JavaScript - Image Map, Tooltips Modification

I have a scenario where I show a drop-down-with-few-items in a JSP page, to the user.
The length of few options in the drop down is greater than that of the drop down's, hence our requirement is to show the hovered (not selected) option as tooltip for user's convenience. I am not able to use title attribute for displaying tooltips in my browser.
Now the code in http://dossett.org/11/No_onmouseover_for_options_in_IE/
implements a tooltip for multiple select drop down menu.Can you modify the code for single select

Hello,

I found jkmegamenu (http://www.javascriptkit.com/script/...megamenu.shtml) beneficial for my website.

As there is a delay time for hiding the menu by default, however I could not succeed for the required modification to set an delay time prior to popup the menu.

I paste the code below and marked the part that I know to set something for the delay for mouse enter, in red.

I need your advice for the modification needed to be able to apply the same delay time prior to pop up the menu.

Thanks.

Code:

jQuery.noConflict();

var jkmegamenu={

effectduration: 0, //duration of animation, in milliseconds
delaytimer: 300, //delay after mouseout before menu should be hidden, in milliseconds

//No need to edit beyond here
megamenulabels: [],
megamenus: [], //array to contain each block menu instances
zIndexVal: 1000, //starting z-index value for drop down menu
jqshimobj: null,

I have been successfully using the following "myAjax" function to load text file information from the server.
Code:

// ajax.js
// From: http://www.webdeveloper.com/forum/showthread.php?t=245681
//  and: http://www.webdeveloper.com/forum/showthread.php?t=245694

var myAjax = {
  TextInformation : '',
  myAjaxIO : function (U, V) { //LA MOD String Version. A tiny ajax library.  by, DanDavis
    var X = !window.XMLHttpRequest 
	  ? new ActiveXObject('Microsoft.XMLHTTP') 
	  : new XMLHttpRequest();
    X.open(V ? 'PUT' : 'GET', U, false );
    X.setRequestHeader('Content-Type', 'text/html');
    X.send(V ? V : '');
    return X.responseText;
  },
  doLoad : function (filename) { this.TextInformation = this.myAjaxIO(filename); },
  getTextInfo : function () { // alert(this.TextInformation);  // for testing purposes
    return this.TextInformation }
}
/* example
function Load_and_Show(filename) {
  myAjax.doLoad(filename);
  document.getElementById('TArea').value=myAjax.getTextInfo();
}
*/

After I load the text file, I store the text "records" into an array by doing something like this:
Code:

  var Recs = myAjax.getTextInfo().split('}');

Where the '}' character is my record delimiter. It could just as easily be '\n' or '\r' or the like.
Again, I am not having any problems doing it this way as it suits my current needs.

Now the question(s)
1. Does the call to read the text data from the external file
always read in the entire contents or can I read one line or delimited record
at a time and store it to the array directly without the text storage?

2. If the text is always read completely (my suspicion), can I safely delete
the "TextInformation" after I convert to the array format? Is there any memory
penalty for doing it this way as the text information can be somewhat lengthly
and I don't like the idea of having doubled memory usage when I only need the information in array format anyway?

This is the idea I am considering, but I don't know if there are drawback to this method of if there is a better way to accomplish the task.

Hi all,

I'm justing wondering about the behavior of JS in regards to adding elements, suppose I have something like this

Code:

<div id="myDiv"></div>
...
function test() {
    for (i=0 i<100; i++) {
        var obj = document.create("div");
        // do stuff to style div and set content
        document.getElementById("myDiv").appendChild(obj);
    }
    // DO SOMETHING WITH ONE OF THESE DIVS
}

I'm just wondering at the point I hit that "// DO SOMETHING WITH ONE OF THESE DIVS", are all the divs I have added in the DOM available to access?

I ask because I have some code at work in which a tester is reporting an error that happens which I can't reproduce, and they and others have had it a few times.

The only way I can explain it in my mind is if the div is not available to me at the time of execution. So I'm just looking to rule it out or confirm my hunch.

Is document.getElementById("myDiv").appendChild(obj); synchronous and the next line of code wont execute until the DOM is ready or is it in fact a asynchronous call and therefore adding alot of elements to the DOM could result in a lag so some divs or not available straight away.

Any information much appreciated, I hope I have been clear enough. I'm using IE7 and so are the testers.

