如何设置 grails 导出插件的 export:formats 元素中的 params 属性值

发布于 2024-11-10 18:17:25 字数 668 浏览 0 评论 0原文

我已经安装了 grails 导出插件。它有一个元素 export:formats ，它采用 params 值作为属性。我想知道如何将其他元素的值设置到此 params 属性上，以便我的控制器操作可以使用它。

<div id="exportDetail">
     <g:select name="reportType" from="${['Daily', 'Weekly Hour', 'Weekly Day']}" ></g:select><br/>
     <g:datePicker name="reportStartDate" precision="hour"></g:datePicker><br/>
     <g:datePicker name="reportEndDate" precision="hour"></g:datePicker><br/>
     <export:formats action="exportRollup" formats="['csv', 'excel', 'ods', 'pdf', 'rtf', 'xml']" params="[**how to pass select, datepicker stuff here to controller**]"/>
</div>

I have installed the grails export plugin. It has an element export:formats which takes a params value as attribute. I want to know how to set values from other elements onto this params attribute so that it is available to my controller action.

<div id="exportDetail">
     <g:select name="reportType" from="${['Daily', 'Weekly Hour', 'Weekly Day']}" ></g:select><br/>
     <g:datePicker name="reportStartDate" precision="hour"></g:datePicker><br/>
     <g:datePicker name="reportEndDate" precision="hour"></g:datePicker><br/>
     <export:formats action="exportRollup" formats="['csv', 'excel', 'ods', 'pdf', 'rtf', 'xml']" params="[**how to pass select, datepicker stuff here to controller**]"/>
</div>

您提供给 taglib 的参数只会影响 Grails 呈现的链接。如果您希望链接包含在页面渲染后更改的参数（例如日期选择器选择的值），那么您需要使用 Javascript。这是一个粗略的示例：

 $('.menuButton a').click(function() {
     var target = this.href + '&reportStartDate=' + $('#reportStartDate').val();
     window.location.href = target;
     return false;
 });

理想情况下，您的导出按钮将提交包含日期选择器的表单，并且您不需要使用 Javascript。您必须编写自己的格式标签库才能做到这一点。这将帮助您开始：

在您的项目中创建一个新的标记库。给它namespace = 'export'，这样它就可以覆盖插件的标签。将 formats 标记从 ExportTagLib 复制到新标记库。
将标记更改为提交按钮： input(type: 'submit', name: 'format', value: format)
如果您想要图形按钮，改用这个： input(type: 'image', name: 'format', value: format, src: g.resource(plugin: 'export', dir: 'images/skin', file: format + '.png'))
您现在需要在 GSP 中的标记周围添加一个
标记。

您将无法再在控制器中使用 params.extension ，但从格式中找出文件扩展名并不难。

The params you give to the taglib will only affect the link rendered by Grails. If you want the link to contain params that change after page rendering, such as the values selected by the datepickers, then you need to use Javascript. Here's a rough example:

 $('.menuButton a').click(function() {
     var target = this.href + '&reportStartDate=' + $('#reportStartDate').val();
     window.location.href = target;
     return false;
 });

Ideally, your export buttons would submit a form containing the datepickers, and you would not need to use Javascript. You would have to write your own formats taglib to do that. This'll get you started:

Create a new taglib in your project. Give it namespace = 'export', so it can override the plugin's tags. Copy the formats tag from ExportTagLib to your new taglib.
Change the <a> tag to a submit button: input(type: 'submit', name: 'format', value: format)
If you want graphic buttons, use this instead: input(type: 'image', name: 'format', value: format, src: g.resource(plugin: 'export', dir: 'images/skin', file: format + '.png'))
You'll now need a <form> tag around your <export:formats> tag in your GSP.

You won't be able to use params.extension in your controller anymore, but it's not hard to figure out the file extension from the format.
