我有这段代码片段(虽然不完整,但忽略了结尾脚本标签)::
<script type="text/javascript">
function gotoa(){
var h = $.get("http://localhost:8080/2_8_2012/jsp/GetJson.jsp", function(result) {
});
alert(result);
var myVar= h;
var storedata={
identifier:"ID",
label:"name",
items: myVar
};
var store = new dojo.data.ItemFileWriteStore({data: storedata});
GetJson.jsp的代码是::
<%@ page language="java" contentType="text/html; charset=ISO-8859-1"
pageEncoding="ISO-8859-1"%>
<%@ page import="MyPackage.PopulateTextbox" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
<title>Insert title here</title>
<%
String temp1;
PopulateTextbox obj = new PopulateTextbox();
temp1 = obj.method();
%>
<%=temp1 %>
</head>
<body>
</body>
</html>
我有一个j查询get方法。我传入的URL返回一个Json数组字符串。输出URL ::
[{"ID":1,"Names":"Shantanu","Email":"shantanu.tomar@gmail.com"},{"ID":2,"Names":"Mayur","Email":"mayur.sharma@gmail.com"},{"ID":3,"Names":"Rohit"},{"ID":4,"Names":"Jasdeep"},{"ID":5,"Names":"Rakesh","Email":"rakesh.shukla@gmail.com"},{"ID":6,"Names":"Divyanshu"},{"ID":8,"Names":"hello"},{"ID":9,"Names":"fine"},{"ID":10,"Names":"shivani"}]
现在我希望这个输出用于我的数据网格,即我希望var myVar应该获得此值,然后它将传递给dojo.data.ItemFileWriteStore。我无法这样做。请帮忙 ?谢谢。

$.get()
函数是使用$.ajax()
函数进行AJAX调用的简写 - 而且,众所周知,AJAX中的第一个A代表异步。如果要使用AJAX调用的响应来执行代码,则需要将该代码放在传递给$.get()
的回调函数中。
它可能看起来像这样(虽然没有完整的代码,我不能肯定地说:
function gotoa() {
var store;
var h = $.get("http://localhost:8080/2_8_2012/jsp/GetJson.jsp", function(result) {
var myVar = result;
var storedata={
identifier:"ID",
label:"name",
items: myVar
};
store = new dojo.data.ItemFileWriteStore({data: storedata});
// do whatever with store here, if necessary
});
}

修改你的脚本标签:
<script type="text/javascript">
function gotoa(){
$.get("http://localhost:8080/2_8_2012/jsp/GetJson.jsp", function(result) {
var storedata={
identifier:"ID",
label:"name",
items: result
};
var store = new dojo.data.ItemFileWriteStore({data: storedata});
});
}
</script>
GetJson.jsp的代码是:
<%@page contentType="application/json" %>
<%@page import="MyPackage.PopulateTextbox" %>
<%
String temp1;
PopulateTextbox obj = new PopulateTextbox();
temp1 = obj.method();
%>
<%=temp1 %>
现在致电gotoa()
它将初始化ajax调用并在回调函数中获取响应
