网页中的“下一页”怎么实现
网页中的“下一页”实现的方法。
如下参考：
1.首先，打开HTML编辑器并创建一个新的HTML文件，如index.html。
2.在index.html中的script标签，输入js代码：
varnow=parseInt(location.href.split('?')[1].split('=')[1]);
$('body').append('a href="index?page='+ (now-1)+'"上一页/a');
$('body').append('a href="index?page='+ (now+1)+'"下一页/a');
3.在chrome浏览器中运行index.html页面，上一页和下一页的a标记将用js打印。
求键盘的所有按键对应的JS函数~~~！！！！或者提供网页键盘源代码！！
$(window).keydown(function(event){
switch(event.keyCode) {
// ...
// 不同的按键可以做不同的事情
// 不同的浏览器的keycode不同
// 更多详细信息:
// ...
}
});

网页上的“上一页，下一页”JS代码怎么写？
需要准备的材料分别有：电脑、html编辑器、浏览器。
1、首先，打开html编辑器，新建html文件，例如：index.html。
2、在index.html中的script标签，输入js代码：
var a = parseInt(location.href.split('?')[1].split('=')[1]);
$('body').append('a href="index?page=' + (a - 1) + '"上一页/a');
$('body').append('a href="index?page=' + (a + 1) + '"下一页/a');
3、浏览器运行index.html?page=5页面，此时js会生成出上一页和下一页及其链接。
js中网页前进和后退的代码
前进: history.forward();=history.go(1);\x0d\x0a后退: history.back();=history.go(-1); \x0d\x0a注意事项：前进后退按钮是需要在特定环境下才有效果的，即你需要从另一个页面进入到这个页面后，点击这个后退按钮才有后退的效果，否则是没有的。\x0d\x0a【拓展资料】\x0d\x0ajavascript中的后退和刷新；\x0d\x0a\x0d\x0a\x0d\x0a\x0d\x0a\x0d\x0a 后退+刷新在C# Web程序中，如为页面按钮写返回上一页代码\x0d\x0athis.RegisterClientScriptBlock("E", "history.go(-2);");\x0d\x0a其中，history.go(-2)，要写为-2，因在按钮事件触发前，已刷新一次页面，所以应是-2。\x0d\x0aResponse.Write("history.go(-2);");\x0d\x0a此处也要写为“-2”。跟直接写脚本的有所不同。history.back()是会上一页\x0d\x0ai=1\x0d\x0ahistory.go(i)去指定的某页\x0d\x0a如果是history.go(0)那就是刷新这两个属于JS代码，相当于IE的前进、后退功能。\x0d\x0a具体的用处就要看什么时候需要这个就用上。比如用户注册时的验证是后台验证，不符合要求的时候就可以用这个，可以最大限度保证用户少重复输入数据。\x0d\x0a例如：载入页面：\x0d\x0afunction onLoadPage(){\x0d\x0aif(event.srcElement.tagName=="SPAN"){\x0d\x0aoFrame=top.window.middle.frames[2];\x0d\x0aoTxt=event.srcElement.innerText;\x0d\x0aswitch(oTxt){\x0d\x0acase "前 进":\x0d\x0aoFrame.history.go(1);\x0d\x0acase "后 退":\x0d\x0aoFrame.history.back();\x0d\x0acase "刷 新":\x0d\x0aoFrame.location.reload();\x0d\x0a}\x0d\x0a}\x0d\x0a}\x0d\x0a\x0d\x0a打开一个jsp页面,肯定是用客户端脚本进行刷新了。\x0d\x0aJavascript刷新页面的几种方法：\x0d\x0a1 history.go(0)\x0d\x0a2 location.reload()\x0d\x0a3 location=location\x0d\x0a4 location.assign(location)\x0d\x0a5 document.execCommand('Refresh')\x0d\x0a6 window.navigate(location)\x0d\x0a7 location.replace(location)\x0d\x0a8 document.URL=location.href

一小段引起网页顶部空白的代码，求解释，谢
你这段代码嵌套就有问题，不完整，也不符合HTML语法结构，应该改成：
table width="100%"
tr
td height="12" align="left" valign="top" bgcolor="#FFFFFF" /td
/tr
tr
td
script type="text/javascript"
src=""
/script
/td
/tr
table
