我有一个返回如下结果的函数：given output
我的给定字符串可以与此示例进行比较：
var string ='111 1 1 \ n 1111111 1 \ n 11111 11 11'
好的，你看：我的字符串中包含一些'1'，空格和新行字符。
现在我想得到像这样的正则表达式结果（删除所有带红色圆圈的字符）：result output
正则表达式应删除所有'1'字符 未连接 big '1'字符行。
（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'1'/'' - 未直接连接到2个空格字符之间的最大字符串的组 - ['1111111111111111']）
我希望你能明白我的意思:)。
提前致谢，乔纳森

我认为，其中一种方法是使用\ b
' 111 1 '.replace(/(\b1{0,7}\b)|( +)/gi, '')
答案 1 :(得分：0)
您可以尝试像\d{8,}这样简单的事情。此正则表达式将帮助您将任何数字\d与其8位或更多数字的条件进行匹配。
演示：https://regex101.com/r/bvhMDL/1/
实施例
var string = ' 111 1111111111111111 11 1';
var regex = /\d{8,}/g;
var match = regex.exec(string);
document.write(match[0])
如果你的字符串有多行，这是另一个例子。
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);
}
使用实际数据时，请确保使用1{8,}而不是\d{8,}，因为您在那里输入了零。这是一个有实际日期的例子
