javascript - 当我在输入中询问时，如何让 Javascript 显示当前时间？

Question

我想查看在输入中输入某些特定文本时的当前时间，但它不起作用

HTML

        <form>
            <input type="text" id="inputcommand"></input>
            <input type="button" value="Submit" onclick="showTime()"></input>
        </form>
            <p id="output">Output here</p>

Javascript

var command = document.getElementById("inputcommand");
var output = document.getElementById("output");
var showTime = function(){
var askForTime = ["What time is it?","Show me time","Time"];
if(command.value === askForTime){
    output.innerHTML = Date();
}
};

Answer 1

使用for循环迭代数组值askForTime

var command = document.getElementById("inputcommand");
var output = document.getElementById("output");
var showTime = function(){
var askForTime = ["What time is it?","Show me time","Time"];

for(var i=0; i<askForTime.length; i++)
if(command.value == askForTime[i]){
    output.innerHTML = Date();
}
};
