增強(qiáng)網(wǎng)站用戶(hù)體驗(yàn)的幾種JS分頁(yè)代碼

網(wǎng)頁(yè)設(shè)計(jì)中，要考慮的方面很多，當(dāng)然，大體來(lái)說(shuō)就是兩類(lèi)：代碼+UI，簡(jiǎn)潔的代碼加上美觀的UI，是一個(gè)網(wǎng)站理想的選擇，一個(gè)網(wǎng)站設(shè)計(jì)成功與否，很多時(shí)候要從細(xì)節(jié)入手，關(guān)注細(xì)節(jié)，才能關(guān)注用戶(hù)體驗(yàn)，用戶(hù)體驗(yàn)的友好，才能說(shuō)明網(wǎng)站的設(shè)計(jì)是成功的，下面分享7種JS腳本分頁(yè)代碼，讓細(xì)節(jié)到從內(nèi)容頁(yè)面的分頁(yè)上來(lái)，高手可以飄過(guò)，這是寫(xiě)給不懂JS的朋友看的。

7種分頁(yè)腳本定義

----------------------

pg.argName = 'p'; //定義參數(shù)名(可選,缺省為page)
pg.printHtml(); //顯示頁(yè)數(shù)

Supported in Internet Explorer, Mozilla Firefox

以上是定義，下面才是真正的調(diào)用。

document.write(' Show Times: ' + pg.showTimes + ', Mood Default');
pg.printHtml();
document.write(' Show Times: ' + pg.showTimes + ', Mood 0');
pg.printHtml(0);
document.write(' Show Times: ' + pg.showTimes + ', Mood 1');
pg.printHtml(1);
document.write(' Show Times: ' + pg.showTimes + ', Mood 2');
pg.printHtml(2);
document.write(' Show Times: ' + pg.showTimes + ', Mood 3 (only IE)');
pg.printHtml(3);
document.write(' Show Times: ' + pg.showTimes + ', Mood 4');
pg.printHtml(4);
document.write(' Show Times: ' + pg.showTimes + ', Mood 5');
pg.printHtml(5);
//-->
</script>

當(dāng)然這是原始的，沒(méi)定義過(guò)頁(yè)面字體的版本，在實(shí)際使用時(shí)，可以根據(jù)自己網(wǎng)站的主題通過(guò)CSS定義頁(yè)面的字體，邊距屬性，使它看起來(lái)更美觀，更適合你的網(wǎng)站。
