js面向对象编程遇到个问题，求解惑。。。
this.editUser = function (id) {
var user = this.getUserById(id);
var html = '<td><input type="checkbox" name="selectBox" value="'+user['id']+'" onchange="javascript:this.onChangeSelect('+user['id']+');"></td>';
html += '<td><input type="text" id="name_'+user['id']+'" name="name" value="'+user['name']+'"></td>';
html += '<td><input type="text" id="birthday_'+user['id']+'" name="birthday" value="'+user['birthday']+'"></td>'
html += '<td><input type="radio" value="M" name="gender_' +user['id']+'"';
if(user['gender'] == 'M') html += ' checked="checked"';
html += '> 男    <input type="radio" name="gender_'+user['id']+'" value="F"';
if(user['gender'] == 'F') html += ' checked="checked"';
html += '>女</td>';
html += '<input type="button" value="保存" onclick="javascript:this.saveUser('+id+');">  <input type="button" value="取消" onclick="javascript:this.cancelEditUser('+id+')"></td>';
document.getElementById('row_'+id).innerHTML = html;
}
html只认识window的对象，我要怎么改动才可以实现在html中调用这个对象中的方法呢？？？
[解决办法]
this.editUser = function (id) {
在上面这句之前定义 var window.aaaaa=this;
然后在onclick里面把this换成 aaaaa
[解决办法]
你那样用this对象为button对象。。创—OM的方法来添加，不能通过设置innerHTML，要不你就需要将你的实例变量保存为全局的，然后通过实例变量来调用，这样兼容性很差

    this.editUser = function (id) {
        var user = this.getUserById(id);

 /////////// /////////// /////////// /////////// ///////////
        var me = this; ///////////
        var tr = document.getElementById('row_' + id), td = tr.insertCell(0);
        var input = document.createElement('input');
        input.type = "checkbox";
        input.name = "selectBox"
        name.value = user['id']
        input.onchange = function () { me.onChangeSelect(user['id']); }

        var html = '<td><input type="checkbox" name="selectBox" value="' + user['id'] + '" onchange="javascript:this.onChangeSelect(' + user['id'] + ');"></td>';
 /////////// /////////// /////////// /////////// ///////////

        //下面的也按照上面的DOM方法来操作 
 
        html += '<td><input type="text"  id="name_' + user['id'] + '"  name="name" value="' + user['name'] + '"></td>';
        html += '<td><input type="text" id="birthday_' + user['id'] + '"  name="birthday" value="' + user['birthday'] + '"></td>'
        html += '<td><input type="radio"  value="M" name="gender_' + user['id'] + '"';
        if (user['gender'] == 'M') html += ' checked="checked"';
        html += '> 男    <input type="radio"  name="gender_' + user['id'] + '" value="F"';
        if (user['gender'] == 'F') html += ' checked="checked"';
        html += '>女</td>';
        html += '<input type="button" value="保存" onclick="javascript:this.saveUser(' + id + ');">  <input type="button" value="取消" onclick="javascript:this.cancelEditUser(' + id + ')"></td>';
        document.getElementById('row_' + id).innerHTML = html;
    };
