如何从纯JS Ajax转换为jQuery Ajax？

Question

我正在研究这个：

if (window.XMLHttpRequest) {
      xmlhttp = new XMLHttpRequest();
   }
   xmlhttp.onreadystatechange = function () {
      if (xmlhttp.readyState == 4 && xmlhttp.status == 200) {
         document.getElementById("txtuser").innerHTML = xmlhttp.responseText;
      }
   }
   xmlhttp.open("GET", "ajax.php?operation=get" + "&q=" + str, true);
   xmlhttp.send();

发送到 jquery...

我已有的代码：

$.ajax({
            type: "GET",
            url: "ajax.php",
            data: "operation=get" + "&q="+ str,
            success: function(){
                console.log('done');
            }
        });
    return false;

我做错了什么？

Answer 1

Maybe you are passing your data in the wrong way.. try with

data: { operation: 'get', q: str }
