If you want to trigger an event after a drag&drop a file for an upload operation on Sharepoint, then you’ll have to add some JavaScript into your page. // we need to make sure sp.core.js is loaded SP.SOD.executeOrDelayUntilScriptLoaded(function() { window.UploadFinishFunc=function(b, a) { typeof g_currentControl.postUploadFunc == “function” && a.status != UploadStatus.CANCELLED && g_currentControl.postUploadFunc(a.files); a.status != UploadStatus.CANCELLED […]

This article has been VERY useful. But I wanted something lightly different: I wanted to add a custom action, but also have the “EDIT” button (but not the “SHARE”), and to use the current item info for my custom action. Here is the result: // source: https://www.eliostruyf.com/adding-a-custom-action-to-a-callout-in-sharepoint-2013/ // add a special callout action for our […]

I have this specific need that is to trigger an event when an element becomes visible/invisible into a scrollable area. Here is the code I came to: /** * Create the handler * @param {NodeElement} holder The scrollable area to monitor (where the ‘scroll’ event will be apply) */ var VisibleEventListener = function(holder) { var […]

Below is a code example that is handy when you want to execute several Promise actions in sequence: function go(files) { var dfd = Promise.resolve(); var res = files.map(function(file) { dfd = dfd.then(function() { return performComputation(file); }); return dfd }); return Promise.all(res) } function performComputation(file) { console.log(“Dealing with “+file); return new Promise(function(res, rej) { setTimeout(function() […]

We can find many discussions and solutions about this issue. In my case the one that worked is this code. Below you’ll find a compressed version of the extend() function (with a fix): function extend(){var r,t,n,o,e=arguments[0]||{},f=1,i=arguments.length,u=!1,y=function(r){if(null===r||”object”!=typeof r||r.nodeType||null!==r&&r===r.window)return!1;try{if(r.constructor&&!this.hasOwnProperty.call(r.constructor.prototype,”isPrototypeOf”))return!1}catch(t){return!1}return!0};for(“boolean”==typeof e&&(u=e,e=arguments[f]||{},f++),”object”!=typeof e&&”function”!=typeof e&&(e={}),!1;i>f;f+=1)if(null!==(r=arguments[f]))for(t in r)e!==r[t]&&”undefined”==typeof e[t]&&(u&&r[t]&&(y(r[t])||(n=Array.isArray(r[t])))?(n?(n=!1,o=e[t]&&Array.isArray(e[t])?e[t]:[]):o=e[t]&&y(e[t])?e[t]:{},e[t]=extend(u,o,r[t])):void 0!==r[t]&&(e[t]=r[t]));return e} And here an example: var object_a = { value_1: ‘a’, […]

In some cases you could get this kind of hexadecimal numbers from Sharepoint for the PermMask: 0xb008431061, or 0x1b03c4313ff, and so on. To verify the PermMask against the different level of permissions you can proceed with the below method (using functions from core.js): var permMask = ‘0x1b03c4313ff’; var permissions = new SP.BasePermissions(); permissions.initPropertiesFromJson({High:GetPermMaskH(permMask), Low:GetPermMaskL(permMask)}); // […]

Sharepoint encodes the URLs with unicode, so we’ll see many \u002f to represent /. If you want to decode those unicode strings, you can use this short code: unescape(JSON.parse(‘”‘ + s.replace(‘”‘, ‘\\”‘) + ‘”‘)

When I open a dialog for an EditFrom and use the “Delete Item” button from the ribbon, then the main page is redirected to the related Sharepoint list. This behavior is very bad for the user experience. To change it I used the below Javascript code: // replace the Delete Item default action when into […]

With Sharepoint 2010, when you use Internet Explorer you can open an Office document in readonly or in edit mode. Also, when trying to open an Excel file in Firefox/Chrome it will probably open the ugly xslviewer and won’t let you deal with your file. After searching a bit about it, I found a clue […]
