没有类型提交的按钮提交表单
button submitting form without type submit
我有这个:
<form action="/newPost" method="POST" style="max-width:450px; margin:50px auto;">
<a href="/media">See Current Posts</a>
<input name="postTitle" type="text" class="f-input" placeholder="Subject">
<input name="socialLink" type="text" class="f-input" placeholder="Social Link">
<textarea name="postDescription" class="f-input" placeholder="Type a message"></textarea>
<input type="text" name="url" id="url" required readonly>
<button id="upload_widget" class="button">Upload Photo</button>
<br>
<br>
<button type="submit" value="Send">Send</button>
</form>
然而,当我点击这个<button id="upload_widget" class="button">Upload Photo</button>
按钮时,它实际上提交了表单,但是,我没有定义type=submit
!!!它不应该提交表单,除非它作为类型提交。我错了吗?我该如何解决这个问题?
The missing value default and invalid value default are the Submit Button state.
<button>
元素的默认 type
是 submit
。
如果你想让它只触发 JavaScript 那么你必须 明确地 将它设置为 type="button"
.
