对象变量转换成JSON字符串asp.net页面的方法 [英] converting object variable to json string for asp.net page method
问题描述
这可能是一个非常简单的任务来执行,但我承担的风险要问无妨。
This is probably a very simple task to perform but I'm taking the risk to ask anyway.
我有一个对象变量,看起来像这样:
I have an object variable that looks like this:
var MyObj = {"Param1": "Default",
"Param2": "test",
"Param3": 3 };
我使用ASP.net,我期待这个对象传递给通过jQuery一个页面的方法。
I'm using ASP.net and I'm looking to pass this object to a page method via jquery.
到目前为止,我有这个JavaScript code:
So far, I have this javascript code:
function LoadObject () {
var TheObject = MyObj.toString();
$.ajax({
type: "POST",
url: "../Pages/TestPage.aspx/GetCount",
data: TheObject,
contentType: "application/json; charset=utf-8",
dataType: "json",
success: successFn,
error: errorFn
});
};
我有一个页面的方法在cs文件设置和我把一个断点,但它永远不会出现;什么也没有发生。
I have a page method set up in the .cs file and I put a breakpoint in it but it never gets there; nothing happens.
请让我知道什么样的变化我需要得到这个工作。
谢谢你。
Please let me know what changes I need to make to get this to work. Thanks.
推荐答案
您需要序列TheObject成JSON字符串,并确保利用getCount方法接受具有相同签名作为TheObject的对象。
You need to serialize TheObject into a JSON string, and ensure that the GetCount method accepts an object with the same signature as TheObject.
我用jQuery.JSON库要做到这一点,使我的语法就变成了:
I use the jQuery.JSON library to do this so that my syntax becomes:
data: "{ methodParameterName: " + $.toJSON(TheObject) + " }"
我用这个库的,但你可以acheive同样的事情用类似的方式的任何其他文库
I use this library, but you can acheive the same thing with any other library in a similar manner
