獲取位址列引數 - queryString(正規表示式版本)

獲取所有query string

function queryStringAll() {
    var reg = /(?:^|&)([^&]+)=([^&]+)(?=&|$)/g,
        args = {},
        qs = location.search || location.hash;
    qs = qs.slice(qs.indexOf('?') + 1);
    while (result = reg.exec(qs)) {
        args[result[1]] = result[2];
    }
    return args;
}

獲取指定name的query string

function queryString(key) {
    var reg = new RegExp('(?:^|&)' + key + '=([^&]+)(?=&|$)'),
        qs = location.search || location.hash;
    qs = qs.slice(qs.indexOf('?') + 1);
    return (result = qs.match(reg)) == null ? null : result[1];
}
