JavaScriptSerializer 用于序列化 JavaScript 函数名称

发布于 2024-09-19 07:16:51 字数 607 浏览 11 评论 0原文

我在项目中使用 Flexigrid 在网格工具栏上添加一个按钮，我可以使用如下代码：

...    
"buttons":[
    {"name":"Modifica","bclass":"edit","onpress":"doCommand"},
    {"name":"Elimina","bclass":"delete","onpress":"doCommand"}
],
...

无论如何，“onpress”属性应包含对 js 回调的引用，因此该字段不应包含在引号内。

我正在使用 JavaScriptSerializer 类（在 System.Web.Script.Serialization 命名空间中）来进行序列化。

我必须如何声明变量才能使 JavaScriptSerializer 像这样序列化？

...    
"buttons":[
    {"name":"Modifica","bclass":"edit","onpress":doCommand},
    {"name":"Elimina","bclass":"delete","onpress":doCommand}
],
...

感谢您的帮助！

I am using Flexigrid in my project to add a button on the grid toolbar I can use code like this:

...    
"buttons":[
    {"name":"Modifica","bclass":"edit","onpress":"doCommand"},
    {"name":"Elimina","bclass":"delete","onpress":"doCommand"}
],
...

Anyway the "onpress" attribute shall contain a reference to a js callback and so this field shall not be enclosed within quotation marks.

I am using the class JavaScriptSerializer (in the System.Web.Script.Serialization namespace) to do the serialization.

How I have to declare the variable to make JavaScriptSerializer serialize like this?

...    
"buttons":[
    {"name":"Modifica","bclass":"edit","onpress":doCommand},
    {"name":"Elimina","bclass":"delete","onpress":doCommand}
],
...

Thanks for helping!

这招怎么样？

var param = new Dictionary<string,string>();

param["onpress"] = "%doCommand%";

return new JavaScriptSerializer().Serialize( param ).Replace( "\"%", "" ).Replace( "%\"", "" );

How about this trick ?

var param = new Dictionary<string,string>();

param["onpress"] = "%doCommand%";

return new JavaScriptSerializer().Serialize( param ).Replace( "\"%", "" ).Replace( "%\"", "" );

据我所知，没有一种使用 .NET 序列化程序执行此操作的本机方法，但您可以在客户端执行以下代码，将 onpress JSON 字符串转换为回调...

var buttons = []; // Your JSON array
for(var i = 0; i < buttons.length; i++) {
  var b = buttons[i];
  b.onpress = window[b.onpress];
}

To the best of my knowledge, there is not a native way to do this with the .NET serializer, but you could execute the following code on the client-side to turn the onpress JSON string into a callback...

var buttons = []; // Your JSON array
for(var i = 0; i < buttons.length; i++) {
  var b = buttons[i];
  b.onpress = window[b.onpress];
}

JavaScriptSerializer旨在序列化为JSON，而JSON不能表示函数；它也不能引用先前定义的变量。所以我不相信这是可能的。

您可以将函数名称存储为字符串

...    
"buttons":[
    {"name":"Modifica","bclass":"edit","onpress":"doCommand"},
    {"name":"Elimina","bclass":"delete","onpress":"doCommand"}
],
...

You can store the function name as a string

...    
"buttons":[
    {"name":"Modifica","bclass":"edit","onpress":"doCommand"},
    {"name":"Elimina","bclass":"delete","onpress":"doCommand"}
],
...
