Disable client-side validation in MVC 3 "cancel" submit button
提问by Glenn Doten
OK, been trying things for hours and could use some help. I'm trying to implement a page in MVC 3 that has "back" and "next" buttons. When the back button is clicked I want to disable client-side MVC validation from running so that my action method will run and send the user to the previous logical web page. I've tried this:
好的，已经尝试了几个小时，可以使用一些帮助。我正在尝试在 MVC 3 中实现一个具有“后退”和“下一个”按钮的页面。单击后退按钮时，我想禁用客户端 MVC 验证运行，以便我的操作方法将运行并将用户发送到上一个逻辑网页。我试过这个：
<script type="text/javascript">
document.getElementById("backButton").disableValidation = true;
</script>
and this:
和这个：
<input type="submit" name="backButton" value="← Back"
title="Go back to step 1." disableValidation="true" />
But no matter what, the cilent-side validation JavaScript kicks in and won't let the button do its post-back. I'm thinking that disableValidationonly works in MVC 2 perhaps, and I'm supposed to be doing something else in MVC 3, but cannot seem to find any examples.
但无论如何，客户端验证 JavaScript 会启动并且不会让按钮进行回发。我认为这可能disableValidation只适用于 MVC 2，我应该在 MVC 3 中做其他事情，但似乎找不到任何示例。

What is this mystical force that causes the answer to reveal itself as soon as you post a question somewhere?
是什么神秘力量让您在某处发布问题后立即显示答案？
It looks like in MVC 3 you disable client-side validation on a button by adding the class "cancel" to it. So in my example:
看起来在 MVC 3 中，您通过向按钮添加“取消”类来禁用按钮上的客户端验证。所以在我的例子中：
<input type="submit" name="backButton" value="← Back"
title="Go back to step 1." class="cancel" />
works great. And no ID attribute is needed either. If you have an actual style class on the button, just do this:
效果很好。也不需要 ID 属性。如果按钮上有实际的样式类，请执行以下操作：
<input type="submit" name="backButton" value="← Back"
title="Go back to step 1." class="style-name cancel" />

The validation scripts seem to be linked to the submit type input. By changing cancelto a button, validation is skipped:
验证脚本似乎链接到提交类型input。通过更改cancel为按钮，将跳过验证：
<button type="button" onclick="document.location.href('Index')">Cancel</button>

I know... very old question.. Yet it was the top of the search results when I looked.
我知道......很老的问题......然而，当我查看时，它是搜索结果的顶部。
For MVC 4 (and a BUTTON) it seems (at least for me) that the answer is simply adding the formnovalidate="formnovalidate"
对于 MVC 4（和一个 BUTTON），似乎（至少对我而言）答案只是添加formnovalidate="formnovalidate"
<button type="submit" class="btn btn-outline-success border-0" formnovalidate="formnovalidate" name="command" value="Back" title="Back">
<span class="fas fa-arrow-left" aria-hidden="true"></span>
Back
</button>

I use this for button
我用这个按钮
$("button").each(function (elem) {
var button = $($("button")[elem]);
button.addClass('cancel');
if (button.attr('type') == 'submit') {
button.click(function (e) {
var validator = button.closest('form').validate();
validator.cancelSubmit = true;
});
}
});
