自定义工具完全教程

1、自定义工具完全教程（原创）1/2附件1.JPG (13.16 KB) 2007-11-19 10:41 What get us into trouble is not what we dont know, Its what we are know for sure that just aint so. 0F7D9BDFF402A9DA36?wname=esriWebSession&id=overview3564915&uniqueId=0 true 1471489999 Map0 1020 600 /mygis/mimedata;jsessionid=51FE49E491119D0F7D9BD

2、FF402A9DA36?wname=esriWebSession&id=map26795772&uniqueId=2一般写法如下：FacesContext fcxt=WebUtil.getFacesContext();/得到DocumentDocument doc=XMLUtil.newDocument();/写入Element resp=XMLUtil.createElement(doc, response,null, null);/写入自定义内容Element addr=XMLUtil.createElement(address, , resp);addr.setAttribute(nam

3、e, name);/callbackAJAXUtil.writeResponse(fcxt, doc);/跳出JSF其他phrasefcxt.responseComplete();五.系统预定义的工具操作类EsriMapPoint 点选EsriMapLine 线EsriMapRectangle 四边形EsriMapCircle 圆EsriMapOval 椭圆EsriMapPolyline 多线EsriMapPolygon 多边形EsriMapPan 移动 只需要在JSP的Tag a:tool 的属性clientAction 中写入工具操作类即可。对应Server端的几何形状使用预定义MapTo

4、olItem类回调函数的加入：使用预定义类时，系统会调用一个总的回调函数：EsriCcessPostBack()而EsriControls定义如下(esri_core.js510)：var EsriControls = new function() var postBackTagHandlers = new Array(); this.addPostBackTagHandler = function(tagName, handler)./根据返回xml的某tag调用处理函数 cessPostBack = function(xh) if (xh != nul

5、l & xh.readyState = 4 & xh.status = 200) var xml = xh.responseXML; /alert(xh.responseText); var formTags = xml.getElementsByTagName(form); . for (var h=0;hpostBackTagNames.length;h+) var tagName = postBackTagNamesh; var tags = xml.getElementsByTagName(tagName); for (var i=0;itags.length;i+) for (var l=0;lpostBackTagHandlerstagName.length;l+) postBackTagHandlerstagNamel(tags.item(i), eventSources); . 说明只要根据返回值的TagName登记一下相应处理函数，processPostBack就会处理：服务器端返回值如为： 那么在页面body的onload加入：EsriControls.addPos
