Making Javascript Code Deploy Ready

I need to make this code deploy ready. I can't hard code these URL's in but for some reason any other way of coding this, breaks. Reference this question here: Upon Redirect of Form Submission within iFrame jQuery Not Detecting Updated Src Attribute
I basically need to have the switch check if the location CONTAINS the page name after 'settings/' i.e. iframe-home.php, update.php, or changepassword.php. I think thats how i fix this issue? But i'm not sure how. (Hope that makes sense)
Here is the code:
$(document).ready(function() {
$('iframe#settings-iframe').on('load', function() {
var location = this.contentWindow.location.href;
console.log('location : ', location);
switch (location) {
case "http://localhost/Makoto/profile/settings/iframe-home.php":
console.log(location);
activateHome();
break;
case "http://localhost/Makoto/profile/settings/changepassword.php":
console.log(location);
activatePassword();
break;
case "http://localhost/Makoto/profile/settings/update.php":
console.log(location);
activateName();
break;
}
});
});

Note I assume that you want dynamically check path without host part.
Create new link element, set href to location, compare it to pathname
// replace with this.contentWindow.location.href
var url = "http://localhost/Makoto/profile/settings/iframe-home.php";
/**
* http://localhost/Makoto/profile/settings/iframe-home.php
* will return /Makoto/profile/settings/iframe-home.php
*/
var link = $('<a>', {
href: url
})[0].pathname;
var parts = link.split('/');
var file = parts[parts.length - 1];
console.log(file);
switch (file) {
case "iframe-home.php":
activateHome();
break;
case "changepassword.php":
activatePassword();
break;
case "update.php":
activateName();
break;
}
function activateHome() {console.log('Activating home');}
function activatePassword() {console.log('Activating password');}
function activateName() {console.log('Activating name');}

Ideas for a correct function on my webpage?

I am having problems with a javascript function. I want to replace an icon by changing the class.
On my page, I have the following element:
<i class="wait icon" alt="{webui_botstatenotavailable}" title="{webui_botstatenotavailable}" id="{botname}"></i>
The following javascript should change the class, but it does not work:
function incomingBotStatusList(http_request, statusOff, statusOn)
{
if (http_request.readyState == 4)
{
if (http_request.status == 200)
{
if (http_request.responseText.length < 7)
{
// Error
}
else
{
var botStatusList = JSON.parse(http_request.responseText);
for (var key in botStatusList)
{
if (botStatusList.hasOwnProperty(key))
{
var botStatusImage = document.getElementById(key);
if (botStatusImage != null)
{
if (botStatusList[key] == 0)
{
botStatusImage.class.innerHTML = "images/bullet_red.png";
botStatusImage.title = statusOff;
botStatusImage.alt = statusOff;
}
else if (botStatusList[key] == 1)
{
botStatusImage.class.innerHTML = "<i class=\"checkmark green icon\">";
botStatusImage.alt = statusOn;
botStatusImage.title = statusOn;
}
}
}
}
}
}
}
}
Did someone from you know how it will work?
Thanks for your help!

I see a couple of problems with your code. First, the <i> element is used to apply italic formatting to text. It is not the HTML code for an icon or an image.
Secondly, you write botStatusImage.class.innerHTML, but the Element.class does not exist, and Element.className is a string. It does not have an innerHTML attribute. So, you could write botStatusImage.className = "new_class_name"; and this would be more correct.
You should then change the image source by calling botStatusImage.setAttribute('src', new_url), where you have set new_url to the new image location.
Check out the javascript reference for the Element class that is returned from document.getElementById: check this link
My recommendation, start simple, then make it complex.
First, try to get the icon to change without the AJAX request. Try writing a function like this:
function changeIcon( imageId, newUrl ){
var element = document.getElementById( imageId );
element.setAttribute( "src", newUrl );
}
Then test this function in the console by passing calling it with the URL's manually.
Once that works, don't change it! Next add the AJAX call, and when you have the Icon url from your server response, all you do is call the function that you already wrote and tested. That way you separate the AJAX code from the image update code and you can test them separately.
The key is smaller functions. Build the easy stuff first, and then call those easy functions from the harder functions. Once you know the easy function works well, it becomes much easier to find problems in the harder functions.

Trying to change button's contents each hit fails

Given the code :
<html>
<head>
<script src="jquery-2.1.0.min.js"></script>
Something...
</head>
<button id='flip' type='button'>Flip</button>
<script>
$('#flip').bind('click', function() {
var x = document.getElementById("flip").name;
if (x == 'Flip')
{
$(this).text('Flop');
}
else
{
$(this).text('Flip');
}
});
</script>
</body>
</html>
I'm trying to change the button each time it is clicked , but it doesn't work .
Any idea how to fix it ?
Much appreciated

There is no name attribute on your <button>, so you'll always get empty value. No need for document.getElementById because button is in this. Simply call text() without parameters to get current value:
var x = $(this).text();
Update
Here is demo in JsFiddler.

