动画光标不适用于锚点

[英]Animated cursor not working with anchors

我搜索了几个小时但似乎找不到答案。 我正在尝试调整此codepen https://codepen.io/Nharox/pen/akgEQm来处理图像和链接,但有两件事情无效。 一个是光标的位置与浏览器或鼠标滚轮滚动后鼠标指针的垂直位置不匹配,另一个是单击链接无效。 我似乎无法弄清楚为什么。

<body>
<div class="cursor hidden">
    <div class="cross">
        <div class="b b1"></div>
        <div class="b b2"></div>
    </div>
    <svg class="circle" xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" preserveAspectRatio="xMidYMid" width="52" height="52" viewBox="0 0 52 52">
        <path d="M1,26a25,25 0 1,0 50,0a25,25 0 1,0 -50,0"/>
    </svg>
</div>

链接

<div class="myrow">
    <div class="myrow__box">
        <a href="/link-to-page"><img alt="" src="/images/myimage.jpg" /></a>
    </div>
</div>

JS

(function showCursor() {
'use strict';
// Variables
var boxes = document.querySelectorAll('.myrow__box'),
    cursor = document.querySelector('.cursor'),
    boxPos = [];
// Get coordinates for the current cursor position
function getPos(e, el) {
    var xPos = 0,
        yPos = 0;
    xPos = (el.offsetLeft - el.scrollLeft + el.clientLeft);
    yPos = (el.offsetTop - el.scrollTop + el.clientTop);
    var mouseX = e.clientX - xPos,
        mouseY = e.clientY - yPos; 
    cursor.style.top = '' + mouseY + 'px';
    cursor.style.left = '' + mouseX + 'px';
}
// Add event listeners and call fns for the corresponding box
for (var i = 0; i < boxes.length; i++) {
    boxes[i].addEventListener('mousemove', function(event) {
        var currentBox = this;
        boxPos = getPos(event, currentBox);
    }, false);
    boxes[i].addEventListener('mouseenter', function() {
        this.appendChild(cursor);
         setTimeout(function() {
             cursor.classList.add('cursor-is-visible')
         }, 10);
    }, false);
    boxes[i].addEventListener('mouseleave', function() {
        cursor.classList.remove('cursor-is-visible');
    }, false);
}
})();

我需要图像的大小是浏览器宽度的100%。 否则光标正常工作,并且与codepen完全一样。 只是没有可点击的链接和错误的y位置。

首先,Y位置是正确的,因为您没有注册事件监听器来相应地更新您的Y位置。 到目前为止,你只有鼠标 - 进入,移动和离开事件。 为了解决由于滚动而发生的光标位置变化(btw而不是光标事件),您需要注册一个scoll事件并相应地更新光标Y位置值。

其次,锚没有做任何事情,因为它在大海捞针中丢失了。 要使其工作,您可以将“box”元素包装在锚标记中。

这是更改的HTML:

<a href="www.google.com" target="_blank">
    <div class="myrow">
        <div class="myrow__box">
            <img alt="" src="https://www.easyjet.com/en/holidays/shared/images/guides/austria/vienna.jpg" />
        </div>
    </div>
</a>

这是改变的JS:

(function showCursor() {
'use strict';
// Variables
var boxes = document.querySelectorAll('.myrow__box'),
    cursor = document.querySelector('.cursor'),
    boxPos = [],
    scrollY = 0;
// Get coordinates for the current cursor position
function getPos(e, el) {
    var xPos = 0,
        yPos = 0;
        xPos = (el.offsetLeft - el.scrollLeft + el.clientLeft);
        yPos = (el.offsetTop - el.scrollTop + el.clientTop);
    var mouseX = e.clientX - xPos,
        mouseY = e.clientY - yPos + scrollY; 
    cursor.style.top = '' + mouseY + 'px';
    cursor.style.left = '' + mouseX + 'px';
}
// Add event listeners and call fns for the corresponding box
for (var i = 0; i < boxes.length; i++) {
boxes[i].addEventListener('mousemove', function(event) {
    var currentBox = this;
    boxPos = getPos(event, currentBox);
}, false);
boxes[i].addEventListener('mouseenter', function() {
    this.appendChild(cursor);
     setTimeout(function() {
         cursor.classList.add('cursor-is-visible')
     }, 10);
}, false);
boxes[i].addEventListener('mouseleave', function() {
    cursor.classList.remove('cursor-is-visible');
}, false);
}
window.addEventListener('scroll', function (event) {
    if(event.target.scrollingElement.localName == "body") {
        scrollY = event.target.scrollingElement.scrollTop;          
    }
})     
})();
