nope :)
won't work .
check the debugger :

Array.prototype.insertAt = function(i,e) { this.splice(0,0,this.splice(0,i),e, this.splice(i)); }; toto = new Array(); for(i=0;i<1000;i++) toto[toto.length] = "gffgfg"; toto.insertAt(60,"titi"); trace(toto[0] + "typeof : " + typeof(toto[0]));


splice method seems to return an object .

silly me, what was I thinking heh
splice does it alone

toto.splice(60,0,"titi")

ooops :)
you're right so ...
it's a bit useless but just for fun :
Array.prototype.insertAt = function(index,value)
{ this.splice(index,0,value);
};

it makes it more intutive :) I mean look at cyberfunk's 'invert a number':

Number.prototype.invert=function(){
return -this;
}

myNumber.invert()

when it would be easier to use

-myNumber

;)

This version [MX] will work on inserting arrays into the array - that is the array values of the array passed and not the array itself as one element


Array.prototype.insertArrayAt = function(index,ary){ this.splice.apply(this, [index,0].concat(ary)); return this; };
