我有一个需要使用 ajax 的 spring-roo 应用程序，无论是 dojo 还是 jquery。在我的创建页面上，我需要其中一个输入字段是动态的（在一个字段中键入文本会在另一个字段中填充相同的文本）。默认情况下，Roo 使用 dojo 来验证这些输入字段。我试图使用 jquery 来处理这个问题，但到目前为止我还无法从该字段中获取值
创建.jsp
<script type="text/javascript">
<![CDATA[
$().ready(
function() {
$("#c_com_my_event_object_id_case").keypress(function() {
var str= $(this).val();
console.log(str);
});
});
]]>
</script>
<form:create id="fc_com_my_event_object" modelAttribute="object" path="/objects" render="${empty dependencies}" z="user-defined">
<field:input readonly="false" disableFormBinding="true" field="id.case" id="c_com_my_event_object_id_case" required="true" z="user-defined"/>
<field:input readonly="false" disableFormBinding="true" field="id.version" id="c_com_my_event_object_id_version" z="user-defined"/>
<field:input readonly="false" field="path" id="c_com_my_event_object_path" z="user-defined"/>
<field:input readonly="false" field="target" id="c_com_my_event_object_target" z="user-defined"/>
</form:create>
上述脚本中的 javascript 控制台记录“未定义”
