javascript - 根据多个值显示隐藏 div

Question

我正在尝试将 this.value 与多个选项进行比较，我该怎么做？我无法弄清楚将 this.value 与更多选项进行比较的语法...

window.onload = function(){
    var elem = document.getElementById("country-list");
    elem.onchange = function(){
        var hiddenDiv = document.getElementById("showMe");
        hiddenDiv.style.display = (this.value != "option1","option2") ? "none" : "block";
    };    
}

Answer 1

您需要为此添加一个“and”运算符。

hiddenDiv.style.display = (this.value != "option1" && this.value != "option2") ? "none":"block";
