Jquery ajax调用抛出空JS异常?

标签: javascript jquery ajax

此功能适用于一个页面,但不适用于另一个页面。我添加了各种日志记录以尝试查找错误,但不能。破解页面上此代码的输出为:

[13:59:56.427] "here"
[13:59:56.428] "beforesend: /admin/test.html?server=eferbelly&port=24466&username=akilandy&password=vkjvkc9776A"
[13:59:56.428] "fileName=undefined"
[13:59:56.428] "lineNumber=undefined"
[13:59:56.428] "columnNumber=undefined"
[13:59:56.428] "here6"

告诉我它正在进入异常处理程序,完全跳过我的ajax()调用,但它并没有告诉我异常。

function test(server, port, username, password, spanId) {
  spanId = "#" + spanId;
  $(spanId).html("<img src='/images/ajax-small.gif'/>");
  console.log("here");
  try {
    $.ajax({
      dataType: "json",
      type: "GET",
      url: "/admin/test.html?server=" + server + "&port=" + port + "&username=" + username + "&password=" + password,
      success: function(json){
        console.log("here2");
        if (json.httpStatus == "200") {
          // Change the image to show success
          $(spanId).html("<img src='/images/accept.png' title='success'/>");
        }
        else {
          console.log("here7");
          // Change the image to show failure
          $(spanId).html("<span style='color:#b22222;'>" + json.httpStatus +"</span>&nbsp;<img style='vertical-align: middle;' src='/images/cancel.png' title='placeholder'/>");
        }
        console.log("here8");
        $(spanId).tooltip({ content: json.msg});
      },
      // Display the URL
      beforeSend: function(b,c,d) {console.log("beforesend: " + c.url);},
      error: function(b,c,d) {console.log("here5");}
    });
  }
  catch(e) {
    console.log(e);
    for (var i in e)
      console.log(i + "=" + i[e]);
  }
  console.log("here6");
}

我还可以做些什么来调试它?

更新:工作页面上的代码输出

以下是完全相同代码的输出,但在其工作的页面上:

[15:01:20.158] "here"
[15:01:20.159] "beforesend: /admin/test.html?server=eferbelly&port=24466&username=akilandy&password=vkjvkc9776A"
[15:01:20.159] "here6"
[15:01:21.661] GET https://localhost/images/accept.png [HTTP/1.1 200 OK 2ms]
[15:01:21.599] "here2"
[15:01:21.600] "here8"

所以它显然通过ajax调用飞行颜色。没有错误,没有。如何在页面上找不到问题?
