獲取更新後的數值列表更新值的servlet中的行後檢查複選框

當我嘗試獲取值後更新兩個或更多的行列，並試圖獲得在servlet中，即時通訊只有一個值在servlet中，我必須發送兩個或更多行，或者我們可以說，項目的更新列表，另一個servlet什麼即時嘗試做我必須給她寫PLZ幫我即時通訊新的Servlet和JSP獲取更新後的數值列表更新值的servlet中的行後檢查複選框

，這是我的servlet

也以英語，似乎新標點。請找一個能夠重寫你的問題的人，因爲我無法理解它。並添加更多的上下文：你想做什麼？ –

@JBNizet實際上，在多行中更改多個列的值之後，當我檢查了我的行時，我無法在我的servlet中獲得那些多個更新的值，除了一個頂行之外。因此如何獲取這些列表在我的servlet中更新了值 – henrycharles

1）您應複選框創建不同的名稱 NAME = 「projectCode」例如employeeProjectBO.projectCode中的servlet添加到這個輸入名稱

2）

for(int i=0; i<projectCode.length; i++) { 
request.getParameterValues("checkedProject"+projectCode.getProjectCode); 
… 
}
