How to configure XML for LTI to open in new tab?

Hi Everyone,

I was installing a LTI application to canvas. I want this LTI to appear in User navigation and Course Navigation of canvas. And when someone clicks on it, it should open in new tab. After installing this everything is fine except one. LTI app is not appearing in the new tab. I found in configuration API Importing Extended Tool Configurations - Canvas LMS REST API Documentation following code for new tab windowTarget ">_blank

Below is XML for my LTI:

<?xml version="1.0" encoding="UTF-8"?>

http://www.imsglobal.org/xsd/imslticc_v1p0"

xmlns:blti = "http://www.imsglobal.org/xsd/imsbasiclti_v1p0"

xmlns:lticm ="http://www.imsglobal.org/xsd/imslticm_v1p0"

xmlns:lticp ="http://www.imsglobal.org/xsd/imslticp_v1p0"

xmlns:xsi = "http://www.w3.org/2001/XMLSchema-instance"

xsi:schemaLocation = "http://www.imsglobal.org/xsd/imslticc_v1p0 http://www.imsglobal.org/xsd/lti/ltiv1p0/imslticc_v1p0.xsd

@zweifel your XML looks like it's missing some stuff, but if it's working...

Have you looked at this tool to help generate your XML:

XML Config Builder

Anyway, try moving your "windowTarget" into your placement options.

Using your XML it would look like this:

true

_blank

true

_blank

Placing the "windowTarget" in my XML like this is working, launching my LTI tool in a new browser tab.

I hope this helps.

Hi. Does anyone know if there is there a property that will set the order of the menu item in course nav?

The windowTarget _blank property does not work with user_navigation link placement. Even if you set it in the XML, the link will still open in Canvas in-frame. I thought I should mention this because the conversation at the top of this thread implies that it is possible to open in a new tab. This may have worked in the past; if so, something changed in Canvas so it no longer functions with this particular placement.

Hey all, sometimes you need to create LTIs (external tools) on a mass scale OR make changes on a mass scale. I put together this Python script to do just that. Maybe this will help someone.

Provided 'as is', but it works pretty well.

Here's some code you can use in the javascript console to update any arbitrary object value.

// take the object that you got from the url and update it with the partial object you have
function updateObjVal(object, searchObj) {
	//console.log(object);
    Object.keys(searchObj).forEach(function (k) {
        if (object[k] && typeof object[k] === 'object' && typeof searchObj[k] === 'object') {
            return updateObjVal(object[k], searchObj[k])
        }
		else{
			object[k] = searchObj[k];
		}
    });
	return object;
}

// get the existing json from the url
function updateTool(url, updateObj){
	$.ajax({
	url: url,
	type: 'GET',
	success: function(data) {
			// console.log(data);
			//console.log(updateObj);
			var updatedObj = updateObjVal(data,updateObj);
			putUpdate(url,updatedObj);
		}
	});
}

// send the updated json back
function putUpdate(url, updatedObj){
	console.log(updatedObj);
	var updateString = decodeURIComponent(jQuery.param( updatedObj ));
	$.ajax({
		url: url,
		type: 'PUT',
		data: updateString,
		success: function(data) {
			console.log('Tool was updated.');
			}
		});
}

// e.g. /api/v1/courses/281820/external_tools/22087 visible from network panel in console after you look at Placements for example
var targeturl="/api/v1/accounts/3371/external_tools/40870";

// the update object is any fragment of the json that you want to update
var updateObj = {"course_navigation": {
					"default": "disabled",
					 "text": "Some Name",
					 "label": "Some Name"
					}
				};

updateTool( targeturl, updateObj );

Sure. I tend to forget that I have the JSON Formatter Chrome Extension that makes JSON really easy to look at and decipher, but you just need to look at the JSON and only need to include the object attribute you want to change or add, i.e.

var updateObj = {"account_navigation": {
"windowTarget": "_blank"
}};

sure. My email is my username @vccs.edu
