Grails GSP循环遍历索引，并对选定的行进行处理 [英] Grails GSP Loop through an index and do somthing with selected lines

问题描述

在Index-gsp中，我希望能够选择任意数量的行，然后通过单击链接将所有这些行发送到控制器进行处理，例如创建不同种类的新对象.

In an Index-gsp, I want to be able to select an arbitrary number of lines and then by clicking a link send all those lines to a controller for processing e.g. creating new objects of a different kind.

我不知道如何进行选择或如何在GSP中收集这些选定的行.可能的话，也许我应该在每行上使用一个复选框?

I've no idea how selection can be done or how to collect these selected lines in a GSP. Maybe I should use a checkbox on each line if that's possible?

这是使用修改后的index.gsp显示的产品列表. 每个产品线前面都有一个复选框. 我想要的是列出要检查的产品，然后将此列表发送给控制器.

It's a list of products which is displayed using a modified index.gsp. Each product-line has a checkbox in front. What I want is to make a list of the products that are checked an then transmit this list to a controller.

此index.gsp的一部分:

a part of this index.gsp:

        <li><a class="home" href="${createLink(uri: '/')}"><g:message code="default.home.label"/></a></li>
        <li><g:link class="create" action="create"><g:message code="default.new.label" args="[entityName]" /></g:link></li>
        <li><g:link class="create" action="createOffer"><g:message code="default.new.label" args="[entityName]" params="toOffer" /></g:link></li>
    </ul>
</div>
<div id="list-prodBuffer" class="content scaffold-list" role="main">
    <h1><g:message code="default.list.label" args="[entityName]" /></h1>
    <g:if test="${flash.message}">
        <div class="message" role="status">${flash.message}</div>
    </g:if>
    <table>
        <thead>
            <tr>
                <td> Välj</td>
                <td> ID</td>
            </tr>
        </thead>
    <tbody>             
        <g:each in="${prodBufferList}" status="i" var="prodBuffer">
            <tr class="${ (i % 2) == 0 ? 'even': 'odd'}">
                                        <td><g:checkBox name="toOffer" value="${prodBuffer.id}" checked="false"  /></td>
                                        <td>${prodBuffer.id}</td>

所以这不是普通形式，只是我想使用链接将其传输到控制器的列表.

So this not an ordinary form, just a list where I want to use a link to transmit it to the controller.

我是一个初学者，不知道如何做.

I'm a beginner and have no idea how to do it.

推荐答案

您可以使用javascript从页面收集所有必要的数据，然后将所有数据发送到控制器进行处理. 有很多方法可以做到这一点. 例如通过JQuery发送:

You can collect all necessary data from page using javascript, and then send all data to your controller for processing. There are a lot of ways to do it. For example send via JQuery:

<script>

//some code

var items = [1,2,3];

//some code

  $('#add-location').click(function () {
    $.ajax({
      type: "POST",
      url: "${g.createLink(controller:'myController', action: 'myControllerMethod')}",
      data: {items: items},
      success: function (data) {
        console.log(data)
      }
    });
  });
</script>
