我正在创建一个BackboneJS项目。它在Chrome和Safari中运行良好,但在Firefox中,我收到错误,导致我的应用无法加载,我无法解决原因。
错误出现在我的jQuery文件中,但显然我的应用程序中有一个触发它,因为jQuery库本身就很好。
在jQuery“createSafeFragment”方法的第二行抛出错误:
function createSafeFragment( document ) {
var list = nodeNames.split( "|" ),
safeFrag = document.createDocumentFragment();
if ( safeFrag.createElement ) {
while ( list.length ) {
safeFrag.createElement(
list.pop()
);
}
}
return safeFrag;
}
运行应用程序的我的main.js:
Backbone.View.prototype.close = function () {
if (this.beforeClose) {
this.beforeClose();
}
this.remove();
this.unbind();
};
var AppRouter = Backbone.Router.extend({
routes: {
'': 'home',
'login' : 'login',
'register' : 'register',
'rosters' : 'rosters',
'workplaces' : 'workplaces',
'groups' : 'groups',
'shifts' : 'shifts',
'logout' : 'logout'
},
content : '#content',
initialize: function () {
window.headerView = new HeaderView();
$('.header').html(window.headerView.render().el);
},
home: function () {
window.homePage = window.homePage ? window.homePage : new HomePageView();
app.showView( content, window.homePage);
window.headerView.select('home');
},
register: function () {
window.registerPage = window.registerPage ? window.registerPage : new RegisterPageView();
app.showView( content, window.registerPage);
window.headerView.select('register');
},
login: function() {
app.showView( content, new LoginPageView());
window.headerView.select('login');
},
rosters: function () {
if(Utils.checkLoggedIn()){
app.showView( content, new RosterPageView());
window.headerView.select('rosters');
}
},
groups: function () {
if(Utils.checkLoggedIn()){
app.showView( content, new GroupsPageView());
window.headerView.select('groups');
}
},
shifts: function () {
if(Utils.checkLoggedIn()){
app.showView( content, new ShiftsPageView());
window.headerView.select('shifts');
}
},
workplaces: function () {
if(Utils.checkLoggedIn()){
app.showView( content, new WorkplacesPageView());
window.headerView.select('workplaces');
}
},
logout: function () {
window.headerView.toggleLogin(false);
this.login();
},
showView: function(selector, view) {
if (this.currentView)
this.currentView.close();
$(selector).html(view.render().el);
this.currentView = view;
return view;
}
});
Utils.loadTemplates(['HomePageView', 'HeaderView', 'LoginPageView', 'RegisterPageView',
'RostersPageView', 'GroupsPageView', 'ShiftsPageView', 'UserListView',
'GroupListView', 'ShiftListView', 'SearchedUserListView', 'SearchedGroupListView',
'GroupRosterView', 'RosterListView', 'WorkplacesPageView', 'WorkplaceListView',
'SearchedWorkplaceListView', 'RosterJoinListView', 'GroupUserListView',
'WorkplaceRosterView', 'WorkplaceUserListView', 'RosterShiftView'], function(){
app = new AppRouter();
Backbone.history.start();
});
我的Util.js:
Utils = {
//template stuff
templates: {},
loadTemplates: function(names, callback) {
var that = this;
var loadTemplate = function(index) {
var name = names[index];
$.get('tpl/' + name + '.html', function(data) {
that.templates[name] = data;
index++;
if (index < names.length) {
loadTemplate(index);
} else {
callback();
}
});
};
loadTemplate(0);
},
get: function(name) {
return this.templates[name];
},
//error stuff
showAlertMessage: function(message, type){
$('#error').html(message);
$('.alert').addClass(type);
$('.alert').show();
},
showErrors: function(errors) {
_.each(errors, function (error) {
var controlGroup = $('.' + error.name);
controlGroup.addClass('error');
controlGroup.find('.help-inline').text(error.message);
}, this);
},
hideErrors: function () {
$('.control-group').removeClass('error');
$('.help-inline').text('');
},
//validator stuff
validateModel: function(model, attrs){
Utils.hideErrors();
var valError = model.validate(attrs);
if(valError){
Utils.showErrors(valError);
return false;
}
return true;
},
//loading stuff
toggleLoading: function(toggle){
$('#loading').css('visibility', toggle ? 'visible' : 'hidden');
},
//login stuff
login: function(auth){
window.headerView.toggleLogin(true);
Backbone.history.navigate("", true);
},
checkLoggedIn: function(){
if(!window.userId){
window.headerView.toggleLogin(false);
Backbone.history.navigate("login", true);
return false;
}
return true;
},
//util methods
formatDate: function(date){
var formattedDate = '';
formattedDate += date.getFullYear() + '-';
formattedDate += date.getMonth()+1 + '-';
formattedDate += date.getDate();
return formattedDate;
},
formatDateForDisplay: function(date){
var formattedDate = '';
formattedDate += date.getDate() + '/';
formattedDate += date.getMonth()+1 + '/';
formattedDate += date.getFullYear() + ' - ';
formattedDate += ['Sunday','Monday','Tuesday','Wednesday','Thursday','Friday','Saturday'][date.getDay()];
return formattedDate;
},
formatDateForGroup: function(date){
var formattedDate = '';
formattedDate += date.getDate() + '/';
formattedDate += date.getMonth()+1;
return formattedDate;
},
showPopup: function(id, buttons, title, content){
var popup = $(id);
popup.dialog({
modal: true,
title: title,
buttons: buttons
});
popup.find('#popupContent').html(content);
}
};
有人请帮帮我,因为这让我抓狂!仅限Firefox ......
答案 0 :(得分:2)
我也遇到了这个问题。您可以通过执行以下操作重现此错误:
$(window).append('bla');
我的结合起因是:
<a href="#" onClick="doIt(); return false;">click</a>
和
function doIt(){
var newElm = $('<span>hi</span>');
$(this).append(newElm);
//now this === window, and not what I was expecting the a-element
}
这一切都发生了,因为我预计点击会以正确的更多jquery-ish方式绑定到a元素。但有人决定使用1999年代码; p。我希望这个方法能够像这样绑定:
$("a").click(doIt);
在这种情况下这个会绑定到a元素而不是窗口。

benhowdle89发现当我应该追加content
时,我正在追加this.content
。
总是使用我已经意识到的JSFiddle也是一个好主意,所以其他人可以自己看到你的问题。
感谢benhowdle89!
