JavaScript 对象始终为 null

Question

这是我的代码:

myExt = {};
myExt.Panel = function (config){
    var d = document.createElement("div");
    /*Do something (a lot) with config and d here
    // a lot of code here
    */
    return
    {
        div:d,
        events:e,
        customattribs:ca
     };
}

这是我的来电者:

var p = new myExt.Panel({
    id:'parent',
    events:{
        onload:function(){
            alert("onload");
        }
    },
    //more configs
});

如果我这样做

console.log(p)

我得到空值。请帮我调试问题。

Automatic semicolon insertion已将函数的返回值从:

return { div: d, events: 3, customattribs:ca };

进入:

return;

如果您将要返回的值存储在变量中，然后返回该对象会更好:

var ret;
ret = {
    div: d,
    events: e,
    customattribs: ca
};
return ret;
