$.extend 合并对象(处理可传入0个或多个参数)
function test(options){
$.extend({ },this.Default,options);
var v = this.Default || options;
alert(v.name);//传入打印'嘻嘻嘻嘻',不传入打印'呵呵呵'
}
test.prototype.Default = {
name:'呵呵呵'
};
new test({name:'嘻嘻嘻嘻'});
//js可传入对象,也可不传入,不传入时使用默认
function test1(options){
var defaults = { name: "foo" };
$.extend({ },defaults,options);
var v = defaults || options;
alert(v.name);//传入打印'嘻嘻嘻嘻',不传入打印'呵呵呵'
}
new test1({name:'ssss'});
