uniapp中获取dom元素宽度、高度

 let info = uni.createSelectorQuery().select(".info-box");
                    info.boundingClientRect(function(data) { //data - 各种参数
                        //readonly bottom: number;
                        // readonly height: number;
                        // readonly left: number;
                        // readonly right: number;
                        // readonly top: number;
                        // readonly width: number;
                        // readonly x: number;
                        // readonly y: number;
                        that.setWebviewHeight(parseInt(data.height))
                        console.log('元素高度为--->>',parseInt(data.height)) // 获取元素宽度
                    }).exec()
