我想在HTML中的輸入=「圖像」上運行javascript menthod。我在我的HTML代碼如下所示：html onclick運行javascript功能不工作
onclick="manageHandlers('Unassign'); document.getElementsByName('manageHandlers')[0].submit(); "
，在我的JavaScript的方法是這樣的：
function manageHandlers(parameter){
alert("It's working: "+parameter);
}
有什麼我做錯了嗎？我昨天可以證明這一點，但今天它沒有做任何事情。
感謝您的關注！
完全的html代碼：

你能告訴我你的HTML代碼？ – Oyeme 2012-01-27 09:34:48
您是否檢查過您的javacript文件是否包含在頁面的頂部。你的瀏覽器中是否有任何javascript錯誤？ – CSharpened 2012-01-27 09:36:31
我正在Liferay門戶中使用jsp，適用於我所做的所有其他頁面。我也做了完全一樣的，但對於這個，它只是沒有運行的功能出於某種原因。在瀏覽器中沒有js錯誤沒有 – Tiwaz89 2012-01-27 09:38:26
