javascript - 将变量传递给 setTimeout()

Question

我想这样做:

var whatever = myfunction;
var time = 200;
setTimeout(whatever, time);

function myfunction() {
    //do something
}

它不起作用，我不确定为什么

更好的例子:这是html网页:

<div id="example1" class="example-card" style="visibility: hidden;"></div>
<div id="example2" class="example-card" style="visibility: hidden;"></div>

这里是JSJS:

function example1() {
    $("#example1").css('visibility', 'visible');
}
function example2() {
    $("#example2").css('visibility', 'visible');
}

$(window).on("load", function(){
    var time = 0;
    $('.example-card').each(function() {
        var exampleId = this.id;
        setTimeout(exampleId, time);
        time = time + 200;
    });
});

谢谢

    alert("hi");
}
