我想通過一個php數組到JavaScript函數FindCheckBoxes(Test)使用onClick功能。但是這段代碼似乎不起作用。它看起來像JSON_ENCODING不起作用。傳遞PHP數組到JavaScript函數不工作
如何將我的$ array變量傳遞給JavaScript函數。我搜索了互聯網，但無法使用它。也就是說，警報不會吐出任何東西（空白）。我想「$陣」參數是有 這裏是我的代碼：

你的代碼太長了。減少到最基本的必需品！ – 2013-03-06 17:54:19
那麼，「但這段代碼似乎不起作用」是什麼意思？你期望發生什麼，實際發生了什麼？你在錯誤控制檯中看到JS錯誤嗎？你的'警報（測試）'吐出了什麼？你期望它吐出什麼？ – Steve 2013-03-06 17:57:31
我很抱歉，我現在編輯它。請看看 – user2127569 2013-03-06 18:00:35
