Javascript if statement in For Loop

Question

Hi I'm following a tutorial on JS For Loop and trying something which I can't make it to work. I'm not sure what i'm missing to display the alert after checking the array in the loop. Please help me to figure out this very simple syntax issue. Thank you!

HTML

<input type= "text" id="city2check"></input>
<button type="submit" onClick="myCity()">Check</button>

JS

function myCity() {
    var cleanestCities = ["Cheyenne", "Santa Fe", "Tucson", "Great Falls", "Honolulu"];     
        for (var i = 0; i < cleanestCities.length; i++) {
            if (city2check === cleanestCities[i]) {
                alert("correct");
            }
    }
}

Answer 1

city2check refers to your input element. You want city2check.value to get its value.

Additionally:

• </input> isn't a thing. Remove it.
• Prefer document.getElementById('city2check') rather than just city2check to prevent ambiguity.

Answer 2

变量city2check包含任何值，因此比较始终为false。
