常用工具判断-isString

 

判断源是否是string

 

这个api在YUI上的判断是这样

 

 

 

var L = Y.Lang || (Y.Lang = {});

/**
 * Determines whether or not the provided item is a string.
 * @method isString
 * @static
 * @param o The object to test.
 * @return {boolean} true if o is a string.
 */
L.isString = function(o) {
    return typeof o === 'string';
};

 

个人的凤凰lib还是采用类似的开源框架tangram的做法

 

/*
*isString-judge the source is or not string*
*@function*
*@param source*
*@return {boolean}*
*/
ZYC.lang.isString = function(source){
    return Object.prototype.toString.call(source) === "[object String]";
};
