grails - 获取remoteField以更新另一个字段

Question

我是Grails的新手，正在尝试Ajax。在我查看过的remoteField的所有示例中，结果呈现到屏幕上的纯div区域。我有这个工作，但我希望 Controller 的结果更新gsp字段之一中的值。当我如下图所示进行设置时，field元素消失了，仅由纯文本替换。有没有一种方法可以识别特定字段？

<div id="thisOne" class="fieldcontain ${hasErrors(bean: orderItemInstance, field: 'total', 'error')} required">
    <label for="total">
        <g:message code="orderItem.total.label" default="Total" />
        <span class="required-indicator">*</span>
    </label>
    <g:field name="total" value="${fieldValue(bean: orderItemInstance, field: 'total')}" required=""/>
</div>

<div id="input" class="fieldcontain">
    <label for="input">
        Input field
    </label>
    <g:remoteField name="input" action="recalc" update="thisOne"/>
</div>

Answer 1

您可以尝试remoteField的onSuccess事件，例如

<div class="fieldcontain ${hasErrors(bean: orderItemInstance, field: 'total', 'error')} required">
  <label for="total">
    <g:message code="orderItem.total.label" default="Total"/>
    <span class="required-indicator">*</span>
  </label>
  <g:field id="thisOne" type="text" name="total" value="${fieldValue(bean: orderItemInstance, field: 'total')}" required=""/>
</div>

<div id="input" class="fieldcontain">
  <label for="input">
    Input field
  </label>
  <g:remoteField name="input" action="test2" onSuccess="jQuery('#thisOne').val(data)"/>
</div>

注意:-thisOne现在是该字段的ID
