It’s very frustrating to have to work with ASP again, after so many years… I wanted to use an ASP page to get a remote page. However I needed to pass some NTLM authenticate to it. After a few searches I found this solution: <% ‘ I want this page to be accessible for Cross […]

In Sharepoint you can use <WebPartPages:AllowFraming runat=”server” /> to disable the SAMEORIGIN for X-FRAME-OPTION giving you the opportunity to call your page from an iframe (see this other article). However you cannot use the same trick to preview a file into the browser with WopiFrame.aspx. But there is a way to do it, using the […]

Sometimes you want to modify the options for a dropdown box by removing some existing options, however you want to be able to keep these old values for reporting or whatever reasons. Below is a way to do it by using jQuery and SharepointPlus. It will hide the “Specify your own value” stuff, and add […]

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 […]

EDIT: it might also be interesting to look at Intersection Observer that is now available in several browsers, and there is also a polyfill. 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 […]

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)}); // […]
