我在html下方的轮播中有一些图片。我想通过jQuery更改轮播的图像。
当我在控制台中使用单个命令时，图像会发生变化。但是，如果我在javascript中使用相同的命令，则图像不会更改。

jQuery 1st：
$("#slick-slide02").find(">div > .ig-hp-carousel-item > .ig-carousel-image img").attr("src","https://www.xxx.in/content/dam/xxx/yyy-website/banner/2018/10/PHK-to-delhi_HOMEPAGE.jpg");
JavaScript：
<script>
function homepageBannerLoad()
{
$("#slick-slide02").find(">div > .ig-hp-carousel-item > .ig-carousel-image img").attr("src","https://www.xxx.in/content/dam/xxx/yyy-website/banner/2018/10/PHK-to-delhi_HOMEPAGE.jpg"); //jQuery 1st
console.log("first banner changed");
$("#slick-slide00").find(" > div > .zz-hp-carousel-item > .zz-carousel-image > .container.carousel-container.zz-container > .zz-carousel-item-text > .carousel-text-wrapper > div >h1").text("Banner A");
$("#slick-slide00").find(" > div > .zz-hp-carousel-item > .zz-carousel-image > .container.carousel-container.zz-container > .zz-carousel-item-text > .carousel-text-wrapper > div >p:first").text("Experience the Magic of Adobe Target");
$("#slick-slide00").find(" > div > .zz-hp-carousel-item > .zz-carousel-image > .container.carousel-container.zz-container > .zz-carousel-item-text > .carousel-text-wrapper > div >h2").text("");
$("#slick-slide00").find(" > div > .zz-hp-carousel-item > .zz-carousel-image > .container.carousel-container.zz-container > .zz-carousel-item-text > .carousel-text-wrapper > .zz-carousel-action > a:first > button").html("Know More");
$("#slick-slide00").find(" > div > .zz-hp-carousel-item > .zz-carousel-image > .container.carousel-container.zz-container > .zz-carousel-item-text > .carousel-text-wrapper > .zz-carousel-action > a:last > button").remove();
$("#slick-slide00").find("> div > .zz-hp-carousel-item > .zz-carousel-image > .container.carousel-container.zz-container > .zz-carousel-item-text > .carousel-text-wrapper > div:last > a:first").attr("href","https://www.ppxxx.in");
console.log("second banner change done");
$("#slick-slide01").find(" > div > .zz-hp-carousel-item > .zz-carousel-image > .container.carousel-container.zz-container > .zz-carousel-item-text > .carousel-text-wrapper > div >h1").text("Banner B");
$("#slick-slide01").find(" > div > .zz-hp-carousel-item > .zz-carousel-image > .container.carousel-container.zz-container > .zz-carousel-item-text > .carousel-text-wrapper > div >p:first").text("How Did you find it?");
$("#slick-slide01").find(" > div > .zz-hp-carousel-item > .zz-carousel-image > .container.carousel-container.zz-container > .zz-carousel-item-text > .carousel-text-wrapper > div >h2").text("");
console.log("third banner change done");
};
window.onload = function(){homepageBannerLoad();};
</script>
因此jQuery 1st不起作用，但所有其他jQuery命令均起作用。因此想检查是否需要通过其他方式更改轮播图片。
