::更新代码::
我从数组动态生成了按钮。单击按钮时,10 张静态 gif 图像会通过 API 调用附加到页面。当单击动态生成的静态图像之一时,我需要显示动画 gif。再次单击后,我需要显示静态图像并隐藏动画 gif。
lastClick = [];
var killersGifs = {
killerSearches: ["Freddy Krueger", "Jason Voorhees", "Pennywise", "Ghostface", "American Mary", "Chucky", "Bride of Chucky", "The Candyman", "Cujo", "Hannibal", "Leatherface", "Michael Myers", "Norman Bates", "Pinhead"],
buttonLoop: function() {
for (var b = 0; b < killersGifs.killerSearches.length - 1; b++) {
var buttonM = $("<button class='dynGen'>").text(killersGifs.killerSearches[b]).attr("data-index", killersGifs.killerSearches[b]);
$("#buttons").append(buttonM);
}
},
divLoop: function(click) {
var queryURL = "https://api.giphy.com/v1/gifs/search?api_key=B26sstJns2pZuNT5HiJpqS5FV8Su1sDd&q=" + lastClick + "&limit=10"
$.ajax({
url: queryURL,
method: "GET"
}).done(function(response) {
console.log(response.data);
for (var i = 0; i < response.data.length; i++) {
var respData = response.data[i];
var image = respData.images.fixed_height_small_still.url;
var gif = respData.images.fixed_height_small.url;
var rating = respData.rating;
var dynDiv = $("<div class='dyn-div'>");
//dynDiv.attr("data-index", i);
var killerImg = $("<img class='still-image'>");
killerImg.attr("src", image);
killerImg.attr("alt", "Serial Killer still frame of gif");
killerImg.attr("data-gif", gif);
killerImg.attr("class", "killerImg");
killerImg.attr("data-index", i);
dynDiv.append("<p> Rating: " + rating + "</p>");
dynDiv.append(killerImg);
$("#append-img-div").prepend($(dynDiv));
};
});
},
userPush: function () {
var userInput = $("input[type='text']").val().trim();
console.log(userInput);
killersGifs.killerSearches.push(userInput);
var buttonU = $("<button class='dynGen'>").text(userInput).attr("data-index", userInput);
$("#buttons").append(buttonU);
console.log(killersGifs.killerSearches);
}
};
killersGifs.buttonLoop();
$("#killer-add-submit").on("click", function(event) {
event.preventDefault();
killersGifs.userPush();
});
$(document).on("click", "button.dynGen", function(event) {
var currentIndex = $(this).attr("data-index");
lastClick.push(currentIndex);
console.log(currentIndex);
event.preventDefault();
$("#append-img-div").empty();
killersGifs.divLoop();
lastClick = [];
});
$(document).on("click", ".killerImg", function(event) {
console.log("test");
var currentIn = $(this).attr("data-index");
var tempUrl = $(this).attr("data-gif");
console.log(currentIn);
console.log(tempUrl);
});
单击时,单击的图像应在静态图像和动画 gif 之间切换。
单击功能控制台记录单击图像的索引和正确的 gif URL。我不知道如何合并它来交换点击时的 gif 和图像。
最佳答案
我认为您需要将 gif url 设置为您使用 jQuery 创建的 img 元素的属性。像这样的东西:
`killerImg.attr("data-gif", gif);`
正如您已经定义的那样
var gif = respData.images.fixed_height_small.url;
。您可能还想给它一个唯一的 ID,例如:
killerImg.attr("id", "killer-img");
然后,在单击事件中,您可以从元素本身检索该属性:
var tempUrl = $("#killer-img").attr("data-gif");
并用 img src 将其切换为:
$("#killer-img").attr("data-gif") = $("#killer-img").attr("src");
最后:
$("#killer-img").attr("src") = tempUrl
将图像源设置为移动 gif。
我最近自己处理了一个非常类似的任务。希望这有帮助!
