Is it possible to dynamically change the size of a canvas in javascript instead of specifying like below?

code:


 <body onload="draw()">
   <canvas id="canvas" width="600" height="400"></canvas>
 </body>
</html>

I got it working but not to my liking, I realized that the canvas is a bitmap so resizing makes it look like rear end.

Is there an easy way to find the index of an object in an array of objects in JS? I am trying to avoid an extra library to add in but if I have to I will (looking at underscore).

For example

code:


var foo = [{test:1,some:3,thing:4},{test:2,some:5,thing:6}];

How do I search for a specific index such as what is the index of {test:2,some:5,thing:6}? (which we know is 1 by looking).

IndexOf does not work for this correctly it would seem.

Yah I had to do a loop, would prefer a pre-made function, but I guess I will roll my own out of this, still easier than the standard functions.

code:

var test = [{name:"bob",id:5},{name:"dan",id:6}];

var check = {name:"dan",id:6};
for (var i = 0; i < test.length; i++) {
    var temp = _.isEqual(test[i],check); 
    if (temp === true) {
        alert(i);
    }
}
