easyui扩展行默认展开 以及 去除滚动条

Posted 2021-01-06 yigexiaojiangshi

 问题背景：

在做打印页面的时候，要求有详细的默认展开显示。 

 

遇到的问题：

1）在用扩展行的时候，grid的所有行都添加了展开收起的图标，（第二行没有明细）如下

 

 2）默认展示有详细行的时候，内容被滚动条遮挡（影响打印）

 

 

 3） 解决方法：在easyui扩展行的 onLoadSuccess 函数里进行处理 

  1 $list.datagrid({
  2     view: detailview,
  3     onLoadSuccess: function (data) {
  4 
  5         //没有详细的行 去掉 展示收起图标
  6         for (var i = 0; i < data.rows.length; i++) {
  7             if (data.rows[i].FeeCategoryID != 1) {
  8                 var expander = $(‘body‘).find(‘tr.datagrid-row[datagrid-row-index=‘ + i + ‘]‘);
  9                 expander.children(‘[field="_expander"]‘).html(‘‘);
 10             }
 11         }
 12 
 13         //默认展开所有详细行
 14         var row = $list.datagrid("getRows");
 15         for (var r = 0; r < row.length; r++) {
 16             $list.datagrid("expandRow", r);
 17         }
 18 
 19         //去除滚动条
 20         var $ScrH1 = $(‘.datagrid-view1 .datagrid-body‘);
 21         var $ScrH2 = $(‘.datagrid-view2 .datagrid-body‘);
 22         $ScrH1.height($ScrH2[0].scrollHeight);
 23         $ScrH2.height($ScrH2[0].scrollHeight);
 24         $(‘.datagrid-view‘).height($(‘.datagrid-view2‘).height());
 25     },
 26     detailFormatter: function (index, row) {

 28             return ‘<div class="datail-item-wrap" style="padding:5px 0"></div>‘;
 29         }
