1:找到uploads/templets/default/head.htm
2:找到
<inputname=”q”type=”text”class=”search-keyword”id=”aa”value=”在这里搜索…”onfocus=”if(this.value==’在这里搜索…’){this.value=”;}” onkeydown=”document.getElementById(‘ssxlk’).style.display=’block’;” oninput=”_getvalue()” onblur=”if(this.value==”){this.value=’在这里搜索…’;}”/>
添加 autocomplete=”off”系统input默认autocomplete为on
3:在相应位置添加一个divid=”ssxlk”；
4:添加javascript代码:
<scripttype=”text/javascript”src=”ajax.js”></script>
<scripttype=”text/javascript”>
function_getvalue()
{
varres=”id=”+document.getElementById(‘aa’).value;
//vargvalue=document.getElementByID().value;
getajax(‘ssxxl.php’,res,b);
}
functionb(a)
{
if(document.getElementById(‘aa’).value==”)
{
document.getElementById(‘ssxlk’).innerHTML=”;
}
else
{
document.getElementById(‘ssxlk’).innerHTML=a;
}
//alert(a);
}
</script>
5：ajax.js页面：
functiongetajax(url,j,responsefunction){
if(url){
varxhr=ajax();
xhr.open(“POST”,url,true);
xhr.onreadystatechange=function(){
if(xhr.readyState==4){
if(xhr.status==200){
responsefunction(unescape(xhr.responseText));
}else{
alert(“页面读取失败”);
}
}
};
xhr.setRequestHeader(“Content-Type”,”application/x-www-form-urlencoded;”);
xhr.send(j);//发送请求
}else{
alert(“未知错误，请查识”);
}
}
functionajax(){
varhttp_request;
if(window.XMLHttpRequest){
http_request=newXMLHttpRequest();
if(http_request.overrideMimeType){
http_request.overrideMimeType(“text/xml”);
}
}elseif(window.ActiveXObject){
try{
http_request=newActiveXObject(“Msxml2.XMLHttp”);
}catch(e){
try{
http_request=newActiveXobject(“Microsoft.XMLHttp”);
}catch(e){
}
}
}
if(!http_request){
window.alert(“创建XMLHttp对象失败！”);
returnfalse;
}
returnhttp_request;
}
6：ssxxl.php页面
<?php
mysql_connect(‘localhost’,’root’,’root’);
mysql_select_db(‘dedecms’);
mysql_query(‘setnamesutf8’);
$sql=”select`typename`from`dede_arctype`where`typename`like’%”.$_POST[‘id’].”%’limit0,9;”;
//print_r($sql);
$result=mysql_query($sql);
if($row=mysql_fetch_array($result))
{
do
{
echo$row[0];
echo”<br/>”;
}
while($row=mysql_fetch_array($result));
}
//echo’aaaaaa’;
?>
页面效果为:
家门前的那条小路，到底通向了什么样的远方呢？
