Cleaning Up/fixing Code
May 12, 2007
I have a preloading page on my site for several images. When I run the code for the preloading page through the W3 validator, I get these error messages:
character "<" is the first character of a delimiter but occurred as data.
there is no attribute "name". document type does not allow element "img" here.
I tried correcting the second and third errors, but ended up messing up the whole script. If someone could fix these errors and just clean up the code in general, that would be helpful. By the way, the doctype is XHTML 1.0 strict. Code:

I am trying to apply it to my page. But when I click on a thumbnail, although it's opening a pop-up window, it also enlarges the image in the current browser.I also need to do the same thing with a .swf file. How can I have a flash movie enlarge when clicked?

I need to fix the communication between the JS located in this page and the PHP form script. When the form is submitted I want the page to automatically update which is already present in the script, thanking the user for the submission. Since the PHP script was changed that communication is broken and I hope to get it communicating once again.

I have a real problem with the google maps API in IE7/8, the "powered by google" which i can't remove due to the t&c's loses its alpha transparency when i apply opacity to it "to acheive the sliding in effect" seen here: [URL] I'm trying to set the alpha back using this:
Code:
$('#map_canvas div div a div div').css("filter","progid:DXImageTransform.Microsoft.AlphaImageLoader(enabled=true,sizingMethod=crop,src=http://maps.gstatic.com/intl/en_gb/mapfiles/poweredby.png)");
(jQuery)
But this does not seem to do anything, and looking at the source in firebug Lite for IE, it seems this is already set on multiple div's surrounding the logo anyhow.

I have created the following function to expand a container depending on which one is hovered over, but need some advice on how to tidy it up.
There are four containers in all: three expand to the right and the final one expands to the left. There is a hidden element in the expandable area which appears when the container has fully expanded. For example: if I hover over .sub-main section.other, then the hidden div .other .right fades up. Mouseout and it fades down quickly as the .sub-main section.other retracts.
The working example is here: [URL]
The following code does work, but I am aware that it could probably be reduced to half as many lines using some conditional cleverness:
$(document).ready(function(){
// Hides right or left divs depending on the block
$('.other .right').hide();
$('.end .left').hide();

const notWhitespace = /S/
function cleanWhitespace(node) {
for (var x = 0; x < node.childNodes.length; x++) {
var childNode = node.childNodes[x]
if ((childNode.nodeType == 3)&&(!notWhitespace.test(childNode.nodeValue))) {
// that is, if it's a whitespace text node
node.removeChild(node.childNodes[x])
x--
}
if (childNode.nodeType == 1) {
// elements can have text child nodes of their own
cleanWhitespace(childNode)
}
}
}
document.addEventListener("load", function() {
cleanWhitespace(document)
}, true)
This script is intended to remove whitespace text nodes from a document. These nodes show up far more often than we want to admit, and leads to a DOM that is different in Mozilla than IE.
Make sure you use this only in documents where whitespace is expendable. XHTML documents are among these, as are MathML expressions and SVG images.
Theoretically, whitespace can be significant in some XML documents.

I have an ajax based page, which loads content from external page (html +js) So if i have a div "update_div" being updated with external content (html+js)
Let me be more specifig
Step1: Ajax content along with js loaded into update_div from a.html
Step2: Ajax content along with js loaded into update_div from b.html
What happens to the js loaded from a.html? Is it lurking in the memory or automatically/magically removed from the browser memory? I am afraid of memory leaks, if the js is still lurking in memory, the more ajax calls made, the more js is going to be held up in memory. Unless am totally wrong; i have no idea of the mechanism happening.

I don't like the way that a link to page top leaves the location bar with something like '#top' appended to it.
So, I'm hooking a listener to the link click event, doing a window.scroll and stopping default action. This is fine as long as the location doesn't already have a hash portion. When it does, I'd like to clean that up without causing a page reload or any server requests.
Is this possible? The closest I got with MSIE is to remove the tail end, but I can't get rid of the actual '#'.

here is the page I'm working onhere is the jQuery in use
$(document).ready(function() { $('.error,.success').hide(); $("#send").click(function (){ $('.error,.success').hide("slow"); $.ajax({ url: 'add.php?lnk='+$.URLEncode($('[name=lnk]').val())+'&
[code]....
and in this code, it works, the call is made and text is added. in the other code I don't get a change at all. Not even in the database that add.php manipulates.

