isObject判断

 

   本代码片段来自underscore

 

isObject:function(obj){
     return obj === Object(obj);
}

 

 

    补充一下tangram的代码设计：

 

//1.5.0
baidu.lang.isObject = function(source){
     return typeof source == 'function'  ||  !!(source && 'object' == typeof source);
}

 

//2.0.0.0
//调整了参数命名，个人不推荐原来的unknow
baidu.isObject = function(source){
    return typeof source === "function" || (typeof source === "object" && source != null);
}
