class Person
{
private $_category = 'human';
public function getCategory() {
return $this->_category;
}
}
$p = new Person();
$method = 'getCategory';
echo $p->$method();
So how to dynamically call a function in javascript? let's see the code:
Person = {
category : 'human',
getCategory : function() {
return this.category;
}
};
var method = 'getCategory';
Person[method].apply(Person);
That is it! actually, it is the same question as how to access an object's property and method dynamically in javascript. As to the apply method, check my last blog : http://hengrui-li.blogspot.com/2011/05/javascript-callback-function-scope.html
Well, the example shows how to dynamically call an object's method by name in javascript. So how to dynamically call a global function by name in javascript? Easy as well. Remember that everything in javascript is actually a property of the global object? Check this code:
callMe = function() {
alert('call me');
};
var method = 'callMe';
//in browser enviroment, window is the global object
window[method].apply();
