如何获取ListView的连接项的ID？

Question

我在应用程序页面上有三个连接的ListView Web部件，我希望能够访问每个Web部件中选择的项目。这不是“复选框”中的“复选框”中的，而是将滤波器值传递给下一个Web部件的连接项。我试过

myWebPart.Connections // empty
myWebPart.FilterValue // null
myWebPart.ConnectionID // null

.

几乎我的网站部分的每个其他属性。没有办法获取正在连接的项目的ID？

Answer 1

I created three web parts connected together and filterable using Title:

Choose a color -> Choose a fruit -> View fruit details.

I created the following selector (jQuery required):

$('img[alt="Selected"]').parent().next().children('div.ms-vb');

Which returns an array of the selected elements which have an ID attribute. You could then do a simple each and do the work you want with each ID.

$('img[alt="Selected"]').parent().next().children('div.ms-vb').each(function(i){
   console.log($(this).attr('id'));
});
// will give you:
// 3 (Blue)
// 2 (Blueberry)

Shows up like this in Chrome console:

I think this will work as long as the you use the Title (linked to item) column in the web parts.

Answer 2

If you use JSLink instead, I think you can connect to the items in the ListView Web Part like this:

1. In a location of your choice (such as SiteAssets library of your site, or in _catalogs/masterpage), create new JavaScript file.
2. In the file, add the code below
3. In your web part, reference this JavaScript file in the JSLink setting, like ~/site/SiteAssets/news_ui.js

(function () {
 // Initialize the variables for overrides objects
 var overrideCtx = {};
 overrideCtx.Templates = {};

 overrideCtx.Templates.Fields = {
 'ID': { 'ItemID' : ctx.CurrentItem.ID } 
 };

 SPClientTemplates.TemplateManager.RegisterTemplateOverrides(overrideCtx);
 })();
