模仿QQ邮箱，邮箱地址输入框

加入我上一篇修改过的jQuery.autocomplete.js 和css

页面代码：

<div>
	<div class="divContainer" style="width: 100%;border: 1px solid #ddd;overflow: auto;">
		<span style="font-weight: bold;float: left;padding-top: 3px;">发送：</span> 
		<div style="margin: auto;padding-top: 0px;font-size: 13px;">
			<div userid="" class="divInput" style="cursor: hand; margin-left: 1px; margin-top: 1px; float: left;"></div>
			<input style="border: 0;width: 10px;" type="text" id="txtToUser" name="txtMail" class="autocomplete"/>
			<input type="hidden" name="hidToUser" id="hidToUser" />
		</div>
	</div>
	<div class="divContainer" style="width: 100%;border: 1px solid #ddd;margin-top: 2px;background: #ffffcc;overflow: auto;">
		<span style="font-weight: bold;float: left;padding-top: 3px;">抄送：</span> 
		<div style="margin: auto;padding-top: 0px;font-size: 13px;">
			<div userid="" class="divInput" style="cursor: hand; margin-left: 1px; margin-top: 1px; float: left;"></div>

			<input type="hidden" name="hidCcUser" id="hidCcUser" />
		</div>
	</div>
<div>
