1.页面的前进后退：
<input
type=button value=刷新
onclick="window.location.reload()">
<input
type=button value=前进
onclick="window.history.go(1)">
<input
type=button value=后退
onclick="window.history.go(-1)">
<input
type=button value=前进
onclick="window.history.forward()">
<input
type=button value=后退
onclick="window.history.back()">
如果是图片链接<a href="javascript:history.go(-1)">pic</a>
3.页面上面控件规定时间内显示：
<SCRIPT language=javascript
type=text/javascript>
function disappear(){
var nowDate = new Date();
var month = nowDate.getMonth()+1;
var nowHour = nowDate.getHours();
var date = nowDate.getDate();
if(month == 7 &&
17<=date && date <=21){
var
divElement = document.getElementById("divbox");
if(date
== 21 && nowHour >12){
divElement.style.display="none";
}else{
divElement.style.display="block";
}
}
}
4.锚点的设置
<a href="#huifutiezi">
相当于设置锚点，点击直接跳转到下面这个a的位置
下面设置<a>
<a name="huifutiezi" id="huifutiezi"></a>
3.jquey的使用，异步提交
function doSubmit(){
var content = document.fasong.cl_cont2.value;
var code = document.fasong.yzm.value;
var artId = document.fasong.fa_Id.value;
var numTest = /^/d{4}$/;
var parten = /^/s*$/;
if((content=="")||(parten.test(content))||
trim(content) == ""){
alert("回复内容不能为空");
return false;
}
if(content.length>1000){
alert("您输入的内容太长，多余的内容将不会提交！");
return false;
}
if(code.length == 0){
alert("嗨！您还没有输入验证码呢，无法回复帖子！");
return false;
}else if(!numTest.test(code)){
alert("对不起，您输入的图形验证码有误，请重新输入！");
document.fasong.yzm.value = "";
return false;
}else{
$.ajax({
url: "/fetion/addFetionReArt.action",
data:
$('#fasong').formSerialize(),
type:
'POST',
success:
function(data){
if(!data){
location.href="/front/register/login.jsp";
}else{
var
dd =
data.substring(0,4);
if(dd=="回复成功"){
alert(dd);
var dqy = data.substring(4);
document.fasong.cl_cont2.value = "";
location.href="/fetion/goFetionArt.action?fa_Id="+artId+"&flag=1&dqy="+dqy;
//location.href 是直接调用这个链接，可用页面跳转用；
}
else{
alert(data);
show(document.getElementById('random'));
document.fasong.yzm.value = "";
}
}
}
});
}
}
这个data是从action通过toclient方法返回回来的
/**
* 返回客户端信息
*
@param msg
*
@return
*/
private void toClient(String msg) {
HttpServletResponse
response = ServletActionContext.getResponse();
response.setCharacterEncoding("UTF-8");
try
{
PrintWriter out = response.getWriter();
out.write(msg);
out.flush();
out.close();
}
catch (IOException e) {
e.printStackTrace();
}
}
