假设我有以下 HTML 表单:
<form>
...
<input type="submit" name="queue" value="Queue item">
<input type="submit" name="submit" value="Submit item">
</form>
我如何知道用户点击了哪个按钮(不使用 javascript)？
我查看了提交的数据，似乎当单击 "Queue Item" 时，"queue"= "Queue Item" 被发送到服务器。当 "Submit item" 被点击时，"submit"= "Submit item" 设置发送。
我可以依赖这种行为吗？它是否记录在 HTML 表单标准的某处？你们是怎么做到的？
最佳答案
是的，你可以依靠这个；它有完整的文档记录here .具体相关行说:
When a form is submitted for processing, some controls have their name paired with their current value and these pairs are submitted with the form. Those controls for which name/value pairs are submitted are called successful controls.
和
If a form contains more than one submit button, only the activated submit button is successful.
