假设以下是我们的字符串-
var sentence = "My,,,,,,, Name,,,, is John ,,, Smith";
与split()
和一起使用正则表达式,join()
以删除多余的空格和逗号。以下是代码-
var sentence = "My,,,,,,, Name,,,, is John ,,, Smith"; console.log("Before removing extra comma and space="+sentence); sentence = sentence.split(/[\s,]+/).join(); console.log("After removing extra comma and space="); console.log(sentence)
要运行上述程序,您需要使用以下命令-
node fileName.js.
输出结果
在这里,我的文件名为demo133.js。这将产生以下输出-
PS C:\Users\Amit\JavaScript-code> node demo133.js Before removing extra comma and space=My,,,,,,, Name,,,, is John ,,, Smith After removing extra comma and space= My,Name,is,John,Smith
