在Javascript中添加字符到一个字符串 [英] Add characters to a string in Javascript

问题描述

我需要在一个For循环字符中添加一个空字符串。我知道你可以在Javascript中使用concat函数来连接字符串。
var last_name =jones;
var name = first_name.concat（last_name）

工作。
任何想法如何做另一种方式？

我的代码：

  var text =; 
 for（var list in list）{
 text.concat（list [member]）; 
 
 $ / code> 




解决方案

  var text =; 
 for（var list in list）{
 text + = list [member]; 
} 
  




I need to add in a For Loop characters to an empty string. I know that you can use the function concat in Javascript to do concats with strings

var first_name = "peter"; 
var last_name = "jones"; 
var name=first_name.concat(last_name) 

but with my example it doesn't work. Any idea how to do it another way ?

my code :

    var text ="";
    for (var member in list) {
            text.concat(list[member]);
    }

解决方案

var text ="";
for (var member in list) {
        text += list[member];
}
