Shiny.onInputChange不是一个函数

Question

我有像我的闪亮应用程序中的代码:

$(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;
}

但我有错误:

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)

解决方案是使用闪亮的事件:

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

Shiny.onInputChange已经定义时执行的.

查看源代码,Shiny在jQuery ready函数中初始化,但是超时:

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