javascript 检测字符串中大于“>”和小于“<”的正则表达式

Regex that detects greater than ">" and less than "<" in a string

提问by Goenitz

I need a regular expression that replaces the greater than and less than symbol on a string

我需要一个正则表达式来替换字符串上的大于和小于符号

i already tried

我已经试过了

var regEx = "s/</</g;s/>/>/g"
var testString = "<test>"
alert(testString.replace(regEx,"*"))

My first time to use it please go easy on me :) Thanks

您可以使用正则表达式|像

For greater than and less than symbol.

用于大于和小于符号。

var string = '<><>'; string = string.replace(/[\<\>]/g,'*'); alert(string);

var string = '<><>'; string = string.replace(/[\<\>]/g,'*'); alert(string);

For special characters

对于特殊字符

var string = '<><>'; string = string.replace(/[&\/\\#,+()$~%.'":*?<>{}]/g,'_'); alert(string);

var string = '<><>'; string = string.replace(/[&\/\\#,+()$~%.'":*?<>{}]/g,'_'); alert(string);

Insert the regular expression in the code before class

在类之前的代码中插入正则表达式

using System.Text.RegularExpressions;

below is the code for string replace using regex

下面是使用正则表达式进行字符串替换的代码

string input = "Dot > Not Perls";
// Use Regex.Replace to replace the pattern in the input.
string output = Regex.Replace(input, "some string", ">");
