JavaScript - Onmouseover Function Inside For Loop Not Working
Hi,
I hope someone can help me figure this out - it's been bugging me for a whole day now, and I can't seem to figure it out, and so far no Google research found this exact problem for me... Situation: I have a simple HTML page with one DIV element with the id "rotator". Inside that, JavaScript is supposed to create boxes that react to mouseovers. The weird thing is: The whole script works, but ONLY on the LAST box I create, no matter what I do. I can manually add the mouseover code to any one of these boxes, but it will only take on the last one. I can have JavaScript tell me the mouseover status of each box, and they all tell me they have code assigned correctly - but again only the last one works... Here's the relevant code (yes, highly abbreviated, but it's the part that fails on me): Code: var maxBoxes = 10;
function initSite() {
var rotator = document.getElementById("rotator");
rotator.innerHTML = "";
for (x = 0; x < maxBoxes; x++) {
rotator.innerHTML +='<div id="myBox' + x + '"></div><div id="myDark' + x + '"></div>';
// various other stuff about myBoxes[x] also in here, but not relevant to the issue I think
applyMouseActions(document.getElementById("myDark" + x);
debugOutput(document.getElementById("myDark" + x).id+"=" + document.getElementById("myDark" + x).onmouseover + "<br>", 1);
}
}
function applyMouseActions(item) {
if (!item) return;
item.onmouseover = function(ev) {
alert("does this work?");
var thisNum = this.id;
thisNum = thisNum.charAt(this.id.length-1);
var tempBox = myBoxes[thisNum].boxOb;
tempBox.style.background = "#fff";
}
item.onmouseout = function(ev) {
var thisNum = this.id;
thisNum = thisNum.charAt(thisNum.length-1);
var tempBox = myBoxes[thisNum].boxOb;
tempBox.style.background = "#aaa";
}
}
initSite is called in the body onload. All kinds of other animation parts are implemented that work fine, just this mouseover won't work. I have tried re-writing it in multiple different ways, including "xyz.onmouseover = myMouseCode" and then defining the function separately later - still no dice. So, the code creates 10 boxes (0-9) and 10 boxes that are on top of them to create a form of shadow effect depending on the position of the original boxes. Since the "myDark" boxes are on top of the "myBox" boxes, I apply the onmouseover onto the "myDark" boxes, but it only works on "myDark9" and no other box. They are all created the same way, the mouseover assigned the same way... All I can do is shake my head at it, but that doesn't fix the issue, obviously ;-) Any idea what else I can try? Thanks! Similar Tutorialshi i'd like to ask how can i ask for a function inside a for loop , if i remove the loop the code works fine but i need it for 10 rows . please help , here is the code PHP Code: $content .=' <table cellspacing="2" cellpadding="2" border="0" align="center" > <SCRIPT LANGUAGE="JavaScript" type="text/JavaScript"> function doCalcAndSubmit() { // get both values kolicina1 = document.forms["vlez1"].kolicina.value; cena1 = document.forms["vlez1"].cena.value; // do some calculation vkupno1 = kolicina1 * cena1; // set the value in the right field document.forms["vlez1"].vkupno.value = vkupno1; } </script> <form id="vlez1" name="vlez1" method="POST" action="index_execute.php" > <tr valign="middle"> <td></td> <td align="center"><b> Sifra : </b></td> <td align="center"><b> Kolicina : </b></td> <td align="center"><b> Cena : </b></td> <td align="center"><b> Vkupno : </b></td> </tr> '; for($t=1;$t<11;$t++) { $content .= ' <tr valign="middle"> <td>'.$t.'.</td> <td><input type="text" id="sifra" autocomplete="off" name="sifra['.$t.']" align="middle" onblur="normalField(this);" onfocus="fireKeyListener_sifra(event); highlightField(this,1);" onkeyup="getList_sifra(event);" size="25" value="" /></td> <td><input type="text" id="kolicina" name="kolicina['.$t.']" align="middle" size="25" ></td> <td><input type="text" id="cena" name="cena['.$t.']" align="middle" size="25" onblur="doCalcAndSubmit();"></td> <td><input type="text" id="vkupno" disabled name="vkupno['.$t.']" align="middle" size="25" ></td> <input type="hidden" name="hidden_data" value="'.$data.'"> </tr>'; } $content .= '<tr> <td></td> <td></td> <td align="center"><input type="submit" id="submit2" name="submit2" value="Potvrdi" ></td> </tr> </form> </table> '; Here's the code: Code: for (var i = 1; i < 5; i++)
