正则表达式：如何删除未连接到图形的所有字符（特定字符旁边）

Question

我有一个函数返回这样的结果： 给定输出

我给定的字符串可以与以下示例进行比较：

var string ='111 1 1 \\ n 1111111 1 \\ n 11111 11 11'

好的，您看到了：我的字符串包括一些'1' ， 空格和换行符 。

现在，我想获得像这样的正则表达式结果（ 删除所有红色圆圈的字符 ）： 结果输出

所以，正则表达式应该删除 1,1'-字符列所有“ 未连接到大 1,1'- 人物 。

（对不起，我知道这听起来很疯狂，但我确实需要这个结果：p）

例：
var string=' 111 1111111111111111 11 1'

var result='1111111111111111' 

（删除所有不直接连接到两个空格字符之间的最大字符串的组'1'/'' -['1111111111111111']）

我只是希望你能明白我的意思：）

预先感谢，乔纳森

Answer 1

我认为，方法之一是使用\\ b

 '    111   1  '.replace(/(\b1{0,7}\b)|( +)/gi, '')

Answer 2

您可以尝试使用\\d{8,}这样简单的方法。 此正则表达式将帮助您匹配具有8位或更多数字的任何\\d数字。

演示： https ： //regex101.com/r/bvhMDL/1/

例

 var string = ' 111 1111111111111111 11 1'; var regex = /\\d{8,}/g; var match = regex.exec(string); document.write(match[0]) 

如果您的字符串有多行，这是另一个示例。

 var string = ` 111 1 1111111111111111 11 1 11 1 1\\n 11111111111 11 1 1 1\\n 1 1111111111111111111 11 1 11 1\\n 111111111111 11 1 111 1111111111111111111 11 1 1 1 1\\n 1111111111111111 11 1 111 1111111111111111111 11 1 11 \\n 111111111111 11 1 `; var regex = /\\d{8,}/g; var match = regex.exec(string); while (match != null) { document.write(match[0]+'<br>') match = regex.exec(string); } 

对于真实数据，请确保使用1{8,}而不是\\d{8,}因为那里有零作为输入。 这是真实日期的示例
