layui 数据表格实现复选框单选功能的代码示例

//点击选中(单选)
//单击行勾选checkbox事件
  $(document).on("click",".layui-table-body table.layui-table tbody tr", function () {
    var index = $(this).attr('data-index');
    var tableBox = $(this).parents('.layui-table-box');
    //存在固定列
    if (tableBox.find(".layui-table-fixed.layui-table-fixed-l").length>0) {

    } else {
      tableDiv = tableBox.find(".layui-table-body.layui-table-main");
    }
    //获取已选中列并取消选中
    var trs = tableDiv.find(".layui-unselect.layui-form-checkbox.layui-form-checked").parent().parent().parent();
      for(var i = 0;i<trs.length;i++){
       var ind = $(trs[i]).attr("data-index");
       if(ind!=index){
       var checkCell = tableDiv.find("tr[data-index=" + ind + "]").find("td div.laytable-cell-checkbox div.layui-form-checkbox I");
        if (checkCell.length>0) {
