manipulating a string

[secretsquirrel]

hi,

i've got a URL with parameters in a hidden field which looks something like...

/cgi-bin/blahblah/page.w?param1=1&param2=2

i need to chop off the first part of the URL, so i'm left with

?param1=1&param2=2

can anyone recommend a way to do this, please?

previously i've had to do this with a URL in the address bar and it works using

document.location.search.split("w");

but if i do something similar with my hidden field it seems to replace all the 'w's in the string with a comma instead!

thanks in advance,

ss...

This should work:

var newStr = oldStr.substr(oldStr.indexOf('?'));

Hope this helps,
Dan

You also mentioned that:

This is easily explained if you were to understand that the .split("w") causes the passed string (document.location) to be converted into an array... with each element of the array delimited by the letter "w" (in this case).

You were most likely then alerting the returned result. This calls the .toString() method of the array... which returns a string with each element of the array delimited by a comma.

Hope this at least identifies that what you observed was not unexpected.

ok! i'm an idiot!

i've just discovered that the code i put above splits the string up and puts the bits in an array!

so the following seems to work...

var myArray = document.all.hiddenform.action.value.split(".w");
myParams = myArray[1];

thanks for your incredibly quick response though billyray!

Don't use document.all unless you want your pages to work ONLY on IE and not in any other browser.
