accessing window.jQuery / window.$

blumi78 — Wed, 17 Jan 2018 11:24:09 GMT

Why does PowerBI inserts this code segment to all Custom Visuals?

//de-reference powerbi loaded modules
var $, jQuery, _;
window.jQuery = window.$ = undefined;
window._ = undefined;

And why are these variables still functional using the F12 tools in the browser?

> $("body")[0]
<body class="visual-sandbox">…</body>

Wouldn't it be much more convenient to be able to use these already loaded libraries in the custom visuals instead of reload them a second time?

Power BI inserts this code to protect integrated jQuery from being replacented by custom visual's version.

This code isolates PBI libraries from custom visual ones.