I would do something like this:
HTML:
<button id="flipflop">flip</button>
javascript:
var flip = true;
$("#flipflop").click(function(){
if(flip)
$("#flipflop").text("flop");
else
$("#flipflop").text("flip");
flip = !flip;
})
FIDDLE
edit: if you want to be really savvy, I would use the following line:
var flip = ($("#flipflop").text() === "flip");
Which automatically determines which way you need to flip (or is it flop?).

How can I dynamically add a class to 'body' using JavaScript only for the home page?

I added this to the head, but it's not working:
<script>
var xpathname = (window.location.pathname);
if (xpathname ==('/')) {
$('body').addClass('home');
}
</script>
The site is here: http://xotdr.unxpr.servertrust.com/
Volusion doesn't allow developers to code freely so there are a lot of workarounds that I need to implement, unfortunately.
Edit: I want the class to show only on the home page body.

Since you added this to the head you need to execute this snippet when body tag is available:
$(function() {
var xpathname = window.location.pathname;
if (xpathname == '/') {
$('body').addClass('home');
}
});

<script>
var bodyclass=document.createAttribute("class");
bodyclass.value="home";
document.getElementsByTagName("body")[0].setAttributeNode(bodyclass);
</script>

Give this a try
var b = document.getElementsByTagName('body')[0];
b.className += 'home';

I know it's a old post, but the question will remain useful.
var xpathname = (window.location.pathname);
var ndeBody = document.getElementsByTagName("body")[0];
if (xpathname ==('/')) {
ndeBody.classList.toggle("home");
}
else{
ndeBody.classList.toggle("home");
}

When I go to that URL you have syntax error:
Uncaught ReferenceError: x$ is not defined
e.g. you want to delete the x in x$('body').addClass('home');

Find specific div with RegEx and print content

I'm trying to pull some text from an external website using this script.
It works perfectly, but it gets the entire page. I want to take only the content inside a specific div with the class 'content'. The entire page is put inside the variable 'data', and then this function is created to strip some tags:
function filterData(data){
data = data.replace(/<?\/body[^>]*>/g,'');
data = data.replace(/[\r|\n]+/g,'');
data = data.replace(/<--[\S\s]*?-->/g,'');
data = data.replace(/<noscript[^>]*>[\S\s]*?<\/noscript>/g,'');
data = data.replace(/<script[^>]*>[\S\s]*?<\/script>/g,'');
data = data.replace(/<script.*\/>/,'');
return data;
}
How would I go about finding the div with the class 'content' and only viewing the content inside that?
UPDATE: Sorry about using RegExes — can you help me to get the content without using RegEx? So, this is my HTML file:
erg
<div id="target" style="width:200px;height:500px;"></div>
<div id="code" style="width:200px;height:200px;"></div>
<script src="http://code.jquery.com/jquery.min.js"></script>
<script>
$(document).ready(function(){
var container = $('#target');
$('.ajaxtrigger').click(function(){
doAjax($(this).attr('href'));
return false;
});
function doAjax(url){
if(url.match('^http')){
$.getJSON("http://query.yahooapis.com/v1/public/yql?"+
"q=select%20*%20from%20html%20where%20url%3D%22"+
encodeURIComponent(url)+
"%22&format=xml'&callback=?",
function(data){
if(data.results[0]){
var tree = string2dom(data.results[0]);
container.html($("div.content", tree.doc));tree.destroy();
} else {
var errormsg = '<p>Error: could not load the page.</p>';
container.html(errormsg);
}
}
);
} else {
$('#target').load(url);
}
}
function filterData(data){
return tree;
}
});
</script>

Try something like this:
var matches = data.match(/<div class="content">([^<]*)<\/div>/);
if (matches)
return matches[1]; // div content

try this:
<div\b[^>]*class="content"[^>]*>([\s\S]*?)<\/div>

Here try this :
<div[^>]*?class='content'[^>]*?>(.*?)</div>
Captured reference /1 will have your content. Although you shouldn't be doing this with regexes :)

this may help you:
var divtxt = match(/<div[^>]*class="content"[^>]>.*<\/div>/);
but it may stop at the wrong .
you should use jquery or prototype to make it a dom-object and use selectors to find the right div.
using jquery you would do something like:
var divtxt = $(data).find(".content").first().html();
remember to load the jquery library first.
