单击PHP后禁用按钮

Question

How can I disable a button after it has been clicked. And let it remain disabled. I tried using .prop('disabled', true); although it disables the button, however when i refresh the page then button became clickable again. Also if I have a list of it, it would disable other button as well which I do not want. Is there anyway to do it?

<table>
<tr>
<td id="milestone_1"> 
</td>
<td id="percentage_1">
</td>
<td>
<form id="pay1">
<input type="hidden" class="id_hidden" name="id_hidden">
<input type="hidden" class="paid_hidden" name="paid_hidden">
<input type="hidden" class="budget_hidden" name="budget">
<input type="hidden" id="percent1" name="percent">
<input type="submit" name="pay1" value="Pay">
</form>
</td>
</tr>

<tr>
<td id="milestone_2">
</td>
<td id="percentage_2">
</td>
<td>
<form id="pay2">
<input type="hidden" class="id_hidden" name="id_hidden">
<input type="hidden" class="paid_hidden" name="paid_hidden">
<input type="hidden" class="budget_hidden" name="budget">
<input type="hidden" id="percent2" name="percent">
<input type="submit" name="pay2" value="Pay">
</form>
</td>
</tr>

<tr>
<td id="milestone_3">
</td>
<td id="percentage_3">
</td>
<td>
<form id="pay3">
<input type="hidden" class="id_hidden" name="id_hidden">
<input type="hidden" class="paid_hidden" name="paid_hidden">
<input type="hidden" class="budget_hidden" name="budget">
<input type="hidden" id="percent3" name="percent">
<input type="submit" name="pay3" value="Pay">
</form>
</td>
</tr>

</table>


$("#pay1").submit(function(){
    $.ajax({
        type: "GET",
        url: "pay.php",
        data: $("#pay1").serialize(),
        success: function(data){

            $("#add_success").html(data);
            $("#add_err").html("");

        }
    });
    return false
});
$("#pay2").submit(function(){
    $.ajax({
        type: "GET",
        url: "pay.php",
        data: $("#pay2").serialize(),
        success: function(data){

            $("#add_success").html(data);
            $("#add_err").html("");

        }
    });
    return false
});
$("#pay3").submit(function(){
    $.ajax({
        type: "GET",
        url: "pay.php",
        data: $("#pay3").serialize(),
        success: function(data){

            $("#add_success").html(data);
            $("#add_err").html("");

        }
    });
    return false
});

Answer 1

I suggest to you use cookie to keep user state or data.
simply you can use cookie in pure javascript by document.cookie object,

javascript create cookie sample code:

document.cookie="username=John Doe; expires=Thu, 18 Dec 2013 12:00:00 GMT; path=/";

read cookie:

var x = document.cookie;

also you can use this jQuery plugin for handle that

cookie are very handy in PHP, so you can access cookie data by $_COOKIE global php variable.
Personally i recommend you to keep tag selector in javascript variable and disable them on dom ready for other later requests.

UPDATE

For more secure implementation you can use server-side solutions, for this case you can use PHP session to keep data for showing or not showing elements to user.
