如何从以“ |”分隔的字符串中获取最后一个文本

Question

I am having a string same like

a|b|c|d|e|....|n

I need to get the last item in this string in javascript. There may be n number of items in this string. Thanks in advance.

Answer 1

yourString.split('|').slice(-1)[0]

Answer 2

A bit verbose but probably the most straightforward way:

var str = 'a|b|c|e|f';
var arr = str.split('|'); // split into array
alert(arr[arr.length-1]); // get last element of the array

Answer 3

If your string is very long, you will want to avoid using .split('|') since that will create a new array with potentially many elements. I like .split('|') because it's unambiguous what you're trying to do, but if you want efficiency, you can use:

yourString.substr(yourString.lastIndexOf('|')+1)

(This will even work in corner cases like "abc" , "abc|" , and "|abc" , since lastIndexOf returns -1 if nothing is found.)

Answer 4

var str = "a|b|c|d|e|f|g";

var arr = str.split("|");
var last_item = arr[arr.length-1];

Answer 5

现在换个完全不同的东西！

/(?:\||^)([^|]*)$/.exec(str)[1]

Answer 6

Try it......

str='asfd|asdf|as|df|as|asdf|asf';
str.split('|').slice(b.length-1)[0]
