Question

我正在添加一个专为joomla K2模块设计的地图系统。 Joomla系统当前使用以下代码输出每个项目的信息。

<ul>
    <?php foreach ($item2->extra_fields as $key=>$extraField): ?>
    <?php if($extraField->value != ''): ?>
        <li class="<?php echo ($key%2) ? "odd" : "even"; ?> type<?php echo ucfirst($extraField->type); ?> group<?php echo $extraField->group; ?>">
        <?php if($extraField->type == 'header'): ?>
            <h4 class="itemExtraFieldsHeader"><?php echo $extraField->name; ?></h4>
        <?php else: ?>
            <span class="itemExtraFieldsLabel"><?php echo $extraField->name; ?>:</span>
            <span class="itemExtraFieldsValue"><?php echo $extraField->value; ?></span>
        <?php endif; ?>
        </li>
        <?php endif; ?>
<?php endforeach; ?>
</ul>

输出如下所示：

名字：乔治
姓氏：Ramsay
公园区：宁静花园
埋葬地块：D15

现在在一个名为default.php的文件中，我输入以下代码来显示地图。现在这样做了，我需要它在地图中创建一个弹出窗口，显示每个项目/人的信息。我计划使用前面提到的PHP代码执行此操作。下面是一个示例http://visuarch.net/map/dovecot-map.html

<link rel="stylesheet" href="http://cdn.leafletjs.com/leaflet-0.6.4/leaflet.css" />
    <!--[if lte IE 8]>
    <link rel="stylesheet" href="http://cdn.leafletjs.com/leaflet-0.6.4/leaflet.ie.css" />
    <![endif]-->

    <script src="http://cdn.leafletjs.com/leaflet-0.6.4/leaflet.js"></script>
    <script>
      function init() {
        var mapMinZoom = 3;
        var mapMaxZoom = 8;
        var map = L.map('map', {
          maxZoom: mapMaxZoom,
          minZoom: mapMinZoom,

        }).setView([70, -100], mapMaxZoom);

        var mapBounds = new L.LatLngBounds(
            map.unproject([0, 27136], mapMaxZoom),
            map.unproject([50176, 0], mapMaxZoom));

        map.fitBounds(mapBounds);
        L.tileLayer('http://visuarch.net/map/{z}/{x}/{y}.png', {
          minZoom: mapMinZoom, maxZoom: mapMaxZoom,
          bounds: mapBounds,
          attribution: 'Copyright © 2014 Dovecot of St. James Memorial Park.',
          noWrap: true          
        }).addTo(map);
         map.attributionControl.setPrefix('');

         var plotset3 = [
    [80.1261, -101.7334],
    [80.93535, -90.54932],
    [78.90816, -85.979],
    [77.82332, -96.45996]
];

var plotset4 = [
    [69.95291, -57.78809],
    [68.22052, -69.16992],
    [70.83025, -73.125],
    [72.44879, -61.25977]
];

var plotset5 = [
    [68.24497, -68.18115],
    [68.19605, -60.6665],
    [66.80057, -60.64453],
    [66.86972, -68.20312]
];

var plotset6 = [
    [66.19601, -67.03857],
    [66.39036, -58.97461],
    [60.72694, -53.23975],
    [59.84481, -56.88721],
    [59.22093, -56.25],
    [58.43623, -59.43604]
];


var plotset = L.polygon([ plotset3, plotset4, plotset5, plotset6], {
    color: "#000",
    weight: 1,
}).addTo(map);
    var popup = L.popup()
    .setLatLng([73.64017, -100.32715])
    .setContent( "<h4><center><b>JOHN DOE</b></center></h4> <center><img src='http://visuarch.net/dovecot/media/k2/items/cache/48ee1e8a0a8f50dce4f8cb9ab418e211_XS.jpg' border='1px'> </center><br>Section:<b> Park Section</b> <br> Plot ID:<b> J15</b>"


                      )

    .openOn(map);
      }

      jQuery(document).ready(function() {
            init();
      });

    </script>

这是我用于示例的代码：

var popup = L.popup()
    .setLatLng([73.64017, -100.32715])
    .setContent( "<h4><center><b>JOHN DOE</b></center></h4> <center><img src='http://visuarch.net/dovecot/media/k2/items/cache/48ee1e8a0a8f50dce4f8cb9ab418e211_XS.jpg' border='1px'> </center><br>Section:<b> Park Section</b> <br> Plot ID:<b> J15</b>")
    .openOn(map);

我只需要知道如何在.setContent部分使用php来输出我需要的信息。

请帮忙!!!

尽可能详细，我对javascript不太满意。

感谢。

我弄清楚了，见下文：

var content = "<ul>";
        <?php foreach ($item2->extra_fields as $key=>$extraField): ?>
            <?php if($extraField->value != ''): ?>
            content += "<li class='<?php echo ($key%2) ? 'odd' : 'even'; ?> type<?php echo ucfirst($extraField->type); ?> group<?php echo $extraField->group; ?>'>";
                <?php if($extraField->type == 'header'): ?>
                content += "<h4 class='itemExtraFieldsHeader'><?php echo $extraField->name; ?></h4>";
                <?php else: ?>
                content += "<span class='itemExtraFieldsLabel'><?php echo $extraField->name; ?>:</span>";
                content += "<span class='itemExtraFieldsValue'><?php echo $extraField->value; ?></span>";
                <?php endif; ?>
            content += "</li>";
            <?php endif; ?>
        <?php endforeach; ?>
    content += "</ul>";

var popup = L.popup()
.setContent(content).openOn(map);

如何使<！ - ？php if语句在<script - >中工作
