javascript - Submit form using file input type -


I am using this code to upload a simple image file. 

  & lt; Form action = "upload.fp" method = "post" encrypt = "multipart / form-data" & gt; & Lt; Input type = "file" name = "file" onchange = "this.form.submit ();" /> & Lt; / Form & gt;

Then I have an upload.php file that is working very well. Now I want to use jQuery Post or Ajax to upload the image and want to show it on the screen without refreshing the page. I've changed the code for: 

  & lt; Form action = "" method = "post" enctype = "multipart / form-data" & gt; & Lt; Input type = "file" name = "file" /> & Lt; / Form & gt;

I have added it to my Javascript file: 

  $ ("form # formUpload"). Submit (function () {$ .post ('Upload.php', $ ("# formUpload"). Serialize (), function (data) {}) done (function () {});});

But nothing happens I know that I do not have the submitted input to enter the method which is the contents of the $ post. I tried with a trigger in a hidden submit button but nothing is working. Can anyone help solve it?

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...
