我已经使用javascript成功创建了一个div,它充满了从API收集的数据。我想要获取部分数据(所有来自Episode,SeasonxEpisode等的innerHTML文本)并将其放入包含div中,以便我可以将其隔离为css样式。
这是我的代码,所有内容都在同一个父级中。还有一个图像从episodeDiv中显示的API中提取,但它不包含在此代码段中,因为它不是问题的一部分。
<script>
let savedResponse;
function clickSeason (seasonNum) {
const currentSeason = savedResponse['season'+ seasonNum];
$("#episode-list").html("");
currentSeason.forEach(function(episode){
const episodeDiv = document.createElement('div');
$(episodeDiv).addClass("episodeStyle");
episodeDiv.innerHTML =
"Episode: " + episode.title + '<br />' + '<br />' +
"SeasonxEpisode: " + episode.episode + '<br />' +
"Original Airdate: " + episode.airdate + '<br />' +
" Stardate: " + episode.stardate + '<br />' +
episode.summary;
$('#episode-list').append(episodeDiv);
</script>
您可以在此处看到完整的项目:http://idesn3535-flamingo.surge.sh/Final/index.html
完整的代码在这里:https://github.com/bmaxdesign/idesn3535-flamingo/blob/master/Final/index.html
我尝试了几个版本:
const episodeData = document.createElement('p');
$(episodeData).addClass("episodeDataStyle");
episodeData.innerHTML =
"Episode: " + episode.title + '<br />' + '<br />' +
"SeasonxEpisode: " + episode.episode + '<br />' +
"Original Airdate: " + episode.airdate + '<br />' +
" Stardate: " + episode.stardate + '<br />' +
episode.summary;
$("episodeData").appendChild(episodeDiv);
我希望父节点成为episodeDiv,然后我想将episodeData作为具有单独id的子项嵌套到css中。不幸的是,我上面的内容实际上使整个剧集甚至没有显示,我认为这意味着我的附加方式有一些错误。我想我有一些标签混淆或语法错误,或上述所有。我试图避免在我的HTML页面中留下一个空元素,但我也会对这种方法以及如何将文本放在空div中感到困惑。我显然还没有理解DOM操作。
请确保您的回复包含原因和方式,以及我可以用来更好地理解这一点的任何关键字或链接。教一个人钓鱼等等。非常感谢你!

我喜欢使用template literals和Array.map
来实现您的目标。皮肤猫的方法有很多种,但这种方法非常紧凑和可读。
// map the episode objects into strings of html
var episodeHTMLArray = currentSeason.map(episode => {
return `
<div class='episode'>
Episode: ${episode.title} <br /> <br />
SeasonxEpisode: ${episode.episode} <br />
Original Airdate: ${episode.airdate} <br />
Stardate: ${episode.stardate}<br />
${episode.summary}
</div>
`
})
// join the array of html into a plain string
$('#episode-list').html(episodeHTMLArray.join(''))
模板文字是反引号而不是引号,它们可以使用语法${varName}
在当前范围内呈现任何变量。
另外,我想我应该指出$("episodeData")
正在寻找一个看起来像<episodeData></episodeData>
的元素。小心你的选择器。

好吧,我在这里写了一些不同的代码,我喜欢手动创建DOM元素而不是编程,我更喜欢jQuery语法 - 而且当你使用jquery时,它应该不是问题:
function clickSeason (seasonNum) {
const currentSeason = savedResponse['season'+ seasonNum];
/*empty (remove everything from) the epsiode list div*/
$("#episode-list").empty();
/*declare empty !string! variable for loop, where we can store all the
generated divs - this div has to be declared above the FOR loop,
as we dont want to overwrite it each loop,
we want to add something to it each loop*/
var ep = "";
/*loop through current season array/JSON*/
for(var i = 0; i<currentSeason.epsiode.length; i++){
/*every loop, we add this structure to ep variable*/
/*generate div id by variables, in this example, the id will be for
first season second episode like ep1-2*/
ep+= "<div id='ep"+seasonNum+"-"i+"' class='episodeStyle'>";
ep+= "Episode: " + currentSeason.episode[i].title + "<br /><br />";
ep+= "SeasonxEpisode: " + currentSeason.episode[i].episode + "<br />";
ep+= "Original Airdate: " + currentSeason.episode[i].airdate + "<br />";
ep+= " Stardate: " + currentSeason.episode[i].stardate + "<br />";
ep+= currentSeason.episode[i].summary;
ep+= "</div>";
}
/*loop ended, you can now add it to any other dom element you like*/
$('#episode-list').append(ep);
}
现在有点理论:
$('#myElementID').append(something);
将(作为最后一个孩子)添加到具有该ID的确切元素。
$('.myElementCLASS').append(something);
将(作为最后一个孩子)附加到给定类的所有元素。
$('div').append(something);
将(作为最后一个孩子)添加到DOM中的所有DIV
您也可以将其与
等变量结合使用var elem="myElementID";
$("#"+elem+"1").append(something);
将附加到#myElementID1

如果我不得不使用jQuery进行模板化,我可能会做类似的事情:
currentSeason.forEach(function(episode){
let myHtml = '<div class="episodeStyle"> "Episode:" ' + episode.title + '<br />' + '<br />' + '"SeasonxEpisode: "' + episode.episode + '<br />' + '"Original Airdate: "' + episode.airdate + '<br />' + '" Stardate: "' + episode.stardate + '<br />' + episode.summary + '</div>';
myHtml.appendTo($('#episode-list'));
});

在下面的代码中,我将展示一种实际可行的方式。希望它有所帮助,因为它与oyu想要完成的东西相比是非常准确的
$(document).ready(function() {
function clickSeason() {
/*Lets say this is the data you received form your API*/
let season1 = [{
title: 'Episode 1',
episode: 1
}, {
title: 'Episode 2',
episode: 2
}, {
title: 'Episode 3',
episode: 3
}];
let seasonSelector = $("#season");
//This will Help you select the place where you
//are going to load your episodes
let divHolder;
let mainContent;
//We iterate through each element in our object array
season1.forEach(function(episode) {
//With jquery you can create a div like this.
//You also get the jQuery object for that new div.
//With this object you can manipulate your new div even further
divHolder = $("<div class='episode'></div>");
//You can append data directrly to the div
divHolder.append("<h4>" + episode.title + "</h4>");
divHolder.append("<h5>Episode:" + episode.episode + "</h5>");
//You could create new containers and still be able to manipulate the.
mainContent = $("<p class='Content'></p>");
//It could be less performant, but I prefer
//appending in sections instead of all in strings.
mainContent.append("Original Airdate: " + episode.airdate + '<br /><br />');
mainContent.append("Stardate: " + episode.stardate + '<br /><br />');
mainContent.append(episode.summary);
//We append our mainContent div to the divholder
divHolder.append(mainContent);
//We append our divHolder to the Season
seasonSelector.append(divHolder);
});
}
clickSeason();
});
