javascript - Preview image before upload with Carrierwave -


I have a form where the user can create a new picture I have done it successfully with carrier usage. I was thinking that Is it possible to preview the image selected in the browser before uploading? I have made some efforts with javascript but have not worked for me.

This is the code for image uploading with CarrierView: 

   photo =: html = & gt; {: Multipurpose = & gt; True} what? F | & Gt%; & Lt;% = f.file_field: Image% & gt; & Lt; Div class = "field" & gt; & Lt;% = f.label: name% & gt; & Lt; Br> & Lt;% = f.text_field: name% & gt; & Lt; / Div & gt; & Lt; Div class = "field" & gt; & Lt;% = f.label: Details% & gt; & Lt; Br> & Lt;% = f.text_area: Details% & gt; & Lt; / Div & gt; & Lt; Div class = "verb" & gt; & Lt;% = f.submit "Save Photo"% & gt; & Lt; / Div & gt; & Lt;% end% & gt;

My goal is to have a small thumbnail of the image so that users can view it before uploading. I'm guessing that I can not use rail here because it can only be for server side ...

Any ideas? :)

If you are using Bootstrap 3 then there is a great extension for it

ios - How do I use CFArrayRef in Swift? -

Unmanaged & lt; Cfarray & gt; also means? I looked, but I do not need to change the array in a fast array (though it would be good). I need to be able to get value from the array. I also tried CFArray method to pass in a function: func doSomeStuffOnArray (myArray: NSArray) {} Although I get the same error when using: doSomeStuffOnArray (cfArr); // unmanaged & lt; CFArray & gt; I am using CFArray because I want to sto...