Thanks,
Dale

Hello, Im a coding noob and trying to make this widget display in 3 columns. Can some one help me? I am able to do it with simple css modifications, but the container still only shows up as 1 column rather than 3. Any ideas?

Hi gurus,

I am developing an application in which I am using a client validation library called "livevalidation". When you attach with the input control it shows a message infront of the text box if you leave it empty. But I want to modify it and want to show a image (cross) infront of the text box and message below text box.

Here is the CSS file and html file.
------------------------------------

Code:

/********************************* LiveValidation *************************************/


.LV_valid {
    color:#00CC00;
 }
	
.LV_invalid {
	color:#CC0000;
}
	
.LV_validation_message
{
    clear: both;
	text-indent: 166px;
	height: 22px;
	line-height: 22px;
	font-size: 11px;
	font-weight: bold;
}

    
.LV_valid_field,
input.LV_valid_field:hover, 
input.LV_valid_field:active,
textarea.LV_valid_field:hover, 
textarea.LV_valid_field:active,
.fieldWithErrors input.LV_valid_field,
.fieldWithErrors textarea.LV_valid_field {
    border: 1px solid #00CC00;
}
    
.LV_invalid_field, 
input.LV_invalid_field:hover, 
input.LV_invalid_field:active,
textarea.LV_invalid_field:hover, 
textarea.LV_invalid_field:active,
.fieldWithErrors input.LV_invalid_field,
.fieldWithErrors textarea.LV_invalid_field {
    border: 1px solid #CC0000;
}

HTML
------
Code:

<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
    <title></title>
    <script src="livevalidation.js" type="text/javascript"></script>
    <link href="StyleSheet.css" rel="stylesheet" type="text/css" />
</head>
<body>
<form id="create_account" action="">
           Say hello: 
    
           <input id="sayHello" type="text" /> 
           
     <script type="text/javascript">
              var sayHello = new LiveValidation('sayHello', { validMessage: 'Hey there!', wait: 500 });
              sayHello.add(Validate.Presence, { failureMessage: "Don't just ignore me, I wanna be your friend!" });
          </script>
  </form>
</body>

</html>

For livevalidation javascript (.js) i cannot paste here as its quite big and forums is not allowing me paste it so kindly get it from here which I need to modify.

here is the link.
----------------
http://livevalidation.com/javascript..._standalone.js


In the above file there is a function called "createMessageSpan" I've tried to modify it as I am sure this is the function which needs to be modified but how to do it that i dont know as i am not a java specialist.

Please help I would really appreciate.

Hello,

I am using the following javascript breadcumb script (found here http://www.javascriptsource.com/navi...eadcrumbs.html )

It works perfectly, except I'm trying to figure out how to remove and replace the "dash" ( - ) character with a space?

Code:

function breadcrumbs() {
  sURL = new String;
  bits = new Object;
  var x = 0;
  var stop = 0;
  var output = "<div class=topnav><a href=/>Home</a> > ";

  sURL = location.href;
  sURL = sURL.slice(8,sURL.length);
  chunkStart = sURL.indexOf("/");
  sURL = sURL.slice(chunkStart+1,sURL.length)

  while(!stop){
    chunkStart = sURL.indexOf("/");
    if (chunkStart != -1){
      bits[x] = sURL.slice(0,chunkStart)
      sURL = sURL.slice(chunkStart+1,sURL.length);
    } else {
      stop = 1;
    }
    x++;
  }

  for(var i in bits){
    output += "<a href=\"";
    for(y=1;y<x-i;y++){
      output += "../";
    }
    output += bits[i] + "/\">" + bits[i] + "</a> > ";
  }
  document.write(output + document.title);
  document.write("</div>");
  }

Any help would be greatly appreciated.

Thank you!

I'm working on a website for a freelance writer. I've used a lytebox mod to open a modal dialogue box that shows a scan of each magazine article. The code allows for an "info" button at the bottom of the window, which when clicked calls a page info.php, and populates that page with text from an [info] variable on the main page.

My question is this. I'd like to use the "info" button to call entire articles in text format from a separate php page. I don't want to insert these long articles into the main page. Is there an easy way to do this in the code?

