我开始修改我网站上的标题,并且很难让它按照我想要的方式工作。
我想要,标题背景将背景颜色更改为白色,向下滚动100-150像素,与此site完全一样。
我找到了这个JS:
$(function(){
$('#header_nav').data('size','big');
});
$(window).scroll(function(){
if($(document).scrollTop() > 0) {
if($('#header_nav').data('size') == 'big') {
$('#header_nav').data('size','small');
$('#header_nav').stop().animate({
height:'40px'
},600);
}
}
else {
if($('#header_nav').data('size') == 'small') {
$('#header_nav').data('size','big');
$('#header_nav').stop().animate({
height:'100px'
},600);
}
}});
我在my WP site中插入自定义JS插件。
还有这个JS:
<script>
$(window).on("scroll", function() {
if ($(this).scrollTop() > 100) {
$("header").css("background","#252525");
}
else {
$("header").css("background","#fff");
}
});
</script>
这可能是更好的解决方案,然后是之前的代码吗?
如何使用此JS在我发布的演示网站上发布效果?

您引用的网站使用bootstrap框架。 您可以通过右键单击该站点并查看inspect元素来查看该站点上的操作。以下代码是针对导航栏找到的:这样您就不需要编写自定义js,jut遵循行业最佳实践。
<nav class="navbar navbar-dark navbar-fixed-top top-nav-collapse" role="navigation">
<div class="navbar-container">
<div class="navbar-header page-scroll">
<button type="button" class="navbar-toggle" data-toggle="collapse" data-target=".navbar-main-collapse">

使用以下代码段,在演示网站中正常运行
jQuery(document).scroll(function(){
if(jQuery(this).scrollTop() > 300)
{
jQuery('#navigation').css({"background":"red"});
} else {
jQuery('#navigation').css({"background":"transparent"});
}
});

试试这段代码。
$(function() {
var bgcolor_navigation = function(){
var bg_offset_top = $(window).scrollTop(); // our current vertical position from the top
if ((100 > bg_offset_top) &&(150 < bg_offset_top)) {
$('#navigation').addClass("bgcolorheadnav");
} else {
$('#navigation').removeClass("bgcolorheadnav");
}
};
// run our function on load
bgcolor_navigation();
// and run it again every time you scroll
$(window).scroll(function() {
bgcolor_navigation();
});
});
<强> CSS 强>
.bgcolorheadnav{
background-color:#000;
}

这仅适用于WordPress制作的网站:

如果您不以这种方式执行CSS并将代码放入主题 - &gt; style.css,您将放弃在将来更新主题时所做的所有更改。
