Java的批量添加數據，多個字段同時添加多條數據，我不知道你遇到過沒有。今天我們就以一個具體的實例來說一下Java的批量添加數據，面向的是Oracle數據庫。
前台頁面：

複製代碼代碼如下:<span style="font-family:KaiTi_GB2312;font-size:14px;">$(function(){
loadCheck();
});</span>
它就是如下代碼的縮寫：
複製代碼代碼如下:<span style="font-family:KaiTi_GB2312;font-size:14px;"> $(document).ready(function(){
loadCheck();
});</span>
其實這個代碼和下面的代碼是一個意思：
複製代碼代碼如下:<span style="font-family:KaiTi_GB2312;font-size:14px;">window.onload=function(){
loadCheck();
}</span>
這樣就不用在body的onload事件裡面調用，只需要在js程序段裡面編寫就可以了。雖然下面的代碼可以和上面兩個互換，但他們之間又有不同。首先是執行時間不同，$(document).ready在頁面框架下載完畢後就執行，而window.onload必須在頁面全部加載完畢（包含圖片下載）後才能執行。很明顯前者的執行效率高於後者。再就是執行數量的不同，$(document).ready可以重複寫多個，而且每次執行結果不同；而window.onload儘管可以執行多個，但僅輸出最後一個執行結果，無法完成多個結果的輸出。
以上就是本文的全部內容，希望對大家的學習有所幫助。
