$.fire 怎么出去的

$.fire = function(webview, eventType, data) {
console.log("data1"+data);
console.log("$.isPlainObject(data)"+$.isPlainObject(data));
if (webview) {
if (data !== '') {
data = data || {};
if ($.isPlainObject(data)) {
console.log("SON.stringify(data) "+JSON.stringify(data));
data = JSON.stringify(data || {}).replace(/\'/g, "\u0027").replace(/\/g, "\u005c");
}
}
console.log("data2"+data);
webview.evalJS("typeof mui!=='undefined'&&mui.receive('" + eventType + "','" + data + "')");
}
};
/**

• 5+ event(5+没提供之前我自己实现)
• @param {type} eventType
• @param {type} data

• @returns {undefined}
  */
  $.receive = function(eventType, data) {
  if (eventType) {
  try {
  if (data) {
  data = JSON.parse(data);
  }
  } catch (e) {}
  $.trigger(document, eventType, data);
  }
  };
  var triggerPreload = function(webview) {
  if (!webview.preloaded) {
  $.fire(webview, 'preload');
  var list = webview.children();
  for (var i = 0; i < list.length; i++) {
  $.fire(list[i], 'preload');
  }
  webview.preloaded = true;
  }
  };
  var trigger = function(webview, eventType, timeChecked) {
  console.log("timeChecked "+timeChecked);
  if (timeChecked) {
  if (!webview[eventType + 'ed']) {
  $.fire(webview, eventType);
  var list = webview.children();
  console.log("list "+list);
  for (var i = 0; i < list.length; i++) {
  $.fire(list[i], eventType);
  }
  webview[eventType + 'ed'] = true;
  }
  } else {
  $.fire(webview, eventType);
  var list = webview.children();
  console.log("list else "+list);
  for (var i = 0; i < list.length; i++) {
  $.fire(list[i], eventType);
  }
  }

  };

这上面触发mui.fire这么一直在一个自己调用的循环内啊，这么出去的，我没看明白，希望各位指点下。。谢谢。。。。追加一句，我知道什么原因了，晚上我自己眼迷糊了，看错了，，，，，
