I'm trying to add jquery to my Seattle masterpage. I followed these directions which say to add the following (modified for my locations) line to the Seattle.html file.

<!--SPM:<SharePoint:ScriptLink language="javascript" name="'~sitecollection/_catalogs/masterpage/custom/js/jquery-1.8.3.min.js" runat="server" Localizable="false" />-->

I added that line right after the other ScriptLinks that were already there. I then load the page back up and I get the "Something went wrong error" when I try and load any page (all the admin ones) that uses it.

Is that the wrong location to add that line?

How can I add jquery to my Seattle masterpage?


Easier than modifiyng the MasterPage:

Use the Chrome Extension SharePoint Editor once


to load jQuery with a UserCustomAction ScriptLink

That will load jQuery early on on every page in the SiteCollection

  • That looks like it is for SP online? I should have specified that we have 2013 on prem. – Rothrock Apr 26 '17 at 15:35
  • UserCustomActions have been around since SP2010, never tried it but that extension should work on all environments, if not check John Lui's blog on UserCustomActions – Danny '365CSI' Engelman Apr 26 '17 at 16:31
  • I couldn't get the extension to do anything, but John Liu's blog worked! – Rothrock Apr 26 '17 at 20:46

An alternate method is to add the <script> tag directly in <head> section in master page as the following:

  • Upload your js file to Asset Library or Style Library in SharePoint site collection.

  • Open SharePoint Designer > Go to Master Page > Right click on your custom master page HTML file and Check it out.

  • Right click -> Edit in advanced mode.
  • In < head > section add your reference of your js file like <script type="text/javascript" src="../../Style Library/JS/jquery7.min.js">

Note: To get the correct URL > write Src=" > then the Pick URL button should be shown, navigate to your js file in Style Library.

  • Save -> Right click Check-in -> Publish As Major version ->

  • This is will open your master page gallery -> right click and select publish.

Alternatively, you can use delegate control as mentioned at Adding jQuery to Every Page in SharePoint with Delegate Controls
