Parse HTML POST arguments from JavaScript

[BradleyRan]

Hi All,

I would like to pass some arguments to a JavaScript on another HTML page like:

http://www.my.site/MarkerList.html?Species=cattle&Chromosome=1

I see the "document.URL" contains the information I need and I just wondered if there was an easy or standard way to parse it out.

Thanks,

Randy

typically url contains
? = that means the data starts from here
& mean the next data element

And you usually have to parse it depending upon the way data is passed from the form.

hope this helps

When data is passed on the URL, it is using GET (not POST). I once wrote a script to automatically parse GET fields on the URL, using regular expressions, but unfortunately I've lost it now. The variable window.location.search holds the GET query as a string, starting with ? and delineated by &, as Khalid said.

I'm not sure if there are any pre-written scripts available out there, but you might be able to find one instead of writing your own code.

Thanks. I guess its easy enough:

url = document.URL.split("?")

args = url[1].split("&")
arg1 = args[0].split("=")
arg2 = args[1].split("=")

document.write(arg1[0] + " = " + arg1[1] + "<p>")
document.write(arg2[0] + " = " + arg2[1] + "<p>")

Now I just need to add my preprocessing stuff with a couple of if blocks.

args = url[1].split("&")
Remember that the semi-colon can also delimit a name/value pair.

args = url[1].split(/[&;]/)
