Hello members,

I have this understandable desire to figure out how does browsers remember what you typed in a textbox?

For instance: I type in "speed bikes" then click search. when i click on the back button the textbox still says "speed bikes". What causes this and most important can I do something with it.

I did a small test something like this

IF (textbox == "speed bikes")
{
document.write("speed bikes")
}

WEELLL,, I type in speed bike click search, go back and it doesn't do the document.write

No idea.......

it wont do the document.write because its using the cached version of the page, and its displaying it how you left it, with "speed bikes" in the textbox... (erm... thats what i think anyways...)

Yeah that's it; but it's pernitious - the data is there, and can be resubmitted, but if you try to read it through javascript, it returns an empty string!

But if you go

textBoxObj.value ="";

and you trigger it from <body onload, then the box will be auto-cleared when you press back.

can't you just use cookies?

Yeah I thought it had to do something with cache. I just find it unusal that the entered text stays there but the dynamic stuff don't even if you test the cached text.

I could use cookies but don't know how. I've read up and down this forum and see a repeat of "document.cookie". for some reason even if I copy the script provided by the member, it still doesn't work..
