JS script processing (using ajax technology)
First determine whether There is no selected value. If there is no value, it will prompt; if there is, it will be passed to the server for processing

/* 批量删除 */
  // 全选
  $(&#39;.all&#39;).click(function() {
    if($(this).is(&#39;:checked&#39;)) {
      $(&#39;:checkbox&#39;).attr(&#39;checked&#39;, &#39;checked&#39;);
    } else {
      $(&#39;:checkbox&#39;).removeAttr(&#39;checked&#39;);
    }
  });

  // 删除操作
  $(&#39;#discard&#39;).click(function() {
    if($(&#39;:checked&#39;).size() > 0) {
      layer.confirm(&#39;确定要删除吗？&#39;, {
        btn: [&#39;确定&#39;,&#39;取消&#39;], //按钮
        shade: false //不显示遮罩
      }, function(){
        $.post("{:U(&#39;Single/discard&#39;)}", {data: $(&#39;form&#39;).serializeArray()}, function(res) {
          if(res.state == 1) {
            layer.msg(res.message, {icon: 1, time: 1000});
          } else {
            layer.msg(res.message, {icon: 2, time: 1000});
          }
          setTimeout(function() {
            location.reload();
          }, 1000);
