javascript中call()、apply()的區(qū)別

function track(o,m){
 var original =o[m];
 o[m] =function( ){
 console.log(new Date(),m);
 var results =original.apply(this,arguments);
 console.log(new Date(),m);
 return results;
 }
 }

<script>
var someObject = {
 myProperty:'Foo',
 myMethod:function (prefix,posfix) {
 console.log(prefix + this.myProperty + posfix);
 }
};
someObject.myMethod('<','>');//Foo

var someOtherObject = {
 myProperty:'Bar'
};
someObject.myMethod.call(someOtherObject,'<','>');//Bar
someObject.myMethod.apply(someOtherObject,['<','>']);//Bar
</script>