var pl = eval("player" + i)
var namepl = eval("document.charInput.name" + i + ".value");
var skillpl = eval("document.charInput.skill" + i + ".value");
var genderpl = eval("document.charInput.gender" + i + ".value");
switch (skillpl) {
case "warrior":
pl = new player(namepl, skillpl, genderpl, 20, 15, 0, 5, 5, 2, 2, 3, 3, 0, 0);
logEntry("black", namepl + " is now a warrior.");
break;
case "mage":
pl = new player(namepl, skillpl, genderpl, 15, 10, 20, 2, 5, 5, 5, 2, 3, 0, 0);
logEntry("black", namepl + " is now a mage.");
break;
case "healer":
pl = new player(namepl, skillpl, genderpl, 15, 10, 20, 2, 5, 5, 5, 2, 3, 0, 0);
logEntry("black", namepl + " is now a healer.");
break;
case "archer":
pl = new player(namepl, skillpl, genderpl, 20, 15, 0, 3, 3, 2, 2, 5, 5, 0, 0);
logEntry("black", namepl + " is now an archer.");
break;
}
}
Each player has three form values: document.charInput.name1.value document.charInput.skill1.value document.charInput.gender1.value In the case of the 2nd-4th player, it changes to name2.value, etc. Based on these three inputs, I need to iterate through all four players and make the player object for each of them, as I've done above. If anybody has any ideas on how to correct this or an alternative method, please help. ok so Code: document.write("Goodbye!");
works but I put ^ that inside a function Code: function SayHello ()
(
document.write("Goodbye!");
)
and it stops working? I know the function call works because when I place some code to display an image in SayHello function, it displays the image. hi, i'm trying to pass variables from php to javascript ajax call using onmouseover, i loop a className to dynamically load the data into it, the problem is that all the elements affected and not the one i hover. JS: PHP Code: a = document.getElementsByTagName("span"); for (i=0; i<a.length; i++){ if (a[i].className == "stats") { a[i].style.display = "block"; a[i].innerHTML = req.responseText; } } PHP Code: <span class="stats"></span> <a href="javascript:void(0)" onmouseover="send_data(\'stats.php\', \''.$ip.'\')" ><img src="images/lock.png" alt="" /></a> thanks I have a img tag but I also added <img src="panada.jpg" onmouseover="alert('$info')"> can you tell me what I'm doing wrong?
hi. how can i get the value of title of<td> on onmouseover function. something like that. Code: <td title="mytitle" onMouseOver="func(this.title);"></td> can i do this. plzzzz help me I have six small images. Depending on which image a user hovers over, I would like a seventh image (a simple box) to change as well. For example, if a user hovers over image1, I want the seventh image to be a red box. If a user hovers over image2, the seventh image should be a blue box. Simple huh? So the seventh image changes color based on which of the six smaller images the user hovers over. ------------- So far, my current code only allows me to hover over any of the six images, and the seventh image always changes to the same image color. Code is below. Any help would be appreciated. Code:
<script type="text/javascript">
function hoverBox() {
var boxNumber;
document.getElementById("info").src = "Images/infoRedColor.png";
}
function hoverBoxOut() {
document.getElementById('info').src = "Images/info.png;"
}
</script>

Hello! I need a bit of help here, if possible. This code seems to work well with FireFox. It doesn't work so well with IE or Safari though. The onMouseOver event works properly (changes the bg-color and the bg-image) but the onMouseOut event doesn't work (it changes the bg-color back to normal but not the bg-image). I don't quite understand the problem. Code: <table cellspacing="0" cellpadding="0" width="230" height="20">
<tr>
<td class="font1" align="center" style="color:#2a78c6; background-color: #3c3c3c; background-image:url('images/nav-bg.png')" onclick="window.location.href='#'" cursor: pointer;
onMouseOver="this.style.color='c8c8c8'; this.style.backgroundColor='#2a78c6'; this.style.backgroundImage='url(images/nav-bg-hover.png)'"
onMouseOut="this.style.color='#2a78c6'; this.style.backgroundColor='#3c3c3c'; this.style.backgroundImage='url(images/nav-bg.png'">

Here is the website... http://pmportfolio.net/tester/. Also can't figure out how to get that drop-down menu working for IE, if anyone can lend a hand. Also can't get the gradients to work with IE 8. JavaScript Code: window.addEvent('domready',function(){
