評分功能常出現在一些商品陳列網站,像這種透過選幾顆星星來做評價,在許多網站都看的到,例如 <a href="http://tw.movie.yahoo.com/" target="_blank">YAHOO! 奇摩電影</a> 就有類似的功能,而這篇就是來介紹如何用 jQuery plugin- jStarbox 來實現這項應用 | ||
|
||
<!--more--> | ||
|
||
##Start | ||
|
||
jStarbox檔案不到6k,算是相檔的輕巧,css樣式也不多,不會有那種讓人不知道如何修改起的煩惱,source code 可以直接去 github 下載回來 | ||
|
||
<a href="https://github.com/sabberworm/jStarbox#getvalue" target="_blank">DOWNLOAD SOURCE</a> | ||
|
||
裡面有兩個資料夾分別是 images 和 css,還有一個 jstarbox.js 檔案,直接載入 css 和 js 檔到專案裡面,當然 jQuery 也不要忘了 | ||
|
||
<link href="css/jstarbox.css" rel="stylesheet"></link> | ||
<script type="text/javascript" src="http://code.jquery.com/jquery-1.8.2.js"></script> | ||
<script src="jstarbox.js"></script> | ||
|
||
接下來是 html 部份 | ||
|
||
<div class="starbox"> | ||
</div> | ||
|
||
沒看錯,只要放個空元素在 html 上即可,並且給他一個 class 名稱方便等下操作,最後是 js 部份 | ||
|
||
$('.starbox').starbox({ | ||
average: 0.5, | ||
changeable: 'once', | ||
autoUpdateAverage: true, | ||
ghosting: true | ||
}); | ||
|
||
這樣就大功告成囉 | ||
|
||
###參數設定 | ||
|
||
以下是一些參數的講解,但有些小弟才疏,也不太懂他的意思就不寫出來誤導大家Orz,有興趣的各位再請去 github 上面看 | ||
|
||
**average**:可以預設一開始顯示幾顆星星,也可以使用小數點,例如0.4,預設值則是0.5 | ||
|
||
**stars**:設定有幾顆星星可以選擇,預設值是5 | ||
|
||
**buttons**:設定星星可以切割成多少區塊可以選擇,假設有5顆星星,buttons設10,每顆星星就可以選擇半顆或整顆 | ||
|
||
**changeable**:設定選擇以後是否還可以改變 | ||
|
||
也有一些方法可以呼叫,例如要得知 User 選了幾顆星星,就可以這樣寫 | ||
|
||
$('.btn').click(function(){ | ||
alert($('.starbox').starbox("getValue")); | ||
}); | ||
|
||
可以把事件寫在某個按鈕裡面,當按下按鈕就秀出值是多少,關鍵在這句 | ||
|
||
$('.starbox').starbox("getValue") | ||
|
||
##小小總結 | ||
|
||
如果用 firebug 看套用效果後的 html 結構,不難發現只是在空元素裡面增加幾個<div>,並且設定背景圖做為星星,所以要修改的話只要改範例裡面的圖,和 css 裡面的樣式即可 | ||
|
||
.starbox .stars .star_holder .star { | ||
background-image: url('../images/5-large.png'); | ||
width: 33px; | ||
height: 33px; | ||
} | ||
|
||
記得如果星星的大小有改變,width和 height 也要跟著調整 | ||
