1.用ajax post數(shù)據(jù)到后臺(tái)頁面后，接著要重新連接數(shù)據(jù)庫，別以為用之前的session連接過就可以了
2.為了處理返回亂碼的問題，我添加了header("Content-Type:text/html;charset=GB2312");就可以正常顯示了，后來在firefox下檢驗(yàn)，卻提示我下載這個(gè)網(wǎng)頁，上網(wǎng)搜了不少資料，得到一個(gè)模糊的認(rèn)識(shí)就是網(wǎng)頁代碼有語法錯(cuò)誤，firefox為了安全起見不會(huì)直接顯示而是提示下載，我重新檢查了剛才那條語句，發(fā)現(xiàn)自己多寫了個(gè)“/”,把它去掉后問題就解決了，哈哈，所以遇到這樣的問題，好好檢查一下html tag吧，畢竟firefox可不像ie那樣smart
3.最后說一句，做web site的開發(fā)者，要負(fù)責(zé)任，別以為在ie下測(cè)試通過就萬事大吉，畢竟不是所有人都用ie，還得要在別的瀏覽器下多做測(cè)試，這樣才顯示出你的專業(yè)水準(zhǔn)
ajax腳本：
復(fù)制代碼 代碼如下:
<script>
function viewpage(p){
if(window.XMLHttpRequest){
var xmlReq = new XMLHttpRequest();
} else if(window.ActiveXObject) {
var xmlReq = new ActiveXObject('Microsoft.XMLHTTP');
}
var formData = "page="+p;
xmlReq.onreadystatechange = function(){
if(xmlReq.readyState == 4){
document.getElementById('content2').innerHTML = xmlReq.responseText;
}
}
xmlReq.open("post", "hotel_list.php", true);
xmlReq.setRequestHeader("Content-Type", "application/x-www-form-urlencoded");
xmlReq.send(formData);
return false;
}
</script>
