[TOC] ## 語法 ``` jQuery.getScript( url [, success(script, textStatus, jqXHR) ] ) ``` 相當于 ``` $.ajax({ url: url, dataType: "script", success: success }); ``` ### 緩存響應 全局的使用 `$.ajaxSetup()`設置cache(緩存)屬性覆蓋該功能 ``` $.ajaxSetup({ cache: true }); ``` ## 示例 ### 導入腳本并執行 ``` $.getScript("ajax/test.js", function(data, textStatus, jqxhr) { console.log(data); //data returned console.log(textStatus); //success console.log(jqxhr.status); //200 console.log('Load was performed.'); }); ``` ### 定義了一個 $.cachedScript() 方法可以獲取緩存的腳本 ``` jQuery.cachedScript = function(url, options) { // allow user to set any option except for dataType, cache, and url options = $.extend(options || {}, { dataType: "script", cache: true, url: url }); // Use $.ajax() since it is more flexible than $.getScript // Return the jqXHR object so we can chain callbacks return jQuery.ajax(options); }; // Usage $.cachedScript("ajax/test.js").done(function(script, textStatus) { console.log( textStatus ); }); ```
