jqeury发送请求问题

$("#submit").bind('click',function(){
$.ajax({
    type: "post",
    url: "<%=_c%>+/certBind/certbinding/binding.action",
    data: "text",
    success: function(msg){
  if(msg=="success"){
  alert("提交成功！");
   }else {
     alert("error！");
   }
   }
});
});

为什么这样写不能正常发送请求呢？我希望向服务端发送text文本 jquery
[解决办法]
url: "<%=_c%>+/certBind/certbinding/binding.action"，这里多了个"+",如果要用"+"来连接，这样写: url: <%=_c%>+"/certBind/certbinding/binding.action"试试

      $("#submit").bind('click', function () {
          $.ajax({
              type: "post",
              url: "<%=_c%>+/certBind/certbinding/binding.action",
              data: "text",
              success: function (msg) {
                  if (msg == "success") {
                      alert("提交成功！");
                  } else {
                      alert("error！");
                  }
              }
          });

          return false;//阻止表单提交，感觉你的这个submit按钮是type="submit"，这样会提交表单导致ajax不执行
      });
