按钮据右边边框距离设置：

document.getElementsByClassName('uni-btn-icon')[2].style.marginRight = '22px'

监听按钮状态：

onNavigationBarButtonTap(e) {
    			if (e.index === 1|| e.index === 2) {
    				this.isfilter = !this.isfilter
    				if (this.isfilter == false) {
    					document.getElementsByClassName('uni-btn-icon')[3].innerText = '筛选';
    					document.getElementsByClassName('uni-btn-icon')[2].style.color = '#333333'
    					document.getElementsByClassName('uni-btn-icon')[3].style.color = '#333333'
    				} else {
    					document.getElementsByClassName('uni-btn-icon')[3].innerText = '已筛选';
    					document.getElementsByClassName('uni-btn-icon')[2].style.color = '#E86951'
    					document.getElementsByClassName('uni-btn-icon')[3].style.color = '#E86951'
    				}
    			}else if(e.index == 0){
    				uni.switchTab({
    					url
    				})
    			}
    			
    		}
