Question

我正试图从一个看起来像这个'#somepage？id = 5'的网址中获取id我正在使用的功能似乎不起作用这个函数是：

function getParam(name) {
name = name.replace(/[\[]/, "\\\[").replace(/[\]]/, "\\\]");
var regexS = "[\\?&]" + name + "=([^&#]*)";
var regex = new RegExp(regexS);
var results = regex.exec(window.location.href);
if (results == null)
    return "";
else
    return results[1];
}

有没有办法可以修改或替换这个函数来从网址中提取id如上所述？

Answer 1

function getParameterByName(name) {
name = name.replace(/[\[]/, "\\\[").replace(/[\]]/, "\\\]");
var regex = new RegExp("[\\?&]" + name + "=([^&#]*)"),
    results = regex.exec(location.search);
return results == null ? "" : decodeURIComponent(results[1].replace(/\+/g, " "));
}
