我尝试停止多个提交按钮。我是php和javascript的新手。我确实尝试了很多不同的堆栈溢出答案选项。我确实检查了会话令牌,但它对我不起作用,因为我从JavaScript提交表单。您可以看到禁用代码按钮。当我点击按钮它被禁用并形成提交但它没有达到btn付费的PHP代码。请帮忙。
php code1:
<?php
include('sessionstart.php');
include('session.php');
include('processtransaction.php');
?>
<script src="js/mytransaction.js"></script>
php code1将调用javascript并且javascript具有表单提交。如果表单已提交,则禁用/(会话令牌处理)已支付的按钮,它应该调用btn-paid的代码。
javascript代码mytransaction:
$(document).ready(function() {
var table = $('#myTransactionitems').dataTable(); //Initialize the datatable
var user = $(this).attr('id');
if(user != '')
{
$.ajax({
url: 'transactions',
dataType: 'json',
success: function(s){
console.log(s);
table.fnClearTable();
for(var i = 0; i < s.length; i++) {
var disp1 = '';
if (s[i][4] != 'Reserved') {
disp1 = 'display:none;'
}
table.fnAddData([
"<form method='post' action='reservationdetails'><input name = 'transactionid' type='hidden'\
value='"+s[i][0]+"'></input><input type='submit' id = 'btn-bank' name='btn-bank' value = '"+s[i][0]+"' class='btn btn-link'>\
</input></form>",
s[i][1],
s[i][2],
s[i][3],
s[i][4],
s[i][5],
"<form method='post'><input name = 'transactionid' type='hidden'\
value='"+s[i][0]+"'><input name = 'donationid' type='hidden'\
value='"+s[i][2]+"'><input name = 'splitamount' type='hidden'\
value='"+s[i][3]+"'></input></input><input type='submit' id = 'btn-paid' name='btn-paid' value = 'Paid' onclick='this.disabled=true;this.form.submit();' style='" + disp1 +"' class='btn btn-sm btn-success pull-left '>\
</input></form><form method='post'><input name = 'transactionid' type='hidden'\
value='"+s[i][0]+"'><input name = 'donationid' type='hidden' \
value='"+s[i][2]+"'><input name = 'splitamount' type='hidden'\
value='"+s[i][3]+"'></input><input type='submit' id = 'btn-cancel' name='btn-cancel' value = 'Cancel' onclick='this.disabled=true;this.form.submit();' style='" + disp1 +"' class='btn btn-sm btn-danger pull-right'>\
</input></form>"
]);
} // End For
},
error: function(e){
console.log(e.responseText);
}
});
}
});
php code2 processtransaction:
<?php
if (isset($_POST['btn-paid'])) {
require_once("dbcontroller.php");
$db_handle = new DBController();
$conn = $db_handle->connectDB();
$query = "update MYTRANSACTION set STATUS =? where DONATION_ID=? AND ID=?";
$stmt = $conn->prepare($query);
$stmt->bind_param("sii",$status,$donation_id, $transaction_id);
$stmt->execute();
$stmt->close();
$db_handle->closeDB($conn);
}
?>

如果你想阻止用户在页面加载之前点击两次(导致2个帖子),最好使用javascript。由于您已经在使用jQuery,因此可以执行以下操作:
$("input[type='submit']").click(function(e) {
e.preventDefault(); // Prevent the page from submitting on click.
$(this).attr('disabled', true); // Disable this input.
$(this).parent("form").submit(); // Submit the form it is in.
});
编辑:
为了满足在页面加载之前立即提交的人(即在加载JS之前),您可以进行以下更改。
在HTML表单中,将“禁用”添加到“提交”按钮:
<input type="submit" value="Submit" disabled />
将您的JS更改为以下内容:
$("input[type='submit']").attr('disabled', false); // Enable this input.
$("input[type='submit']").click(function(e) {
e.preventDefault(); // Prevent the page from submitting on click.
$(this).attr('disabled', true); // Disable this input.
$(this).parent("form").submit(); // Submit the form it is in.
});
这样做会使提交按钮被禁用,直到JS加载完毕。一旦JS加载,它将启用提交按钮,然后剩余的东西将像以前一样工作。
