问一个伪类作用域的问题。

Question

function GroupInfo(link, html, catalog){
    this._link = link;
    this._html = "<dl class=\"ob\">" + html + "</dl>";
    this._catalog = catalog;
    this._opt = 1;
    GroupInfo.prototype.setCatalog = function(catalog){
        this._catalog = catalog;
    };
    GroupInfo.prototype.getCatalog = function(){
        return this._catalog;
    };
    GroupInfo.prototype.getLink = function(){
        return this._link;
    };
    GroupInfo.prototype.getHtml = function(){
        return this._html;
    };
    GroupInfo.prototype.equla = function(groupInfo){
        return this._link == groupInfo.getLink();
    };
}上面是一个伪类，我经常在递归或者比较深的回调方法时后台会报没有方法错误，这是为什么。 js我没什么理论基础啊....

Answer 1

function GroupInfo(link, html, catalog){
    this._link = link;
    this._html = " <dl class=\"ob\">" + html + " </dl>";
    this._catalog = catalog;
    this._opt = 1;
｝
    GroupInfo.prototype.setCatalog = function(catalog){
        this._catalog = catalog;
    };
    GroupInfo.prototype.getCatalog = function(){
        return this._catalog;
    };
    GroupInfo.prototype.getLink = function(){
        return this._link;
    };
    GroupInfo.prototype.getHtml = function(){
        return this._html;
    };
    GroupInfo.prototype.equla = function(groupInfo){
        return this._link == groupInfo.getLink();
    };
这样写就对了~··
