Call a JavaScript function name using a string?
Property accessors can be used to access any object's properties or functions.
If the function is in the global scope, you can get it using the window object:
var myFunc = window[myFuncName];
This also works within the this
scope:
var myFunc = this[myFuncName];
... or this[myFuncName];
I have worked on this problem, as I needed a function like this. Here is my sandbox code, not thoroughly tested, but can be a startpoint for others. Note that there is one eval() in the code as I couldn't figure out how to bypass that step, maybe a javascript quirk and cannot be done in any other way. Let me know if there is a way to get rid of eval() here!
executeFunctionByName = function(functionName)
{
var args = Array.prototype.slice.call(arguments).splice(1);
//debug
console.log('args:', args);
var namespaces = functionName.split(".");
//debug
console.log('namespaces:', namespaces);
var func = namespaces.pop();
//debug
console.log('func:', func);
ns = namespaces.join('.');
//debug
console.log('namespace:', ns);
if(ns == '')
{
ns = 'window';
}
ns = eval(ns);
//debug
console.log('evaled namespace:', ns);
return ns[func].apply(ns, args);
}
core = {
paragraph: {
titlebar: {
user: "ddd",
getUser: function(name)
{
this.user = name;
return this.user;
}
}
}
}
var testf = function()
{
alert('dkdkdkd');
}
var x = executeFunctionByName('core.paragraph.titlebar.getUser', 'Ikon');
executeFunctionByName('testf');
Perhaps?
setTimeout ( "myFunc()", 1 );
