jqgrid添加行并将数据发送到webservice以进行插入

Question

我已经能够使用jQuery/Ajax从Web服务中将数据从我的数据库中提取到jQGrid中.现在我想将添加/编辑的数据发送回Web服务.我通过使用PHP和editurl:命令看到了一些例子.这也适用于Web服务(就像我最初下载数据一样)？

我已多次查看这些例子了.我甚至发现了另一个类似于我所问的问题,我无法找到任何关于如何做我需要的实例.有存在吗？

:更新:

jQuery(document).ready(function () {
    jQuery("#list").jqGrid({
        datatype: processrequest,
        mtype: 'POST',
        jsonReader: {
            root: "ListExercise", //arry containing actual data  
            page: "Page", //current page  
            total: "Total", //total pages for the query  
            records: "Records", //total number of records  
            repeatitems: false,
            id: "ID" //index of the column with the PK in it   
        },
        colNames: ['Id', 'Exercise'],
        colModel: [
      { name: 'exercise_id', index: 'exercise_id',editable:false },
      { name: 'exercise_value', index: 'exercise_value',editable:true }
      ],
        caption: 'MyFitnessApplication',
        pager: '#pager',
        rowNum: 10,
        rowList: [10, 20, 30],
        sortorder: "desc",
        viewrecords: true,
        height: '250px',
        loadonce: true,
        editurl: "../webService/exercise_ws.asmx/insertRecord"      
    }).navGrid('#pager', { edit: true, add: true, del: false });
});

如您所见,我添加了editurl标记.这似乎打电话给我的网络服务.现在我想念如何将实际参数传递给webservice.我错过了什么,感谢帮助!

首先,您可以更改用于添加/编辑的一些默认选项:

jQuery.extend(jQuery.jgrid.edit, {
    ajaxEditOptions: { contentType: "application/json" },
    recreateForm: true,
    serializeEditData: function (postData) {
        if (postData.exercise_value === undefined) { postData.exercise_value = null; }
        return JSON.stringify(postData);
    }
});

(http://www.json.org/js.html中JSON.stringify定义的函数在哪里).然后,将发送到服务器的数据将进行JSON编码.几乎相同的设置可用于删除

jQuery.extend(jQuery.jgrid.del, {
    ajaxDelOptions: { contentType: "application/json" },
    serializeDelData: function (postData) {
        if (postData.exercise_value === undefined) { postData.exercise_value = null; }
        return JSON.stringify(postData);
    }
});

现在你可以定义insertRecord如下

[WebMethod, ScriptMethod(ResponseFormat = ResponseFormat.Json)]
public int ModifyData (string exercise_value, string oper, string id)
{
    if (String.Compare (id, "_empty", StringComparison.Ordinal) == 0 ||
        String.Compare (oper, "add", StringComparison.Ordinal) == 0) {

        // TODO: add new item with the exercise_value and return new id
        //       as the method result
    }
    else if (String.Compare (oper, "edit", StringComparison.Ordinal) == 0) {
        // TODO: modify the data identified by the id
    }
    else if (String.Compare (oper, "del", StringComparison.Ordinal) == 0) {
        // TODO: delete the data identified by the id
    }
}

你没有写出哪种类型有exercise_id:整数或字符串.如果使用字符串ID,则应稍微更改上面的代码.
