自定義工具完全教程

1、自定義工具完全教程（原創(chuàng)）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=2一般寫法如下：FacesContext fcxt=WebUtil.getFacesContext();/得到DocumentDocument doc=XMLUtil.newDocument();/寫入Element resp=XMLUtil.createElement(doc, response,null, null);/寫入自定義內(nèi)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.系統(tǒng)預(yù)定義的工具操作類EsriMapPoint 點(diǎn)選EsriMapLine 線EsriMapRectangle 四邊形EsriMapCircle 圓EsriMapOval 橢圓EsriMapPolyline 多線EsriMapPolygon 多邊形EsriMapPan 移動 只需要在JSP的Tag a:tool 的屬性clientAction 中寫入工具操作類即可。對應(yīng)Server端的幾何形狀使用預(yù)定義MapTo

4、olItem類回調(diào)函數(shù)的加入：使用預(yù)定義類時，系統(tǒng)會調(diào)用一個總的回調(diào)函數(shù)：EsriCcessPostBack()而EsriControls定義如下(esri_core.js510)：var EsriControls = new function() var postBackTagHandlers = new Array(); this.addPostBackTagHandler = function(tagName, handler)./根據(jù)返回xml的某tag調(diào)用處理函數(shù) 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); . 說明只要根據(jù)返回值的TagName登記一下相應(yīng)處理函數(shù)，processPostBack就會處理：服務(wù)器端返回值如為： 那么在頁面body的onload加入：EsriControls.addPos
