从jQuery Grid插件向ASP.NET MVC控制器操作传递额外的参数 [英] Passing extra parameters to ASP.NET MVC controller action from jQuery Grid plugin

问题描述

我正在尝试将jQuery Grid插件与ASP.NET MVC一起使用以显示数据. Web上提供的示例似乎表明，控制器操作签名如下所示:

I am trying to use jQuery Grid plugin with ASP.NET MVC to display data. It seems examples provided on the web shows that the controller action signature looks like this:

public ActionResult SomeMethod(string sidx, string sord, int page, int rows) { }

有什么办法可以从页面上的各个输入字段传递额外的参数?

Is there any way I can pass extra parameters from various input fields on the page?

干杯， D.

已添加:我尚未编写任何代码，但客户端代码将类似于:

ADDED: I have not written any code yet but the client side code will be something like:

jQuery(document).ready(function(){ 
      jQuery("#list").jqGrid({
        url:'/Entry/GridData/',
        datatype: 'json',
        mtype: 'POST',
        colNames:['Entry Date','Registration','Registered Name'],
        colModel :[
          {name:'EntryDate', index:'EntryDate', width:40 },
          {name:'Registration', index:'Registration', width:200 },
          {name:'RegisteredName', index:'RegisteredName', width:200 }],
        pager: jQuery('#pager'),
        rowNum:20,
        rowList:[5,10,20,50],
        altRows: true,
        sortable: false,
        viewrecords: true,
        caption: 'My first grid'
      }); 
    });

服务器端代码类似于:

public ActionResult GridData(string sidx, string sord, int page, int rows)
{
    //Some stuff to get data, which needs a couple of extra parameters on top of the ones in the signature
    return Json(dataCollection);
}

在GridData动作中，我需要几个其他参数来获取适当的数据.如何在javascript中指定这些内容，以及如何在控制器操作中获取它们?

In the GridData action I need a couple more parameters to get the appropriate data. How do I specify these in the javascript, and how do I get hold of them in the controller action?

推荐答案

您可以使用postData属性:

$('#list').jqGrid({
    url: '@Url.Action("SomeMethod")',
    datatype: 'json',
    mtype: 'POST'
    postData: { 
        someParam1: $('#someInput1').val(),
        someParam2: $('#someInput2').val() 
    }
    ...
});

，然后在控制器操作中可以添加以下参数:

and in your controller action you could add this parameter:

public ActionResult SomeMethod(string someParam1, string someParam2, string sidx, ...) { }
