如何使用從 API 獲取的圖像在 div 上生成動態輪播
[英]How Generate Dynamic carousel on div with images fetch from an API
問題描述
我正在嘗試生成一個動態橫幅輪播，在其中，我想 append 通過 API 獲取的圖像。 數據進入控制台但無法 append 它。
如何 append 它在 Image 標簽內並相應地生成動態 div？

您可以通過 Id 獲取橫幅元素。 然后更新innerHTML
var el = document.getElementById("banner");
el.innerHTML="<img src=\"http://placehold.it/350x350\">";
或嘗試
var el = document.getElementById("id for banner img");
el.src="url";

在 displayCarousel function 中進行以下更改：
function displayCarousel(data){
console.log("data inside display function....", data);
for(var i=0; i<data.length;i++){
var img_url = _spPageContextInfo.webAbsoluteUrl + '' + data[i].ServerRelativeUrl;
var img_div = '<div class="mySlides fade"><img src="'+img_url+'"> </div>';
$("#slideshow-container").append(img_div);
}
}
