所以我正在做我的学校项目，我试图显示与电话相同的错误“不匹配”，但我不知道我做错了什么。我附上了输出的屏幕截图。
最佳答案
正确输入密码后，您没有重置 #status 文本。试试这个:
if (pass1 != "" && pass2 != "") {
if (pass1 != pass2) {
document.getElementById("status").innerHTML = "<span>X</span> Doesn't Match.";
} else document.getElementById("status").textContent = 'ok';
}
对于电话部分，您有一个或两个拼写错误:"showEorror" 与 "showEorrr"，这再次意味着错误文本不会消失.我建议改用 showError 或 showPhoneError。
