Button does not specify type as submit. Clicking the button does not jump to the specified URL.

<div class="test-ft">

<form needcheck="1" method="post" target="_blank" action="http://www.go108.com.cn/go108_mobile_free_sz.php">

<button class="btn-act">Test now</button>

</div>

Definition and Usage The type attribute specifies the type of button. Tip: Always specify a type attribute for buttons. The default type for Internet Explorer is "button", while the default in other browsers (including the W3C specification) is "submit". It can be seen that in other browsers, the form will be submitted after the button is clicked by default, while in IE, the form is not submitted after clicking by default. The default value of type is also a browser compatibility issue, so mark it.
