vue 拖拽指令问题

vue 拖拽指令问题

问题:添加在父元素和子元素上,拖拽子元素会触发父元素拖动,子元素未被单独拖动
封装指令代码如下:

Vue.directive("drag", {

bind: function(el) {

let odiv = el; //获取当前元素

console.log("####1",odiv)

odiv.onmousedown = e => {

console.log("####2")

//算出鼠标相对元素的位置

let disX = e.clientX - odiv.offsetLeft;

let disY = e.clientY - odiv.offsetTop;

document.onmousemove = e => {

console.log("####3")

//用鼠标的位置减去鼠标相对元素的位置,得到元素的位置

let left = e.clientX - disX;

let top = e.clientY - disY;

//绑定元素位置到positionX和positionY上面

e.positionX = top;

e.positionY = left;

//移动当前元素

odiv.style.left = left + "px";

odiv.style.top = top + "px";

odiv.style.right = "auto";

odiv.style.bottom = "auto";

e.stopPropagation();

};

document.onmouseup = () => {

document.onmousemove = null;

document.onmouseup = null;

};

};

odiv.ontouchstart = e => {

let disX = e.touches[0].clientX - odiv.offsetLeft;

let disY = e.touches[0].clientY - odiv.offsetTop;

document.ontouchmove = e => {

//用鼠标的位置减去鼠标相对元素的位置,得到元素的位置

let left = e.touches[0].clientX - disX;

let top = e.touches[0].clientY - disY;

//绑定元素位置到positionX和positionY上面

e.touches[0].positionX = top;

e.touches[0].positionY = left;

//移动当前元素

odiv.style.left = left + "px";

odiv.style.top = top + "px";

odiv.style.right = "auto";

odiv.style.bottom = "auto";

e.stopPropagation();

};

document.ontouchend = () => {

document.ontouchend = null;

document.ontouchmove = null;

};

};

}

});

DOM结构:

  <div class="video"  v-drag>

<div class="video_control" v-drag></div>

</div>

CSS代码:

<style lang="scss" scoped>

.video {

position: absolute;

top: 100px;

left: 100px;

right: auto;

bottom: auto;

z-index: 1000;

.video_control{

width: 48%;

height: 48%;

position: absolute;

top: auto;

left: auto;

right: 0;

bottom: 0;

}

}

</style>


回答:

event.stopPropagation(),阻止事件冒泡
