This is my HTML:

<input type="file" id="browse" name="browse" size=""  placeholder="Photo" checked="checked" class="upload"/>
<input type="button" onclick="javascript:onbrowse()"  class="unknown" value=""/>

And my JavaScript:

$(function() {
        $(".upload").change(function () {
            var fileObj = $(this).get(0);
            var fileName;
            if (fileObj.files) {
                fileName = fileObj.files.item(0).getAsDataURL()
            } else {
                fileName = fileObj.value;
            }
            $(".unknown").css("background-size", "100px 100px");
            $(".unknown").css("background-image", "url(" + fileName + ")");
        });
    });

    function onbrowse() {
        document.getElementById('browse').click();
    }

I have two problems:

1. onclick doesn't work in Chrome and

2. getAsDataURL() doesn't work in Chrome and IE

Can you help me?

IE does not yet support the File API. Anyhow, you need to use a FileReader to read a file. Also, the file is not its file name (your variable naming is a little ambiguous).

The click delegation to the file input works just fine.

http://jsfiddle/fKQDL/

file = fileObj.files[0];
var fr = new FileReader;
fr.onloadend = changeimg;
fr.readAsDataURL(file);

Bind the button's behavior with jQuery

jQuery('input[type="button"].unknown').click ( onbrowse );
