需求:
1.不限制背景图的大小做overflower,标记点位获取相对位置xy,可拖动修改标点位置,可删除标点
2.关联设备后做自定义标记图标
图例:
代码:
1.html
<el-dialog title="设置设备" :visible.sync="imgMark" append-to-body id="plan">
<div class="plan-img">
<img class="bg" :src="bgSrc" @click.stop="setPoint" />
<div v-for="(item, index) in markerArr"
:key="index"
class="block"
:style="{ left: item.x, top: item.y, transform: 'translate(-50%, -100%)' }"
@drag="dragenter($event, item)"
draggable="true">
<img :src="markSrc" class="mark-icon" @click.stop="editPoit(index,item)" />
<div class="button-group" v-if="item.showModal">
<span @click="associative(index)">关联设备</span>
<span @click="deletePoit(index)">删除点位</span>
</div>
</div>
</div>
<div slot="footer" class="dialog-footer">
<el-button type="primary" @click="submitMark" class="button-minwidth">确定</el-button>
<el-button @click="imgMark = false" class="button-minwidth">取消</el-button>
</div>
</el-dialog>

export default {

let y = e.offsetY || e.layerY;
let obj = {x: x + 'px',y: y + 'px',showModal:false}
this.markerArr.push(obj);
},
//获取相对位置
getImgRect() {
setTimeout(() => {
// 元素点是相对 背景图定位的 拖拽点获得的做标是相对屏幕的距离
this.imgRect = document.querySelector(".plan-img .bg").getBoundingClientRect()
}, 30);
},
//移动位置
dragenter(e, item) {
const {x, y} = this.imgRect
if(e.clientX !==0 && e.clientY !==0) {
item.x = `${e.clientX - x}px`
item.y = `${e.clientY - y}px`
}

//提交关联设备
submitDev(){

//删除标记

切换自定义图标:
1.图例
这里我就不写具体功能实现js代码了,实现的思路是:
1.打开弹窗时必须要把markerArr置空并调用后台获取标点详情接口获取markerArr数据,下面组合数据可以参考
2.在标点选择关联的数据提交后,改变当前对象isDev属性为true切换图标样式并展示当前对象icon,下面HTML和CSS代码可以对比上文参考
3.如果当前对象的isDev已经为true,也可以切换另一条数据绑定Id进行重新绑定存入markerArr,这一步需要后台提供筛选数据的接口为基础,最后按后台保存接口参数要求筛选组合markerArr属性数据提交保存
2.代码
(1)组合数据
let arr=res.data
if(arr.length>0){
arr.forEach(item=>{
let obj={
deptId:item.deptId,
xcoordinate:item.xcoordinate?item.xcoordinate+'px':'',
ycoordinate:item.ycoordinate?item.ycoordinate+'px':'',
showModal:false,
isDev:true,
Id:item.Id,
devName:item.devName,
icon:item.icon
}
this.markerArr.push(obj)
})
}
(2)html

最近产品提了个做边界限制的需求,所以需要根据图标显示对按钮编辑框的显示位置进行动态变更

<span @click="deletePoit(index)">删除点位</span>
</div>
