牛魔王的故事

Aid.fn.extend 报错，Aid.fn = Aid.prototype，但是Aid不是函数呀，Aid.prototype是undefined。再Aid.fn = Aid.prototype的后面console.log(Aid)看一下

呼啦一阵风

Aid 是一个object, 返回 { isFunction : isFunctionCharacter }, 他又不是一个构造函数, 你怎么在他的原型里添加方法?Aid是模仿jquery做的一个方法吧? 那么var Aid = function() {&nbsp; &nbsp; var isFunctionCharacter = function(obj)&nbsp; &nbsp; {&nbsp; &nbsp; &nbsp; &nbsp; try {&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; if(typeof obj === "function") { //是函数&nbsp; &nbsp; 其中 FunName 为函数名称&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; console.log("is function");&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; } else { //不是函数&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; console.log("not is function");&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; }&nbsp; &nbsp; &nbsp; &nbsp; } catch(e) {}&nbsp; &nbsp; }&nbsp; &nbsp; return { isFunction : isFunctionCharacter };}// ();这里的立即执行应该去掉吧, 这样应该可以
