jquery - 如何创建一个简单的 setTimeout 循环

Question

我只需要通过一个元素的 3 个变体创建一个无限循环。这是我到目前为止所拥有的:

    var count = 1;
    setTimeout(transition, 2000);

    function transition() {

        if(count == 1) {
            $('#ele').html('variation 2');
            var count = 2;

        } else if(count == 2) {
            $('#ele').html('variation 3');
            var count = 3;

        } else if(count == 3) {
            $('#ele').html('variation 1');
            var count = 1;
        }

        setTimeout(transition, 2000);

    }

尝试一下:

var count = 1;

function transition() {

    if(count == 1) {
        $('#ele').html('variation 2');
         count = 2;

    } else if(count == 2) {
        $('#ele').html('variation 3');
         count = 3;

    } else if(count == 3) {
        $('#ele').html('variation 1');
        count = 1;
    }

}
setInterval(transition, 2000);
