在Java中检索Google的搜索结果

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>
