The documentation says: The File interface's non-standard methods getAsBinary(), getAsDataURL(), and getAsText() have been removed as well as the non-standard properties fileName and fileSize. See:

image preview working for me please find code......
var reader = new FileReader();
function preview(what) { if(jQuery.browser.msie || jQuery.browser.safari || jQuery.browser.chrome) { document.getElementById("preview-photo").src=what.value; return; } else{ // array with acceptable file types var accept = ["image/png","image/jpeg","image/jpg","image/gif"];
// if we accept the first selected file type if (accept.indexOf(what.files[0].type) > -1) { if(what.files && what.files[0]){ reader.readAsDataURL(what.files[0]); document.getElementById("preview-photo").src=reader.result; } } } }
