法律研究用 JavaScript 正则表达式替换逗号？
假设以下字符串带有逗号 −
"My Favorite subject is," "My Favorite subject is, and teacher name is Adam Smith" "My Favorite subject is, and got the marks 89"
若要替换逗号，请使用 replace，并在其中使用正则表达式。下面是该代码 −
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"));
}若要运行上述程序，你需要使用以下命令 −
node fileName.js.
这里，我的文件名是 demo164.js。
输出
这将产生如下输出 −
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
