在画布处添加点击事件

 <div id="icanvas" style="list-style:none;background:white;width:100px" v-html="D_program" @click="getDivE" >{{D_program}}</div>

点击事件如下

getDivE(event){
     console.log(event.target)
     console.log(event.target.src)
     this.netImg = event.target.src
     console.log($(event.target).parent().parent().data("id"))
     this.imgfatId = $(event.target).parent().parent().data("id")
      // var imgFendId = $(event.target).parent().parent().data("id")
      // console.log(imgFendId+'')
      $('.active:not(li)').removeClass('active')
      $(event.target).addClass('active')
            },

替换事件

var _this = this
                // console.log(event)
                console.log(event.FilePath)
                _this.netImg = event.FilePath
                var uesImgList = _this.userSrcimg
                var FaimgID = _this.imgfatId
                this.netImg = event.FilePath;
                console.log( $(".active:not(li)"))
                $(".active:not(li)").attr('src',event.FilePath)
