Question

我试图在弹出框中显示XML数据。现在，它在弹出窗口中显示XML文件数据的所有数据。但是实际上，当我单击open modal1时，只需要从XML文件中加载第一个数据集（array-0）。另外，当单击打开modal2时，只需要从XML加载第二个数据集（array-1），如何使用js循环来完成呢？

这是我的代码。

data.xml

<?xml version="1.0"?>
<paintings>
  <painting>
    <title>test</title>
    <artist>Test Artist</artist>
    <image>https://upload.wikimedia.org/wikipedia/commons/thumb/5/52/Liliumbulbiferumflowertop.jpg/220px-Liliumbulbiferumflowertop.jpg</image>
    <price>850</price>
  </painting>

  <painting>
    <title>test2</title>
    <artist>Test Artist2</artist>
    <image>https://upload.wikimedia.org/wikipedia/commons/thumb/5/52/Liliumbulbiferumflowertop.jpg/220px-Liliumbulbiferumflowertop.jpg</image>
    <price>8503</price>
  </painting>
</paintings>

index.html

<div class="container">


<a href="#openModal1" id="openModalBtn">open modal1</a>
<a href="#openModal2" id="openModalBtn">open modal2</a>


<div id="openModal1" class="modalDialog">
    <div>
       <input class="getAssignment2" type="button" value="Previous" id="prev">
        <input class="getAssignment" type="button" value="Next" id="next">
    <a href="#close" title="Close" class="close">X</a>
   <div id="container"></div>
   </div>
</div>

</div>

JavaScript代码

$(document).ready(function(){
        $.ajax({
            type:"GET",
            url:"data.xml",
            dataType:"xml",
            success:xmlParser
        });
    });

    function xmlParser(xml){
        $(xml).find("painting").each(function(){
            $("#container").append(
                '<div class="painting"><img src="' + $(this).find("image").text() + '" width="200" height="225" alt="' + $(this).find("title").text() + '" /> <br/> <div class="title">' + $(this).find("title").text() + '<br/>$' + $(this).find("price").text() + '</div></div>');

        });
    }

	    function xmlParser(xml,id){
	        	console.log($(this).find("title").text())
	            $("#container-"+parseInt(id)).append(
	                '<div class="painting"><img src="' + $($(xml).find("image")[parseInt(id)]).text() + '" width="200" height="225" alt="' + $($(xml).find("title")[parseInt(id)]).text() + '" /> <br/> <div class="title">' + $($(xml).find("title")[parseInt(id)]).text() + '<br/>$' + $($(xml).find("price")[parseInt(id)]).text() + '</div></div>');
