[jQuery] Getting value of input type="file"

[jQuery] Getting value of input type="file"


I am using ajax to post a form that has an image upload input field.
I tried getting the value as I do with other inputs, but it does not
seem to work, and returns undefined:
var imageUpload = $("#image_0").val();
<input type="file" name="image_0" class="sq-form-field" />
Am I missing something here?
