我有一个通过 ajax 动态加载内容的导航。但是,如果我刷新页面或访问另一个 url 并返回当前内容,我会在第一个菜单选项卡下看到旧内容。
解决此问题的最佳方法是什么?你能给我一些代码吗?
index.php 包括元素 navigation.inc.php 和 main_container.inc.php
<?php include("inc/incfiles/header_registrated.inc.php"); ?>
<?php
if (!isset($_SESSION["userLogin"])) {
echo "<meta http-equiv=\"refresh\" content=\"0; url=http://localhost/project\">";
}
else {
echo "";
}
?>
<?php include("inc/incfiles/navigation.inc.php"); ?>
<?php include("inc/incfiles/main_container.inc.php"); ?>
<?php include("inc/incfiles/footer.inc.php"); ?>
导航.inc.php:
<div class="navigation">
<ul>
<li id="1">
<div id="menuImage1" class="menuImage"></div>
<div class="menuText"><p>Punkt 1</p></div>
<div class="navigationDart"></div>
</li>
<li id="2">
<div id="menuImage2" class="menuImage"></div>
<div class="menuText"><p>Punkt 2</p></div>
</li>
<li id="3">
<div id="menuImage3" class="menuImage"></div>
<div class="menuText"><p>Punkt 3</p></div>
</li>
<li id="4">
<div id="menuImage4" class="menuImage"></div>
<div class="menuText"><p>Punkt 4</p></div>
</li>
<li id="5">
<div id="menuImage5" class="menuImage"></div>
<div class="menuText"><p>Punkt 5</p></div>
</li>
<li id="6">
<div id="menuImage6" class="menuImage"></div>
<div class="menuText"><p>Punkt 6</p></div>
</li>
</ul>
</div>
main_container.inc.php:
<div class="mainContainer">
<div class="containerHeader">
<div class="contentHeader">
</div>
</div>
<div class="contentContainer">
<div class="content">
</div>
<div class="advertisement">
</div>
</div>
</div>
现在 div 内容、cnotentHeader 和广告(在文件 main_content.inc.php 中)通过 ajax 填充。此外,导航有一些 jquery 效果,在页面刷新后也必须相同。
$(document).ready(function() {
$.get('inc/incfiles/content_container/header/1.php', function(data) {
$('.contentHeader').html(data);
});
$.get('inc/incfiles/content_container/content/1.php', function(data) {
$('.content').html(data);
});
$.get('inc/incfiles/content_container/advertisement/1.php', function(data) {
$('.advertisement').html(data);
});
var current = '1.php';
$(".navigation li").click(function() {
var quelle = $(this).attr('id') + ".php";
// the current content doesn't load again
if(current === quelle) {
return;
}
current = quelle;
// content
$(".content").fadeOut(function() {
$(this).load("inc/incfiles/content_container/content/" + quelle).fadeIn('normal');
})
// advertisement
$(".advertisement").fadeOut(function() {
$(this).load("inc/incfiles/content_container/advertisement/" + quelle).fadeIn('normal');
})
// header
$(".contentHeader").fadeOut(function() {
$(this).load("inc/incfiles/content_container/header/" + quelle).fadeIn('normal');
})
});
$(".navigation li").click(function() {
$(".menuImage").removeClass("menuImageActive1");
$(".menuImage").removeClass("menuImageActive2");
$(".menuImage").removeClass("menuImageActive3");
$(".menuImage").removeClass("menuImageActive4");
$(".menuImage").removeClass("menuImageActive5");
$(".menuImage").removeClass("menuImageActive6");
});
$("#1").mousedown(function() {
$("#menuImage1").addClass("menuImageClick1"); // new class on mouse button press

$("#menuImage5").addClass("menuImageActive5");
});
$("#6").mousedown(function() {
$("#menuImage6").addClass("menuImageClick6"); // new class on mouse button press
});
$("#6").mouseup(function() {
$("#menuImage6").removeClass("menuImageClick6"); //remove class after mouse button release
});
$("#6").click(function() {
$("#menuImage6").addClass("menuImageActive6");
});
$("#1").click(function(){
$(".navigationDart").animate({
top: "16px"
}, 500 );
});
$("#2").click(function(){
$(".navigationDart").animate({
top: "88px"
}, 500 );
// Get the src of the image
// var src = $(this).css("top");
// Send Ajax request to backend.php, with src set as "img" in the POST data
// $.post("/home.php", {"#2": top});
});
$("#3").click(function(){
$(".navigationDart").animate({
top: "160px"
}, 500 );
});
$("#4").click(function(){
$(".navigationDart").animate({
top: "232px"

});

});
$("#6").click(function(){

}, 500 );
});
});
