layerui中如何点击表格行让复选选中并可以监听到复选框选中这个事件。

$(document).on("click",".layui-table-body table.layui-table tbody tr",function(){
    var obj = event ? event.target : event.srcElement;
    var tag = obj.tagName;
    var checkbox = $(this).find("td div.laytable-cell-checkbox div.layui-form-checkbox I");
    var dataIndex = $(this).attr("data-index");
    if($(this).parents(".layui-table-fixed").length>0){
        if(checkbox.length!=0){
            if(tag == 'DIV') {
                 checkbox.click();
            }
        }
    }else{
        var checkbox1=$(this).parents(".layui-table-body").next().find(".layui-table-body table.layui-table tbody tr[data-index="+dataIndex+"]").find("td div.laytable-cell-checkbox div.layui-form-checkbox I");;
        if(checkbox1.length!=0){
            if(tag == 'DIV') {
                checkbox1.click();
            }
        }
    }
});

$(document).on("click","td div.laytable-cell-checkbox div.layui-form-checkbox",function(e){
    e.stopPropagation();
});
