您好，我试图根据视口的高度以及单击特定的切换按钮来更改svg路径的颜色。到目前为止，代码通过在达到50时更改颜色来起作用。我要尝试的是，当屏幕高于470时，它应该为白色（初始状态），但是通过单击切换按钮将颜色更改为黑色。
如果视口在470以下，它应该变为黑色，并且该拨动开关不起作用。因此，切换功能不应为类提供低于470的新背景色。仅应在470以上。
这就是我的jquery，它添加了一个基于视口的类，因此它可以更改颜色：
$(function() {
$(window).scroll(function() {
if ($(this).scrollTop() > 470) {
$('.test').addClass('changeColor')
}
if ($(this).scrollTop() < 470) {
$('.test').removeClass('changeColor')
}
});
});.test {
fill: white;
transition: all ease-in .3s;
}
.changeColor {
fill: black;
}
.changeColortwo {
background-color: black;
}
svg {
position: fixed;
}
body {
height: 2000px;
background-color: #fff;

</svg>到目前为止，此功能可以正常使用，但click事件无效。我只是在脚本中添加了click事件，但是这一事件被忽略了。
$(function() {
$(window).scroll(function() {
if ($(this).scrollTop() > 470) {
$('.test').addClass('changeColor')
$(".clickable").click(function() {
$(this).addClass("changeColortwo");
});
}
if ($(this).scrollTop() < 470) {
$('.test').removeClass('changeColor')
}
});
});
我到底在做什么错？
应该是这样。因为一个事件不能在另一个事件中监听。
$(function() {
$(window).scroll(function() {
if ($(this).scrollTop() > 470) {
$('.test').addClass('changeColor')
}
if ($(this).scrollTop() < 470) {
$('.test').removeClass('changeColor')
}
});
$(".clickable").click(function() {
if ($(this).scrollTop() > 470) {
$(this).addClass("changeColortwo");
}
});
});
