JavaScript代码

var $ = function(id)
{
return document.getElementById(id); 
}

var formInfo = location.search();
    formInfo = formInfo.substring(1, formInfo.length);

while (formInfo.indexOf("+") != -1)
{
    formInfo = formInfo.replace("+", " ");  
}



while (formInfo.indexOf("=") != -1)
{
    formInfo.replace("=", " "); 
}

formInfo = decodeURI(formInfo);
formInfo.replace("firstname", "");  
formInfo.replace("lastname", "");   
formInfo.replace("phonenumber", "");    
formInfo.replace("postalcode", ""); 
formInfo.replace("startingmoney", "");

var infoArray = formInfo.split("&");

var firstName = infoArray[0];
var lastName = infoArray[1];
var phoneNumber = infoArray[2];
var postalCode = infoArray[3]; 
var startingMoney = infoArray[4];

 $("playername").innerHTML = firstName + " " +lastName;
 $("playerinfo").innerHTML = phoneNumber + " " + postalCode;
 $("money").innerHTML = " $$" + startingMoney;

HTML代码

<div id="fireinfo">
<p id="playername"></p><br/>
<p id="playerinfo"></p>
<p id="money"></p>
</div>

使用此函数获取查询字符串值：

   function getQueryString(name) {
        name = name.replace(/[\[]/, "\\\[").replace(/[\]]/, "\\\]");
        var regex = new RegExp("[\\?&]" + name + "=([^&#]*)"), 
            results = regex.exec(window.location.search);

        return results == null ? "" : decodeURIComponent(results[1].replace(/\+/g, " "));
    };

    var firstname = getQueryString('firstname');
