Question

我制作了一个简单的代码来更改 divs 但是我认为如果它在某些超时时自动切换会很好。

A创造了一切只有问题是我不是js程序员。

如果有可能，HTML A想要像现在一样保留..我只会改变js。我认为js代码不是很好，但必须以某种方式开始:)

对不起我的英文...并感谢任何帮助人员：）

Answer 1

根本没有改变你的html，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有id。这将确保您使用jquery代码定位正确的内容。

Answer 2

您必须在javascript中添加一个间隔，以便它可以循环遍历它们。您可能还想改变您做颜色的方式。尝试为它们添加类更简洁，更容易控制

var selectedDiv = 1;
$(document).ready(function(){
    setInterval(rotate,5000);
});


function rotate(){
console.log("ASDFASFD");
switch(selectedDiv)
{
    case 1:
      $(".btn2").click();
      break;
    case 2:
      $(".btn3").click();
      break;
    case 3:
      $(".btn4").click();
      break;
    case 4:
      $(".btn1").click();
      break;
}
}

Answer 3

在js

的末尾添加

autoToggle = function (no)
{
    $(".btn"+no).click();
    if(no == 4)
    {
       no=1; 
    }
    else
    {
         no++;   
    }
    setTimeout("autoToggle("+no+")",2000);
}
autoToggle(1);

jQuery自动更改div
