添加事件的方式，定义一个函数，赋值给html元素的onXXX属性

1.js

<span class="single-line" onclick="toggleCornerBox(event,this)">品牌删选</span>
//显示酒店筛选
function toggleCornerBox(event,obj){
    console.log(event);
    
    if (window.event) {  
        event.cancelBubble=true;  
    } else {  
        //event.preventDefault();  
        event.stopPropagation();  
    }  

    $('.corner-box').css('display', 'none');
    $(obj).closest('.filter-btn-div').children('.corner-box').toggle();
}