I am trying to make a gui for clients to edit a php page that displays html and javascript.
I want the user to be able to move html elements around and even edit it like add effects like fade in and out etc.
Then after all the changes I want to overwrite the existing php file that does this for that user. how can you make such changes and then save it to a file?
It's an html / javascript editor but using a gui instead of allowing them to directly touch the code. It would be a security risk if I allow such a thing. So I need to program a interface that would make such changes and save them to file.
Like how can you delete and add new javascript code to the file?

I am a novice, almost to an intermediate-level JavaScript guy, so much of this is new to me. I appreciate your patience reading this.
I have a routine that creates some HTML on the fly (updateFilters() function) and after the HTML is created, I attempt to access some fields (elements) on the form itself.
I works fine if I place an alert() statement after the HTML is created, but when I remove, the code errors out.
I have tried the setTimeout() statement, but I cannot grab the element --- undefined or null is returned. It seems that the form is the only element I can get a handle on --- everything else is undefined or null...
Here is the code:
function editQuery() {
var f;
var x;
var myForm = document.forms[0];
// Get the row filters that were used in the last query..
for (f = 1; f < 16; f++) {
var filter = eval("myForm.FilterList_" + f);
if (filter.selectedIndex > 0) {
var methodElement = element("FilterMethod_" + f);
var methodIndex = methodElement.selectedIndex;
var savedFilterMethodValue = methodElement.options[methodIndex].text;
var choicesElement = element("FilterChoices_" + f);
var choicesIndex = choicesElement.selectedIndex;
if (isNaN(choicesIndex)) {
var savedFitlerValues = choicesElement.value;
}
else {
var savedFitlerValues = choicesElement.options[choicesIndex].text;
}
updateFilters(filter); // update the filters
// take the saved methods and values and then update the selections
// Alert here makes the code work..
// alert("Try this");
// Wait for HTML..
setTimeout("completeEdit()", 1000);
function completeEdit() {
// Since the object was updated, get the object again..
var methodElement = element("FilterMethod_" + f);
for (x = 0; x < methodElement.options.length; x++) {
if (methodElement.options[x].text == savedFilterMethodValue) {
methodElement.options[x].selected = true;
break;
}
else {
methodElement.options[x].selected = false;
}
}
// Since the object was updated, get the object again..
var choicesElement = element("FilterChoices_" + f);
for (x = 0; x < choicesElement.options.length; x++) {
if (choicesElement.options[x].text == savedFitlerValues) {
choicesElement.options[x].selected = true;
break;
}
else {
choicesElement.options[x].selected = false;
}
}
// Only display next row if f = 2..
// If only one row was used, no reason display the next row..
if (f == 2) {
displayNextFilter(f - 1); // display it
}
}
clearTimeout(timeOut);
}
}
}
Do I have to pass the object (the form, the elements) to the completeEdit() function in the setTimeout() statement?

I am trying to hide this code:
HTML Code:
using this code
HTML Code:
This works fine when I place this code under the html in the main source, but if I try to add this Jquery code to an external js sheet it doesnt seem to work?
Currently my js sheet is called in the header, when I move this link to the footer of my page the code works again, so Im guessing this has something to do with where the jquery code is placed in relation to the code Im trying to hide?
How I can keep my js in the header but still make the content disappear on click?

I hope whether such a script exists for what am wanting to do. From time to time, I need to send password information or login details and password information to some users. At the moment, am doing it via email with a subject named FYI and the body of the email basically just contain the login and the password or in some case, just the password. What am wanting to know is whether I can put these information into a HTML file which contains an obfuscated Javascript with a button that a user will click that will prompt for his login information and then will display the password. In its simplest form, I guess I am looking for a Javascript that will obfuscate a HTML file that contains the password. I found some website that offers such service as obfuscating a HTML file but am hoping it can be done via a Javascript so it is at least "portable" and I do not have to be online.

I am about to port an app using html, css, and javascript where most of the content is mixed with the presentation and behaviour.
The question I have been asked is: even though this older style is difficult to maintain, will the method proposed my the authors of Simply Javascript perform adequately on a page with hundreds of entries like the one below? Using the newer method, the program would have to iterate through all the elements on the page and assign handlers for click, mouseover, etc. Please advise. Code:

1. When I have the "<textarea>" code lines in it put a text-area on the page, but it puts all of the code following that first text-area line into the text-area box and doesn't execute that segment of code.
2. When there is no "<textarea>" (for the sake of seeing if the rest of it worked) it doesn't check the survey.
I'm stumped and can't figure out what to do at this point Code and pictures follow:
