Wie bekomme ich Wurzel von Variationen von Client OM (JS)?

Question

lassen Sie sagen, ich habe Unterseiten auf meiner "Hauptseite" (das nicht root der Site-Sammlung ist), wie Home-Sub-Site, über Kontakt.Die "Hauptseite" ist eigentlich die Sprachvariation eines anderen Standorts.In anderen Worten habe ich so Struktur wie dieses generasacodicetagpre.

Was ich gerne tun würde, ist so etwas wie folgt generasacodicetagpre.

edit: Frage ist für SharePoint 2013.

It actually depends what version of SharePoint is used.

How to retrieve Variation Labels via CSOM?

Since variations labels are stored in a Hidden List (MOSS 2007, SPS 2010/2013) we could retrieve it via CSOM (ECMAScript) as demonstrated below:

function getVaritationLabels(OnSuccess,OnError){
    var ctx = SP.ClientContext.get_current();
    var rootWeb = ctx.get_site().get_rootWeb();
    var webProperties = rootWeb.get_allProperties(); 
    ctx.load(rootWeb); 
    ctx.load(webProperties);
    ctx.executeQueryAsync(
      function() {
         var varLabelsListId = webProperties.get_item('_VarLabelsListId');

         var labelsList = rootWeb.get_lists().getById(varLabelsListId);
         var labelItems = labelsList.getItems(SP.CamlQuery.createAllItemsQuery());

         ctx.load(labelItems);
         ctx.executeQueryAsync(
            function() { 
               var variationLabels = [];

                var e = labelItems.getEnumerator();
                while (e.moveNext()) {
                    var labelItem = e.get_current();
                    variationLabels.push({
                        'IsSource': labelItem.get_item('Is_x0020_Source'),
                        'Language': labelItem.get_item('Language'),
                        'Locale': labelItem.get_item('Locale'),
                        'Title': labelItem.get_item('Title'),
                        'TopWebUrl': labelItem.get_item('Top_x0020_Web_x0020_URL')
                    });  
                }

               OnSuccess(variationLabels);
            },
            OnError
         );

      },
      OnError
    );
}

The function returns an array of Variation Label entries:

IsSource - Determines whether the Variation Label is set as the source label

Language - Returns the Language of the Variation Labe

Locale - Returns the Locale of the Variation Label

Title - Returns the title of the Variation Label, which is the unique string identifier of the label

TopWebUrl - Returns the URL of the top Publishing Web of the variation hierarchy of this label.

Example: How to determine Variation Home?

Assume the following variation labels have been configured

where

en-us Variation Label corresponds to Variation Home (Is Source parameter is set to True)

then the following function will return the Url of the variation hierarchy:

function getVariationLabelSourceUrl()
{
    var sourceUrl = '';
    getVaritationLabels(
      function(variationLabels){
          for(var j = 0; j < variationLabels.length;j++){
              var variationLabel = variationLabels[j];
              if(variationLabel.IsSource){
                  sourceUrl = variationLabel.TopWebUrl.get_url();
                  break;
              }
          }
          console.log('Variation Label Source Url: ' + sourceUrl);
      },
      function(sender,args) {
        console.log('An error occurred: ' + args.get_message());
      }
    );
}
