我有一个如下表:
<script>
$("#edit").hide(); // Hide the edit table first
$("#update").click(function() {
$("#edit").toggle();
$("#shown").toggle();
// If we are going from edit table to shown table
if($("#shown").is(":visible")) {
var vouchertype = $('input[name="vouchertype[]"]').map(function(){return $(this).val();}).get();
var mode= $('select[name="mode[]"]').map(function(){return $(this).val();}).get();
// Then add it to the shown table
var baseurl='<?php echo base_url()."index.php/account/insert_voucher";?>';
$.ajax({
type: "POST",
url: baseurl,
data: $('#edit *').serialize() ,
cache: false,
success: function(html) {
alert(html);
}
});
$(this).val("Edit");
}
else $(this).val("Update");
});
</script>
<table width="62%" height="70" border="1" cellpadding="0" cellspacing="0" class="tbl_grid" id="shown">

<?php
$rownum = 1;
foreach ($voucher_info as $eachrecord){
$zibracolor = ($rownum%2==0)?"even":"odd";
?>
<tr align="center" class="narmal">
<td height="25"><?php echo $eachrecord->voucher_id; ?></td>

<?php }
}
else {
echo "<tr class='bgcolor_02'>";
echo "<td align='center'><strong>No records found</strong></td>";
echo "</tr>";
}
?>

<?php } }

</td>

<input id="update" type="submit" name="submit" value="Edit"/
在第一个表中,我显示数据库中的值。但当用户点击表下方的编辑按钮时,该表的值应该是可编辑的。我已经成功地制作了可编辑的字段,但当用户再次点击提交时,更新后的值不会显示在第一个表中。我知道使用jQuery或JavaScript是可能的。当I alert(newsales)
时,警报未定义。
处理这一问题的一种简单方法是让两个单独的表,并在编辑表时在它们之间切换。例如,我们有一个表,显示了我们称为shown
的正常数据,以及一个包含input
和select
的表,供用户输入称为edit
的数据。这些表将共享同一个按钮,当单击时,它将在表之间切换,使其看起来像是在编辑和显示模式之间切换。这样,我们就可以将edit
表中的值复制到shown
表中的文本中。这里有一个例子:
$("#edit").hide(); // Hide the edit table first
$("#update").click(function() {
$("#edit").toggle();
$("#shown").toggle();
// If we are going from edit table to shown table
if($("#shown").is(":visible")) {
// Get the data from the edit table
var newSales = $("#edit tr:nth-child(1) td input[name='vouchertype']").val();
var newPay = $("#edit tr:nth-child(1) td select[name='mode']").val();
var newTax = $("#edit tr:nth-child(2) td select[name='tax']").val();
// Then add it to the shown table
$("#shown tr:nth-child(1) td:nth-child(2)").text(newSales);
$("#shown tr:nth-child(1) td:nth-child(3)").text(newPay);
$("#shown tr:nth-child(2) td:nth-child(1)").text(newTax);
$(this).val("Edit");
}
else $(this).val("Update");
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<table id="shown">
<tr>
<td>Sr no</td><td>Sales</td><td>Paid in</td>
</tr>
<tr><td>Taxed</td></tr>
</table>
<table id="edit">
<tr>
<td>Sr no</td><td><input type="text" name="vouchertype" value="Sales" /></td>
<td>
<select name="mode">
<option value="paidin">Paidin</option>
<option value="paidout">Paidout</option>
</select>
</td>
</tr>
<tr>
<td>
<select name="tax">
<option value="Taxed">Taxed</option>
<option value="Not Taxed">Not Taxed</option>
</select>
</td>
</tr>
</table>
<input id="update" type="submit" name="submit" value="Edit"/>
注意:这是对原始问题的回答,与作为编辑添加的新问题截然不同。
