可以使用正则表达式来比较和匹配一组单词吗？

Question

比如我想要这样的字符串...
"loan nation"

匹配这些...

"Loan Origination"

"international loans"

but not on these...

"home mortgage loan"

"Loan Application"

Answer 1

根据您的要求，我会建议使用自定义函数，例如，checkMatch(str) 接受字符串和 return 找到或未找到匹配项的布尔值。

var strToMatch = "loan nation";

var str1 = "Loan Origination";
var str2 ="international loans";
var str3 = "home mortgage loan";
var str4 = "Loan Application";

function checkMatch(str){
  var strToMatchArray = strToMatch.split(' ');
  var matched = true;
  for(var i=0; i<strToMatchArray.length; i++){
    if(str.toLowerCase().indexOf(strToMatchArray[i].toLowerCase()) === -1){
      matched = false;
      break;
    }
  }
  return matched;
}
//match
console.log(checkMatch(str1));
console.log(checkMatch(str2));
//do not match
console.log(checkMatch(str3));
console.log(checkMatch(str4));
