选择“搜索”按钮时，出现进度条

Question

我有这张表格，可以根据用户在表格上选择的内容搜索医生。

因此，当用户选择城市下拉框并单击搜索时，将在城市中显示医生。

但是，没有指示让用户知道表单正在获取结果。

我希望当用户单击表单右侧显示结果的搜索按钮时，将出现一个进度条，并将内容保留在进度条的背景后面

我的以下表格工作得很好，有一些小问题。 问题与用户输入邮政编码并决定按城市进行搜索有关，但确实会删除该字段，但是当我单击搜索时，结果不会更新。

 <script> $(document).ready(function(){ $('#zip').on("input",function(){ $('#city option[value=""]').prop('selected',true); }) $('#city').on("change",function(){ $('#zip').val(""); }) }) </script>

我想做以下事情，但使用引导程序：

 <div id="container" style="width:100%; height:5px; border:1px solid black;"> <div id="progress-bar" style="width:10%;background-color: green; height:5px;"></div> </div> <script> var width = 0; window.onload = function(e){ setInterval(function () { width = width >= 100 ? 0 : width+5; document.getElementById('progress-bar').style.width = width + '%'; }, 200); } </script> 

任何帮助，将不胜感激。

检查以下解决方案是否适合您，

 $(document).ready(function(){ $('#zip').on("input",function(){ $('#city option[value=""]').prop('selected',true); }); $('#city').on("change",function(){ $('#zip').val(""); }); $("#providerSearch").submit(function(e) { e.preventDefault(); var $progressbar = $('#progress-bar'); $progressbar.parent().removeClass("hidden"); var width = 0; setInterval(function () { width = width >= 100 ? 0 : width+5; $progressbar.css('width', width + '%'); }, 200); }); }); 

 .hidden { display : none; }
