elementUI vue this.$confirm 和el-dialog 弹出框 拖动
el-dialog 弹出框 拖动
// v-dialogDrag: 弹窗拖拽
Vue.directive
('dialogDrag',
{
bind
(el, binding, vnode, oldVnode
) {
const dialogHeaderEl
= el.querySelector
('.el-dialog__header')
const dragDom
= el.querySelector
('.el-dialog')
dialogHeaderEl.style.cursor
= 'move'
// 获取原有属性 ie dom元素.currentStyle 火狐谷歌 window.getComputedStyle
(dom元素, null
);
const sty
= dragDom.currentStyle
|| window.getComputedStyle
(dragDom, null
)
dialogHeaderEl.onmousedown
= (e
) => {
// 鼠标按下,计算当前元素距离可视区的距离
const disX
= e.clientX - dialogHeaderEl.offsetLeft
const disY
= e.clientY - dialogHeaderEl.offsetTop
// 获取到的值带px 正则匹配替换
let styL, styT
// 注意在ie中 第一次获取到的值为组件自带50% 移动之后赋值为px
if (sty.left.includes
('%')) {
styL
= +document.body.clientWidth *
(+sty.left.replace
(/\%/g,
'') / 100
)
styT
= +document.body.clientHeight *
(+sty.top.replace
(/\%/g,
'') / 100
)
} else {
styL
= +sty.left.replace
(/\px/g,
'')
styT
= +sty.top.replace
(/\px/g,
'')
}
document.onmousemove
= function
(e
) {
// 通过事件委托,计算移动的距离
const l
= e.clientX - disX
const t
= e.clientY - disY
// 移动当前元素
dragDom.style.left
= `${l + styL}px`
dragDom.style.top
= `${t + styT}px`
// 将此时的位置传出去
// binding.value
({x:e.pageX,y:e.pageY
})
}
document.onmouseup
= function
(e
) {
document.onmousemove
= null
document.onmouseup
= null
}
}
}
})
在
<el-dialog v-dialogDrag
></el-dialog
> 这么用
elementUI vue this.$confirm 弹出框 移动
//elementUI vue this.
$confirm 弹出框移动
$(function () {

总结: 首先得引用在main.js引用应用jquery.js和dialogdrage.js。 我把两段代码都放到命名为dialogdrage里面,jquery和js最好放到utils文件夹下进行引用。
