execute a string in JavaScript

[Pesho318i]

Hi all,

I have a long string with JavaScript functions, e.g.
string = "document.write(\"Hello\")";

I'd like to execute this string in JavaScript. How can I do this?


thanks,
Pesho

With the dreaded eval function.
*(disclaimer: use of eval function is not recommended)

string = "document.write(\"Hello\")";
eval(string)

I'm going to bet there is a better way to do what you are wanting though.

Hi

string = "document.write(\"Hello\")";
[red]eval(string);[/red]

[ol]
[li]I would use variable name more different by the class name[/li]
[li]I would use [tt]eval()[/tt] only if no other solution is possible[/li]
[/ol]

Hi

Again monksnake... again...

You are incredibly fast. I am wondering how we, the other 9 in the MVP list, had the chance to get there anyway.

Sorry for interrupting you, but maybe you should consider updating your innerHTML instead of eval.

That's a very good point Diancecht.
