Question

我有一个函数getActivityHP（），我会在页面加载时调用它。此函数使用某些数据对另一个test3.php页面进行ajax调用，这些数据最初将包含默认值。但是，只要我添加了ajax代码，该函数就会停止工作，就好像有错误一样。简单警报也不起作用！

   <script>
   $(document).ready( function(){
   alert("Welcome");// not working
   getActivityHP();
   }

 function getActivityHP() {
    $("#loading").show();
    alert("Hello"); // not working 
    var search = $("#search").val();
    var deployedon = $("#deployedon").val();
    var platform = $("#platform").val();
    var country = $("#country").val();
    var carrier = $("#carrier").val();

    $.ajax({
      type: "POST",
      url: "test3.php",
      data: {
        "action"                    :   "activity",
        "deployedon"                :   deployedon,
        "platform"                  :   platform,
        "country"                   :   country,
        "carrier"                   :   carrier
    },
    success: function(msg) {
        $("#loading").hide();
        $("#activity").html(msg);

    }
    error: function() {
    alert("An error occurred while processing file.");
  }
  });

  } 
 </script>
 In my test3.php I am doing:-

 $action=$_POST['action'];
 $deployedon=$_POST['deployedon'];
 $platform=$_POST['platform'];
 $carrier=$_POST['carrier'];
 $country=$_POST['country'];


 and then I am using echo to print these in my html!

Answer 1

存在语法错误。你错过了) -

$(document).ready( function(){
   alert("Welcome");
   getActivityHP();
});

在成功结束时遗失, -

success: function(msg) {
    $("#loading").hide();
    $("#activity").html(msg);
},

更新您的代码并尝试运行。

Answer 2

你在这里错过了一个逗号：

success: function(msg) {
    $("#loading").hide();
    $("#activity").html(msg);

}, // <--- This comma
error: function() {
alert("An error occurred while processing file.");

Jquery ajax（）没有按预期工作
