我已经确认本地存储使用

sessionStorage.setItem(rowId, 'true');

当页面刷新时，我尝试将css.selected类名重新应用到行ID
主要目的是在重新加载页面时保持选中的行突出显示
x一个一个一个一个x一个一个二个x

--Java函数，点击时高亮显示表格行，并将行ID存储在sessionStorage.setItem中（rowId，'true'）;

<script type="text/javascript">
highlight_row();
function highlight_row() {

    var table = document.getElementById('display-table');
    var cells = table.getElementsByTagName('td');

    for (var i = 0; i < cells.length; i++) {
        // Take each cell
        var cell = cells[i];
        // do something on onclick event for cell
        cell.onclick = function () {
            // Get the row id where the cell exists
            var rowId = this.parentNode.rowIndex;
            var rowsNotSelected = table.getElementsByTagName('tr');
            for (var row = 0; row < rowsNotSelected.length; row++) {
                rowsNotSelected[row].style.backgroundColor = "";
                rowsNotSelected[row].classList.remove('selected');
            }
            var rowSelected = table.getElementsByTagName('tr')[rowId];
            rowSelected.style.backgroundColor = "yellow";
            rowSelected.className += " selected";
    
            sessionStorage.setItem(rowId, 'true');
            //alert(rowId);   
            
        }
    }

}
</script>
