How to read a parameter from another page? 1

[royboy75]

Hello,

I am referring to another html page using the standard link tag: <a href="intro.html"...
Suppose I am transferring a parameter to this page, like this: <a href="intro.html?myVal=hello"...
Is it possible to read it from the intro.html file using client side technologies, such as plain html or javascript?

Hi

You find the parameters in the [tt]location[/tt] object's [tt]search[/tt] property. But you will need to split it.

[b]var[/b] par=[b]new[/b] Array();
[b]var[/b] parStr=location.search.replace(/^\?/,[i]''[/i]).split(/[&;]/);
[b]for[/b] (i=0;i<parStr.length;i++) {
  [b]var[/b] part=parStr[i].split(/=/,2);
  par[part[0]]=part[1];
}

And after the above you will have the parameters in the par [tt]Array[/tt].

Hi

Oops. And if you need special characters too, then change the last line to decode eventual URLEncoded entities :

  [gray]...[/gray]
  par[unescape(part[0].replace(/\+/g,[i]' '[/i]))]=unescape(part[1].replace(/\+/g,[i]' '[/i]));
}
