You can use combination of [substring()][1] and [lastIndexOf()][2] to get the last element.
您可以使用 [substring()][1] 和 [lastIndexOf()][2] 的组合来获取最后一个元素。
str = "~test content ~thanks ok ~fine";
strFine =str.substring(str.lastIndexOf('~'));
console.log(strFine );You can use [split()][4] to convert the string to array and get the element at last index, last index is length of array - 1as array is zero based index.
您可以使用 [ split()][4] 将字符串转换为数组并获取最后一个索引处的元素，最后一个索引是length of array - 1数组是基于零的索引。
str = "~test content ~thanks ok ~fine";
arr = str.split('~');
strFile = arr[arr.length-1];
console.log(strFile );OR, simply call pop on array got after split
或者，只需在拆分后的数组上调用 pop
str = "~test content ~thanks ok ~fine";
console.log(str.split('~').pop());回答by Niet the Dark Absol
Just use plain JavaScript:
只需使用纯 JavaScript：
var str = "This is ~test content ~thanks ok ~fine";
var parts = str.split("~");
var what_you_want = parts.pop();
// or, non-destructive:
var what_you_want = parts[parts.length-1];
