Use map

myArrayResult = myArray.map(function (el) {
   return el.id;  // if you want get id as Number, just add +el.id
})

Example

You could do

var myArrayResult = myArray.map(function (item) {
    return item.id;
}

Or if you don't have a true browser (ie. IE8 or less)

var myArrayResult = [];

for (var i = 0, l = myArray.length; i < l; i++) {
    myArrayResult.push(myArray[i].id);
}

myArray = [{'id':'73','foo':'bar'},{'id':'45','foo':'bar'}];

myArrayResult=[];
$.each(myArray,function(index,val){
     myArrayResult.push(val.id);
});
alert(myArrayResult);
