输入字段的模式属性的值，如单词“Kim”，“Kim Sun”，“Kim 2”等(Value for Pattern Attribute for Input Field like words “Kim”

输入字段的模式属性的值，如单词“Kim”，“Kim Sun”，“Kim 2”等(Value for Pattern Attribute for Input Field like words “Kim”, “Kim Sun”, “Kim 2” etc)

单词以最少3个字母开头，然后可以是空格和数字，例如“Kim”，“Kim Sun”，“Kim 2”等。在这种情况下，html输入字段的pattern属性应该是什么值？

我有一个工作正则表达式的php用于相同的目的"/^[a-zA-Z]{3,}[a-zA-Z0-9 ]+$/i" 。 我试着这样做：

<input class="form-control" type="text" name="name" id="name" value="<?php echo $name;?>" title="Must type a name starting with letters, but then numbers and white space allowed" required="required" aria-required="true" pattern="[a-zA-Z]{3,}[a-zA-Z0-9 ]" spellcheck="false" size="15">

但是pattern属性不起作用。

Words start with minimum 3 letters and then may be a white space and numbers, say "Kim", "Kim Sun", "Kim 2" etc. In this case, what should be the value for pattern attribute for html input field?

I have a working regex for php for the same purpose "/^[a-zA-Z]{3,}[a-zA-Z0-9 ]+$/i". I tried from this as :

<input class="form-control" type="text" name="name" id="name" value="<?php echo $name;?>" title="Must type a name starting with letters, but then numbers and white space allowed" required="required" aria-required="true" pattern="[a-zA-Z]{3,}[a-zA-Z0-9 ]" spellcheck="false" size="15">

But the pattern attribute is not working.

我怀疑问题是你忘了最后的+ 。

尝试： [a-zA-Z]{3,}[a-zA-Z0-9 ]+

I suspect the problem is you forgot the + at the end.

Try: [a-zA-Z]{3,}[a-zA-Z0-9 ]+
