但是不能满足我的需求,在安卓下正常,但是在iPhone下就不行了。比如如果是卡号的话,按照这里所说,应该用type=”number”,但是我们卡号是0打头,这种情况下会输入框失去焦点时,自动删除开头的0。后来谷歌到一个外国网站有讲。http://sja.co.uk/2012/1/4/controlling-which-ios-keyboard-is-shown
Controlling which iOS keyboard is shown →
Note: This is a minor update to a post I made last year, migrated from a previous blog.
One of my pet hates (there are many), is being presented with the incorrect keyboard, or having auto capitalisation forced upon me, when entering information into web forms on my iPhone or iPad. This is something that’s very easy to control and can be done so with a little sprinkle of HTML5. You don’t even have to worry about old browsers – I’ve tested this to work perfectly well even in IE6.
The screenshots used in this post are from a UK based iPhone 4S running iOS5; previous versions of iPhone OS and the iPad will differ.
Text keyboard
Your standard text input field code will look something like this:
<input type="text"></input>
Telephone keyboard
In order to display the telephone keyboard, use this:
<input type="tel"></input>
URL keyboard
For URLs you want this:
<input type="url"></input>
Email keyboard
For email addresses, you want this:
<input type="email"></input>
Numerical keyboard
And finally, for a simple numerical keyboard (similar to the telephone one but with no +, * and # key):
<input type="text" pattern="[0-9]*"></input>
Other options
It’s also possible to control auto correct with the use of the following paramater:
autocorrect="off"
Last, but by no means least, turning on or off auto capitalisation:
autocapitalize="off"
So the next time you’re creating a login field that takes an email address, use something like this:
<input type="email" autocorrect="off" autocapitalize="off"></input>
至于在安卓和苹果上的区分,可以采用php来判断用户当前的操作系统,然后分别给出不一样的输入框,函数如下:
//判断用户的客户端类型
function clientType(){
if(stristr($_SERVER[‘HTTP_USER_AGENT‘],’Android’)) {
return “android”;
}else if(stristr($_SERVER[‘HTTP_USER_AGENT‘],’iPhone’)){
return “ios”;
}else{
return “other”;
}
}
