- html - 出于某种原因,IE8 对我的 Sass 文件中继承的 html5 CSS 不友好?
- JMeter 在响应断言中使用 span 标签的问题
- html - 在 :hover and :active? 上具有不同效果的 CSS 动画
- html - 相对于居中的 html 内容固定的 CSS 重复背景?
在代码中,处理程序被多次调用。
它应该只被调用一次。
代码中是如何修复的,需要调整什么?
在 jsfiddle 内的 console 中,它说,1, 3, 6, 10, 15
单击退出按钮一次得到 1
第二次给出,3
第三次:6
第4次:10
第5次:15
这些数字应该是。
1, 2, 3, 4, 5
点击退出按钮后。 https://jsfiddle.net/yb0tn7p9/
function createResetHandler(player) {
const resetVideos = document.querySelectorAll('.exit');
resetVideos.forEach(function resetVideoHandler(video) {
video.addEventListener('click', function resetVideoHandler() {
player.destroy();
console.log('hit')
}
);
}
)
}
要重现:首先单击播放 svgs,然后多次单击 X。
点击 X
然后数字出现在 jsfiddle 的控制台中。

最佳答案
每次调用 createResetHandler 函数时,它都会为所有按钮分配一个新的事件监听器。
同样在 createResetHandler 函数中,播放器参数应该用于创建相关按钮的事件监听器,而不是所有按钮。
只需删除createResetHandler 函数并将以下代码放入makeVideoPlayer 函数
document.querySelectorAll(".exit").forEach((button) => {
button.onclick = (e) => {
const _iframe = e.currentTarget.parentElement.querySelector("iframe");
// check if the video exists
if (_iframe) {
// find its player and destroy it
for (let i = 0, playersCount = players.length; i < playersCount; i++) {
const player = players[i];
if (player.h === _iframe) {
player.destroy();
console.log("hit");
break;
}
}
}
};
});
