jQuery に基づく div スライダーがあります。魅力的に機能します。
唯一の問題は、2 回クリックすると div の位置が台無しになる可能性が高く、前のボタンがアクティブなまま空の領域になる可能性があることです。
スライド/フェード中、およびdivが配置されるまでクリックを無効にするにはどうすればよいですか?
-以下のコードを参照してください。

text-decoration:none; }
a:hover {
font-weight:bold; }

var SlideSpeed = 500;
$(document).ready(function() {
// set the prev and next buttons display
SetNavigationDisplay();
});
function CurrentMargin() {
// get current margin of slider
var currentMargin = $("#h_wrapper").css("margin-left");
// first page load, margin will be auto, we need to change this to 0
if (currentMargin == "auto") {

// if current margin is at 0, then we are at the beginning, hide previous
if (currentMargin == 0) {

}
// get wrapper width
var wrapperWidth = $("#h_wrapper").width();
// turn current margin into postive number and calculate if we are at last slide, if so, hide next button
if ((currentMargin * -1) == (wrapperWidth - SlideWidth)) {
