trigger click problem on isset (Php, jquery, iframe)
I am having a small problem and i don`t know the reason. I set that
1- If you click Print button then print.php page will be printed automatically.
2- if you submit a form then print.php page will be printed automatically.
Problem is on second option. Page gets printed automatically perfect but if i click Print button again it does not print the page again.
I am using firefox.
<script language="javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.3.2/jquery.min.js"></script>
<script type="text/javascript">
function loadiFrame(src)
{
$("#iframeplaceholder").html("<iframe id='myiframe' name='myname' src='" + src + "' frameborder='0' vspace='0' hspace='0' marginwidth='0' marginheight='0' width='1' scrolling='no' height='1' />");
}
$(function()
{
$("#printbutton")开发者_如何学编程.bind("click",
function() {
loadiFrame('print.php');
$("#myiframe").load(
function() {
window.frames['myname'].focus();
window.frames['myname'].print();
}
);
}
);
});
</script>
<?
if (isset($_POST['formSubmit']))
{
echo "form submitted";
?>
<script type="text/javascript">
$(document).ready(function(){
$('#printbutton').trigger('click');
});
</script>
<? } ?>
</head>
<body>
<table border="1">
<tr>
<td><input type="button" id="printbutton" value=" Print " /><div id="iframeplaceholder"></div></td>
</tr>
</table>
<form action="auto.php" method="post">
<input name="formSubmit" type="submit" value="Submit" />
</form>
</body>
you should call loadiFrame function only if the iframe doesn't exist.
$(function()
{
$("#printbutton").click(
function() {
if($('#myiframe').length==0){
loadiFrame('print.php'); }
$("#myiframe").ready(
function() {
window.frames['myname'].focus();
window.frames['myname'].print();
});
});
});
Try it now.
Good luck :)
it's a bug in Firefox. It works if you add a counter that makes each iframe name unique.
