The page I am working on has a javascript function executed to print parts of the page. For some reason, printing in Safari, causes the window to somehow update. I say somehow, because it does not really refresh as in reload the page, but rather it starts the "rendering" of the page from start, i.e. scroll to top, flash animations start from 0, and so forth. The effect is reproduced by this fiddle: http://jsfiddle.net/fYmnB/ Clicking the print button and finishing or cancelling a print in Safari causes the screen to "go white" for a sec, which in my real website manifests itself as something "like" a reload. While running print button with, let's say, Firefox, just opens and closes the print dialogue without affecting the fiddle page in any way. Is there something with my way of calling the browsers print method that causes this, or how can it be explained - and preferably, avoided? P.S.: On my real site the same occurs with Chrome. In the ex
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');
});
