Question

我有一个计数器，根据计数器的内容向表中添加行数。我有一个按钮，每次单击时都会增加计数器，但它只能运行一次。

PHP：

if (isset($_REQUEST['Addmore'])) {      
    $NoOfUsers++;

<form action="addstudent.php">
<th>
    <button type="submit" class="btn btn-default btn-sm spoiler-trigger pull-right" aria-label="Left Align" name="Addmore" title="Add Row">
        <span class="glyphicon glyphicon-thumbs-up" aria-hidden="true"> </span>
    </button>
</th>
</form>

Answer 1

<强> PHP

<?php
session_start();
if (isset($_REQUEST['Addmore'])) {
?><button class="btn btn-default"><?php
echo $_SESSION['NoOfUsers'] ? ++$_SESSION['NoOfUsers'] : $_SESSION['NoOfUsers']=1;
?></button><?php
}

或 JavaScript

<button id="counter" class="btn btn-default">0</button>
<script>
    $('#counter').on('click',function(){$( this ).html(1 * $( this ).html() + 1)});    
</script>
