【问题描述】：
所以，我正在开发一个具有搜索功能的网页，用户可以在其中输入事件名称和朋友的姓名，页面将根据这些输入显示搜索结果。
提前道歉，我的代码绝对是一团糟（但它有效，这就是我现在关心的全部）但是，我的问题是，我不知道打印出所有搜索结果的好方法。我在网上查了一下，我现在有以下内容：
$('#searchFeedback').empty();
$.each(data.events[i], function (index, value) {
$('#searchFeedback').append(output);
})
这是我找到的最好的选择（也是唯一一个以任何方式工作的选项，即使我必须混合使用 JQuery），但问题是它重复打印出最后一个搜索结果，甚至没有正确的数量，而不是打印出每个搜索结果。我对 JQuery 完全一无所知。
这是我的整个 JS 代码：
<script>
function eventSearch() {
var eName = document.getElementById("ename").value;
var fName = document.getElementById("fname").value;
var searchResults = "";
var friendResults = "";
var attendeeText = "";
if (eName === "" && fName === "") {
document.getElementById("searchFeedback").innerHTML = "<h4 class='eName'>Fields cannot be empty!</h4>";
} else {
for (var i = 0; i < data.events.length; i++) {
searchResults = data.events[i].eName.toUpperCase();
var output = "<h4 class='eName'>" + data.events[i].eName + " • " + data.events[i].date + "</h4> <p class='eDesc'>" + data.events[i].description + "<br><sub>" + attendeeText + "<a class='event' onclick='openEventLink(" + i + ");' href=''><b> Check it out here.</b> </a></sub></p><br>";
if (eName != "" && searchResults.includes(eName.toUpperCase())) {
if (data.events[i].attendees.length != 1) {
for (var a = 0; a < data.events[i].attendees.length; a++) {
attendeeText = data.events[i].attendees.join(", ");
}
} else {
attendeeText = data.events[i].attendees;
}
if (data.events[i].attendees.length > 1) {
attendeeText = attendeeText + " are going.";
} else if (data.events[i].attendees.length == 1) {
attendeeText = attendeeText + " is going.";
} else {
attendeeText = "";
}
if (fName != "") {
for (var a = 0; a < data.events[i].attendees.length; a++) {
friendResults = data.events[i].attendees[a].toUpperCase();
if (friendResults.includes(fName.toUpperCase())) {
console.log(searchResults);
console.log(friendResults);
$('#searchFeedback').empty();
$.each(data.events[i], function (index, value) {
$('#searchFeedback').append(output);
})
}
}
} else {
// Print results
}
} else if (eName == "" && fName != "") {
for (var a = 0; a < data.events[i].attendees.length; a++) {
if (friendResults.includes(fName.toUpperCase())) {
console.log(friendResults);
console.log(data.events[i].eName);
if (data.events[i].attendees.length != 1) {
for (var a = 0; a < data.events[i].attendees.length; a++) {
attendeeText = data.events[i].attendees.join(", ");
}
} else {
attendeeText = data.events[i].attendees;
}
if (data.events[i].attendees.length > 1) {
attendeeText = attendeeText + " are going.";
} else if (data.events[i].attendees.length == 1) {
attendeeText = attendeeText + " is going.";
} else {
attendeeText = "";
}
// Print results
}
}
}
}
}
}
/* document.getElementById("searchFeedback").innerHTML =
"<h4 class='eName'>" + data.events[i].eName + " • " + data.events[i].date + "</h4> <p class='eDesc'>" + data.events[i].description + "<br><sub>" + attendeeText + "<a class='event' onclick='openEventLink(" + i + ");' href=''><b> Check it out here.</b> </a></sub></p><br>"; */
</script>
非常感谢！
编辑：这是我的数据库的结构。里面还有很多东西，但这里是相关的部分。
var data = {
"events": [
{
"eName": "The Dalek Invasion of Earth",
"date": "6.5.2017",
"time": "10-15",
"description": "People assume that time is a strict progression of cause-and-effect... but actually, from a non-linear, non-subjective viewpoint, it's more like a big ball of wibbly-wobbly... timey-wimey... stuff. It is! It's the city of New New York! Strictly speaking, it's the fifteenth New York since the original, so that makes it New-New-New-New-New-New-New-New-New-New-New-New-New-New-New New York. Goodbye...my Sarah Jane! Yeah? Well I'm the Lord of Time. Black tie...Whenever I wear this, something bad always happens.",
"attendees": ["Jack Harkness", "Rose Tyler"],
"eLink": "http://tardis.wikia.com/wiki/The_Dalek_Invasion_of_Earth_(TV_story)"
},
{
"eName": "The Day of the Doctor",
"date": "7.5.2017",
"time": "15-18",
"description": "I'm sorry. I'm so sorry. There's something else I've always wanted to say: Allons-y, Alonso! I don't want to go. Allons-y! What? What?! WHAT?! It is! It's the city of New New York! Strictly speaking, it's the fifteenth New York since the original, so that makes it New-New-New-New-New-New-New-New-New-New-New-New-New-New-New New York. Oh, yes. Harmless is just the word: that's why I like it! Doesn't kill, doesn't wound, doesn't maim. But I'll tell you what it does do: it is very good at opening doors!",
"attendees": ["Amelia Pond", "Donna Noble"],
"eLink": "http://tardis.wikia.com/wiki/The_Day_of_the_Doctor_(TV_story)"
}
]
};
Edit2：如果有帮助，我也会添加表单的 HTML。
<div class="eventSearch">
<h2>Search for events</h2>
<form id="login" onsubmit="return eventSearch()">
<b>By event name:</b> <input type="text" name="ename" id="ename" size="56" placeholder="i.e. The Time War"><br>
<b>By a friend's name:</b> <input type="text" name="fname" id="fname" size="50" placeholder="i.e. Rose Tyler"><br><br>
<input type="radio" name="dates" value="allDates" checked> All events<br>
<input type="radio" name="dates" value="pastDates"> Past events<br>
<input type="radio" name="dates" value="futureDates"> Future events<br><br>
<button type="submit" id="confSearch" name="confSearch" onclick="event.preventDefault(); eventSearch();"><b>Search</b></button><br><br>
</form>
<div id="searchFeedback"></div>
甚至另一个编辑：为了进一步澄清，这是我网页的实时版本：http://users.metropolia.fi/~natalisu/Event%20calendar/main.html
【问题讨论】：
-
可能因为
$('#searchFeedback').empty();，它的打印才最后？ -
删除该行没有任何区别，所以不能那样。
-
好的，那么
data.events[i]是什么？可以在这里展示一下吗？ -
我会把它添加到帖子中。一秒钟！
-
attendeeText的用途是什么？和friendResults?
