jquery.ui.touch-punch.jsをSurfaceのタッチパネルでも使えるようにする

概要

jQuery UIをタッチイベントに対応させるライブラリに
jquery.ui.touch-punch.jsがあるが、
surfaceのタッチイベントでは動かないので
jquery.ui.touch-punch.jsを修正する。

施策

  $.support.touch = 'ontouchend' in document;

上記スクリプトの下に追加

  $.support.touch = 'ontouchend' in document;

  //追加
  if('onpointerenter' in window){
    $.support.touch = true;
  }

解説

「Ignore browsers without touch support」の行で
タッチデバイス以外は処理を中断するスクリプトが記述されているため、
ポインタデバイスであるsurfaceでは動かなくなる。

  // Detect touch support
  $.support.touch = 'ontouchend' in document;

  if('onpointerenter' in window){
    $.support.touch = true;
  }

    // Ignore browsers without touch support
  if (!$.support.touch) {
    return;
  }
