抱歉一直有问题!!我有一个表格,显示我的数据库中的数据记录。为了让生活更轻松,我使用 jquery 使其可编辑,以便用户可以立即单击右侧区域进行编辑,而无需重定向到不同的页面。几个问题..我如何改进下面的代码,以便当点击表格上带有复选框和链接的区域时,它不会响应/不可编辑?此外,编辑功能目前无法完全正常工作,我在试图找出问题所在时遇到了问题。该表响应下面 jquery 中定义的所有内容,但不更新我的数据库。
有我的jQuery代码edit.js
$(function() {
$('tbody').on('click','td',function() {
displayForm( $(this) );
});
});
function displayForm( cell ) {
var column = cell.attr('class'),
id = cell.closest('tr').attr('id'),
cellWidth = cell.css('width'),
prevContent = cell.text()
form = '<form action="javascript: this.preventDefault"><input type="text" name="newValue" value="'+prevContent+'" /><input type="hidden" name="id" value="'+id+'" />'+'<input type="hidden" name="column" value="'+column+'" /></form>';
cell.html(form).find('input[type=text]')
.focus()
.css('width',cellWidth);
cell.on('click', function(){return false});
cell.on('keydown',function(e) {
if (e.keyCode == 13) {//13 == enter
changeField(cell, prevContent);//update field
} else if (e.keyCode == 27) {//27 == escape
cell.text(prevContent);//revert to original value
cell.off('click'); //reactivate editing
}
});
}
function changeField( cell, prevContent ) {
cell.off('keydown');
var url = 'edit.php?edit&',
input = cell.find('form').serialize();
$.getJSON(url+input, function(data) {
if (data.success)
cell.html(data.value);
else {
alert("There was a problem updating the data. Please try again.");
cell.html(prevContent);
}
});
cell.off('click');
}
在我的edit.php中,我有以下内容:
<?php
include ("common.php");
if (isset($_GET['edit'])){
$column = $_GET['column'];
$id = $_GET['id'];
$newValue = $_GET["newValue"];
$sql = 'UPDATE compliance_requirement SET $column = :value WHERE ComplianceID = :id';
$stmt = $dbh ->prepare($sql);
$stmt->bindParam(':value', $newValue);
$stmt->bindParam(':id', $id);
$response['success'] = $stmt->execute();
$response['value']=$newValue;
echo json_encode($response);
}?>
最后是我的html ..
<div class="compTable">
<table>
<thead><tr><th>Compliance Name</th><th>Compliance Goal</th><th>Compliance Description</th><th>Opions</th><th>Invite</th></tr></thead>
<tbody>
<?php
$sql = 'SELECT * FROM compliance_requirement';
$results = $db->query($sql);
$rows = $results->fetchAll();
foreach ($rows as $row) {
echo '<tr id="'.$row['ComplianceID'].'">';
echo '<td class="crsDesc">'.$row['ComplianceName'].'</td>
<td >'.$row['ComplianceGoal'].'</td>
<td >'.$row['ComplianceDescription'].'</td>
<td ><a href =inviteObstacle.php?action=invite&id=name1> InviteObstacle </a></td>
<td style="text-align: center; vertical-align: middle;"> <input type="checkbox" name="query_myTextEditBox">
</td>';
echo '</tr>';
}?>
</tbody>
</table>
</div>
非常感谢您的帮助。提前致谢
