1.样式
代码如下:
<style type="text/css">
<!--
body{background:#fff}
.Menu {
position:relative;
width:180px;
height:120px;
z-index:1;
background: #EEE;
border:1px solid #666;
margin-top:-100px;
display:none;
}
.Menu2 {
position: absolute;
left:0;
top:0;
width:100%;
height:120px;
overflow:hidden;
z-index:1;
OVERFLOW-y:auto;
}
.Menu2 ul{margin:0;padding:0}
.Menu2 ul li{width:100%;height:25px;line-height:20px;text-indent:15px;
border-bottom:1px dashed #999;color:#333;cursor:pointer;
change:expression(
this.onmouseover=function(){
this.style.background="";
},
this.onmouseout=function(){
this.style.background="";
}
)
}
input{width:120px}
#List1,#List2{left:0px;top:103px;}
-->
</style>
2. html脚本
代码如下:
........省略常规脚本
<tr>
<th>汽车品牌名：</th>
<td>
<input type="text" id="generalBrandName" name="generalBrandName" value="${*.generalBrandName}" style="width:180px" data-validation-engine="validate[required]" <c:if test="${!empty carType.brandIdGeneral}"> disabled="disabled" </c:if> onfocus="showAndHide('List1','show');" onblur="showAndHide('List1','hide');"/>
<input type="hidden" id="brandIdGeneral" name="brandIdGeneral" value="${*.brandIdGeneral}" style="width:180px" />
<span class="required">必填*</span>
<div class="Menu" id="List1">
<div class="Menu2" id="ListLi1">
<%-- <ul>--%>
<%-- <li onmousedown="getValue('generalBrandName','宝马','brandIdGeneral','idx');showAndHide('List1','hide');">宝马</li>--%>
<%-- <li onmousedown="getValue('generalBrandName','奥迪','brandIdGeneral','idx');showAndHide('List1','hide');">奥迪</li>--%>
<%-- </ul>--%>
</div>
</div>
</td>
</tr>
........省略常规脚本
<tr>
<th>汽车厂商名：</th>
<td>
<input type="text" id="brandName" name="brandName" value="${*.brandName}" style="width:180px" data-validation-engine="validate[required]" <c:if test="${!empty carType.brandId}"> disabled="disabled" </c:if> onfocus="showAndHide('List2','show');" onblur="showAndHide('List2','hide');" />
<input type="hidden" id="brandId" name="brandId" value="${*.brandId}" style="width:180px" />
<span class="required">必填*</span>
<div class="Menu" id="List2">
<div class="Menu2" id="ListLi2">
</div>
</div>
</td>
</tr>
3.通过JS来实现ajax异步请求 根据输入的内容过滤
代码如下:
//页面加载的时候
jQuery(function($) {
if (navigator.userAgent.indexOf("MSIE") > 0) {
document.getElementById('generalBrandName').attachEvent("onPropertyChange", appendList);
