我從會話中得到一個字符串數組,我想從數組中顯示字符串。jsp:如何從會話中獲取價值?
我知道javascript無法直接從會話中獲取數據。有什麼方法可以從會話中獲取數據並將其傳輸到javascrip?
我的代碼如下:
<%@ page language="java" contentType="text/html; charset=ISO-8859-1"
pageEncoding="ISO-8859-1"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<%String[] sele = (String[])session.getAttribute("selections");%>;
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
<meta http-equiv="Expires" content="0">
<meta http-equiv="kiben" content="no-cache">
<title>Check List</title>
<script language="javascript" type="text/JavaScript" src="cookie.js">
</script>
<script text="text/javascript">
{
var selections = //String array form session
for(var v=0;v<selections.length;v++){
fillForm(selections[v]);
}
}
function fillForm(name){
var checkbox= document.createElement("input");
checkbox.type="checkbox";
checkbox.name=name;
checkbox.value=name;
checkbox.id=name;
var label = document.createElement("label");
label.htmlFor="id";
label.appendChild(document.createTextNode(name));
var container = document.getElementById("checklist");
container.appendChild(checkbox);
container.appendChild(label);
container.appendChild(document.createElement("br"));
}
function submitAction(){
addUserName(document.getElementById("checklist"));
var elem = document.getElementById("checklist").elements;
for(i =0;i<elem.length;i++){
elem[i].checked = true;
}
var form = document.getElementById("checklist");
form.submit();
}
</script>
</head>
<body>
<form id="checklist" action="selection">
</form>
<Button type="button" onclick="submitAction()" name="submit">Submit</button>
</body>
</html>
你真的不「通」變量的JavaScript這麼多,因爲它們打印到它。 – developerwjk
