Javascript Functions

[iPokemon]

Here is an on-going thing that I'll be working on in JS OOP, just to learn the properties and stuff.


Array.prototype.has=function(v){
for(x=0;x<this.length;x++){
if(this[x] == v) return true;
}
return false;
}
Array.prototype.isArray=function(){
if(typeof(this) == "object"){
if(this instanceof Array){
return true;
} else {
return false;
}
} else {
return false;
}
}
Array.prototype.isEmpty=function(){
for(x=0;x<this.length;x++){
if(this[x] != "") return true;
}
return false;
}
Array.prototype.valAt=function(i){
return this[i];
}
Array.prototype.keyOf=function(v){
for(x=0;x<this.length;x++){
if(this[x] == v) return x;
}
return false;
}

Functions:

var testarray = ["test","test2"];
testarray.has("test"); //returns true
testarray.isArray(); //returns true
testarray.isEmpty(); //returns false
testarray.valAt(0); //returns test
testarray.keyOf("test"); //returns 0
