在Java中检索Google的搜索结果

答案：   
客户端的javascript： 

<script language="javascript"> 
var theURL = "/examples/servlet/MyGoogleSearchServlet?search="; 
var http = getHTTPObject();  

function handleHttpResponse() { 
if (http.readyState == 4) { 
    GoogleSearchResults.innerHTML = http.responseText; 
} 
} 

function updateGoogleResults(formElement) { 
var searchQuery = document.forms[0].elements[formElement].value; 
http.open("GET", theURL + escape(searchQuery), true); 
http.onreadystatechange = handleHttpResponse; 
http.send(null); 
} 

function getHTTPObject() { 
var xmlhttp; 
try { 
    xmlhttp = new ActiveXObject("Msxml2.XMLHTTP"); 
} catch (e) { 
     try { 
        xmlhttp = new ActiveXObject("Microsoft.XMLHTTP"); 
     } catch (E) { 
        xmlhttp = false; 
     } 
} 

if (!xmlhttp && typeof XMLHttpRequest != ’undefined’) { 
    try { 
     xmlhttp = new XMLHttpRequest(); 
    } catch (e) { 
     xmlhttp = false; 
    } 
} 

return xmlhttp; 
} 
</script>

上一个：JSP用中收集数据:javascript 实现输入多行动态输入
下一个：Java和javac这两个SUN公司的路盲
