[英]<button> Same Button, Multiple Locations, Different Code
我正在JQTouch中編寫一個應用程序,並使用一個大紅色按鈕
<a href="#" class="redButton">Red</a>
我正在使用PHP動態構建具有多個div的JQT頁面。 該應用程序是一個從MySQL獲取數據的服務器管理控制台。 我的想法是我使用While循環為MySQL查詢中返回的每個服務器創建一個div,每個div都有一個刪除服務器按鈕(大紅色按鈕)。 因為整個動態頁面生成的東西,我必須調用dame位代碼。 所以我想知道是否有一種方法可以讓我用按鈕調用onClick函數Red知道按鈕所在的div是調用函數。 在多個div中會有一個調用相同代碼的按鈕,但我必須知道要刪除的服務器。 有什么建議么?
這是完整的源代碼。

將數據屬性添加到“Big Red Button”,如下所示
<a href="#" class="redButton" data-server="serverval">Red</a>
並從您的處理代碼中檢索數據值,如下所示
var server = $(this).attr('data-server');
然后你可以做你的條件邏輯。
DevZer0的答案可能就是你想要的,但另一種方法是將類添加到包含的div中
echo '<div id="'.$friendlyName_noSpaces2.'" class="server">';
然后你可以在你的回調中做到這一點
var server = $(this).closest(".server").attr("id");
獲取包含div的id。
