I am looking to create a system which on signup will create a subdomain on my website for the users account area.
You can try something like this instead.
ReplyDeleteI had the same problem.
ReplyDeleteBut i found out that the security restriction is only when the <input type="file"/> is set to display:none; or is visbilty:hidden.
So i tried positioning it outside the viewport by setting position:absolute and top:-100px; and voilà it works.
see http://jsfiddle.net/uPXNQ/
call it a hack.
Hope that works for you.
That's on purpose and by design. It's a security issue.
ReplyDeleteI managed with a simple $(...).click(); with JQuery 1.6.1
ReplyDeletethis worked for me:
ReplyDeleteJS:
$('#fileinput').trigger('click');
HTML:
<div class="hiddenfile">
<input name="upload" type="file" id="fileinput"/>
</div>
CSS:
.hiddenfile {
width: 0px;
height: 0px;
overflow: hidden;
}
>>>Another one that works Cross-Browser:<<<
The Idea is that you overlay an invisible huge "Browse" button over your custom button.
So when the user clicks your custom button, he's actually clicking on the "Browse" button of the native input field.
JS Fiddle: http://jsfiddle.net/5Rh7b/
HTML:
<div id="mybutton">
<input type="file" id="myfile" name="upload"/>
Click Me!
</div>
CSS:
div#mybutton {
/* IMPORTANT STUFF */
overflow: hidden;
position: relative;
/* SOME STYLING */
width: 50px;
height: 28px;
border: 1px solid green;
font-weight: bold
background: red;
}
div#mybutton:hover {
background: green;
}
input#myfile {
height: 30px;
cursor: pointer;
position: absolute;
top: 0px;
right: 0px;
font-size: 100px;
z-index: 2;
opacity: 0.0; /* Standard: FF gt 1.5, Opera, Safari */
filter: alpha(opacity=0); /* IE lt 8 */
-ms-filter: "alpha(opacity=0)"; /* IE 8 */
-khtml-opacity: 0.0; /* Safari 1.x */
-moz-opacity: 0.0; /* FF lt 1.5, Netscape */
}
JavaScript:
$(document).ready(function() {
$('#myfile').change(function(evt) {
alert($(this).val());
});
});
Try this, it's a hack. the Position:absolute is for Chrome and trigger('change') is for IE.
ReplyDeletevar hiddenFile = $("<input type=\"file\" name=\"file\" id=\"file1\" style=\"position:absolute;left:-9999px\" />");
$('body').append(hiddenFile);
$('#aPhotoUpload').click(function () {
hiddenFile.trigger('click');
if ($.browser.msie)
hiddenFile.trigger('change');
});
hiddenFile.change(function (e) {
alert('TODO');
});
