Re: String question

Possible solution:

Copy and save as testme.html

<HTML>

<SCRIPT>

//Get the full URL

theFullURL=docu ment.location.h ref;

document.write( "The Full URL:"+theFullUR L+"<BR>");

//Index the ID part of string

id=theFullURL.i ndexOf("id=");

document.write( "Index of URL:<B>"+id+"</B><BR>");

//Get the following string from index

//(+2 to get rid of 'id=')

idVal=theFullUR L.substring(id+ 2);

document.write( "ID:<B>"+idVal+ "</B>");

</SCRIPT>

<HTML>

When you run the HTML in explorer add your other values.

(i.e

ORIGINAL:

C:\test\testme. html

RUN Like:

C:\test\testme. html?action=sho wnesitem&id=125

)

Worked for me!

If it's always "id=", just use:

(new RegExp("id=(\\d +)")).test(wind ow.location.sea rch);
var id = RegExp.$1;
alert(id);

window.location .search might look something like:
"?param=blah&id =123&somethinge lse=something" so:

(new
RegExp("id=(\\d +)")).test("?pa ram=blah&id=123 &somethingelse= something");

var id = RegExp.$1;
alert(id); // alerts "123" which is correct

The nice thing about using (new RegExp()).test( ); var x =
RegExp.$1; is that you always either get the string you are looking
for, or you get an empty string. It never causes an error, it never
results in a null value. The *only* thing to be aware of is if you
were looking for something other then numbers, then you need to
make sure you don't pick up the entire query string:

(new RegExp("param=( .[^&]+)")).test(wind ow.location.sea rch);

Lastly, if you're looking for a lot of values on the query string,
this mechanism is better replaced with something that retrieves all
the key/value pairs as an object's properties/values. And this
mechanism doesn't support multiple same named items on the query
string (although it could be modified to).
