input field value into link query string..

[jebster]

How would I take the value of a input field and put it into a links query string? Like google does when you have already typed a search term in the box then click on the "Image Search" link and such. Thanks

Not sure I understand what you mean...
On one page you have an input field and a hyperlink, and you want to add the user's input as a querystring to the hyperlinks href-part?

What Google does is simply what every webserver does when a form is posted (using method=get) to the server.

No not like that, go to googles main page and type in a search term but DON'T hit search, then hit the image search button and it will take the search term with to the image search page! :)

Hi Jebster,

The easiest way for you to copy what Google does is to have a look at the source code for their site.

I just had a look, and what it actually does is use Javascript to submit the search form to the Image search page when you click on the Image link - so it is not strictly a link, it is more like a submit button.

The value of "q" (the input field) is then used by the Image page just as any page uses a form variable received via a GET operation.

Is that allowed tho? Without their permission? Isn't that like stealing their code?

I'm not saying copy Google's JavaScript code letter for letter - it wouldn't work anyway unless you name everything on your site the same way.

All i'm saying is just look at how Google do it, see what HTML events and Javascript functions are used to achive the effect and then roll your own code.

Ok, thanks for the help! :)
