indulge myself) i have 2 forms in which in FormA, i will key in the following address 666, ST Avenue #03-09 Anchor View Residence 123456 when i click on submit it shows this on FormB 666, ST Avenue #03-09 Anchor View Residence 123456 my question is how do i get it to be shown as 666, ST Avenue #03-09 Anchor View Residence 123456 in FormB in my formB.asp, for the particular code, all i wrote was Code: {Form.address}
I am in need of advise, have been stuck here for the past 1 day, not knwing wat to start or how to start. Thank you Hi. I have the following line in my HTML file <table class="bz_buglist" cellspacing="0" cellpadding="4" width="100%"> And I need to use javascript to change this line to <table id="main_table" class="bz_buglist" cellspacing="0" cellpadding="4" width="100%"> . I just need to add the ID part. How can I do this? Is there a method of replacing the line, or a way to "add attribute"? thanks! kev. Code: var bakaBanner;
bakaBanner = document.getElementById('head');
if (bakaBanner) {
var str=/\/images\/banners\/[A-Za-z0-9_]+.[a-z]+/;
document.write(str.replace(/\/images\/banners\/[A-Za-z0-9_]+.[a-z]+/, "http://img218.imageshack.us/img218/5904/revyblacklagoon1.png"));
}
Alright, here's the deal... This is a script to be used in Greasemonkey. The page this is for changes their banner every 5 minutes, the name changes and it could be either jpg or png. I'm fairly certain my regex itself: \/images\/banners\/[A-Za-z0-9_]+.[a-z]+ Is correct... Here's an example of what it's looking through: Code: <div id="head" style="background-image: url(/images/banners/kiminitodoke.jpg);" > <div id="header_left"> <div id="rss"> My guess is that it has something to do with this line: document.write(str.replace(/\/images\/banners\/[A-Za-z0-9_]+.[a-z]+/, "http://img218.imageshack.us/img218/5904/revyblacklagoon1.png")); I'm new with Javascript, so I don't really understand why it's not working... :/ I have been googling this for two days and am coming to the conclusion that the answer is no. Am I correct?
Alright I know about the problems IE has, but I'm testing out an id that is titled "slideRecord1" and trying to move it. The functions work with Firefox for the onmouseover and onmouseout attributes. But IE doesn't support that. So I'm trying to do it manually in the Javascript, but it's still not reading it. Any help? Code: /* <![CDATA[ */
document.getElementById('slideRecord1').onmouseover = function(){slideRecord(1);}
function slideRecord(disc)
{
var record = "disc"+disc;
var y = 20;
document.getElementById(record).style.top = y + 'px';
}
function unSlideRecord(disc)
{
record = "disc"+disc;
var y = 0;
document.getElementById(record).style.top = y + 'px';
}
/* ]]> */

Currently the background changes on the 1st link hover. is it possible to have different images load on the hover of different a's? any help would be appricated hi ! i have a div which some how i make when mouseover it become cursor and link to other page i wants to, and it has also some text inside of it which is also linked to other page and when mouseover on text it change colors too, but the problem is if mouse come on div it will not change the color of text inside of div, so what i wants is it will change the color of text too when mouseover on the div, here is code i am using: Code: <-- THIS IS IN CSS file -->
div.test{
position:relative;
font-family:Arial;
font-size: 12px;
padding-left: 82px;
padding-top: 47px;
width: 162px;
padding-bottom: 15px;
cursor:pointer;
cursor:hand;
}
div.test a{

text-decoration: none;
}
div.test a:hover{
color:#4E6D00;
text-decoration: none;
}
<-- THIS IS IN HTML file -->
<div onClick="document.location='otherpage.html';" class="test">
<a href="otherpage.html">here is all content,This is content hyperlinked</a>
</div>
you notice i am using cursor in css so when mouseover it becomes hand, what i wants is when it will become hand the text inside of it will also change the color, for now it change only if i mouseover to that text, thanks for any quick help please I am trying to alter Playa to use input type images instead of buttons. Part of this involves the need for a rollover image eg. a play button highlights when the cursor is over it. This is the code I have: Code: if (Playa.btnState == "Stop") {
document.getElementById("btnPlayStop").onmouseover = "this.src='images/stophover.gif'"
document.getElementById("btnPlayStop").onmouseout = "this.src='images/stop.gif'";
}
else {
document.getElementById("btnPlayStop").onmouseover = "this.src='images/playhover.gif'";
document.getElementById("btnPlayStop").onmouseout = "this.src='images/play.gif'";
}
<input type="image" src="images/stop.gif" onmouseover="this.src='images/stophover.gif'" onmouseout="this.src='images/stop.gif'" alt="Stop" id="btnPlayStop" onclick="Playa.doPlayStop();" />
Playa.btnState is the alt tag to say whether the state is stopped or started. I have the code working to alternate between "Play" and "Stop" images when the button is clicked, but the rollover doesn't happen. Any ideas? Thanks |
