在选择更改时显示/隐藏微调器 [英] Show/hide spinner on select change

问题描述

我正在使用 LoadAwesome ，我想知道如何显示Spinner div我在加载数据之前更改选择值. 当前，我正在使用AJAX请求来加载数据.

I'm using LoadAwesome and I want to know how can I show spinner div when I change select value before load the data. Currently I'm using AJAX requests to load the data.

简单说明:选定的更改->显示微调框->加载数据

Simple explanation: selected change -> show spinner -> load data

我已经尝试这样做，但是加载数据时没有旋转效果. :(

I'll already try to do this, but data is loaded without the spinner effect. :(

<select id="select_data">
  <option value="">Choose one..</option>
  <option value="1">Value 1</option>
  <option value="2">Value 2</option>
</select>
<div class="content">
  <div id="spinner">
    <div style="color: #79bbb5" class="la-ball-spin-fade la-2x">
      <div></div>
      <div></div>
      <div></div>
      <div></div>
      <div></div>
      <div></div>
      <div></div>
      <div></div>
    </div>
  </div>
  <br>
  <div id="text"></div>
</div>

$("#select_data").change(function() {
    // I want to show the spinner when I change select value before load the data -->
   // So before show this, I'll show the spinner and then, the text.
   $("#text").html(($("#select_data option:selected").text()));
});

推荐答案

使用此:

显示更改:

 $('.la-ball-spin-fade').hide();//hide by default  -can use css
    $("#select_data").change(function({     
    $('.la-ball-spin-fade').show();
        //trigger ajax
    });

在ajax成功隐藏它:

hide it at ajax success:

...
success:function(data) {
//other data manipulation;
 $('.la-ball-spin-fade').hide();
}
