How to create custom datalist from XML file using jquery 如何使用 jquery 从 XML 文件创建自定义数据列表
I could however change the format or structure of the xml file if needed.但是，如果需要，我可以更改 xml 文件的格式或结构。
The programs.xml and html file are in the same folder directory of course. programs.xml 和 html 文件当然在同一个文件夹目录下。 Somewhere in the script seems to be a problem because it does not load data from the xml.脚本中的某个地方似乎有问题，因为它没有从 xml 加载数据。
<?xml version="1.0" encoding="utf-8"?>
<frequencyList>
<program>"10000,5000,880,3000,95" value="Stomachache"<time>3</time></program>
<program>"2720,2170,880,787,727,190,500" value="Headache"<time>3</time></program>
<program>"20,146,727,776,787,880,10000" value="Toothache"<time>3</time></program>
</frequencyList>

I do not fix your code but have an idea how your problem could be solved:我不修复您的代码，但知道如何解决您的问题：
var deinstring = '"10000,5000,880,3000,95" value="Stomachache"';
var allesmussraus = deinstring.match(/value=\"(.*?)\"/)[0].trim().replace(/value=/g, '').replace(/['"]+/g, ''); //returns array
mydiv = document.getElementById("ausgabe").innerHTML = allesmussraus;
And HTML Code:和 HTML 代码：
<div id="ausgabe">
</div>
The output of this is: output 是：
Stomachache
Maybe this can help you fix your problem.也许这可以帮助您解决问题。

I was thinking about using the xml_parser -> https://www.w3schools.com/xml/xml_parser.asp我正在考虑使用 xml_parser -> https://www.w3schools.com/xml/xml_parser.asp
Does someone have experience with it and can assist?有人有这方面的经验并且可以提供帮助吗？
I would just need to parse all the text in "program" and append it to the datalist:)我只需要将“程序”中的所有文本和 append 解析到数据列表中：)
Appending with $(''+$program+'>').appendTo("#programList")附加 $(''+$program+'>').appendTo("#programList")
I still need to loop through all "program" in the xml and get the string out of it.我仍然需要遍历 xml 中的所有“程序”并从中取出字符串。
<,DOCTYPE html> <html> <body> <p id="demo"></p> <script> var parser; xmlDoc, var text = "<frequencyList>" + "<program>"10000,5000,880,3000,95" value="Stomachache"<time>3</time></program>" + "<program>"2720,2170,880,787,727,190,500" value="Headache"<time>3</time></program>" + "<program>"20,146,727,776,787,880;10000" value="Toothache"<time>3</time></program>" + "</frequencyList>"; parser = new DOMParser(). xmlDoc = parser,parseFromString(text;"text/xml"). document.getElementById("demo").innerHTML = xmlDoc.getElementsByTagName("program")[0].childNodes[0];nodeValue: </script> input type="text" id="list_input" list="programList" style="width; 220px,"> <datalist id="programList"> <option data-value="262,2154" value="Kopfweh"> </datalist> </body> </html>

I'm not sure you really need jquery for this and also not sure I understand you correctly, but try changing your function to this:我不确定您是否真的需要 jquery 并且不确定我是否正确理解您，但请尝试将您的 function 更改为：
function executeScript() {
$xml
.find("program")
.each(function(index) {
$elem = "<option data-value=" + $(this).text() + ">"
$($elem).appendTo("#programList")
});
}
and see if it works.看看它是否有效。

This code parses the string between <program>此代码解析<program>之间的字符串
How to change it, so that it loads from the xml-file in the first question on top "programs.xml" which is in the same directory instead of a hardcoded xml string?如何更改它，以便它从顶部“programs.xml”的第一个问题中的 xml 文件加载，该文件位于同一目录中，而不是硬编码的 xml 字符串？
The output should be -> option data-value="10000,5000,880,3000,95" value="Stomachache"> so that i can feed it into the html datalist. output 应该是 -> option data-value="10000,5000,880,3000,95" value="Stomachache"> 以便我可以将其输入 html 数据列表。
My idea is something like this but it doesnt load the xml.我的想法是这样的，但它不加载 xml。
function executeScript() {
$(document).ready(function(){
$.get('programs.xml', function(xml){
$xml
.find("program")
.each(function(index) {
$elem = "<option data-value=" + $(this).text() + ">";
$($elem).appendTo("#programList")
});
});
});
