当您向下滚动一定数量时,我的内容会从页面底部向上滑动。
点击按钮将关闭上滑。
但如果继续向下滚动页面,则会再次出现上滑。
如果只点击一次关闭按钮,如何让幻灯片一劳永逸地消失?
这是脚本:
$(document).ready(function(){
$(window).scroll(function(){
var h = $('#container').height();
var y = $(window).scrollTop();
if( y > (h*.25) ) {
$("#btmsUpContainer").slideDown("slow");
} else {
$("#btmsUpContainer").slideUp("slow");
}
});
$('.close-it').bind('click', function() {
$("#btmsUpContainer").slideUp("slow");
return false;
});
})
这是CSS:
#btmsUpContainer { position: fixed; width: 170px; bottom: 29px; z-index: 7777; margin: 0; padding: 0; display: none; }
#btmsUp { left: 0; width: 170px; margin: 0; }
#btmsUp .close-it { position: absolute; left: 160px; top: 12px; right: 0; z-index: 7778; width: 10px; }
这是页码:
<div id="btmsUpContainer">
<div id="btmsUp">
<span class="close-it"><a href="#"><img src="close-it.png" style="width: 10px; height: 10px; border: 0;"></a></span><br />
This is stuff that appears in the box that slides up.
</div>
</div>

当用户关闭内容时设置hidden
变量,并在滑动前检查它:
$(document).ready(function(){
var hidden = false; //Initialize the 'hidden' variable to 'false'
$(window).scroll(function(){
if(!hidden){ //Check if the user has hidden the content
var h = $('#container').height();
var y = $(window).scrollTop();
if( y > (h*.25) ) {
$("#btmsUpContainer").slideDown("slow");
} else {
$("#btmsUpContainer").slideUp("slow");
}
}
});
$('.close-it').bind('click', function() {
$("#btmsUpContainer").slideUp("slow");
hidden = true; //Set the 'hidden' variable to 'true'
return false;
});
})
