JQuery EsayUI ComboBox 在chrome 报 An invalid form control with name='' is not focusable.

<form method="post" name="userForm" url="**"><input class="easyui-combobox" name="rId" required="true" data-options="valueField:'id',textField:'text',url:'url'" /><input type="submit" class="buttons" value="保存"/></form>

在chrome浏览器中会报:An invalid form control with name='' is not focusable.

将校验判断提前即可解决，修改如下

<form method="post" name="userForm" url="**"><input class="easyui-combobox" name="rId" required="true" data-options="valueField:'id',textField:'text',url:'url'" /><input type="button" class="buttons" value="保存" onclick="add()"/></form><script type="text/javascript">function add(){if ($('#userForm').form('validate')){$('#userForm').submit();}}</script>
