PHP正则表达式和JavaScript正则表达式之间的区别 [英] Difference between PHP regex and JavaScript regex

问题描述

您好我想在spry java脚本框架中使用下面的php正则表达式，但它们不能用于spry框架，spry不会让用户输入！。$
1）/ ^ [\d] + $ /

2）/ ^（[\ x {600} -\ x {6FF}] + \ s）* [\ x {600} -\ x {6FF}] + $ / u

3）/ ^（[{\x 600} {-\x} 6FF] + \d * \s）* [{\x 600} {-\x} 6FF] + \ d * $ / u

请帮我转换它们在spry框架中使用。

Hi i want to use below php regex in spry java script framework but them doesn't work with spry framework and spry doesn't let the user to input!.
1)"/^[\d]+$/"
2)"/^([\x{600}-\x{6FF}]+\s)*[\x{600}-\x{6FF}]+$/u"
3)"/^([\x{600}-\x{6FF}]+\d*\s)*[\x{600}-\x{6FF}]+\d*$/u"
please help me to convert them to use in spry framework.

推荐答案

1) /^[\d]+$/
2) /^([\u0600-\u06FF]+\s)*[\u0600-\u06FF]+$/
3) /^([\u0600-\u06FF]+\d*\s)*[\u0600-\u06FF]+\d*$/

/ u不受支持，因为Javascript正则表达式仅支持unicode代码点条款。 \ x {???}（unicode codepoints）应写成\u ????在Javascript正则表达式中（总是4位0填充）

/u is not supported, since Javascript regexes only supports unicode in terms of codepoints. \x{???} (unicode codepoints) should be written \u???? in Javascript regex (always 4 digits 0 padded)

在这些情况下，以下内容适用于正则表达式的其余部分：

In these cases, the following applies to the rest of the regex:

• \s在Javascript中被视为unicode


• \d不是，这意味着只接受ASCII数字（0-9） 。

这意味着我们必须特别允许外国数字，例如波斯语（代码点06F0-06F9）：

This means we specifically have to allow "foreign" numerals, e.g. Persian (codepoints 06F0-06F9):

1) /^[\d\u06F0-\u06F9]+$/
2) /^([\u0600-\u06FF]+\s)*[\u0600-\u06FF]+$/
3) /^([\u0600-\u06FF]+[\d\u06F0-\u06F9]*\s)*[\u0600-\u06FF]+[\d\u06F0-\u06F9]*$/

（如果不接受ASCII数字，则删除\d）

(Remove \d if ASCII digits shouldn't be accepted)

不确定括号在示例1中应该做什么，最初可以写成：

Not sure what the brackets are supposed to be doing in example 1, originally they could be written:

1) /^\d+$/

但要添加波斯数字，我们需要它们，见上文。

But to add the Persian numerals, we need them, see above.

更新

然而，Spry字符屏蔽只需要一个正则表达式应用于每个输入的字符 - 即，我们实际上不能进行模式匹配，它只是所有位置中接受字符的列表，在这种情况下：

Spry character masking, however, only wants a regex to be applied on each entered character - i.e., we can't actually do pattern matching, it's just a "list" of accepted characters in all places, in which case:

1      ) /[\u06F0-\u06F9\d]/      // match 0-9 and Persian numerals
2 and 3) /[\u0600-\u06FF\d\s]/    // match all Persian characters (includes numerals), 0-9 and space

如果您不想接受，请再次删除\d 0-9。

Once again, remove \d if you don't want to accept 0-9.

更新2

现在...使用正则表达式使用Spry 验证：

Now... using regex for validation with Spry:

var checkFullName = function(value, options)
{
   // Match with the by now well-known regex:
   if (value.match(/^([\u0600-\u06FF]+\s)*[\u0600-\u06FF]+$/))
   {
      return true;
   }
   return false;
}

var sprytextfield =
     new Spry.Widget.ValidationTextField(
          "sprytextfield", 
          "custom", 
          { validation: checkFullName, validateOn: ["blur", "change"] }
     );

可以为案例3制作类似的自定义函数。

A similar custom function can be made for case 3.
