下午好,在我的 php/mysql 页面中,我有动态表,每行都有一行。我使用了显示/隐藏脚本来隐藏某些列,这很好,但我真的希望在隐藏列时更新行总数,在下面的示例中,如果我隐藏说 Jan 它应该扣除该列行中的值并更新总列?
这是js;
<script type="text/javascript" src="../js/prototype.js"></script>
<script language="javascript">
function toggleVis(button) {
// Toggle column
cells = $$('.t'+button.name);
cells.invoke(button.checked ? 'show' : 'hide');
// Recaulculate total
$$('tr.row').each(function(row) {
// Initialise to zero
var total = 0;
row.down('.total').textContent = total;
// Sum all visible cells
row.select('td').each(function(cell) {
total += cell.visible() ? parseInt(cell.textContent, 10) : 0;
});
// Write the total in the total cell
row.down('.total').textContent = total;
});
}
</script>
以及动态表格+表格隐藏列;
<form name="tcol" onsubmit="return false">
Show columns
<input type=checkbox name="col1" onclick="toggleVis(this.name)" checked> 1
<input type=checkbox name="col2" onclick="toggleVis(this.name)" checked> 2
<input type=checkbox name="col3" onclick="toggleVis(this.name)" checked> 3
</form>
<table border="1" cellpadding="1" cellspacing="1">
<tr>
<td class="tcol1">Adviser</td>
<td class="tcol2">Jan</td>
<td class="tcol3">Feb</td>
<td class="total">Total</td>
</tr>
<?php do { ?>
<tr class="row">
<td class="tcol1"><?php echo $row_Recordset1['Adviser']; ?></td>
<td class="tcol2"><?php echo $row_Recordset1['Jan' ]; ?></td>
<td class="tcol3"><?php echo $row_Recordset1['Feb' ]; ?></td>
<td class="total"><?php echo $row_Recordset1['Total' ]; ?></td>
</tr>
<?php } while ($row_Recordset1 = mysql_fetch_assoc($Recordset1)); ?>
</table>
非常感谢您的关注。。
