var files = document.getElementById("inputFile").files;
for(var i = 0 ; i < files.length; i++){
    console.log(files[i].size);
    console.log(files[i].type);
}

至于url，是readAdUrl那个么？

php:printr($FILES['image']);
js: var image = document.getElementById("image").files;
image.size
image.name
image.type
