Parse Search String Into Get Variables
Aug 21, 2002
I feel like I have been repeating this code lately, so I cleaned it up and am gonna show it here. This function returns an array (with hash names) containing all the get variables.
function parseGetVars() {
var getVars = new Array();
var qString = unescape(top.location.search.substring(1));
var pairs = qString.split(/&/);
for (var i in pairs) {
var nameVal = pairs[i].split(/=/);
getVars[nameVal[0]] = nameVal[1];
}
return getVars;
}A simple page to test this looks like<html>
<head>
<title>Test</title>
<script>
function parseGetVars() {
var getVars = new Array();
var qString = unescape(top.location.search.substring(1));
var pairs = qString.split(/&/);
for (var i in pairs) {
var nameVal = pairs[i].split(/=/);
getVars[nameVal[0]] = nameVal[1];
}
return getVars;
}
</script>
</head>
<body>
<script>
var g = parseGetVars();
for (var i in g)
document.writeln(i+'='+g[i]+'<br>');
</script>
</body>
</html>

I have a wordpress site with dropdown menus that currently are working with jQuery, now the issue is when trying to dynamically update the menus and parsing it with json.parse. For some reason I am not getting any data back of the following code (if I try to alert (data) I just get a blank box).
function waitGoUpdate()
{
var $jQ = jQuery.noConflict ();
$jQ.ajax ({
[Code].....
and just print out the function, than I would get the data on screen. now if I was to access my php file directly than that fill will output an error due to missing plugins.. I guess that is just how wordpress sorta work.. but again I do get the info that i need by just printing out the function. Do anyone knows a work around for this? I am kinda pulling my hairs out.

I have a HTML string (which I retrieve from an XML file) and when I display it with
elm.firstChild.data = response;
Where 'response' is the HTML string, it will show the HTML tags non-parsed. How can I make it parse the HTML inside the string?

I have a string that contains n items. Each item start with a '@' and the
item itself does not contains the '@a'.
For example the string looks like: "@one@two@three@four"
I have to output this string as "one, two, three and four".
So in fact the first '@' can be removed, the next except the last replaces
by ", " and the last one by the word "and ".
Is there a simple way doing this?

I am looking for a javascript function that will parse a query string.
Parameters are passed in the url: url?a=3&c=5&etc
An array is returned that uses the variable name as the index.
array["a"]=3
array["c"]=5
etc.

I'm trying to parse a string from a URL and pass it as a parameter to another function. If that parameter meets certain conditions, I want hidden fields in my form to "unhide".
I am giving 3 usersr a specified url i.e. (http://DOMAINNAME.com?usr=uk or http://DOMAINNAME.com?usr=france) and based on that url, we'll parse the name and pass it as a parameter to a function. (i think i expressed that right??) Then we will display the proper shipping address depending on the parameter passed. My only problem now is, i'm horrible at writing regular expressions and programming in general. Do you or anyone else out there know of any good url parseing functions? I've been doing mostly project management throughout my career and never really got a chance to become fluent in javascript or programming for that matter.

I see that jQuery provides a function to turn an object into a set of URL query parameters: $.param({foo:"xxx", bar:"yyy"}) => "foo=xxx&bar=yyy" is there a function which does the opposite, i.e.parsing a query string into an object? The reason is that when I make an Ajax request, I want to take some parameters from the original page and include them in the new request, and modify others. I can get the original page's query string from location.search, which may contain, say, "?foo=xxx&bar=yyy" Now, suppose I want to submit an Ajax request with the same value of foo as the original page but a different value of bar, what's the cleanest way to do that? Remember that the original query string might have the two parts the other way round, i.e. "?bar=yyy&foo=xxx" If I need to write a function to split this myself, I know it's not a major undertaking, but I just wanted to see if I've missed something in the API.

I'm trying to parse a Json string received by $.getJSON(). I can receive the string but firebug gives me an "invalid label" error. I think it is because the string is an hash array with a number as first label, but I'm not sure. This is the string:
{"15":{"id":15,"x":0.4589937586135409,"y":
0.8324914620560137,"z":-0.9435707004102728,"rawData":"1256204002860 13
-442866538 18392602 647462767 314 1777206957 -1664784174 "}}
and this is the non-working code:

I have an XML document that is returned which has an element named html. Inside of that element is a block of HTML wrapped with CDATA tags. I can alert the html variable that i create and see it has all of the data inside of it. So I want to parse through and grab certain things now. I'm just trying to get the element to return it's id to me, even though I know it ... because I kept getting the following error with other code.[code]

I need to parse an HTML string received from an AJAX request. I wrote a function that places the HTML string into an unappended (not added) <div> , which opens the string up to the DOM hierarchy. However, when I try to access the elements of this <div> , I get an error in the console that says root.getElementById is not a function. This tells me that I can't access any of the child nodes.
Here is what my script looks like:
function parseHTML(html) {
var root = document.createElement("div");
root.innerHTML = html;
// The error console stops at this line

I am using javascript to search for the '*' character in a string (ie. 'username*:') but using search('*') does not work. How do I search for it since the search function takes a regexp argument and * messes that up?

this function is supposed to search a string for decimals and tell me how many of them it has found, but for some reason, it's not doing it right. since the "period" character is a special character in regular expressions,I went ahead and escaped it, but it's still doesn't work.
function ImprovedFormatAmount(ElementId)
{
var oElement = document.getElementById(ElementId);
var ElementValue = oElement.value;
var DecimalRegXp = /./g;
var OutputValue = ElementValue;
if (OutputValue.length > 0)
{alert (OutputValue.search(DecimalRegXp));}
}

I have a large string, but need to search for a specific character and replace it only if it is between two other items. Examplemystring would be something like this<parent><child1>1 & 2</child1><child2>1 & 2</child2><child3>1 & 2</child3></parent>I need to replace the & symbol in child2, but not 1 or 3. I am trying to figure out how to replace just any & signs in child2, but I need to leave them alone in child 1 and 3.I know I can do a replace(), but just not sure how to limit it to only the one I need

I would like to find some direction or help to solve an issue I have.I would like to find a way to search for a string of content on my webpage and return the string, or at least part of the string into the URL...Example of the content on my page:-----Welcome, John Adams Log OutWelcome to your own content, based on your settings provided. Feel free to download the content you need.Fairly straightforward. Now I would like to create a function that will look at the page and "copy" the string of content beginning with "welcome" and ending with "out"Next, I would like to remove the "welcome," and "log out" and have the name remain.Then, post the name into the URL to be passed onto the next page for me to use as more ersonalization/dynamically driven content; Such as:

I'm writing a piece of JS code that returns a result of true if the pattern appears in string as a substring (case sensitive) but would like to extend its functionality to returns true if all the individual characters of pattern appear in string (regardless of order).
