Question

我正在创建一个聊天机器人，我需要帮助，我在Google上搜索了很多，但没有任何帮助。

我想做这样的事情：

var input = $('#InputField').html(); //consider it as hi, how are you!

var commonGreetings = ["hi", "hello"];
var questions  = [{commonGreetings} +",how are you!"]; // i want to check if first word of sentence is in the array named commonGreetings.

//然后

var answers  = ["i am fine, thank you!"];

    if(questions.indexOf(input ) > -1){
        $('#output').html(answers[0]);
    }

Answer 1

使用不区分大小写的匹配对输入进行正则表达式
使用Array.includes（matched.toLowerCase（）

const input = "  Hello World!"

const commonGreetings = ["hi", "hello"]
const rx = /^\s*(\w+)/
const m = rx.exec(input, 'i')
if (m) {
  const found = m[1].toLowerCase()
  if (commonGreetings.includes(found)) {
    console.log(`Found a match for ${found}`)
  }
}

Answer 2

第一个解决方案：

var firstWord = input.match(/\w*/)[0];
if(commonGreetings.indexOf(firstWord) > -1){
    $('#output').html(answers[0]);
}

或者，您可以使用map方法来生成这样的问题数组：

var questions = commonGreetings.map(function(commonGreeting) {
    return commonGreeting + ', how are you!'
});

使用另一个数组中数组的值来解析句子
