道客网站建设推广小程序,在邯郸开互联网公司,wordpress怎么禁止评论,建设一个网站需要哪方面的费用先上效果图#xff0c;图片顺序可移动#xff0c;左移右移调准顺序。 代码是文心一言帮忙写的#xff0c;自己稍微改造就可以用了。 首先是往左移#xff0c;也就是从下标1移到下标0 #xff0c;下标2移到下标1 var imglist [‘aa’, ‘bb’, ‘cc’, ‘dd’];
function… 先上效果图图片顺序可移动左移右移调准顺序。 代码是文心一言帮忙写的自己稍微改造就可以用了。 首先是往左移也就是从下标1移到下标0 下标2移到下标1 var imglist [‘aa’, ‘bb’, ‘cc’, ‘dd’];
function moveElementBefore(currentElement, targetElement) { var currentIndex imglist.indexOf(currentElement); var targetIndex imglist.indexOf(targetElement);
if (currentIndex 0 || targetIndex 0 || currentIndex targetIndex) { return; // currentElement not found or targetElement not found or currentElement and targetElement are the same }
imglist.splice(currentIndex, 1); // remove currentElement from the list imglist.splice(targetIndex currentIndex ? targetIndex : targetIndex - 1, 0, currentElement); // insert currentElement before targetElement }
其次是右移下标0移到1下标3移到下标4 var imglist [‘aa’, ‘bb’, ‘cc’, ‘dd’, ‘ee’, ‘ff’];
function moveElement(element, targetElement) { var elementIndex imglist.indexOf(element); var targetIndex imglist.indexOf(targetElement);
// 检查元素是否在数组中以及目标元素是否存在 if (elementIndex 0 || targetIndex 0 || element targetElement) { return; }
// 移动元素 imglist.splice(elementIndex, 1); imglist.splice(targetIndex elementIndex ? targetIndex 1 : targetIndex, 0, element); }
