我正在尝试获取url查询字符串参数，并在if条件中进行比较。我在一个变量中得到这两个参数。如何同时检查这两个参数。有人能告诉我如何比较url的两个参数吗？例如：

http://www.xyz.com/?utm_campaign=freeship&utm_content=COUPON_CODE_HERE

我需要获得参数"freeship"answers"COUPON_CODE_HERE"请提供建议。

这是我的代码：

<script type="text/javascript">
$(document).ready( function(){
getUrlVars();
var param2 = [];    
if( param2 =("percentoff "  &&  "COUPON_CODE_HERE"))
{
    alert("hi");
}
 if( param2 = ("freeship "  &&  "COUPON_CODE_HERE"))
{
    alert("hello");
}

}); 
function getUrlVars()
    {
        var string1=["utm_campaign"];
        var string2=["utm_content"];
        var string1 = [], hash;
        var string2 = window.location.href.slice(window.location.href.indexOf('?') + 1).split('&');
        for(var i = 0; i < string2.length; i++)
        {
            hash = string2[i].split('=');
            string1.push(hash[0]);
            string1[hash[0]] = hash[1];

            param2=(hash[1]);
            //alert(hash[1]);

         }

       return string1;
}
</script>

试试这个

<script type="text/javascript"> 
    $(document).ready( function(){
        var params = getUrlVars();
        var utm_campaign = params["utm_campaign"];
        var utm_content = params["utm_content"];
        if( utm_campaign === "percentoff" && utm_content == "COUPON_CODE_HERE")
        {
            alert("hi");
        }
        if( utm_campaign === "freeship" && utm_content ===  "COUPON_CODE_HERE")
        {
            alert("hello");
        }
    });
    function getUrlVars() {
        var vars = [], hash;
        var hashes = window.location.href.slice(window.location.href.indexOf('?') + 1).split('&');
        for (var i = 0; i < hashes.length; i++) {
            hash = hashes[i].split('=');
            vars.push(hash[0]);
            vars[hash[0]] = hash[1];
        }
        return vars;
    }
</script>

根据您的要求，这些都是用于cookie操作的功能。

CreateCookie("cookie1", utm_campaign , 60);
//Creates client side cookie,
function CreateCookie(name, value, minutes) {
    var expires = "";
    if (minutes) {
        var date = new Date();
        date.setTime(date.getTime() + (minutes * 60 * 1000));
        expires = "; expires=" + date.toGMTString();
    }
    document.cookie = name + "=" + value + expires;
}
//Read cookie value
function ReadCookie(name) {
    var key = name + "=";
    var ca = document.cookie.split(';');
    for (var i = 0; i < ca.length; i++) {
        var c = ca[i];
        while (c.charAt(0) == ' ') c = c.substring(1, c.length);
        if (c.indexOf(key) == 0) return c.substring(key.length, c.length);
    }
    return null;
}
//Remove cookie
function RemoveCookie(name) {
    CreateCookie(name, "", -1);
}

使用document.URL或window.location.href可以在js 中获得链接

然后您可以使用match函数和regex:获得值

var url = document.URL;
url="http://xyz.com/?utm_campaign=freeship&utm_content=COUPON_CODE_HERE"; // remove this line on the website
var campaign = url.match('utm_campaign=([^&]*)');
var content = url.match('utm_content=([^&]*)');
console.log(campaign[1]); // index 1 is the match between the brackets (the wanted value) as 0 will be the whole matched string
console.log(content[1]);
//if you want you can assign the values to other vars:
// var utm_campaign = campaign[1],utm_content = content[1];
// ** here you can compare  campaign[1] & content[1] or utm_campaign & utm_content **
