拼接字符串并以逗号隔开

1.遍历数组并把数据拼成字符串以逗号进行分割。

a.前段js分割代码如下：

var ids="";var leibie = "";for(var i=0; i<currentRow.length; i++){ids += currentRow[i].id;leibie += currentRow[i].luyou_leibie;if(i !=currentRow.length-1){ids += ",";leibie += ",";}}

b. 后端java代码分割如下：

public static void StrArr(){String Str = "";int [] arr = {1,3,5,76,98,90,53,85,29};for (int i=0; i < arr.length; i++){Str += arr[i];if(i != arr.length -1){Str += ",";}}System.out.println("拼接字符串并以，分割："+Str);}
