I am extremly new in javascript so please be patient.:) I have the following object
var obj= {
x: 0,
y: 0
};
I want to create a function that will take x,y from the user and store them to an array. So essensialy i want an array to store "obj" objects.
var arr = []; var i;
for(i=0; i<10; i++) { arr[i] = new obj(x, y); }
I am not even sure if i have started the correct way. So how can i fill my array with objects like this?
arr= [obj1, obj2, obj3, obj4];
Thank you..
Its is correct expect if u want to use the new operator use the function.
var obj = function(a,b) {
this.x = a;
this.y = b;
this.Sum = function(){
return this.x + this.y;
};
};
var arr = [],sumarr=[]; var i;
for(i=0; i<10; i++)
{
arr[i] = new obj(i,i+1);
sumarr[i] = arr[i].Sum();
}
For better understanding of the concept I recommend [http://zeekat.nl/articles/constructors-considered-mildly-confusing.html].
you can do something like t http://jsfiddle.net/naeemshaikh27/y5jaduuf/1/
var arr = []; var obj={};
$("#addToArray").click(function(){
obj.x= $("#x").val();
obj.y=$("#y").val();
arr.push(obj);
});
// create a constructor for our Obj
function Obj(x, y) {
this.x = x;
this.y = y;
}
/* fills array with those objects */
// create an array
var objs = [];
// fill the array with our Objs
for (var i = 0; i < 10; i++) {
objs.push(new Obj(i, i));
}
// and show the result
var msg = "";
for (var i = 0; i < objs.length; i++) {
msg += objs[i].x + ":" + objs[i].y + '\n';
}
/* now */
alert(msg);

If you're extremely new in javascript, I would advise you read good book about javascript. For example David Flanagan's: JavaScript The Definitive Guide There are many answers of the questions that you have now and will. It's best way I can suggest. Stackoverlow will not provide you much help on your current stage. That's my opinion
