Use jQuery to replace all strings. Use jquery to replace strings.

Everyone knows that jquery has a replace method that can replace "" in a string with any character, but only one replacement can be used. If there are multiple occurrences, only regular expressions can be used for processing.

Var title = "aaa"; var re = new RegExp ("", "g"); // define a regular expression // The first parameter is the content to be replaced, the second parameter "g" indicates replacing all (global ). NewTitle = title! = Null? Title. replace (re, "_"): title; // arithmetic operation

The last code is to replace "" With _ according to the re regular expression rules _

In addition, there is a regular expression testing tool on the front-end. Recently, I am still learning regular expressions. Come on !!!