//SAMPLE 8
var handles8_more = $$('#handles8_more span');
var nS8 = new noobSlide({
box: $('box8'),
interval: 5000,
autoPlay: true,
items: $$('#box8 h3'),
size: 900,
handles: $$('#handles8 span'),
handle_event: 'mouseenter',
addButtons: {
previous: $('prev8'),
play: $('play8'),
stop: $('stop8'),
playback: $('playback8'),
next: $('next8')
},
onWalk: function(currentItem,currentHandle){
//style for handles
$$(this.handles,handles8_more).removeClass('active');
$$(currentHandle,handles8_more[this.currentIndex]).addClass('active');
//text for "previous" and "next" default buttons
$('prev8').set('html','<< '+this.items[this.previousIndex].innerHTML);
$('next8').set('html',this.items[this.nextIndex].innerHTML+' >>');
}
});
//walk to item 0 witouth fx
nS8.walk(0,false,true);
});
html Code: <div class="slider sample8"> <p class="buttons" id="handles8"> <span>Item 1</span><span>Item 2</span><span>Item 3</span><span>Item 4</span><span>Item 5</span> </p> <div class="mask1"> <div id="box8"> <div onMouseOver="nS8.Stop();" onMouseOut="nS8.Play();"> </div> </div> </div> <p class="buttons"> <span id="prev8"><< Previous</span> | <span id="next8">Next >></span> </p> <p class="buttons"> <span id="playback8">< Playback</span> <span id="stop8">Stop</span> <span id="play8">Play ></span> </p> </div> All I need to do is when they hover ocer the div statement stop the program from looping. and then when they stop hovering over it let it start looping again. Hey all, I have a little function that performs when a form item is selected. I would like to give the form items all at once and have the function perform when the user mouses over an item in the displayed list. Here is the form code: Code: <form> <select onchange="showRSS(this.value)"> <option value="">Select an RSS-feed:</option> <option value="Google">Google News</option> <option value="MSNBC">MSNBC News</option> </select> </form> thanks a bunch, Brian p.s. I tried this but it didn't work Code: <?php echo("<a href=\"http://www.msn.com\" onMouseover=\"showRSS(this.MSNBC)\">MSNBC News</a>");?>
<br />
<?php echo("<a href=\"http://www.google.com\" onMouseover=\"showRSS(this.Google)\">Google News</a>");?>
<br />
Is it possible to set onmouseover only in js file without running the function on html code? P.S. I found a coding thread here but I don't understand it and it's too old (2005 archive). Thank you very much Ok, I'm nearly pulling my hair out with this one. I have been looking at this code for two evenings now, and rewrote it 4 times already. It started out as jQuery code and now it's just concatenating strings together. What I'm trying to do: Build a menu/outline using unordered lists from a multidimensional array. What is happening: Inside the buildMenuHTML function, if I call buildMenuHTML, the for loop only happens once (i.e. only for 'i' having a value of '0'.) If I comment out the call to itself, it goes through the for loop all 3 times, but obviously the submenus are not created. Here is the test object: Code: test = [
{
"name" : "Menu 1",
"url" : "menu1.html",
"submenu" : [
{
"name" : "menu 1 subitem 1",
"url" : "menu1subitem1.html"
},
{
"name" : "menu 1 subitem 2",
"url" : "menu1subitem2.html"
} ]
},
{
"name" : "Menu 2",
"url" : "menu2.html",
"submenu" : [
{
"name" : "menu 2subitem 1",
"url" : "menu2subitem1.html"
},
{
"name" : "menu 2subitem 1",
"url" : "menu2subitem1.html"
} ]
},
{
"name" : "Menu 3",
"url" : "menu3.html",
"submenu" : [
{
"name" : "menu 3 subitem 1",
"url" : "menu3subitem1.html"
},
{
"name" : "menu 3 subitem 1",
"url" : "menu3subitem1.html"
} ]
}
];
Here is the recursive function: Code: function buildMenuHTML(menuData,level) {
var ul;
if (level == 1) {
ul = "<ul id='menu'>";
} else {
ul = "<ul class='level" + level + "'>";
}
for (i = 0; i < menuData.length; i++) {
menuItemData = menuData[i];
ul += "<li>";
ul += "<a href='" + menuItemData.url + "'>" + menuItemData.name + "</a>";
if (typeof menuItemData.submenu != 'undefined') {
ul += buildMenuHTML(menuItemData.submenu,level + 1);
}
ul += "</li>";
}
ul += "</ul>";
return ul;
}
Here is how the function is called initially: Code: buildMenuHTML(test,1); This is it's return value (with indentation added for readability): Code: <ul id='menu'>
