Question

我有一个以下格式的字符串，

Hello this #result1# is a sample #result2# string with a lot of # and #result3# i need to find all the values between #

我需要基于javascript或nodejs的解决方案，只能返回['result1' , 'result2' , 'result3']。

规则：

预期结果之间没有空格
预期结果之间没有#。
应排除['result1# is a sample #result2# string with a lot of ' , 'result1# is a sample ']

Answer 1

＆＃13;

var str = 'Hello this #result1# is a sample #result2# string with a lot of # and  #result3# i need to find all the values between #';
console.log(str.match(/#[^#\s]+#/g));

＆＃13;

<强>解释

/        : regex delimiter
 #       : # character
 [^#\s]+ : 1 or more character that is NOT # or space
 #       : # character
/g       : regex delimiter and global flag

Answer 2

以下代码段应该有效：

＆＃13;

let str = "Hello this #result1# is a sample #result2# string with a lot of # and  #result3# i need to find all the values between #";
let identifier = '#';

function getSubstrings(str, identifier) {
    let results = [];
    let splittedItems = str.split(identifier);
    splittedItems.forEach(
        function(item) {
            if (item.length > 1 && item.indexOf(' ') === -1) {
                results.push(item);
            }
        }
    );
    return results;
}
document.write(getSubstrings(str, identifier));

＆＃13;

Answer 4

您的问题可能有许多特殊情况，如果没有关于您尝试过的内容以及失败的详细信息，很难给出明确的答案。您可以尝试从以下开始：

var input = 'Hello this #result1# is a sample #result2# string with a lot of # and  #result3# i need to find all the values between #';
output = input.match(/#[A-Za-z0-9]+#/g);
console.log(output); //["#result1#", "#result2#", "#result3#"]

[A-Za-z0-9]匹配任何大写字母（A-Z），小写字母（a-z）和数字（0-9）

+表示前面的模式至少应出现一次

g表示全局，因此匹配字符串

中模式的所有出现
