用最后一个逗号分隔字符串

Question

我在jQuery中有字符串。

var s = "Text1, Text2, Text,true";

我需要将这个变量拆分为两部分：

var s1 = substring(...); //after this s1="Text1, Text2, Text"
var s2 = substring(...); //after this s2="true"

你能帮我拆分变量吗？

Answer 1

var s="Text1, Text2, Text,true";
var lastIndex = s.lastIndexOf(",")

var s1 = s.substring(0, lastIndex); //after this s1="Text1, Text2, Text"
var s2 = s.substring(lastIndex + 1); //after this s2="true"

Answer 2

s1 = s.split(',');
s2 = s1.pop();
s1 = s1.join(',');

Answer 3

var index = s.lastIndexOf(",");
var first = str.substr(0, index );
var last = str.substr(index + 1);

或使用slice

var first = str.slice(0, index);
var last = str.slice(index +1);

Answer 4

尝试

var array = s.match(/(.*),(.*)/);
var s1 = array[1];
var s2 = array[2]

Answer 5

var s = "Text1, Text2, Text,true";
var n = s.lastIndexOf(",");

var s1 = s.substring(0, n);
var s2 = s.substring(n + 1);
