formvalidtor在thinkphp中的正则表达式书写的问题??大家帮忙

Jun 23, 2016 pm 02:02 PM


使用formValidator-4.1.3.js进行email格式check。
书写方式如下。

   $("#email").formValidator({onShow:"请输入邮箱",onFocus:"邮箱6-100个字符,输入正确了才能离开焦点",onCorrect:"恭喜你,你输对了",defaultValue:"@"}).inputValidator({min:6,max:100,onError:"你输入的邮箱长度非法,请确认"}).regexValidator({regExp:"^([ \\w-.]+)@(([[0-9]{1,3}.[0-9]{1,3}.[0-9]{1,3}.)|(([\\w-]+.)+))([a-zA-Z]{2,4}|[0-9]{1,3})(]?)$",onError:"你输入的邮箱格式不正确"});


在静态网页中测试正常。但是在thinkphp的模板文件中,经过解析后的代码变成了
regExp:"^([ \w-.]+)@(([[0-9]{1,3}.[0-9]{1,3}.[0-9]{1,3}.)|(([\\w-]+.)+))([a-zA-Z]{2,4}|[0-9]{1,3})(]?)$"

导致formValidator报字“符集越界”的问题。

为什么表达式被更改了。\\w变成了\w?
请大家帮忙确认!

模板文件会被读取到变量中,所以 \\w 变成了 \w
要写作 \\\w 或 \\\\w

谢谢回复。按照上述修改后ok了。
还有一点疑问。

regExp:"^([ \\w-.]+)@(([[0-9]{1,3}.[0-9]{1,3}.[0-9]{1,3}.)|(([ \\w-]+.)+))([a-zA-Z]{2,4}|[0-9]{1,3})(]?)$"

表达式中有两个 \\w,为什么只有前面前面的 \\w被转换成了 \w,后面的\\w可以不变的?

这就不清楚了,需要看 php 的 C 源代码才能分析原因
不过这不是什么人都可以做到的
实际使用中也不必深究,遇到加一个“\”不行时就再加一个,如此循环知道不出错

你可以看到国外的不少代码中会有连续四五个 \ 的

可能thinkphp在模板解析时,只对字符串中的第一个\\进行变换,后面的都当作字符串处理了。
谢谢了。
