jsp JS删除提示框和整数类型参数传递

JS删除提示框

1.js

function delCust(lkmId) {
    var sure = window.confirm("确定删除此用户么?");
    if(sure) {
        window.location.href = "${pageContext.request.contextPath}/linkman/deleteLinkman?lkmId=" + lkmId;
    }
}

1.jsp

<a href="javascript:delCust('${lkmId}')">删除</a>

<%--
    javascript: -> 作用是告诉a标签的href属性执行脚本代码
    
    js函数传入的参数要用''包围起来!!!

jsp JSP基础2

JSPでクラスをインポートする

Kirby

// プロジェクトフォルダ > Java リソース > src > model > Kirby.java
package model;

public class Kirby {
	private String id;
	private String name;
	public Employee(String id, String name) {
		this.id = id;
		this.name = name;
	}
	public String getId() { return id; }
	public String getName() { return name; }

}

index

// プロジェクトフォルダ > WebContent > index.jsp
<!-- pageディレクティブでクラスも一緒にインポート -->
<%@ page language="java" contentType="text/html; charset=UTF-8"
    pageEncoding="UTF-8" import="model.Kirby" %>
<%
Kirby krb = new Kirby("0001", "GREEN GREENS");
%>
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>SampleJSP</title>
</head>
<body>
<p>IDは<%= krb.getId() %>、名前は<%= krb.getName() %>です</p>
</body>
</html>

jsp 将时间戳值转换为日期时间

formatedDate.jsp

<%@ taglib prefix="fmt" uri="http://java.sun.com/jsp/jstl/fmt" %>
<jsp:useBean id="dateObject" class="java.util.Date" />
<jsp:setProperty name="dateObject" property="time" value="${timeInMilliSeconds}" />
<fmt:formatDate value="${dateObject}" pattern="MMddyyyy HHmm" var="formatedDate" />
Date is: ${formatedDate}
