轉載自??jQuery?Raty星級評分插件使用方法?

使用jQuery Raty，可以很方便的在頁面上嵌入一個評分組件，如下所示：

????

使用方法很簡單，首先從https://github.com/wbotelhos/raty下載raty的源代碼（依賴于jquery）

然后在頁面中引入相應的js文件、css文件、圖片資源，在需要添加評分組件的元素上（比如span標簽）添加下面的jquery代碼即可：

$('span').raty();

以上為jQuery Raty的缺省使用方法，此外，該組件還支持豐富的傳入參數和回調函數，例如：

設置jQuery Raty的初始評分：

????

評分回調函數

????

如果需要根據后臺動態設置初始評分，可以使用回調函數實現。例如使用div中的data-attribute屬性：

<div data-score="1"></div>

$('div').raty({score: function() {return $(this).attr('data-score');} });

還可以改變星星的個數：

?????????

$('div').raty({ number: 10 });

只讀模式：

????

$('div').raty({ readOnly: true, score: 3 });

點擊事件：

????

$('div').raty({click: function(score, evt) {alert('ID: ' + this.id + "\nscore: " + score + "\nevent: " + evt);} });

路徑：

變更圖標保存的位置，所有圖標需要位于同一目錄下，路徑結尾的/不添加也可以

<div data-path="assets/images"></div>

$('div').raty({path: function() {return this.getAttribute('data-path');} });

取消評分：

?????

$('div').raty({ cancel: true });

全局改變設置：

你可以全局更改上述提到的所有設置 $.fn.raty.defaults.OPTION = VALUE;. 該語句必須添加在插件綁定之前。

$.fn.raty.defaults.path = assets; $.fn.raty.defaults.cancel = true;

參數列表：

cancel : false // Creates a cancel button to cancel the rating. cancelClass : 'raty-cancel' // Name of cancel's class. cancelHint : 'Cancel this rating!' // The cancel's button hint. cancelOff : 'cancel-off.png' // Icon used on active cancel. cancelOn : 'cancel-on.png' // Icon used inactive cancel. cancelPlace : 'left' // Cancel's button position. click : undefined // Callback executed on rating click. half : false // Enables half star selection. halfShow : true // Enables half star display. hints : ['bad', 'poor', 'regular', 'good', 'gorgeous'] // Hints used on each star. iconRange : undefined // Object list with position and icon on and off to do a mixed icons. mouseout : undefined // Callback executed on mouseout. mouseover : undefined // Callback executed on mouseover. noRatedMsg : 'Not rated yet!' // Hint for no rated elements when it's readOnly. number : 5 // Number of stars that will be presented. numberMax : 20 // Max of star the option number can creates. path : undefined // A global locate where the icon will be looked. precision : false // Enables the selection of a precision score. readOnly : false // Turns the rating read-only. round : { down: .25, full: .6, up: .76 } // Included values attributes to do the score round math. score : undefined // Initial rating. scoreName : 'score' // Name of the hidden field that holds the score value. single : false // Enables just a single star selection. space : true // Puts space between the icons. starHalf : 'star-half.png' // The name of the half star image. starOff : 'star-off.png' // Name of the star image off. starOn : 'star-on.png' // Name of the star image on. target : undefined // Element selector where the score will be displayed. targetFormat: '{score}' // Template to interpolate the score in. targetKeep : false // If the last rating value will be keeped after mouseout. targetScore : undefined // Element selector where the score will be filled, instead of creating a new hidden field (scoreName option). targetText : '' // Default text setted on target. targetType : 'hint' // Option to choose if target will receive hint o 'score' type. starType : 'img' // Element used to represent a star.

回調函數列表：

$('div').raty('score'); // Get the current score.$('div').raty('score', number); // Set the score.$('div').raty('click', number); // Click on some star.$('div').raty('readOnly', boolean); // Change the read-only state.$('div').raty('cancel', boolean); // Cancel the rating. The last param force the click callback.$('div').raty('reload'); // Reload the rating with the current configuration.$('div').raty('set', { option: value }); // Reset the rating with new configurations.$('div').raty('destroy'); // Destroy the bind and give you the raw element.$('div').raty('move', number); // Move the mouse to the given score point position.
