无法在ajax中发送多个变量

I have a button which when clicked I need to send two variables via a get request. If I just have one variable it works fine but as soon as I add the second one (str2) (called q) it doesnt do anything.

我有一个按钮,当点击时我需要通过get请求发送两个变量。如果我只有一个变量它工作正常,但只要我添加第二个(str2)(称为q)它不会做任何事情。

Script:

<script name="editresults">
    function editresults(str,str2) {
    if (str == "") {
        document.getElementById("mainpart").innerHTML="";
        return;
    } else { 
        if (window.XMLHttpRequest) {
            // code for IE7+, Firefox, Chrome, Opera, Safari
            xmlhttp=new XMLHttpRequest();
        } else {
            // code for IE6, IE5
            xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
        }
        xmlhttp.onreadystatechange=function() {
            if (xmlhttp.readyState == 4 && xmlhttp.status == 200) {
                document.getElementById("mainpart").innerHTML=xmlhttp.responseText;
            }
            $(document).ready(function() { $("#datepicker").datepicker({ dateFormat: 'dd-mm-yy', changeMonth: true,
            changeYear: true, yearRange: '1930:2015'}); });
        }
        xmlhttp.open("GET","editemployeedetailsform.php?id="+str+"&q="+str2,true);
               $('#editemployeedetailsform form').submit(function(){
          var data=$(this).serialize();
          // post data
          $.post('submit.php', data , function(returnData){
                      $('mainpart').html( returnData)
          })

          return false; // stops browser from doing default submit process
    });
        xmlhttp.send();
    }
} 
</script>

Code for button:

按钮代码:

<td><input type='button' value='Edit' onclick='editresults(<?php echo $surnames[$k]["employeeid"] ?>,<?php echo $q ?>)'></td>

It looks like it is not an problem with the ajax call, but with your mix of JavaScript and PHP. I guess the $surnames[$k]["employeeid"] is a integer, wich works without quotation marks ["] but the second parameter <?php echo $q ?> is probably a string an needs to be in quotation marks ["]

看起来它不是ajax调用的问题,而是你的JavaScript和PHP的混合。我猜$姓氏[$ k] [“employeeid”]是一个整数,它没有引号[“],但第二个参数 可能是一个需要用引号括起来的字符串[ “]

try this code for your button:

尝试使用此代码为您的按钮:

<td><input type='button' value='Edit' onclick='editresults(<?php echo $surnames[$k]["employeeid"] ?>,"<?php echo $q ?>")'></td>

more info: If the php interpreter adds a string like for example 'test' the result for the javascript interpreter my be onclick='editresults(1, test);' Which means that test would be considered a variable.

更多信息:如果php解释器添加了一个字符串,例如'test',那么javascript解释器的结果就是onclick ='editresults(1,test);'这意味着测试将被视为变量。
