jQuery 自动改变 div

Question

我编写了一个简单的代码来更改 divs... 但我认为如果它自动切换超时会很好。

A 创造了一切，唯一的问题是我不是 js 程序员。

如果可能的话，HTML A 想保持现在的状态。我只会更改 js。 我认为 js 代码不是很好，但不知何故必须开始:)

Answer 1

在完全不改变你的 html 的情况下，这就是我所拥有的:

// link the btns and the descriptions
$('.btn1').data('description', '.clean-description');
$('.btn2').data('description', '.doc-description');
$('.btn3').data('description', '.app-description');
$('.btn4').data('description', '.web-description');

// for each div in the .features section (btns) add a click event
$(".features div").on("click", function (e) {
    e.preventDefault();
    $('.features div').removeClass('selected');
    $(this).addClass('selected');
    $('.green-section .text-inner p').hide();
    $($(this).data('description')).show();
});

// Add a function to click the next btn in the .features section
function clickNext() {
    var divs = $('.features div.selected').next();
    if (divs.length) {
        divs[0].click();
    } else {
        $('.features div')[0].click();
    }
}

// add an interval to click the next btn every 4 seconds
setInterval(function () {
    clickNext();
}, 4000);

但是，我建议在 html 中添加数据标签，并确保绿色部分和功能部分具有 ID。这将确保您使用 jquery 代码定位正确的对象。
