在 input type=“submit” 按钮中添加事件

如下代码，可以直接在<input type="submit" ..>中添加onclick事件。用户点击"submit"按钮后会触发两个操作：一是提交表单到后台服务器。二是触发onClick事件调用我自己定义的upLoadData()函数。

​

<form action="http://127.0.0.1:5000" method="post" >

<div class="form-group label-floating" style="padding:0px;">

<label for="desc" class="control-label">Describe the image in as much detail as possible...</label>

<textarea id="desc" name="desc" class = "textarea_personal" rows="17" cols="50"></textarea>

</div>

<input type="submit" value="提交" name="submit" onclick="upLoadData()">

</form>
