我可以自动提交文件上传吗? [英] Can I auto-submit a file upload?

问题描述

我希望不使用提交"按钮即可上传文件.我设法隐藏了文件上传按钮，但是我不确定在将文件添加到表单时是否可以隐藏提交"按钮并自动提交表单.能做到吗?

I would like to facilitate a file upload without a submit button. I've managed to hide the file upload button but I'm not sure whether it is possible to hide the submit button and also auto-submit the form when the file is added to the form. Can it be done?

我的代码是

  <form id="inputForm" role="form" class="marg-left" action="/admin/import" method="post" enctype="multipart/form-data">

        <input id="upload" name="file" type="file"/><a href="" id="upload_link"><div class="navigation-button">
            <div class="navigation-header">Import</div>
            <div class="navigation-desc">Import from tab-separated files on disk </div>
        </div>   </a>
            <input id="submit" type="submit" value="Submit" />
        </form>

CSS

#upload{
    display:none;
}

JavaScript

Javascript

$(function(){
    $("#upload_link").on('click', function(e){
        e.preventDefault();
        $("#upload:hidden").trigger('click');
    });

推荐答案

您需要监听 change 事件.

$("#upload:hidden").on('change', function(){
    $('#inputForm').submit();
});
