用JavaScript Regex替换逗号？
假设以下是我们带逗号的字符串-
"My Favorite subject is," "My Favorite subject is, and teacher name is Adam Smith" "My Favorite subject is, and got the marks 89"
要替换逗号，请使用replace，并在其中使用正则表达式。以下是代码-
示例
const makingRegularExpression = /,(?=[^,]*$)/;
replaceComma("My Favorite subject is,");
replaceComma("My Favorite subject is, and teacher name is Adam Smith");
replaceComma("My Favorite subject is, and got the marks 89");
function replaceComma(values){
console.log(values, " ==== replaced by JavaScript ==== ", values.replace(ma
kingRegularExpression, " JavaScript"));
}要运行上述程序，您需要使用以下命令-
node fileName.js.
在这里，我的文件名为demo164.js。
输出结果
这将产生以下输出-
PS C:\Users\Amit\javascript-code> node demo164.js My Favorite subject is, ==== replaced by JavaScript ==== My Favorite sub ject is JavaScript My Favorite subject is, and teacher name is Adam Smith ==== replaced by JavaScript ==== My Favorite subject is JavaScript and teacher name is Ad am Smith My Favorite subject is, and got the marks 89 ==== replaced by JavaScript ==== My Favorite subject is JavaScript and got the marks 89
