在免费jqGrid中添加/编辑/删除行

Question

我正在使用免费的jqGrid 4.12.1。 我想在网格中添加，编辑和删除行，并希望为每个操作进行服务器端调用。 我添加了如下的editurl和'actions'格式化程序，

 {
  name: "actions",
  width: 100,
  formatter: "actions",
  formatoptions: {
      keys: true,
      editOptions: {},
      addOptions: {},
      delOptions: {}
  }       
  }

我在下面添加“ inlineNav”，

$("#itemList").jqGrid('inlineNav',"#itemListPager", 
         {
            edit: true,
            add: true,
            del: true,
            search: true,
            searchtext: "Search",
            addtext: "Add",
            edittext: "Edit",
            deltext: "Delete"
        },
        {  
            closeOnEscape: true, //Closes the popup on pressing escape key
            reloadAfterSubmit: true,
            drag: true,
            url: "${pageContext.request.contextPath}/billing/saveItem",
            errorfunc: function (rowId, resp) {
                alert(resp);
            },
            afterSubmit: function (response, postdata) {
                if (response.responseText == "") {

                    $(this).jqGrid('setGridParam', { datatype: 'json' }).trigger('reloadGrid'); //Reloads the grid after edit
                    return [true, '']
                }
                else {
                    $(this).jqGrid('setGridParam', { datatype: 'json' }).trigger('reloadGrid'); //Reloads the grid after edit
                    return [false, response.responseText]//Captures and displays the response text on th Edit window
                }
            },
            editData: {
                EmpId: function () {
                    var sel_id = $('#itemList').jqGrid('getGridParam', 'selrow');
                    var value = $('#itemList').jqGrid('getCell', sel_id, '_id');
                    return value;
                }
            }
        },
        {
            closeAfterAdd: true, //Closes the add window after add
            url: "${pageContext.request.contextPath}/billing/saveItem",
            afterSubmit: function (response, postdata) {
                if (response.responseText == "") {

                    $(this).jqGrid('setGridParam', { datatype: 'json' }).trigger('reloadGrid')//Reloads the grid after Add
                    return [true, '']
                }
                else {
                    $(this).jqGrid('setGridParam', { datatype: 'json' }).trigger('reloadGrid')//Reloads the grid after Add
                    return [false, response.responseText]
                }
            }
        },
        {   //DELETE
            closeOnEscape: true,
            closeAfterDelete: true,
            reloadAfterSubmit: true,              
            url: "${pageContext.request.contextPath}/billing/saveItem",
            drag: true,
            afterSubmit: function (response, postdata) {
                if (response.responseText == "") {

                    $("#itemList").trigger("reloadGrid", [{ current: true}]);
                    return [false, response.responseText]
                }
                else {
                    $(this).jqGrid('setGridParam', { datatype: 'json' }).trigger('reloadGrid');
                    return [true, response.responseText]
                }
            },
            delData: {
                EmpId: function () {
                    var sel_id = $('#itemList').jqGrid('getGridParam', 'selrow');
                    var value = $('#itemList').jqGrid('getCell', sel_id, '_id');
                    return value;
                }
            }
        },
        {//SEARCH
            closeOnEscape: true
        }       
        );

上面添加的'inlineNav'无效，因为在添加新行或删除现有行时不会进行服务器端调用。 仅在编辑的情况下才进行服务器端调用，并且该调用也不会通过上面的“ inlineNav”代码发生。 因为即使我删除了“ inlineNav”代码，服务器端调用仍然是对“ editurl”进行的。 因此，我该如何在添加/编辑/删除行上进行服务器端调用，以及如何将参数传递给这些调用。 如果有人能指出我在某处的工作示例，我将不胜感激。 谢谢

我删除了“动作”格式化程序，并修改了代码，使其看起来如下所示，

样本json dada是这样的，

[

{"itemDetailId":2,"itemId":2,"itemType":"Medicine","itemCode":"Benadryl","itemDesc":"Benadryl","batchNumber":"batch1","expiryDate":"18/02/2017","unit":"ml","subUnit":"ml","availableQuantity":60.0,"quantityPerUnit":120.0,"price":90.0}
]

