Selecting Specific Lists

Question

I have the following code to return the libraries of my Sharepoint project:

function retornarLista() {
    collList = website.get_lists();

    context.load(collList);//, 'Include(TemplateType==109)'
    context.executeQueryAsync(onQuerySucceeded, onQueryFailed);
}

function onQuerySucceeded() {
    var listInfo = '';
    var listEnumerator = collList.getEnumerator();

    while (listEnumerator.moveNext()) {
        var oList = listEnumerator.get_current();
        listInfo += 'Title: ' + oList.get_title() +
            ' ID: ' + oList.get_id().toString() + '\n';
        $("#biblioteca").append("<option value='" + oList.get_id().toString() + "'>" + oList.get_title() + "</option>");
    }
}

function onQueryFailed() {
    alert("Failed");
}

I would like to return only the Image Libraries to transfer to a dropdown of select, but I haven’t been able to, someone can help ?

You are working with the Sharepoint JCOM library. The list object definition for this library can be seen at this link:

http://msdn.microsoft.com/en-us/library/office/jj245826(v=office.15). aspx

Note that there is property called baseTemplate.

When you create a list, you are indicating its base template (by your comment, SP.ListTemplateType.pictureLibrary).

Your code is almost complete, just missing now you go through all the lists you got in the query and check if the baseTemplate of them corresponds to the pictureLibrary template you use to create them. When matching is because the list is an image library :)

editing to include code: just adjust your code more or less like this:

/* .. snip .. */
while (listEnumerator.moveNext()) {
    var oList = listEnumerator.get_current();
    if (oList.get_baseTemplate() == SP.ListTemplateType.pictureLibrary) { // Eis o pulo do gato.
        listInfo += oList.get_title() + '\n';
    }
    /* .. snip .. */
}

By the way that SP.ListTemplateType.pictureLibrary is a constant value, 109. Living and learning, I didn’t know this template...
