Handsontable Grid-从ASPX网页加载和保存数据 [英] Handsontable Grid - loading and saving data from aspx web page
问题描述
是否可以使用aspx页面背面的c#代码将数据加载到网格或从网格保存数据,还是必须使用Web服务(或PHP)?我尝试过使用JSON.Net映射一个非常简单的结构来编码后端结构的尝试失败了
Is it possible to load and save data to/from a grid using c# code in the back from an aspx page, or does one have to use a web service (or PHP)? I have tried and failed using JSON.Net to map a very simple structure to code a backend structure
是否可以使用JQuery(我猜想是ajax GET
)对后端代码文件(.aspx.cs)中的方法进行调用?我已经尝试过使用该论坛上各种帖子中的代码,但是有关后端代码(c#)的信息很少,而且所有内容似乎都涉及Web服务.任何帮助/建议将不胜感激.
Is it possible to use JQuery (an ajax GET
I presume) to make a call to a method in the backend code file (.aspx.cs)? I have tried using code from various posts on this forum, but there is little information on the backend code (c#), and all seem to refer to web services. Any help/advice would be much appreciated.
以下是关联的JavaScript代码:
Here is the JavaScript code associated:
var handsontable = $container.data('handsontable');
$(document).find('button[name=load]').click(function () {
$.ajax({
url: "Default.aspx/getJSData",
dataType: 'json',
type: 'GET',
//contentType: "application/json; charset=utf-8",
success: function (res) {
handsontable.loadData(res.data);
$console.text('Data loaded');
},
error: function () {
$console.text('Load error');
}
});
});
推荐答案
您仍然需要进行Ajax调用,但不需要进行Web服务(可以).您想要暴露给Ajax调用的函数将[WebMethod]
属性设置为打开,并使用将EnablePageMethods属性设置为true的脚本管理器.
You still need to do an Ajax call but you don't need to do a web service (you can). The function you want exposed to the Ajax call put the [WebMethod]
Attribute on and an use a Script Manager with the EnablePageMethods attribute set to true.
<asp:ScriptManager ID="ScriptManager1" runat="server" EnablePageMethods="True">
</asp:ScriptManager>
访问方法:
[WebMethod]
public static void SomeFunction(string message, string name)
{
}
使用jQuery进行Ajax调用
Ajax call using jQuery
(function($) {
$.ajax({
type: "POST",
url: "test.aspx/SomeFunction",
data: "{message:'Hello World', name: 'Bob'}",
contentType: "application/json; charset=utf-8",
dataType: "json",
success: function (msg) {
alert('success');
}
});
});
