Question

我试图将W3schools.com（https://www.w3schools.com/howto/howto_css_modals.asp）上找到的弹出式模式添加到每个<line>。当用户点击任何<line>时，相应的<title>，整个<description>和<footer>都会弹出。我的xml看起来像这样：

<?xml version="1.0" encoding="UTF-8"?>
<items>
    <item>
        <title>Header1</title>
        <description>
            <p>
                <line>
                    This is line 1 of description of item 1.
                </line>
                <line>
                    This is line 2 of description of item 1.
                </line>
                <line>
                    This is line 3 of description of item 1.
                </line>
            </p>
        </description>
        <footer>Footer1</footer>
    </item>
    <item>
        <title>Header2</title>
        <description>
            <p>
                <line>
                    This is line 1 of description of item 2.
                </line>
                <line>
                     This is line 2 of description of item 2.
                </line>
                <line>
                    This is line 3 of description of item 2.
                </line>
            </p>
        </description>
        <footer>Footer2</footer>
    </item>
</items>

如果我在xsl中添加<div id="myModal" class="modal">和<script>，则xsl不会产生输出。

这是我的xsl：

<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">

    <xsl:template match="/">
         <xsl:apply-templates select="items/item/title"/>
             <script>
               function para() {
               // Get the modal
                var modal = document.getElementById('myModal');

                // Get the button that opens the modal
                var p = document.getElementById("myBtn");

                // Get the <span> element that closes the modal
                var span = document.getElementsByClassName("close")[0];

                // When the user clicks the button, open the modal
                p.onclick = function() {
                modal.style.display = "block";
                 }

                // When the user clicks on <span> (x), close the modal
                 span.onclick = function() {
                  modal.style.display = "none";
                }

                // When the user clicks anywhere outside of the modal, close it
                 window.onclick = function(event) {
                    if (event.target == modal) {
                    modal.style.display = "none";
                 }
               }
             }
       </script>
    </xsl:template>

<xsl:template match="title">
   <p onclick="para()" id="myBtn">
    <xsl:apply-templates/>
   </p>

<div id="myModal" class="modal">
    <div class="modal-content">
       <div class="modal-header">
         <span class="close">&times;</span>
       <h2>Modal Header</h2>
       </div>
       <div class="modal-body">
         <p>text in the Modal</p>
       </div>
       <div class="modal-footer">
         <h3>Modal Footer</h3>
       </div>
    </div>
</div>
</xsl:template>

</xsl:stylesheet>

这是PHP：

<!DOCTYPE html>
<html>
<head>
<style>
/* The Modal (background) */
.modal {
display: none; /* Hidden by default */
position: fixed; /* Stay in place */
    z-index: 1; /* Sit on top */
    padding-top: 100px; /* Location of the box */
left: 0;
top: 0;
width: 100%; /* Full width */
height: 100%; /* Full height */
overflow: auto; /* Enable scroll if needed */
    background-color: rgb(0,0,0); /* Fallback color */
    background-color: rgba(0,0,0,0.4); /* Black w/ opacity */
}

/* Modal Content */
.modal-content {
position: relative;
    background-color: #fefefe;
margin: auto;
padding: 0;
border: 1px solid #888;
width: 80%;
    box-shadow: 0 4px 8px 0 rgba(0,0,0,0.2),0 6px 20px 0 rgba(0,0,0,0.19);
    -webkit-animation-name: animatetop;
    -webkit-animation-duration: 0.4s;
    animation-name: animatetop;
    animation-duration: 0.4s
}

</style>
</head>
<body>
<?php


    $xml = new DOMDocument;
    // Load XML file
    $xml->load('test.xml');


    // Load XSL file
    $xsl = new DOMDocument;
    $xsl->load('test.xsl');

    // Configure the transformer
    $xsltProcessor = new XSLTProcessor;

