JavaScript string.format

//string.format
        String.prototype.format=function(){
            var e = this, f = arguments.length;    
            if (f > 0) {        
                for ( var d = 0; d < f; d++) {            
                    e = e.replace(new RegExp("\{" + d + "\}", "g"), arguments[d])        
                }    
            }    
            return e
        };

JavaScript 实现字符串占位。

String.prototype.format =function(){

var e =this, f = arguments.length;

if(f >0){

for(var d =0; d < f; d++){

e = e.replace(newRegExp("\{"+ d +"\}","g"), arguments[d])

}

}

return e

};

 

var msg ="我爱我的家人{0}，我的家人也爱我{1}";

var a = msg.format("xixi...","haha...");

alert(a);//我爱我的家人 xixi... ，我的家人也爱我haha...
