Is it a bug? help me please!

[kingkong]

Javascrip code:

var input_id;
var patt=new RegExp(/(?<=id=")[\w\W]*?(?=")/);
input_id = patt.exec('<input id="input_1" value="">');

I cannt get the input id when I running on current page, but i can get it running local.

is this a zennoposter bug?

When executing Javascript code locally, it works not depending on browser and environment. In this case it's better process data using JS.
When executing Javascript code on current page, it works with DOM-objects on web-page loaded in browser. You should use it to operate with web-elements on page.

in this case, that's a test string. in my project, i need get some html source and find the id, and do something. so, i need executing code on current page.

In the Elements tree window you can find opjects on current web-page and process them in your script.

OP can I ask why do you use Javascript ?

thanks for your helps, I solved it by other ways, but I still think that's a bug.

I do not suggest to use JavaSctipt action unless there are no any alternatives. Gecko has problems with JS memory leaks.
