Javascript Automated Click? - php

Question

I have the following function for a jquery login form and want to run it when php detects that the user is not logged in by echoing a javascript function that clicks the login button automatically
jq Code:
<script type="text/javascript">
$(document).ready(function() {
$('a.login-window, a.log').click(function() {
//Getting the variable's value from a link
var loginBox = $(this).attr('href');
//Fade in the Popup
$(loginBox).fadeIn(300);
//Set the center alignment padding + border see css style
var popMargTop = ($(loginBox).height() + 24) / 2;
var popMargLeft = ($(loginBox).width() + 24) / 2;
$(loginBox).css({
'margin-top' : -popMargTop,
'margin-left' : -popMargLeft
});
// Add the mask to body
$('body').append('<div id="mask"></div>');
$('#mask').fadeIn(300);
return false;
});
// When clicking on the button close or the mask layer the popup closed
$('a.close, #mask').live('click', function() {
$('#mask , .login-popup').fadeOut(300 , function() {
$('#mask').remove();
});
return false;
});
});
</script>
HTML
<div id="login-box" class="login-popup">
<img src="close_pop.png" class="btn_close" title="Close Window" alt="Close" />
<form method="post" method="post" name="f" id="f" class="signin" action="login.php">
<fieldset class="textbox">
<label class="username">
<span>Username or email</span>
<input id="username" name="username" value="" type="text" autocomplete="on" placeholder="Username">
</label>
<label class="password">
<span>Password</span>
<input id="password" name="password" value="" type="password" placeholder="Password">
</label>
<button class="submit button" type="submit" name="Submit" value="<?php echo $lang['LOGIN'];" style="background:none;">Sign in</button>
<p>
<a class="forgot" href="#">Forgot your password?</a>
</p>
</fieldset>
</form>
</div>

Answer 1

if you want to auto click a button, you are looking for .trigger
$('#some-id').trigger('click');
.trigger( 'event' ) explanation:
Execute all handlers and behaviors attached to the matched elements
for the given event type.
(as you are already using jQuery, hence)

Answer 2

<?php
if (!$lang['LOGIN']) {
echo '<script type="text/javascript">';
echo '$(function() {';
echo '$("a.login-window, a.log").trigger("click")';
echo '});';
echo '</script>';
}
?>

Answer 3

var loggedIn = isUserLoggedIn(); // check login status
if(!loggedIn){
$('a.login-window, a.log').trigger('click');
}
