圣杯。在选择更改时提交给控制器/操作

发布于 2024-12-17 02:38:03 字数 250 浏览 2 评论 0原文

我想提交一个表单来执行选择框更改的操作（当选择一个项目时，我需要更新另一个选择框，也许还有其他字段）。以下代码将表单提交到表单元素上定义的控制器/操作。

 <g:select onchange="submit()"/>

我如何将表单提交给自定义操作？我想在页面上放置一个隐藏的操作提交，并在选择框中选择一个项目时触发单击它，但希望有一种更优雅的方式。该项目使用jquery，因此原型库不可用。多谢！

原文

I would like to submit a form to an action on select box change (when an item is selected I need to update another select box and maybe other fields). The following code will submit the form to the controller/action defined on form element.

 <g:select onchange="submit()"/>

How could I submit the form to a custom action ?
I think to put a hidden action submit on the page and trigger a click on it when selecting an item in the select box, but hopping there is a more elegant way.
The project use jquery, so the prototype library isn't available.
Thanks a lot !

仅仅因为一个组合框发生更改就提交整个表单是一种不寻常的用例。通常，仅提交组合框的新值以下内容就足够了。

<g:form id="thisForm" action="yourFormAction">
    <g:select                       
        onchange="${remoteFunction(
            action:'yourOnChangeAction',
            update:'thisForm', 
            params:'\'thisInputField=\' + this.value' )}"
        value="${value}" 
        name="productDependencyType" 
        from="${values}" />
</g:form>

但是，如果您真的希望也提交所有其他表单字段，我想最好是有一个调度操作，并且您的输入框在提交到标准表单操作之前设置一些隐藏字段。隐藏的提交按钮很可怕:)

It is an unusal use-case to submit the whole form, just because one combo box is changed. Usually the following is sufficient submitting only the new value of the combo box.

<g:form id="thisForm" action="yourFormAction">
    <g:select                       
        onchange="${remoteFunction(
            action:'yourOnChangeAction',
            update:'thisForm', 
            params:'\'thisInputField=\' + this.value' )}"
        value="${value}" 
        name="productDependencyType" 
        from="${values}" />
</g:form>

However, if your REALLY want to have all other form fields to be submitted as well, I guess it would be the best, to have one dispatching action and your input box sets some hidden field before submitting to the standard form-action. Hidden submit buttons are scary :)
