Retrieving a QueryString

[johnsimpson]

Hi guys, need a little help.

Basically i have a HTML list menu (drop down list) and on selection the user will be directed to a specific page.

In this link i am including a querystring ?state=New York

When the user is taken to the appropriate page i am retrieving the querystring and using it as a title for the page. The problem is its displaying as New%20York. So its replacing the space with %20.

How can i remove this from the querystring? so it displays properly?

thanks
John

Use the "unescape" function:

alert(unescape('your%20string'));

hope this helps,
Dan

Cheers Dan. but where will i put this?

 

[johnsimpson]

Dan, this works perfectly, thanks very much, you saved me a lot of time!!

 

[johnsimpson]

next question, is how can i preselect the appropriate list item by sending a querystring?

So i want to select for example Manchester from a dropdown list, this will then redirect to contact.html?=New%20York and i want it to select the option New york from the drop down list menu on the target page

thanks

That depends on many things.

Personally, I'd do all this server-side, as doing it client-side will mean people with no JavaScript enabled will not be able to use your site.

Try adding this line to your function that's putting "New York" into the page's title:

document.forms['form_name'].selects['select_name'].selectedindex = 'New York';

...if that doesn't work, post your code (JavaScript you're parsing the URL with, and HTML for the form) here & maybe one of us will catch the error.

Rob - that won't work for 2 reasons:

1. selectedIndex has an uppercase "i", and JS is case-sensitive, and
2. selectedIndex holds an integer value, not a string.

Thank you for pointing that out Dan;

I think this script will do it though:

var num = 0;
var Found_iT = false;
var FoO = document.forms['form_name'].selects['select_name'];
while((num < FoO.options.length) && (!Found_iT))
{
 if(FoO.options[num].value == 'New York')
 {
  FoO.selectedIndex = num;
  Found_iT = true;
 };
 num++
};

I hope this helps;
