如果发现文本上有任何单词，我该怎么说?

Question

我正在尝试检查文本上是否包含任何单词console.log(1)或console.log(2)为 false ，但是我得到了1,2,1,2，因为它是匹配的，并且有些失败，但我希望如果只包含给定单词中的一个单词，那么ok，但如果不是假的，但我得到真， 假

}
console.log(2)
}

Answer 1

不要记录在循环中，而是使用常规变量来计算匹配项，然后检查变量。

例如：

let matches = 0;
for (var i = 0; i < keywords.length; i += 1) {
// Note that indexOf returns -1 on failure, not false or zero
if (data.indexOf(keywords[i]) !== -1) {
matches++;
}
}
if(matches) {
console.log(1);
}
else {
console.log(2);
}

Answer 2

您可以将some与includes结合使用，以检查keywords中的单词是否在data中，然后记录所需的输出：

var keywords = ['aslr', 'ida pro', 'gdb', 'windbg', 'immunity debugger', 'boofuzz', 'peach fuzzer', 'winafl', 'python', 'assembly', 'penetration testing', 'exploits', 'metasploit', 'metasploit framework', 'ethical hacker', 'pentest', 'computer security', 'hacking', 'oscp', 'osce', 'osee', 'penetration testing', 'offensive security', 'mitre att&ck', 'vulnerability research', 'vulnerability researcher', 'fuzzing', 'clang', 'llvm', 'address sanitizer', 'afl', 'fuzzers', 'penetration tester'];

if (keywords.some(word => data.includes(word))) console.log(1);
else console.log(2);

Answer 3

您可以使用变量来检查找到的关键字数量，因为您只需要一个关键字，如果 count 的值超出1则脱离循环并相应地显示值

var keywords = ['aslr', 'ida pro', 'gdb', 'windbg', 'immunity debugger', 'boofuzz', 'peach fuzzer', 'winafl', 'python', 'assembly', 'penetration testing', 'exploits', 'metasploit', 'metasploit framework', 'ethical hacker', 'pentest', 'computer security', 'hacking', 'oscp', 'osce', 'osee', 'penetration testing', 'offensive security', 'mitre att&ck', 'vulnerability research', 'vulnerability researcher', 'fuzzing', 'clang', 'llvm', 'address sanitizer', 'afl', 'fuzzers','penetration tester']

let matchCount = 0
for (var i = 0; i < keywords.length; i += 1) {
if (data.includes(keywords[i])) {
matchCount++
}
if (matchCount > 1) break
}
console.log(matchCount === 1 ? 1 : 2)
