ajax+javascript刷新想要的数据
此主页http://www.zc36.com就是用到ajax，可参考里面的javascript
如调用处理的文件内是需设置字符集否则会乱码
php的代码是：
header('Content-Type:text/html;charset=GB2312');//此句之前什么东东都不能输出如回车换行等
<script language='JavaScript'>
var http_request = false;
var postStr=null;
function send_request(url){//调用处理_ie,firefox通过
http_request = false;
if(window.XMLHttpRequest){
http_request = new XMLHttpRequest();
if(http_request.overrideMimeType)
http_request.overrideMimeType('text/xml');
}else if(window.ActiveXObject){
try{
http_request = new ActiveXObject('Msxml2.XMLHTTP');
}catch(e){
try{
http_request = new ActiveXObject('Microsoft.XMLHTTP');
}catch(e){}
}
}
if(!http_request){
alert('创建失败');
return false;
}
http_request.onreadystatechange = processRequest;//设置调用的函数名
http_request.open('GET',url,true);//提交的方式跟表单提交类型一样
http_request.setRequestHeader('Content-Type','application/x-www-form-urlencoded');
http_request.send(postStr);
}
function processRequest(){
num=http_request.readyState;
if(num==4){
num=http_request.status;
if(num==200){
alert(http_request.responseText);//取得返回的内容
}else{
alert("失败");
}
}else{
alert("加载中");
}
}
</script>
