use

<div ref="imageWrapper"><div class="success"><div class="img"><img class="img-icon" src="../assets/success.png"/><p style="font-weight: 600; font-size: 18px">支付成功</p></div></div><div class="success-detail"><el-row style="margin-top: 10px;"><el-col :span="5" class="col-left-suc">收款商家</el-col><el-col :span="16" class="col-right">{{merchant}}</el-col></el-row><el-row style="margin-top: 10px;"><el-col :span="5" class="col-left-suc">费用名称</el-col><el-col :span="16" class="col-right">{{contName}}</el-col></el-row><el-row style="margin-top: 10px;"><el-col :span="5" class="col-left-suc">缴费金额</el-col><el-col :span="16" class="col-right">{{chargePrice}}元</el-col></el-row></div></div><div class="button"><el-button style="width: 70%;" type="success" size="small" @click="toImage">生成截图</el-button></div>

vue中用ref来指定你需要截屏的dom

toImage() {html2canvas(this.$refs.imageWrapper).then(canvas => {let dataURL = DataURL("image/png");this.imgUrl = dataURL;if (this.imgUrl !== "") {this.dialogTableVisible = true;}});}
