显示预览文件

It is that I need to send a preview of an image in a div in specific, taking the route of the image stored in the database and for this run a successful Ajax send the image.

success: function(respuesta) {
           var preview = document.getElementById("archivoRadicado").value = respuesta;
           $('#vistaPrevia').innerHTML = '<embed src="'+preview +'"/>';
       },
error: function(xhr,err) { 
           alert("Error");
       }

And the <embed /> html control the path to receiving the route but I did not get anything, no errors or éxtito, I can do or have mistake?

This is where you should go div preview

<div id="vistaPrevia" style="width=100%; height:490px;">    

</div>

You have to be sure you write CLEAN code. For starters, the following line is not valid.

<div id="vistaPrevia" style="width=100%; height:490px;">    

Secondly, you're mixing up jquery and javascript. Stick to one, either jquery or javascript, since you have to initiate either one or the other, I believe, at least to my understanding, that you mustn't mix languages like this. If you decide to use jquery, change this line...

$('#vistaPrevia').innerHTML = '<embed src="'+preview +'"/>';

...to this

$('#vistaPrevia').html('<embed src="'+ preview +'"/>');

Hope this helps.
