我有这个表单，根据用户在表单上选择的内容搜索医生。
因此，当用户选择城市下拉框并点击搜索时，显示城市中的医生。
但是，没有迹象表明让用户知道表格正在取得结果。
我希望当用户点击表单右侧的搜索按钮时，会显示结果，会出现一个进度条，并将内容保留在进度条的背景后面
我有以下表格，工作得很好，有小问题。问题与用户输入邮政编码并决定按城市搜索相关，但确实会删除该字段，但是当我点击搜索时，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("");
})
})

我想做类似以下的事情，但使用bootstrap：
<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>
任何帮助都将不胜感激。

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;
