功能：動態(tài)指定js函數(shù)，實際上這個效果不是很有用，這里就做一個記錄而已，參考代碼如下：

package com; import com.gargoylesoftware.htmlunit.BrowserVersion;import com.gargoylesoftware.htmlunit.ScriptResult; import com.gargoylesoftware.htmlunit.WebClient; import com.gargoylesoftware.htmlunit.html.DomElement; import com.gargoylesoftware.htmlunit.html.DomNodeList; import com.gargoylesoftware.htmlunit.html.HtmlAnchor; import com.gargoylesoftware.htmlunit.html.HtmlElement; import com.gargoylesoftware.htmlunit.html.HtmlPage; import com.gargoylesoftware.htmlunit.javascript.host.event.Event; public class EBayHU {public static void main(String[] args) { WebClient webClient = new WebClient(BrowserVersion.CHROME); //創(chuàng)建一個webclient webClient.getOptions().setJavaScriptEnabled(true); // 啟動JS webClient.getOptions().setUseInsecureSSL(true);//忽略ssl認證 webClient.getOptions().setCssEnabled(false);//禁用Css，可避免自動二次請求CSS進行渲染 webClient.getOptions().setThrowExceptionOnScriptError(false);//運行錯誤時，不拋出異常 webClient.setAjaxController(new NicelyResynchronizingAjaxController());// 設(shè)置Ajax異步try {HtmlPage page=webClient.getPage("url");webClient.waitForBackgroundJavaScript(10000);HtmlElement propic =page.getHtmlElementById("viEnlargeImgLayer_layer_fs");DomNodeList<HtmlElement> picnodes=propic.getElementsByTagName("img");for(int m=0;m<picnodes.size();m++){HtmlElement pic=picnodes.get(m);System.out.println(pic.asXml());//響應(yīng)事件//Event event=new Event();//event.setEventType(Event.TYPE_KEY_DOWN);//HtmlPage hpm=pic.click(event); //bpic.fireEvent(event);//執(zhí)行js String hrefValue = "javascript:add(1,1,'+');";ScriptResult s = page.executeJavaScript(hrefValue);//執(zhí)行js方法HtmlPage hpm=(HtmlPage) s.getNewPage();//獲得執(zhí)行后的新page對象 webClient.waitForBackgroundJavaScript(10000);HtmlElement lpic=hpm.getHtmlElementById("viEnlargeImgLayer_img_ctr");System.out.println(lpic.asXml()); } } catch (IOException e) {// TODO Auto-generated catch blocke.printStackTrace();}}