<li><a href='menu1.html'>Menu 1</a>
<ul class='level2'>
<li><a href='menu1subitem1.html'>menu 1 subitem 1</a></li>
<li><a href='menu1subitem2.html'>menu 1 subitem 2</a></li>
</ul>
</li>
</ul>
'Menu 2' and 'Menu 3' don't show up! I'm sure it's something small that I'm overlooking, but any help would be appreciated. Hello I have created awebpage here with an onmouseover slideshow, adapted from the Cut & paste Onmouseover Slideshow from Javascript kit This works in IE8 but not in Firefox or Chrome. I appreciate this may have been previously solved but I cannot find it in the threads. Hi, Any one help me In one variable i have some data ex: var data = document.getElementById("imageId").value; I want to pass this data to another function inside another function ex: var button1 = '<img src="images/Remove-button.gif" width="70" height="15" onclick="removeVerifyImageRow(this),saveLibData('+data+')"/>'; while running the application i am getting an error incase if the data is string ex:if data is 'image1' i am getting an error, but with number there is no problem ex: if data is '1122'. this is very urgent to solve this problem plz any one help me How can I call a PHP Function inside a Javascript Function? This is what I have so far, but I don't think I'm doing it the right way. Any suggestions? PHP Code: <?php function phpQuery(){ $query = mysql_query("INSERT INTO mytable VALUES('','name','email')"); } ?> <script type="text/javascript"> function delayQueries() { timeoutID = window.setTimeout(doQueries, 2000); } function doQueries() { var runQuery = "<?php phpQuery(); ?>"; } </script> Thank you in advance if someone can help. I have been banging my head against the wall for hours now. Here is the code: Code: for (var i = 0; i < BS_crm['activityTypes'].length; i++) {
var clickFunc = function(){ activityList.showForm( -1, {blockType:[""+BS_crm['activityTypes'][i]['id'], "0"]} ); };
var type = {
value: BS_crm['activityTypes'][i]['id'],
label: "Add New "+BS_crm['activityTypes'][i]['label'],
css: BS_crm['activityTypes'][i]['css']+"_16",
onClick: clickFunc
};
previewLinks.items.push( type );
}
Now, basically what I am doing here is running through one array to create an array of objects, that will be used to create links that will use whatever onClick function I pass it. The problem is that on the second line I need the BS_crm['activityTypes'][i]['id'] to be a value, not a reference. If that line was simply changed to: Code: var clickFunc = function(){ activityList.showForm( -1, {blockType:["3", "0"]} ); };
then everything would work as I need. How can I make this happen? I would really appreciate any help. Thank you again in advance. Hi... I just want to know if it is possible to have an autocalculate in a textboxes inside while loop?and if it is possible how?.. here is my code: Code: <html>

I have table : parameter settings and i have fields: PCODE, max, min PCODE has data: PXX PYY PZZ PAA PBB Total I just want to know how can I auto calculate the total max and total min and it will display in the textbox beside Total... Thank you Hi, I have this loop: Code: for (var j = 0; j < gmarkers.length; j++) {
gmarkers[j].hide();
elabels[j].hide();
map.closeInfoWindow();
var str=gmarkers[j].myname.toLowerCase();
var patt1=inp;
if (str.match(patt1))
{
found = true;
gmarkers[j].show();
count++;
var p=j;
}
}
which was useful for passing the p variable when it was just one number. but now I need to get that number every time j gets set (I understand that the j gets overwritten each time the loop goes through). What would be ideal is if p could become an array, the contents of which match the values that j has passed though during the loop cycle. I thought var p = new Array (j); minght do the trick, but obviously not... I hope that I'm explaining it OK, and that it's possible, and that somebody has an idea how to do it... I have the following code: ... var numberoffiles = array(); for (i = 1; $i <= totalNumberOfFiles; i++) { numberoffiles[i] = i; } ... I get an error saying that numberoffiles is undeclared or something What am I doing wrong? Do I need to declare it a global variable or something?? ALSO, why can't I do this: numberoffiles[] = i; I've seen code snippets that assign to the end of an array like this (Or maybe my problem is the scope of the variable??) Thanks OM |
