tag UI Component

jQuery.telligent.evolution.ui.components.tag

UI Component which handles presentation of tagging behavior for content. Transforms the output from $core_v2_ui.Tag(), which is a <span class="ui-tag"></span> stub. The default implementation uses the evolutionInlineTagEditor plugin. Overrides can be provided at the theme level to present tagging differently.

Options

Data made available to instances of the component:

contenttypeid: (string) Content Type Id Guid
contentid: (string) Content Id Guid
tagtypeid: (string) Tag Type Id
urlformat: (string) URL containing a token named {tag} which, when replaced with a tag name, shows other content with the same tag
readonly: (boolean) When true, the component should not present editing controls
tags: Comma-separated list of tags currently applied to the content
selectabletags: Comma-separated list of optionally-selectable tags that may be presented to the user when not in read-only. These tags are already in use by other content.
configuration: Object of all other keys and values passed via the options dictionary to $core_v2_ui.Tag(), regardless of whether they have been pre-defined

Example

A barebones UI component override which would result in rendering a read-only message of 'Tagged: [tag], [tag], [tag], [etc]'.

$.telligent.evolution.ui.components.tag = {
    setup: function() {
    },
    add: function(elm, options) {
        var message = 'Tagged: ',
            renderedTagLinks = $.map(options.tags.split(','), function(tagName) {
                var tagUrl = options.urlformat.replace(/{tag}/, tagName);
                return  '<a href="' + tagUrl + '">' + tagName + '</a>';
            });

        $(elm).html(message + renderedTagLinks.join(', '));
    }
};

Default Implementation

For reference purposes or as the basis for an override:

(function($){

var formatTags = function(tagsList, urlFormat, elm) {
    var c = $(elm);
    c.html('');

    if (!tagsList) {
        return;
    }

    var first = true;
    $.each(tagsList.split(/,/), function(i, v) {
        var t = $.trim(v);
        if (t) {
            if (first) {
                first = false;
            } else {
                c.append(", ");
            }
            if (!urlFormat) {
                c.append(t);
            } else {
                c.append($('<a>').attr('rel','nofollow tag').attr('href', urlFormat.replace(/{tag}/g, $.telligent.evolution.url.encodePathComponent($.telligent.evolution.html.decode(t)))).text(t));
            }
        }
    });
};

$.telligent.evolution.ui.components.tag = {
    setup: function() {
    },
    add: function(elm, options) {
        var tagsContainer = jQuery('<span></span>');
        $(elm).append(tagsContainer);
        formatTags(options.tags, options.urlformat, tagsContainer);

        var editTags = null;
        if (options.readonly !== 'true') {
            editTags = $('<a href="javascript:void(0);" class="internal-link edit-tags"></a>');
            $(elm).append(editTags);

            editTags.evolutionInlineTagEditor({
                allTags: $.grep(options.selectabletags.split(','), function(item) { return item; }),
                currentTags: $.grep(options.tags.split(','), function(item) { return item; }),
                onSave: function(tags, successFn) {
                    var data = {
                        Tags: tags && tags.length > 0 ? tags.join(',') : '',
                        ContentId: options.contentid,
                        ContentTypeId: options.contenttypeid
                    };

                    if (options.tagtypeid) {
                        data.TypeId = options.tagtypeid;
                    }

                    $.telligent.evolution.put({
                        url: $.telligent.evolution.site.getBaseUrl() + 'api.ashx/v2/contenttags.json',
                        data: data,
                        success: function(response) {
                            formatTags(data.Tags, options.urlformat, tagsContainer);
                            successFn();
                        }
                    });
                }
            });
        }
    }
};

}(jQuery));
