dynamic function

[rube]

There must be a simple solution, and I must be too tired to get it to work, but how does one call a function using a concatenated string?

I have a function:
SearchPage(){}

I have a string:
string="Search" + "Page";

I want to call the function!

Thanks.

Use a function literal and store it in a variable:

var searchPage = function(){};

then call the function with:

eval ("search+ "Page&quot()

Ooops ... make that:

eval ("search" + "Page&quot()

Sorry!

Thanks, man, I'll try that. I thought I had, but I gues I goofed it up. Had to check to see that I was on the right track.

Thanks again.

You can't evaluate a string. You should evaluate a variable containing a string. So you get:

FnString = "Search" + "Page";
Call(eval(FnString));

It is impossible to make anything foolproof because fools are so ingenious.

Sorry, electraboy, but what I typed above works ... I'm not careless enough to put up solutions that don't. I tested the above before I posted it, and it works all right. Although I see your point, and shall remember it for future reference
