其实你完全可以采用jquery的ajax方式来读取.var result = false
var thenow = new Date()
$.ajax({
type:"POST",
url:"此处为相对路径的php文件?Time="+thenow.getMilliseconds()+"M"+thenow.getSeconds()+"",
data:{id:id},
success:function(data){
}
})
如果你不用jquery
var xmlHttps = new Array(10)
var e
var EndHtml=false
//创建XMLHTTP对象
function getXMLHTTPObj()
{
var C = null
try
{
C = new ActiveXObject("Microsoft.XMLHTTP")
}
catch(e)
{
try
{
C = new ActiveXObject("Msxml2.XMLHTTP")
}
catch(sc)
{
C = null
}
}
if( !C && typeof XMLHttpRequest != "undefined" )
{
C = new XMLHttpRequest()
}
return C
}
function GetDetail(userid,id)
{
document.getElementById(id).innerHTML = ""
try
{
xmlHttps[id]=false
xmlHttps[id]= getXMLHTTPObj()
if( xmlHttps[id] )
{
var realUrl = "/Ajax.aspx?action="+id+"&userid=" + escape(userid)+"&date="+new Date().getTime()
xmlHttps[id].open("get", realUrl, true)
//设置回调函数
xmlHttps[id].onreadystatechange = function(){updatePage(id,xmlHttps[id])}
//发送请求
xmlHttps[id].send(null)
// xmlHttps.abort()
}
else
{
document.getElementById(id).innerHTML = "<font color=#ff0000>×</font>您的浏览器不支持"
}
}
catch (e)
{
document.getElementById(id).innerHTML = "<font color=#ff0000>×</font> 发生异常"
}
}
请参照下面的例子：
/*URL可以随意改*/
String uriAPI = "http://192.168.1.100:8080/test/test.jsp?u=wangyi&p=456"
/*建立HTTP Get对象*/
HttpGet httpRequest = new HttpGet(uriAPI)
try
{
/*发送请求并等待响应*/
HttpResponse httpResponse = new DefaultHttpClient().execute(httpRequest)
/*若状态码为200 ok*/
if(httpResponse.getStatusLine().getStatusCode() == 200)
{
/*读*/
String strResult = EntityUtils.toString(httpResponse.getEntity())
/*去没有用的字符*/
strResult = eregi_replace("(\r\n|\r|\n|\n\r)","",strResult)
mTextView1.setText(strResult)
}
else
{
mTextView1.setText("Error Response: "+httpResponse.getStatusLine().toString())
}
}
catch (ClientProtocolException e)
{
mTextView1.setText(e.getMessage().toString())
e.printStackTrace()
}
catch (IOException e)
{
mTextView1.setText(e.getMessage().toString())
e.printStackTrace()
}
catch (Exception e)
{
mTextView1.setText(e.getMessage().toString())
e.printStackTrace()
}
HTTP请求是指从客户端到服务器端的请求消息，包括消息首行中，对资源的请求方法、资源的标识符及使用的协议。如果HTTP/1.0服务器收到简单请求，它必须回应一个HTTP/0.9格式的简单回应。
// ajax 对象function ajaxObject() {
var xmlHttp
try {
// Firefox, Opera 8.0+, Safari
xmlHttp = new XMLHttpRequest()
}
catch (e) {
// Internet Explorer
try {
xmlHttp = new ActiveXObject("Msxml2.XMLHTTP")
} catch (e) {
try {
xmlHttp = new ActiveXObject("Microsoft.XMLHTTP")
} catch (e) {
alert("您的浏览器不支持AJAX！")
return false
}
}
}
return xmlHttp
}
// ajax post请求：
function ajaxPost ( url , data , fnSucceed , fnFail , fnLoading ) {
var ajax = ajaxObject()
ajax.open( "post" , url , true )
ajax.setRequestHeader( "Content-Type" , "application/x-www-form-urlencoded" )
ajax.onreadystatechange = function () {
if( ajax.readyState == 4 ) {
if( ajax.status == 200 ) {
fnSucceed( ajax.responseText )
}
else {
fnFail( "HTTP请求错误！错误码："+ajax.status )
}
}
else {
fnLoading()
}
}
ajax.send( data )
}
