当在form元素中只有单个输入框时,回车会导致整个页面刷新
<form id="planQuery" style="margin:0; padding:0" queryFunction="getPlans" onsubmit="return false;">
<span class="property">
<label class="label" for="name">名称:</label>
<input type="text" id="name" name="name" class="input text easyui-validatebox-d" style="width:100px" data-options="validType:['text','length[1,20]'],required:false" enterQuery="true" autoQuery="true"/>
</span>
<a href="javascript:void(0)" id="btnSearch" class="easyui-linkbutton" data-options="iconCls:'icon-search',plain:false,disabled:false">查询</a>
</form>
