在MapGuide 的Fusion Viewer的选择面板中显示超链接

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(/&lt;/g,     "<");

	s =  s.replace(/&nbsp;/g,   " ");

	s =  s.replace(/'/g,        "\'");

	s =  s.replace(/&quot;/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。
