[英]Animated cursor not working with anchors
我搜索了幾個小時但似乎找不到答案。 我正在嘗試調整此codepen https://codepen.io/Nharox/pen/akgEQm來處理圖像和鏈接,但有兩件事情無效。 一個是光標的位置與瀏覽器或鼠標滾輪滾動后鼠標指針的垂直位置不匹配,另一個是單擊鏈接無效。 我似乎無法弄清楚為什么。
<body>
<div class="cursor hidden">
<div class="cross">
<div class="b b1"></div>
<div class="b b2"></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);
}
})();
我需要圖像的大小是瀏覽器寬度的100%。 否則光標正常工作,並且與codepen完全一樣。 只是沒有可點擊的鏈接和錯誤的y位置。
首先,Y位置是正確的,因為您沒有注冊事件監聽器來相應地更新您的Y位置。 到目前為止,你只有鼠標 - 進入,移動和離開事件。 為了解決由於滾動而發生的光標位置變化(btw而不是光標事件),您需要注冊一個scoll事件並相應地更新光標Y位置值。
其次,錨沒有做任何事情,因為它在大海撈針中丟失了。 要使其工作,您可以將“box”元素包裝在錨標記中。
這是更改的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>
這是改變的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;
}
})
})();