    // Attach the xsl rules
    $xsltProcessor->importStyleSheet($xsl);


    echo $xsltProcessor->transformToXML($xml);
?>

</body>
</html>

Answer 1

您使用的代码是单个模态对话，您需要扩展它以允许它与各种模态对话一起使用，这里有一个简单的Javascript / HTML / CSS组合：

var modals = {
  currentModal : null,
  openModal : function(id) {
    this.currentModal = document.getElementById(id);
    this.currentModal.style.display = 'block';
  },
  close : function() {
    if (this.currentModal != null) {
      this.currentModal.style.display = 'none';
      this.currentModal = null;
    }
  }
}


// When the user clicks anywhere outside of a modal, close it
window.onclick = function(event) {
    if (event.target == modals.currentModal) {
        modals.close();
    }
}

/* The Modal (background) */
.modal {
    display: none; /* Hidden by default */
    position: fixed; /* Stay in place */
    z-index: 1; /* Sit on top */
    left: 0;
    top: 0;
    width: 100%; /* Full width */
    height: 100%; /* Full height */
    overflow: auto; /* Enable scroll if needed */
    background-color: rgb(0,0,0); /* Fallback color */
    background-color: rgba(0,0,0,0.4); /* Black w/ opacity */
}

/* Modal Content/Box */
.modal-content {
    background-color: #fefefe;
    margin: 15% auto; /* 15% from the top and centered */
    padding: 20px;
    border: 1px solid #888;
    width: 80%; /* Could be more or less, depending on screen size */
}

/* The Close Button */
.close {
    color: #aaa;
    float: right;
    font-size: 28px;
    font-weight: bold;
}

.close:hover,
.close:focus {
    color: black;
    text-decoration: none;
    cursor: pointer;
}

<!-- Trigger/Open The Modal 1 -->
<button onclick="modals.openModal('modal1');">Open Modal 1</button>

<!-- The Modal 1 -->
<div id="modal1" class="modal">

  <!-- Modal content  1-->
  <div class="modal-content">
    <span class="close" onclick="modals.close();">&times;</span>
    <p>Some text in the Modal 1..</p>
  </div>

</div>

<!-- Trigger/Open The Modal 2 -->
<button onclick="modals.openModal('modal2');">Open Modal 2</button>

<!-- The Modal 2 -->
<div id="modal2" class="modal">

  <!-- Modal content  2-->
  <div class="modal-content">
    <span class="close" onclick="modals.close();">&times;</span>
    <p>Some text in the Modal 2..</p>
  </div>

</div>

现在您需要确保您的XSLT生成该结构，这是一个完整的样式表，可以执行此操作：

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
    version="1.0">

    <xsl:output method="html" indent="yes" version="5.1" doctype-system="about:legacy-compat"/>

    <xsl:template match="/">
        <html>
            <head>
                <title>Test</title>
                <style>
     /* The Modal (background) */
    .modal {
        display: none; /* Hidden by default */
        position: fixed; /* Stay in place */
        z-index: 1; /* Sit on top */
        left: 0;
        top: 0;
        width: 100%; /* Full width */
        height: 100%; /* Full height */
        overflow: auto; /* Enable scroll if needed */
        background-color: rgb(0,0,0); /* Fallback color */
        background-color: rgba(0,0,0,0.4); /* Black w/ opacity */
    }

    /* Modal Content/Box */
    .modal-content {
        background-color: #fefefe;
        margin: 15% auto; /* 15% from the top and centered */
        padding: 20px;
        border: 1px solid #888;
        width: 80%; /* Could be more or less, depending on screen size */
    }

    /* The Close Button */
    .close {
        color: #aaa;
        float: right;
        font-size: 28px;
        font-weight: bold;
    }

