Question

I just wanted to ask if it is possible to take a string, which will always be constant and add a function’s name to it.
an example:

function modifyFunctionName(theFunc)
{
    var newFunc = "link" +theFunc;
    return newFunc;
}
//Somewhere in the HTML:
<input type='submit' value='button' onclick='modifyFunctionName(CheckLogin())'/>

So the modifyFunctionName will return linkCheckLogin().

EDIT: Sorry guys actually what I was exactly trying to do was this: https://gist.github.com/2371187

It technically is possibly, but you would have to use eval and that isn’t a good idea. What you could do is create an object and just store references to functions and it would work about the same way.

var obj={};

function addFunction(name,func){
  obj[name]=func;
}

function changeName(oName,nName){
  obj[nName]=obj[oName];
  delete obj[oName];
}

addFunction('test',function(){return 'hi'});
obj.test();//returns 'hi'
changeName('test','greet');
obj.greet();//returns 'hi'
