[RESOLVED] Input file styling

**FishGuy** · Mar 1st, 2011, 09:56 AM

Hi,

I have been trying to get this tutorial blog to work all day. So far I cannot get it to work and look as planned. Could someone show me a working example please.
http://www.quirksmode.org/dom/inputfile.html

I am using in in VS2010 in a aspx page

so far I have a cees file with this in it

Code:

form.example input:focus {
	background-color: transparent;

}
 
form.example div.fileinputs {
	position: relative;
	height: 30px;
	width: 280px;

}
 
form.example input.file {
	width: 300px;
	margin: 0;

		}
 
form.example input.file.hidden {
	position: relative;
	text-align: right;
	-moz-opacity:0 ;
	filter:alpha(opacity: 0);
	opacity: 0;
	z-index: 2;

}
 
form.example div.fakefile {
	position: absolute;
	top: 0px;
	left: 0px;
	width: 350px;
	padding: 0;
	margin: 0;
	z-index: 1;
	line-height: 90%;

}
And the aspx like this but it renders wrong 

	HTML Code:
	form.example div.fakefile input {
	margin-bottom: 5px;
	margin-left: 0;

}

HTML Code:

        fakeFileUpload.className = 'fakefile';
        fakeFileUpload.appendChild(document.createElement('input'));
        var image = document.createElement('img');
        image.src = '/images/buttons/browse.png';
        fakeFileUpload.appendChild(image);
        var x = document.getElementsByTagName('input');
        for (var i = 0; i < x.length; i++) {
            if (x[i].type != 'file') continue;
            if (x[i].parentNode.className != 'fileinputs') continue;
            x[i].className = 'file hidden';
            var clone = fakeFileUpload.cloneNode(true);
            x[i].parentNode.appendChild(clone);
            x[i].relatedElement = clone.getElementsByTagName('input')[0];
            x[i].onchange = x[i].onmouseout = function () {
                this.relatedElement.value = this.value;
            }
        }
    }

</script>

Well, the tutorial sets up a function, but the function is never called. You'll need to add something like:

Code:

window.onload = function(){
    initFileUploads();
}

Also, your markup shouldn't contain div.fakefile and its contents to begin with: those get generated automatically by the Javascript. All you should have is:

Code:

<div class="fileinputs">
  <input type="file" name="whatever"/>
</div>

Thanks, I have now got the javascript working but the formatting is not right, I have attached a pic of the items with the opacity only set to 60 so they are viewable. How do I get them to line up?

HTML Code:

<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<title></title>
<style type="text/css"> 
  form.example div.fileinputs {
	position: relative;
	height: 30px;
	width: 280px;

}
 
form.example input.file {
	width: 300px;
	margin: 0;

		}
 
form.example input.file.hidden {
	position: relative;
	text-align: right;
	-moz-opacity:0 ;
	filter:alpha(opacity: 60);
	opacity: 0;
	z-index: 2;

}
 
form.example div.fakefile {
	position: absolute;
	top: 0px;
	left: 0px;
	width: 350px;
	padding: 0;
	margin: 0;
	z-index: 1;
	line-height: 90%;

}
</style>

<script type="text/javascript">
    window.onload = function () {
        initFileUploads();
    }
    var W3CDOM = (document.createElement && document.getElementsByTagName);

    function initFileUploads() {
        if (!W3CDOM) return;
        var fakeFileUpload = document.createElement('div');
        fakeFileUpload.className = 'fakefile';
        fakeFileUpload.appendChild(document.createElement('input'));
        var image = document.createElement('img');
        image.src = '/images/buttons/browse.png';
        fakeFileUpload.appendChild(image);
        var x = document.getElementsByTagName('input');
        for (var i = 0; i < x.length; i++) {
            if (x[i].type != 'file') continue;
            if (x[i].parentNode.className != 'fileinputs') continue;
            x[i].className = 'file hidden';
            var clone = fakeFileUpload.cloneNode(true);
            x[i].parentNode.appendChild(clone);
            x[i].relatedElement = clone.getElementsByTagName('input')[0];
            x[i].onchange = x[i].onmouseout = function () {
                this.relatedElement.value = this.value;
            }
        }
    }

</script> 
</head>
 



<body>
   <form action="#" class="example">
<div class="fileinputs">
  <input type="file" name="whatever"/>
</div>
</form>




   
</body>
</html>

You can adjust properties (such as height, width, font-size) on form.example input.file.hidden until it's looking right. It doesn't need to line up precisely; if you make it big enough to cover your fake control, you could add "overflow: hidden" to form.example div.fileinputs to keep the click-area contained.

I can get the button and image to line up but not the image and the text box.

**FishGuy** · Mar 3rd, 2011, 07:33 AM

OK I figured it after using border to see what was what and adding absolute positioning to the img

HTML Code:

 /*Big container*/
#manualupload-fileupload-container div.fileinputs {
	position: relative;
	height: 50px;
	width: 500px;
margin: 0px 0px 0px 0px;
}
 /*
#manualupload-fileupload-container fileinputs.file {
	width: 350px;
border-color:green;
    border:5px;
border-style:solid;

		}
 */
 
 
 /*wraps hidden input control button and text components individually */
#manualupload-fileupload-container input.hidden {
	position: relative;
	text-align: right;
	-moz-opacity:0 ;
	filter:alpha(opacity: 0);
	opacity: 0.0;
	z-index: 2;
width:290px;
padding:5px;
}
 /*wraps fake input box and image button*/
 #manualupload-fileupload-container div.fakefile {
	position: absolute;

	top:0px;
	
	padding: 5;
	margin: 0;
	z-index: 1;
	line-height: 90%;



}

/*is fake input box*/
 #manualupload-fileupload-container div.fakefile input{
	position: absolute;
top:0px;

	width: 200px;
	padding: 5;
	margin: 0;
	z-index: 1;
	line-height: 90%;

}
#manualupload-fileupload-container div.fakefile img{
	position: absolute;
top:0px;

	left:210px;
	padding: 5;
	margin: 0;
	z-index: 1;
	line-height: 90%;

}
#manualupload-fileupload-container div.horizontal-panel container
{
    width:500px;
      border-color:Red;
    border:1px;
border-style:solid;

    }