    .close:hover,
    .close:focus {
        color: black;
        text-decoration: none;
        cursor: pointer;
    }                   
                </style>
                <script>
     var modals = {
      currentModal : null,
      openModal : function(id) {
        this.currentModal = document.getElementById(id);
        this.currentModal.style.display = 'block';
      },
      close : function() {
        if (this.currentModal != null) {
          this.currentModal.style.display = 'none';
          this.currentModal = null;
        }
      }
    }


    // When the user clicks anywhere outside of a modal, close it
    window.onclick = function(event) {
        if (event.target == modals.currentModal) {
            modals.close();
        }
    }                 
                </script>
            </head>
            <body>
                <h1>Test</h1>
                <xsl:apply-templates select="items/item"/>
                <xsl:apply-templates select="items/item" mode="dialogue"/>
            </body>
        </html>
    </xsl:template>

    <xsl:template match="items/item">
        <p onclick="modals.openModal('modal{position()}');">
          <xsl:value-of select="title"/>
        </p>
    </xsl:template>

    <xsl:template match="items/item" mode="dialogue">
      <xsl:comment>The Modal <xsl:value-of select="position()"/></xsl:comment>
      <div id="modal{position()}" class="modal">
        <div class="modal-content">
          <span class="close" onclick="modals.close();">&#215;</span>
          <section>
            <xsl:apply-templates mode="dialogue"/>
          </section>
        </div>
      </div>
    </xsl:template>

    <xsl:template match="items/item/title" mode="dialogue">
      <h2>
        <xsl:apply-templates mode="dialogue"/>
      </h2>   
    </xsl:template>

    <xsl:template match="items/item/description" mode="dialogue">
      <p>
        <xsl:apply-templates mode="dialogue"/>
      </p>
    </xsl:template>

    <xsl:template match="items/item/footer" mode="dialogue">
      <h3>
        <xsl:apply-templates mode="dialogue"/>
      </h3>
    </xsl:template>

</xsl:stylesheet>

https://martin-honnen.github.io/xslt/2017/test2017091201.xml在线示例。由于您似乎想要使用PHP运行XSLT服务器端，并且只使用XSLT生成部分HTML，您显然需要对其进行调整。

至于你的改编输入XML样本，它甚至没有格式良好，所以你没有尝试过几个小时。您必须首先找到用HTML表示对话内容的方法，然后您可以简单地编写模板来创建该结构。这是一次尝试：

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
    version="1.0">

    <xsl:output method="html" indent="yes" version="5.1" doctype-system="about:legacy-compat"/>

    <xsl:template match="/">
        <html>
            <head>
                <title>Test</title>
                <style>
     /* The Modal (background) */
    .modal {
        display: none; /* Hidden by default */
        position: fixed; /* Stay in place */
        z-index: 1; /* Sit on top */
        left: 0;
        top: 0;
        width: 100%; /* Full width */
        height: 100%; /* Full height */
        overflow: auto; /* Enable scroll if needed */
        background-color: rgb(0,0,0); /* Fallback color */
        background-color: rgba(0,0,0,0.4); /* Black w/ opacity */
    }

    /* Modal Content/Box */
    .modal-content {
        background-color: #fefefe;
        margin: 15% auto; /* 15% from the top and centered */
        padding: 20px;
        border: 1px solid #888;
        width: 80%; /* Could be more or less, depending on screen size */
    }

    /* The Close Button */
    .close {
        color: #aaa;
        float: right;
        font-size: 28px;
        font-weight: bold;
    }

    .close:hover,
    .close:focus {
        color: black;
        text-decoration: none;
        cursor: pointer;
    }                   
                </style>
                <script>
     var modals = {
      currentModal : null,
      openModal : function(id) {
        this.currentModal = document.getElementById(id);
        this.currentModal.style.display = 'block';
      },
      close : function() {
        if (this.currentModal != null) {
          this.currentModal.style.display = 'none';
          this.currentModal = null;
        }
      }
    }


    // When the user clicks anywhere outside of a modal, close it
    window.onclick = function(event) {
        if (event.target == modals.currentModal) {
            modals.close();
