只读，必填，combobox不可写、高度自适应

只读：

<input class="easyui-validatebox" type="text" id="txtCondNodeName" name="txtCondNodeName"
                                readonly="readonly" />

必填：

<input class="easyui-validatebox" type="text" id="txtOperatorValue" name="txtOperatorValue"  required="true" />

combobox不可写、高度自适应：

<select class="easyui-combobox" id="txtOperator" name="txtOperator" data-options="panelHeight:'auto'"  required="true"  editable="false">
                                <option value="=">=</option>
                            </select>
