javascript - 正则表达式无法删除字符串/其他内容

Question

如何从 href 中删除该字符串并更新它？

示例网址:

"localhost:21088/WcfDataService1.svc/Clients?$top=20&$select=Name,Products/Name,ID,People/FirstName,Products/Price,People/LastName&$expand=People"

我正在尝试:

var stringToRemove = "Products" + "/";
var url = $("#qUrl").attr("href");
url = url.replace('/(' + stringToRemove + '\/\w+,)/g', '');
$("#qUrl").attr("href", url);

我想要什么:

"localhost:21088/WcfDataService1.svc/Clients?$top=20&$select=Name,ID,People/FirstName,People/LastName&$expand=People"

更新

请不要硬编码

如果您要删除所有Products/...,，则正则表达式为/Products\/.*?,/g

请注意，RegExp 是按原样编写的 - 没有用引号引起来。

var str = 'localhost:21088/WcfDataService1.svc/Clients?$top=20&$select=Name,Products/Name,ID,People/FirstName,Products/Price,People/LastName&$expand=People';

console.log(str.replace(/Products\/\w+,?/g, ''));

/**
 * Replace with variable string
 */

var key = 'Products'; // Come from external source, not hardcoded.
var pattern = new RegExp(key+'/\\w+,?', 'g'); // Without start and end delimiters!
console.log(str.replace(pattern, ''));
