網頁中的「下一頁」怎麼實現

網頁中的「下一頁」實現的方法。

如下參考：

1.首先，打開HTML編輯器並創建一個新的HTML文件，如index.html。

2.在index.html中的script標籤，輸入js代碼：

varnow=parseInt(location.href.split(‘?’)[1].split(‘=’)[1]);

$(‘body’).append(‘a href=”index?page=’+ (now-1)+'”上一頁/a’);

$(‘body’).append(‘a href=”index?page=’+ (now+1)+'”下一頁/a’);

3.在chrome瀏覽器中運行index.html頁面，上一頁和下一頁的a標記將用js列印。

求鍵盤的所有按鍵對應的JS函數~~~！！！！或者提供網頁鍵盤源代碼！！

$(window).keydown(function(event){

switch(event.keyCode) {

// …

// 不同的按鍵可以做不同的事情

// 不同的瀏覽器的keycode不同

// 更多詳細信息:

// …

}

});

網頁上的「上一頁，下一頁」JS代碼怎麼寫？

需要準備的材料分別有：電腦、html編輯器、瀏覽器。

1、首先，打開html編輯器，新建html文件，例如：index.html。

2、在index.html中的script標籤，輸入js代碼：

var a = parseInt(location.href.split(‘?’)[1].split(‘=’)[1]);

$(‘body’).append(‘a href=”index?page=’ + (a – 1) + ‘”上一頁/a’);

$(‘body’).append(‘a href=”index?page=’ + (a + 1) + ‘”下一頁/a’);

3、瀏覽器運行index.html?page=5頁面，此時js會生成出上一頁和下一頁及其鏈接。

js中網頁前進和後退的代碼

前進: history.forward();=history.go(1);\x0d\x0a後退: history.back();=history.go(-1); \x0d\x0a注意事項：前進後退按鈕是需要在特定環境下才有效果的，即你需要從另一個頁面進入到這個頁面後，點擊這個後退按鈕才有後退的效果，否則是沒有的。\x0d\x0a【拓展資料】\x0d\x0ajavascript中的後退和刷新；\x0d\x0a\x0d\x0a\x0d\x0a\x0d\x0a\x0d\x0a 後退+刷新在C# Web程序中，如為頁面按鈕寫返回上一頁代碼\x0d\x0athis.RegisterClientScriptBlock(“E”, “history.go(-2);”);\x0d\x0a其中，history.go(-2)，要寫為-2，因在按鈕事件觸發前，已刷新一次頁面，所以應是-2。\x0d\x0aResponse.Write(“history.go(-2);”);\x0d\x0a此處也要寫為「-2」。跟直接寫腳本的有所不同。history.back()是會上一頁\x0d\x0ai=1\x0d\x0ahistory.go(i)去指定的某頁\x0d\x0a如果是history.go(0)那就是刷新這兩個屬於JS代碼，相當於IE的前進、後退功能。\x0d\x0a具體的用處就要看什麼時候需要這個就用上。比如用戶註冊時的驗證是後台驗證，不符合要求的時候就可以用這個，可以最大限度保證用戶少重複輸入數據。\x0d\x0a例如：載入頁面：\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 進”:\x0d\x0aoFrame.history.go(1);\x0d\x0acase “後 退”:\x0d\x0aoFrame.history.back();\x0d\x0acase “刷 新”:\x0d\x0aoFrame.location.reload();\x0d\x0a}\x0d\x0a}\x0d\x0a}\x0d\x0a\x0d\x0a打開一個jsp頁面,肯定是用客戶端腳本進行刷新了。\x0d\x0aJavascript刷新頁面的幾種方法：\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

一小段引起網頁頂部空白的代碼，求解釋，謝

你這段代碼嵌套就有問題，不完整，也不符合HTML語法結構，應該改成：

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
