Question

how can i use the variable from my php-sql to become the message for my javascript alert?

heres my code

<?php

    $select = "SELECT * FROM post";
    $result = mysql_query($select) or die("couldn't select table");


    while ($rows = mysql_fetch_array($result))
    {
        echo"<input type='button' class=term onclick='return terms()' value=Terms >";

        echo"<input type='hidden' value='$rows[terms]' id='term' name='term'>";
    }
?>  

<script language="JavaScript">
    function terms() 
    {
        var readers = document.getElementById("term"); 
        alert(readers.value);
    }
</script>

It works, the alert message displays. But I got the problem on displaying the right message for specific fetch of row. All got the same message (message from the first row).

I tried to use getElementByName but the alert doesn’t pop-up,
so i dont have to try making the input name=”term[]” ——–(into its array form)

Help please!

I think it will be find if you change this line of script

 echo"<input type='button' class=term onclick='terms()' value=Terms >";

onclick=’terms()’ here, instead of onclick=’return terms()’

EDIT:

<?php   echo"<input type='button' class=term onclick='terms(this)' data-result ='". $rows['terms'] ."' value=Terms >"; ?>
      /* Remove the hidden field */
<script language="JavaScript">
    function terms(e) 
    {
        var readers = e.getAttribute('data-result'); 
        alert(readers);
    }
</script>
