Display attachments using JSLink in SharePoint

May 30, 2017 / Kannan / 0 Comments

Recently I had a requirement where the customer wanted to show the actual attachment’s URL in the list view instead of default Icon. Following JSLink code will help to do that.

(function () {
    var linkFiledContext = {};
    linkFiledContext.Templates = {};
    linkFiledContext.Templates.Fields = {
        "Attachments": { "View": OverrideAttachmentFieldRendering }
    };
    SPClientTemplates.TemplateManager.RegisterTemplateOverrides(linkFiledContext);
})();

function OverrideAttachmentFieldRendering(ctx) {
    var itemId = ctx.CurrentItem.ID;
    var listName = ctx.ListTitle;
    return GetAttachments(listName, itemId);
}

function GetAttachments(listName, itemId) {
    var url = _spPageContextInfo.webAbsoluteUrl;
    var requestUri = url + "/_api/web/lists/getbytitle('" + listName + "')/items(" + itemId + ")/AttachmentFiles";
    var htmlString = "<span style='white-space: nowrap;'>No attachment(s)</span>";

    $.ajax({
        url: requestUri,
        type: "GET",
        headers: { "ACCEPT": "application/json;odata=verbose" },
        async: false,
        success: function (data) {
            for (var i = 0; i < data.d.results.length; i++) {
                htmlString += "<a style='white-space: nowrap;'  href='" + data.d.results[i].ServerRelativeUrl + "'>" + data.d.results[i].FileName + "</a>";
                if (i != data.d.results.length - 1) {
                    htmlString += "<br/>";
                }
            }
        },
        error: function (error) {
            console.log("An error occured while fetching attachment details. Details: " + JSON.stringify(error))
        }
    });

    return htmlString;
}

Change SharePoint’s “there are no items to show in this view” message

May 25, 2017 / Kannan / 0 Comments

When a list has not data to be shown in the view, we see the following message.

There are no items to show in this view of the “<ListName>” list.

The following JSLink script helps to change this message.

(function () {
    var overrideCurrentContext = {};
    overrideCurrentContext.Templates = {};
    overrideCurrentContext.Templates.OnPreRender = changeNoListItemMessage; //OR overrideCurrentContext.OnPreRender = changeNoListItemMessage;
    SPClientTemplates.TemplateManager.RegisterTemplateOverrides(overrideCurrentContext);
})();

function changeNoListItemMessage(ctx) {
    ctx.ListSchema.NoListItem = "No data";
}

JSLink URL Tokens in SharePoint

May 17, 2017 / Kannan / 0 Comments

Following are some of the JSLink URL Tokens I have come across in SharePoint.

  • ~site – reference to the current SharePoint site (or “Web”)
  • ~sitecollection – reference to the current SharePoint site collection (or “Site”)
  • ~layouts – version specific reference to the web application Layouts folder (so it will automatically swap out /_layouts/14 or /_layouts/15 for you)
  • ~sitecollectionlayouts – reference to the layouts folder in the current site collection (e.g. /sites/team/_layouts/15)
  • ~sitelayouts – reference to the layouts folder in the current site (e.g. /sites/teams/subsite/_layouts/15)

Few Examples:

~sitecollection/_catalogs/masterpage/
~site/siteassets/
~layouts/reputation.js
