我已经为此苦苦挣扎了两天。此 JavaScript 应在加载时加载我的 home.html 页面，然后在单击链接时加载我的其他页面。连首页都加载不出来。为什么什么都没有加载对我来说没有任何意义。谁能看到我的错误在哪里？
JAVASCRIPT：
$(document).ready(function(){
setOrientationListener();
changePage('home.html?v=1');
$('nav a').on('click', function(){
$('nav a').removeClass('selected');
$(this).addClass('selected');
})
});
function changePage(fileName){
$('.content_container').animate({opacity:0}, 500, function(){
$('.content_loading_container').load('assets/content/'+fileName, function(){
$('.content_container').delay(250).animate({opacity:1}, 500);
});
});
}
