如果你的数据源中包含有超链接,在Ajax viewer中选中某个地物是,在选择面板中显示该要素的相关信息时是可以显示超链接的。但在Fusion Viewer中,这个特性不管用,超链接会以HTML代码的方式显示,很不好看:
解决的方法就是把HTML代码decode一下,修改 C:\Program Files\Autodesk\Autodesk Infrastructure Web Server Extension 2013\www\fusion\widgets\SelectionPanel.js 文件,在这个文件中搜索renderFeature,大概在384行附近,改为如下代码:
htmlDecode:function(str){ var s = ""; if(str.length == 0) return ""; s = str.replace(/>/g, ">"); s = s.replace(/</g, "<"); s = s.replace(/ /g, " "); s = s.replace(/'/g, "\'"); s = s.replace(/"/g, "\""); s = s.replace(/<br>/g, "\n"); return s; }, renderFeature: function() { var layerIdx = this.layerList.selectedIndex; var featureIdx = this.featureList.selectedIndex; var layerObj = this.oSelection.getLayer(layerIdx); var nProperties = layerObj.getNumProperties(); var aNames = layerObj.getPropertyNames(); var table = document.createElement('table'); var thead = document.createElement('thead'); var tr = document.createElement('tr'); var th = document.createElement('th'); th.innerHTML = OpenLayers.i18n('attribute'); tr.appendChild(th); var th = document.createElement('th'); th.innerHTML = OpenLayers.i18n('value'); tr.appendChild(th); thead.appendChild(tr); table.appendChild(thead); var tbody = document.createElement('tbody'); table.appendChild(tbody); for (var i=0; i<nProperties; i++) { var tr = document.createElement('tr'); if (i%2) { tr.className = 'oddRow'; } var th = document.createElement('th'); th.innerHTML = aNames[i]; var td = document.createElement('td'); td.innerHTML = this.htmlDecode(layerObj.getElementValue(featureIdx, i)); tr.appendChild(th); tr.appendChild(td); tbody.appendChild(tr); } this.featureDiv.innerHTML = ''; this.featureDiv.appendChild(table); }
注意htmlDecode方法后面的逗号。最后为了改更改生效,还需要更改模版文件html中的javascript指向,比如对于Slate模版,更改C:\Program Files\Autodesk\Autodesk Infrastructure Web Server Extension 2013\www\fusion\templates\mapguide\slate\index.html。
<script type="text/javascript" src="../../../lib/fusion.js"></script>
如果你想调试,请参考这个博客。以上代码在Autodesk Infrastructure Map Server 2013测试通过,对于MapGuide OpenSource应该也适用。