The info.php page code follows:

<div class="info"><?php
if (isset($_GET['info'])){
$text = $_GET['info'];
$text = str_replace('<br/>',"\n",$text);
} else {
$text = 'This page is showing text from GET "info" variable';
}
echo $text;
?></div>

The entire info.php page is he
http://www.mimiread.com/info.php

The main lytebox.js page that I'm using is he
http://www.mimiread.com/lytebox.js


The code line that calls this from the main page:
<a href="images/ttlnob-cover.jpg" rel="lytebox[essays-ttlnob]" rev="[info]ttlnob.html[/info]" title=""><img src="images/essays-ttlnob.jpg" border="0" alt="house beautiful, the trying to leave new orleans blues" /></a>


Any help would be appreciated.

In my previous post, I asked how to create a function that would allow me to add to or subtract from a maxvalue, and thankfully I got help regarding that. However, something's got me stumped for the past few weeks that I still can't resolve...

This is the relevant code:
Code:

<html>
<head>
<script type="text/javascript" language="Javascript">
function chgAdv(btn)
{
	var form = btn.form;
	var newqty = parseInt(btn.value);
	var maxqty = form.maxqty;
	var maxadv = form.maxadv;
	
	if (eval("btn.checked") == true && parseInt(maxadv.value) + newqty <= 15) {
		var newmax = parseInt(maxqty.value) - newqty;
		var newadv = parseInt(maxadv.value) + newqty;
	}
	else if (eval("btn.checked") == false && parseInt(maxadv.value) - newqty >= 0) {
		var newmax = parseInt(maxqty.value) + newqty;
		var newadv = parseInt(maxadv.value) - newqty;
	}
	else {
		var newmax = parseInt(maxqty.value);
		var newadv = parseInt(maxadv.value);
	}
	
	if ( newadv >= 0 && newmax >= 0) {
		maxqty.value = newmax;
		maxadv.value = newadv;
    }
}

function chgDis(btn) {
	var form = btn.form;
	var newqty = parseInt(btn.value);
	var maxqty = form.maxqty;
	var maxdis = form.maxdis;
	
	if (eval("btn.checked") == true && parseInt(maxdis.value) + newqty <= 10) {
		var newmax = parseInt(maxqty.value) + newqty;
		var newdis = parseInt(maxdis.value) + newqty;
	}
	else if (eval("btn.checked") == false && parseInt(maxdis.value) - newqty >= 0) {
		var newmax = parseInt(maxqty.value) - newqty;
		var newdis = parseInt(maxdis.value) - newqty;
	}
	else {
		var newmax = parseInt(maxqty.value);
		var newdis = parseInt(maxdis.value);
	}
	if (newdis >= 0 && newmax >= 0) {
		maxqty.value = newmax;
		maxdis.value = newdis;
	}
}
</script>
<link rel="stylesheet" type="text/css" href="styles.css">
</head>
<body>
<form name="f1">
<b>Advantages</b> (<input type="text" class="RO" name="maxadv" value="0" />)<br />
<input type="checkbox" class="RO" name="Absolute Direction" onclick="chgAdv(this);" value="2" />Absolute Direction<br />
<input type="checkbox" class="RO" name="Allies" onclick="chgAdv(this);" value="3" />Allies<br />
<hr>
<b>Disadvantages</b> (<input type="text" class="RO" name="maxdis" value="0" />)<br />
<input type="checkbox" class="RO" name="Antisocial" onclick="chgDis(this);" value="2" />Antisocial<br />
<input type="checkbox" class="RO" name="Ascetic" onclick="chgDis(this);" value="4" />Ascetic<br />

max quantity: <input type="text" readonly class="RO" name="maxqty" value="40" />
</form>
</body>
</html>

styles.css is simply:
Code:

input.RO {
    border: none; 
    width: 40px;
    text-align: center;
}

As it stands, it works as long as the total value is less than or equal to the limit (for advantages it's 15, for disadvantages it's 10). However, the moment it goes past the limit -- for instance, if you change Antisocial's value from 2 to 7, or if you add several additional checkboxes with any values -- the whole thing starts going crazy; specifically, maxvalue doesn't revert to 40 when the all the checkboxes are unchecked.

What I'd want to happen is that the user cannot select or apply advantages or disadvantages if the maximum advantage is greater than 15 or the maximum disadvantages is greater than 10.

I'm thinking that a button for adding disadvantage points to/subtracting advantage points from the maxvalue (that becomes disabled if the user goes past his limit on advantages/disadvantages) is useful at this point, but I'm really stumped on the implementation of the idea. An alternate idea of mine is that all other advantage/disadvantage checkboxes would become disabled if their value is greater than the remaining number of points, but I don't know how that is possible either.

