关于PHP+AJAX查询提示“正在查找...”的问题

我用coldfusion的，不过ajax这一块差不多，给你这个参考一下吧，
大概思路就是在页面添加一个'loading...please wait'层，读数据的时候设置可见，完成时设置不可见。里面$是prototype的document.getElementById的缩写，
可以在提交的时候调用DWREngine.setPreHook的内容，status == 200的时候用DWREngine.setPostHook，不知道这样能不能明白。
DWRUtil.useLoadingMessage = function()
{
    var disabledZone = document.createElement('div');
    disabledZone.setAttribute('id', 'disabledZone');
    disabledZone.style.position = "absolute";
    disabledZone.style.zIndex = "1000";
    disabledZone.style.left = "0px";
    disabledZone.style.top = "0px";
    disabledZone.style.width = "100%";
    disabledZone.style.height = "100%";
    document.body.appendChild(disabledZone);    var messageZone = document.createElement('div');
    messageZone.setAttribute('id', 'messageZone');
    messageZone.style.position = "absolute";
    messageZone.style.top = "0px";
    messageZone.style.right = "0px";
    messageZone.style.background = "red";
    messageZone.style.color = "white";
    messageZone.style.fontFamily = "Arial,Helvetica,sans-serif";
    messageZone.style.padding = "4px";
    disabledZone.appendChild(messageZone);    var text = document.createTextNode('Loading');
    messageZone.appendChild(text);    $('disabledZone').style.visibility = 'hidden';    DWREngine.setPreHook(function() { $('disabledZone').style.visibility = 'visible'; });
    DWREngine.setPostHook(function() { $('disabledZone').style.visibility = 'hidden'; });
};

郁闷了 ff里面正常 ie里面怎么都超时，不行 -.-
顶楼上的php，呵呵虽然php不会：）可以参考一下我的，至少ie肯定是通过的，
这个是最简单的例子，核心就是这个两个pushAjax()和alertContents()，pushAjax()用来处理请求，url是你的查询记录的文件，parameters是需要传入文件的参数，pTag是输出的标记位置，alertContents()用来把得到的内容输出到当前页面，比如：User Location<div id ="div_userLoc"></div>
<input type="button" onclick="javascript:pushAjax('mvc/view/vGetUserLocation.cfm','?cid=xxx','div_userLoc');" value="Get Location">
function pushAjax(url, parameters, pTag) {
document.getElementById(pTag).innerHTML = '<img src="images/loading.gif" alt="" align="absmiddle" valign="bottom"/>Processing ...'; //添加'正在读取'的标记，loading.gif是一个读取的小动画
  http_request = false;
  if (window.XMLHttpRequest) { // Mozilla, Safari,...
http_request = new XMLHttpRequest();
if (http_request.overrideMimeType) {
// set type accordingly to anticipated content type
//http_request.overrideMimeType('text/xml');
http_request.overrideMimeType('text/html');
}
  } else if (window.ActiveXObject) { // IE
try {
http_request = new ActiveXObject("Msxml2.XMLHTTP");
} catch (e) {
try {
   http_request = new ActiveXObject("Microsoft.XMLHTTP");
} catch (e) {}
}
  }
  if (!http_request) {
alert('Cannot create XMLHTTP instance');
return false;
  }
  http_request.onreadystatechange = function(){ alertContents(pTag) };
  http_request.open('GET', url + parameters, true);
  http_request.send(null);
}function alertContents(pTag) {
  if (http_request.readyState == 4) {
if (http_request.status == 200) {
//alert(http_request.responseText);
result = http_request.responseText;
document.getElementById(pTag).innerHTML = result;
} else {
alert('There was a problem with the request.');
}
  }
}
做个更简单的。
给你个图片，gif动画的图片，当开始的时候，向用户浏览器输出该图片，然后你去处理那几百万条数据，等处理完毕后，在把原先的gif图片隐藏掉即可。程序开始时输出如下信息：
<div id='waitme' name='waitme'>
<img src='waitme.gif'>
</div>接着，处理你的需要很长时间才可以处理完的东东
处理完毕后：
<script>
document.all('waitme').style.display=none;
</script>
输出你的信息
好了，效果出来了吧。当然了，如果不用gif图片的话，你写javascript也可以。
