确认为真后，如何使用复选框clickall从表中删除所有条目？jqueryajaxphp
我正在尝试使用复选框从表中删除所有记录。当用户选中最上面的复选框时，它将选中循环中的所有其他复选框，然后会出现一个关于删除记录的确认框。如果用户单击“确定”，则将使用$.ajax删除所有记录；如果用户单击“取消”，则页面将返回到相同的状态，并且不再选中复选框确认为真后，如何使用复选框clickall从表中删除所有条目？jqueryajaxphp,php,jquery,ajax,checkbox,Php,Jquery,Ajax,Checkbox,我正在尝试使用复选框从表中删除所有记录。当用户选中最上面的复选框时，它将选中循环中的所有其他复选框，然后会出现一个关于删除记录的确认框。如果用户单击“确定”，则将使用$.ajax删除所有记录；如果用户单击“取消”，则页面将返回到相同的状态，并且不再选中复选框 <?php include 'dbconn.php'; ?> <table border="1" > <tr><td align="center" width

把这个放在你的if块中
$.ajax({
type: "GET",
url: '<php file which truncates table>',
success: function (data) {
if (data == 'truncated') {
alert('success');
} else {
alert('not truncated');
}
}
});
if(del==true){
$.ajax({
type: "POST",
url: 'your_file_url',
async:false,
cache: false,
success: function(data){
if (data == 1) {
alert('success');
} else {
alert('Error');
}
}
});
}
在您的php文件中，echo 1表示成功删除，0表示某些错误，这里是U-PageUrl，A-Action on-page，p-Parameter
if (confirm('Are you sure to delete this record?')) {
Operation(U, A, P);
}
function Operation(U, A, P) {
$.ajax({
type: "POST",
url: U + '/' + A,
data: P,
contentType: "application/json; charset=utf-8",
dataType: "json",
async: false,
cache: false,
success: function (r) {
var str = r.d;
}
});
}
您可以在HTML检查所有页面中使用类似的内容
<html>
<head><title>Select/Delete ALL with jQuery/PHP</title>
<script src="http://code.jquery.com/jquery-1.10.1.min.js"></script>
</head>
<body>
<table border="1" cellpadding="5">
<tr>
<th>
<input type="checkbox" id="checkAll" />
</th>
</tr>
<tr>
<td><input type="checkbox" class="check" name="posts[]" value="100" /></td>
</tr>
<tr>
<td><input type="checkbox" class="check" name="posts[]" value="200" /></td>
</tr>
<tr>
<td><input type="checkbox" class="check" name="posts[]" value="300" /></td>
</tr>
</table>
<script>
$(document).ready(function(){
var checked = false;
$('#checkAll').click(function(){
if (checked == false){
checked = true
} else {
checked = false
}
$('input.check').attr("checked",checked);
var confirmDelete=confirm("You checked all the box. Delete All?");
if (confirmDelete==true){
var csv = '';
$('.check').each(function() {
csv += $(this).attr("value") + ",";
});
$.ajax({
type: "POST",
url: "delete.php",
data: { tobeDeleted: csv }
}).done(function( msg ) {
console.log( "Data has been deleted: " + msg );
});
} else {
$('#checkAll').attr("checked", false);
$('input.check').attr("checked", false);
}
});
});
</script>
</body>
</html>
<?php
$postDeleted = substr($_POST['tobeDeleted'], 0, strlen($_POST['tobeDeleted'])-1);
$arrDeleted = explode(",", $postDeleted);
$sql = "DELETE FROM employee WHERE 1=1 ";
foreach($arrDeleted as $key=>$value){
$sql .= "OR employee_id = $value ";
}
echo $sql;
?>
嗨，谢谢你的回答，不过，请再读一遍我的问题。我的复选框功能好吗？我只是在学习jquery，我不知道我是否有正确的代码。更清楚你需要什么？我很肯定我的回答满足了你的问题。

$postDeleted = substr($_POST['tobeDeleted'], 0, strlen($_POST['tobeDeleted'])-1);
