Question

i want to get value 13

how can i do this . basically i want to get all integers inside a string .

i tried with parseInt , but it returns int when the integer value is at the beginning of the string

Answer 1

您可以使用正则表达式 ：

var result = +text.replace(/\D/g, "");  // 13

Answer 2

var result=text.replace(/[^0-9]/g, ''); 

这将从您的字符串中删除所有非0-9值
