如何弹出一个带有文本框的javascript警告框来更新mysql表？ [关闭]

Question

I'm making a site that lets people login, buy stuff from the store, etc, I am trying to make it where moderators can change and update their credits by clicking a link and make a popup alert box thing pop up saying to type in how many credits to give them in the popup box, then click "Ok" and update the mysql table with the new amount, how can I do this?

For this you have to use JavaScript's prompt function which provides a text box to enter value after getting the value from the user you can make an ajax request to sever to update the new amount in the database.

Something like this:-

First add jQuery file in your page.

<a href="javascript:void(0);" onClick="updateAmount(itemId);">Click here to update amount</a>
<script>
    function updateAmount(itemId){
        amount = prompt('Enter new amount', 0);
        $.ajax({
            url: updateAmount.php,
           data: {"amount": amount, "id": itemId},
           success: function(data){
               alert("Amount updated successfully.");
           }
        });
    }
</script>
