Javascript字符串拆分 - 在第二个逗号分割字符串

Question

根据此：C# String splitting - breaking string up at second comma

我该如何在JavaScript中执行相同操作？

Answer 1

var mystring = "test1, 1, anotherstring, 5, yetanother, 400"; 

var subString = mystring.slice(0,mystring.indexOf(',',mystring.indexOf(',')+1)); 

或者更漂亮：

var index = mystring.indexOf(',',mystring.indexOf(',')+1); 
var substring = mystring.slice(0,index); 

Answer 2

使用此...

var str="test1, 1, anotherstring, 5, yetanother, 400"; 
var n=str.match("([^,]*,[^,]*)(?:, |$)"); 
console.log(n); 

Answer 3

你也可以做到这一点没有正则表达式：

var splitAtSecondComma = function (str) { 
    var arr2 = str.split(","); 
    var arr1 = arr2.splice(0,2); 
    return [arr1.join(","), arr2.join(",")]; 
}; 

Answer 4

试试这个

function splitSecondComma(str) { 
    var arr = str.split(","), 
    l = arr.length, 
    arr2 = []; 
    for(i= 0; i < l; i= i+2) { 
    arr2.push(arr[i] + " " + arr[i+1]); 
    } 
    return arr2 
}