Any and all help is greatly appreciated.

Hi all, please help...
There is a small, but very usability script - Multiple Dynamic Combo Boxes by Elviro Mirko (http://www.javascriptkit.com/script/...plecombo.shtml). Since there are many versions of this script. One of them, which I did.

**Or are there any other JS solutions that satisfy my request

I would be grateful for any aid....

Hello, I am very new to javascript and most programming in general, but I am trying to make a simple game with a ball and paddle. The catch is the user inputs the height, width and speed of the ball, then when the start button is hit, the program runs...

I was successfully able to make the ball bounce in a preset box (it was 500x500) but I am struggling to get the code to work when the user types in the values the ball either goes crazy or does not work. I have tried many things, but nothing has worked. the code I included is my most recent attempt. I am not asking for you guys to do the whole game for me, I would just like to know the solution to why my code is not working and any suggestions

the ball is 15x15px btw

Thanks,

i have image button i need to display image .if the size of the image button is 100*100 and image size is 50*50 .the remaining space of the image button should be empty.the image should not stretch.

can any one guide me i am new to programming

Thanks in advance!!!

I have gotten my script to do exactly what I want it to do with one exception. I have some thumbnail images that people can mouse over and the actual image is 100px by 75px. That is what I use for my thumbnail and they reside in www.website.com/images/thumbs/image1.jpg. I have the large version of the image that resides in www.website.com/images/image1.jpg. Its actual size is 640px by 480. When I mouse over my thumbnail, I don't want the thumbnail to appear for the larger image, I want the large image to appear instead? Let me know if you need ellaboration. Any help would be great! Thank you.

Javascript
Code:

   <script language="JavaScript">
function Change_Big_One(thumb){
document.getElementById('BigOne').src=thumb.src.replace("_th","")
}
</script>

HTML THUMBNAIL
Code:

<div><img src="https://www.website.com/images/thumbs/image1.jpg" class="thumb" onMouseOver="Change_Big_One(this)"></div>

HTML LARGER IMAGE
Code:

<div><img src="" id="BigOne"></div>

QUESTION 1:

Hello. I would like to know if this is possible with Javascript, and if yes, if someone can please provide me with the code or point me in the right direction.

Let me start of by saying that this is for an eBay listing. I know that they accept basic / limited javascript and if what I am asking is possible, I hope that it can work on eBay listings.

I would like to know if it's possible to determine the dimensions of an image with Javascript from an Image url, and to then resize it or not based on the the size of the image.

So, let's say this is the URL: www.adomainname.com/image.jpg

and let's say that image is 1400 px x 1400 px. I would first like the javascript code to detect that size. I also would like the maximum dimension for any side of the image to be 600 px. If both sides of the image are over 600 px, for both sides to be reduced proportionally to 600 px or lower. If any one side of the image is larger than 600 px, the image is to be resized to 600 px or lower. If both sides are under 600 px, the image is to not be reduced. It would also be nice if it can detect whether the image is portion or landscape based on I guess the larger side, because an image at 600 px in height might be too big, but in width might be o.k.

So, in this example (the 1400 px by 1400 px), the image is to be resized to 600 px x 600 px.

For an image that's 300 px x 500 px, it should remain as such.

For an image that's 400 px x 700 px, it should be resized to 400 / (700 / 600) px by 600 px, which is approximately 343 px x 600 px.

I have looked a bit into this and I see things being mentioned about the image being loaded first completely on the screen, or about using server side language like PHP, and so on, but like I said, keep in mind that this is for eBay, and so I am limited.

Note: The part that I am most interested in is in being able to detect the size / dimensions of the image.

QUESTION 2:

On a side note, does anyone know if it's possible to have a Javascript enlarging function for images, in which when one clicks on an image, it is enlarged, but either in a popup window that's smaller than the one behind it, and possibly centered, or by making the background go dark and then bringing up the enlarged image (is the latter done with Javascript; I have seen this effect for a while now and have always wondered.)

Hello,

I am working on a page that has a jQuery full browser BG image and I am trying to also utilize a MooTools gallery. There seems to be some interference between the two JavaScripts as only one works (whichever one is last in order in the header of the HTML document).

I am a complete novice with JavaScript so if anyone could help that would be great.

Thank you in advance.
