Get query string values in JavaScript

我需要一个函数来读取查询字符串值吗？

如果我给出密钥，那么该方法应该返回相应的值。

请帮助..

Answer 1

试试这会有帮助

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

Answer 2

我总是使用以下内容，似乎可以正常工作

function urlParam(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];  
}

您只需致电urlParam("yourName");，它就会返回您的值;

Answer 3

使用getQuery（'mykey'）访问所需的查询;

function getQuery( key) {
        var hu = window.location.search.substring(1), gy = hu.split("&"), val;
        keyValue = {};
        for ( var i = 0; i < gy.length; i++) {
            val = gy[i].split("=");
            keyValue[val[0]] = val[1];
        }
        return keyValue[key];
    }
