    javascript - How to implement custom fallback function with input fields, text and submit button - Stack Overflow

    programmeradmin2浏览0评论

    I'm new to Dropzonejs and javascript/jQuery. I have spent some time playing with it and set up a dropzone which works great, but I need to create custom fallback function with 2 text inputs, 1 textarea, 1 checkbox and a submit button.

    I do not now what to do next after I have put 

    <div class="fallback"></div>

    into my form.

    I have also created:

    fallback: function() {

} // end of fallback

    in options.mydropzone

    Here is where I'm stuck. I need some hints to plete me custom fallback function.

    • A fallback from what, to what and when? – user2417483 Commented Sep 3, 2013 at 11:24
    • Sorry, when Browser does not support File API (drag&drop) I want to display a custom form e.g. IE9 users and safari < 6 do not get drag & drop form to submit. So I want to use fallback function in Dropzonejs and create custom upload form. – rafjon Commented Sep 3, 2013 at 11:35

    Dropzone actually does this out of the box, you do not need to create this behavior. You just have to place a div with class='fallback' within the form, that holds an input for older browsers:

      <form method="POST" action="/upload" class="dropzone">
    <div class="fallback">
      <input type="file" name="file" />
      <input type="submit" />
    </div>
  </form>

    Wrap your current form within a div

    <div id="generalForm">
<form name='form1' .....>
</div>

    Create a second form that you want to use as the fallback and wrap that in a div also

    <div id="specialForm" style='display:none'>
<form name="form1" .... >
</div>

    In your fallback function you would use

    fallback: function() {
  document.getElementById('generalForm').style.display="none";
  document.getElementById('specialForm').style.display='block';
}

    Is that what you are wanting?
