jq ashx获取不得到值

Question

<script language="javascript" type="text/javascript">          $(document).ready(function(){              $("#Button1").click(function(){                         $.ajax({                   type:"post",                   dataType:"text",                    url:"Handler.ashx",                   data:"username"+$("#Text1").val(),                   success:function(msg){                   alert(msg);               }              })              })          })              </script> ashx:  public void ProcessRequest (HttpContext context) {        context.Response.ContentType = "text/plain";        string name = string.Empty;        if (context.Request["username"] != null)        {             name = context.Request["username"].ToString();        }        context.Response.Write(name);    }   在这里我怎么获取不到username的值呢？

Answer 1

data:"username"+$("#Text1").val()=>data:{"username:"+$("#Text1").val()}

Answer 2

data:"username"+$("#Text1").val()   写错了

 

改为：data:"username="+$("#Text1").val(),
