Shiny.onInputChange is not a function

I have code like is in my shiny app:

$(function() { Shiny.onInputChange('initialHash', parseHashQuery()); }); function parseHashQuery() { var result = {}; location.hash.replace(/^#/, '').split('&').filter(Boolean).forEach(function(part) { var pair = part.split('='); result[pair[0]] = pair[1]; }); return result; }

but I've got error:

common.js:59 Uncaught TypeError: Shiny.onInputChange is not a function at HTMLDocument.<anonymous> (common.js:59) at i (jquery.min.js:2) at Object.fireWith [as resolveWith] (jquery.min.js:2) at Function.ready (jquery.min.js:2) at HTMLDocument.K (jquery.min.js:2)


The solution was to use shiny event:

$(document).on('shiny:sessioninitialized', function(event) { Shiny.onInputChange('initialHash', parseHashQuery()); });

which was executed when Shiny.onInputChange was already defined.

Looking at the source code, Shiny is initialized in jQuery ready function but with timeout:

$(function() { // Init Shiny a little later than document ready, so user code can // run first (i.e. to register bindings) setTimeout(initShiny, 1); });
