html5 required validator not working with input type=button
提问by iJade
Here is my html code
这是我的 html 代码
<form id="form1" runat="server">
<input id="q" required />
<input id="btn" type="submit" value="Search">
</form>
I have used html5 required field validators, it works but with a post back. so modified the code as follows to avoid postback
我已经使用了 html5 必需的字段验证器，它可以工作但带有回发。所以修改代码如下以避免回发
<form id="form1" runat="server">
<input id="q" required />
<input id="btn" type="button" value="Search">
</form>
But the required validator doesn't work
但是所需的验证器不起作用
回答by Max
That's because the required validator is only called on submit, and the type=button is not a submit. Try this (http://jsfiddle.net/upgradellc/vrTLw/):
这是因为所需的验证器仅在提交时调用，而 type=button 不是提交。试试这个（http://jsfiddle.net/upgradellc/vrTLw/）：
<form id="form1" runat="server">
<input id="q" required />
<input id="btn" type="submit" value="Search">
</form>
