在onClick方法中调用JavaScript函数

Question

I have this function

    function setLang(ln){
    if(ln == "en"){
        window.location = "../../en/page/login.html";
    }else if(ln == "de"){
        window.location = "../../de/page/login.html";
    }else if(ln == "fr"){
        window.location = "../../fr/page/login.html";
    }
}

and call it inline like this

<img src="../../en/EN.png" class="flag" onclick="setLang('en')">

So this is where I want to access it from, from a onclick function.

I'm quite new to JS, So that's why I'm asking how can I do that.

Answer 1

<img src="../../en/EN.png" class="flag" onclick="setLang('en')"/>
<script>
function setLang(ln){
if(ln == "en"){
    window.location = "../../en/page/login.html";
}else if(ln == "de"){
    window.location = "../../de/page/login.html";
}else if(ln == "fr"){
    window.location = "../../fr/page/login.html";
}
}
</script>
