提交事件监听器的问题

Question

我试图使我的第一个提交事件侦听器，以便按钮响应单击事件和回车键事件。目前，它对任何一个都不响应，我不确定为什么。我没有将任何信息发送到另一个页面-我只希望它触发其他事件。

var domStrings = {
    submit: document.querySelector('#submit')
}
var checker = function() {
    var lcase;
    domStrings.submit.addEventListener("click", function(e) {
        e.preventDefault();
        console.log('form submitted');
        lCase = guess.value.toLowerCase();
        turnCounter++;
        if (entryField.value.includes(lCase)) {
            for (i = 0; i < entryField.value.length; i++) {
                if (lCase === entryField.value[i]) {
                    retainAndReplace(domStrings.word.textContent, i, lCase)
                }
            }
        } else {
            //tell user they're wrong
            wrong.style.visibility = 'visible';
            wrong.classList.add('.fade-out-wrong')
            setTimeout(invisibleWrong, 4000);
            guessCounter--;
            if (guessCounter < 1) {
                //display game over
                over.style.display = 'inline'
                chances.textContent = `Guesses remaining: 0`;
                wrong.style.display = 'none';
                //hide dashes
                word.style.display = 'none'
            } else {
                chances.textContent = `Guesses remaining: ${guessCounter}`;
            }
        }
    })
}
checker()

<input type = 'text' id = 'guess' placeholder = 'Letter Guess' maxlength = '1'>
<button type = 'submit' id ='submit'> Submit </button>
