在查询$.extend方法时看到的一个列子特别好，记录下来。可以用来解析json串到数组
<!DOCTYPE html>

<div id="log"></div>

var object1 = {
apple: 0,
banana: {weight: 52, price: 100},
cherry: 97
};
var object2 = {
banana: {price: 200},
durian: 100
};
/* merge object2 into object1, recursively */
$.extend(true, object1, object2);
var printObj = typeof JSON != "undefined" ? JSON.stringify : function(obj) {
var arr = [];
$.each(obj, function(key, val) {
var next = key + ": ";
next += $.isPlainObject(val) ? printObj(val) : val;
arr.push( next );
});
return "{ " + arr.join(", ") + " }";
};
$("#log").append( printObj(object1) );
</script>
