我有一个表格并保持所有字段的整洁，但并没有回答指令$（'＃txtConductorNew'）。val（''）;
不使用autocomplete属性的效果很好，它允许您清理jquery中的字段
我想知道我使用的CSS样式或JS的自动完成功能是否产生了某些不允许清理字段的问题。
HTML
<div class="form-group col-md-6 autocomplete">
<label>Conductor</label>
<input id="txtConductorNew" name="txtConductorNew" type="text" class="form-control">
</div>
CSS
* { box-sizing: border-box; }
body {
font: 16px Arial;
}
.autocomplete {
/*the container must be positioned relative:*/
position: relative;
display: inline-block;
}
.autocomplete-items {
position: absolute;
border: 1px solid #d4d4d4;
border-bottom: none;
border-top: none;
z-index: 99;
/*position the autocomplete items to be the same width as the container:*/
top: 100%;
left: 0;
right: 0;
}
.autocomplete-items div {
padding: 10px;
cursor: pointer;
background-color: #fff;
border-bottom: 1px solid #d4d4d4;
}
.autocomplete-items div:hover {
/*when hovering an item:*/
background-color: #e9e9e9;
}
.autocomplete-active {
/*when navigating through the items using the arrow keys:*/
background-color: #004D27 !important;
color: #ffffff;
