我怎样才能请求一定数量的(数字)在一定的时间被插入一个输入元素? [英] How could I request a certain number (digit) with a certain times to be inserted in an input element?
问题描述
我需要从某个用户输入一个确定的数字来插入一个输入元素数字,让我们说数字9,在文本或密码字段中,以任何格式..
我怎么能使用HTML5或任何其他方式?
如果我有这样的代码:
< td><输入类型=9仅限数字placeholder =仅限数字9value =<?php echo htmlentities($ password);?passwordname =passwordmaxlength =9pattern =\d +title = >中/>< / TD>
然后,我需要的模式为例:(x是任何数字)
$ b 或者:
x9x9x9xxx
或:
9xxx9xxx9
或:
x9xxxx99x
这个问题是每次插入数字9的3倍。
正则表达式使用此工具: http://gskinner.com/RegExr/ 。
这个模式应该可以工作: [^ 9。] * 9 [^ 9。] * 9 [^ 9。] * 9 [^ 9。] *
How could I request a certain digit with a certain times to be inserted in an input element?
I need to request from The users to input three times a certain digit, let we say number 9, in the text or password field, in any format..
How could I do that using HTML5 or any other way?
If I had this code:
<td><input type="password" name="password" maxlength="9" pattern="\d+" title="9 numbers only" placeholder="9 numbers only" value="<?php echo htmlentities($password); ?>" /></td>
Then, my required pattern to be as example: ("x" is any digit)
xxx999xxx
Or: x9x9x9xxx
Or: 9xxx9xxx9
Or: x9xxxx99x
It doesn't matter the format, the matter is 3 times of number 9 to be inserted every time.
You can use this tool for Regular Expressions: http://gskinner.com/RegExr/.
This pattern should work: [^9.]*9[^9.]*9[^9.]*9[^9.]*
