PHP中遇到AJAX的问题
<?php<br>header("Content-Type:html/text;Charset=utf-8");<br>$name = $_POST['name'];<br>$email = $_POST['email'];<br>$comment = $_POST['comment'];<br>$fh = @fopen("14-6.txt","ab");<br>fwrite($fh,"姓名:".$name,strlen($name));<br>fwrite($fh,"email:".$email,strlen($email));<br>fwrite($fh,"评论:".$comment,strlen($comment));<br>fclose($fh);<br>echo 1;<br>?>function $(id){<br> return document.getElementById(id);<br>}<br>function addcomment(){<br> var url = "14-6.php";<br> var status = document.getElementById("divmsg");<br> status.value="正在提交》》》";<br> var param = "name="+$("name").value+"email="+$("email").value+"comment="+$("comment").value;<br> xmlhttp_request.onreadystatechange = function(){<br> if(xmlhttp_request.readyState==4 && xmlhttp_request.status == 200){//相应完全显示信息<br> alert (xmlhttp_request.responseText);<br> if(xmlhttp_request.responseText == "1"){<br> status.value = "发表成功！！";<br> $("name").value="";<br> $("email").value="";<br> $("comment").value="";<br> }else{<br> status.value = "发表失败！请重新发表！";<br> }<br> } <br> }<br> xmlhttp_request.open("POST",url,true);<br> xmlhttp_request.setRequestHeader("Content-Type","application/x-www-form-urlencoded");//设置头信息<br> xmlhttp_request.send(param);<br>}不知道为什么，这个responsetext返回的是一大面的html代码.
