First, i have a code that i need to know if the user has clicked on one submit button, then, i need one function to enable another submit button that is disabled by disabled="disabled".

Here's my noob function (Needs improves, does not work). :

<script>
    function EnableSend() {
    if(document.getElementById("Submit_Facebook").click(); {
    document.getElementById("submit").disabled = false; }
    }
 </script>

And now the code:

1 - Disabled Submit: (Will be enabled after user click on Submit_Facebook submit button).

<input id="submit" name="submit" type="submit" value="" disabled="disabled">

2 - Other submit that will make the disabled submit enabled.

<form method="post" class="button" action="<?=$PHP_SELF;?>"">
 <input id="Submit_Facebook" name="Submit_Facebook" type="submit" value=""onclick="EnableSend()">
</form>

3 - Php part

<?php
if (isset($_POST['Submit_Facebook'])) {
echo "<script>alert('You now can proceed to step two.');</script>";
echo '<script type="text/javascript"language="javascript">window.open("#");</script>'; 
exit;
}?>

Well, my english is not that good, but if you guys need any detail just contact me, thanks for your attention.

• 1 what are you doing in that function looks weird – Susheel Singh Commented May 19, 2014 at 18:43
• the .click() in javascript simulates a mouse click, not to be confused with jQuery's click method which attaches an event listener. So wrapping it in a if won't really help you here. – Ballbin Commented May 19, 2014 at 18:49
• @Jack_of_All_Trades - If removes the semicolon the OP will still have a broken if statement. They would have to replace ';' with ')'. – Ballbin Commented May 19, 2014 at 18:50
• @Ballbin: yes, you are right. – Jack_of_All_Trades Commented May 19, 2014 at 18:51

<input id="submit" name="submit" type="submit" value="send" disabled="disabled">   
<input id="Submit_Facebook" name="Submit_Facebook" type="submit" value="" onclick="EnableSend();">

<script type="text/javascript">
function EnableSend() {
    document.getElementById("submit").disabled = false;
}
</script>

You got to remove disabled attribute from input.

Something like this:

var EnableSend = function(){
  $( "#submit" ).removeAttr('disabled');
};