现在，分别在编辑和添加行时调用在editparameters和saveparameters中指定的url。 请建议以上方法是否是一种好的方法。 同样，我们如何在将编辑或保存数据发布到服务器之前设置请求标头。 而且我找不到类似于deleteparameters的东西，类似于editparameters和saveparameters，所以我可以使用delete特定参数。

更新2：-

在使用以下代码在添加/编辑行上调用服务器端代码之前，我可以成功设置一个请求标头，

 $.ajaxSetup({
            beforeSend: function (jqXHR, settings) {                     
               jqXHR.setRequestHeader("X-CSRF-TOKEN", $("input[name='_csrf']").val());
          }});

Answer 1

您应该检查inlineNav的选项，以发现您使用了绝对错误的选项：

jQuery("#grid_id").jqGrid('inlineNav', pagerid, parameters);

parameters的形式

{ 
    edit: true,
    editicon: "ui-icon-pencil",
    add: true,
    addicon: "ui-icon-plus",
    save: true,
    saveicon: "ui-icon-disk",
    cancel: true,
    cancelicon: "ui-icon-cancel",
    addParams: {useFormatter : false},
    editParams: {}
}

您使用另一种方法navGrid的选项

jQuery("#grid_id").jqGrid('navGrid', '#gridpager', {parameters},
    prmEdit, prmAdd, prmDel, prmSearch, prmView);

允许使用表单编辑 。

你写你想要同时使用formater: "actions"和 inlineNav . Thus you would have to provide some options of inline editing twice.

You will have to provide inlineNav的addParams and editParams properties of and the corresponding options of formatter and the corresponding options of ：“ actions”`（请参见此处 ）。 为了使代码更具可读性和简单性，免费的jqGrid提供了另一种形式的编辑选项。

您可以指定所有内嵌编辑选项里面的inlineEditing jqGrid的的选择，额外的特定选项inlineNav方法（如果需要）在navOptions或inlineNavOptions ，在删除操作的选项formDeleting等。 此外， reloadGrid还具有fromServer: true选项，以恢复您使用的datatype （ "json" ， "jsonp" ， "xml" ，...）的原始值。 您可以使用表单编辑或formDeleting reloadGridOptions: { fromServer: true }选项强制从服务器重新加载。

而且，您现有的代码包含很多带有_id和EmpId可疑部分。 我强烈建议您提供用于填充网格的JSON输入数据格式示例。 如果要使用EmpId作为rowid的名称，为什么要改用_id ？ 代码片段像

EmpId: function () {
    var sel_id = $('#itemList').jqGrid('getGridParam', 'selrow');
    var value = $('#itemList').jqGrid('getCell', sel_id, '_id');
    return value;
}

显示当前的rowid似乎是错误的，并且_id列包含正确的信息，您需要以EmpId的名称作为rowid。

例如，您可以使用prmNames: { id: "EmpId"}并将key: true添加到_id列。 该物业key: true列_id会通知的jqGrid使用的值从列_id为ROWID和prmNames: { id: "EmpId"}将重命名默认的id在编辑使用属性和Delete EmpId 。 因此，jqGrid将在“删除”和“编辑”操作期间将带有_id列中值的EmpId参数自动发送到服务器。

也许您也可以从网格中删除不需要的列_id （至少在隐藏该列的情况下），但是我需要查看jqGrid的输入数据以说出可以使用的jqGrid的确切选项。

我确信您可以使用免费的jqGrid选项实质上减少现有代码并使其更具可读性，但是您必须仔细检查现有代码。 我建议您首先使用正确的rowid并消除所使用的所有隐藏列。 免费的jqGrid提供additionalProperties功能，结构非常接近的结构colModel ，但输入相应的数据属性将被保存在本地数据仅供参考，不放在桌上的DOM。 我可以更清楚地解释一下，如果您要发布现有的colModel ， jsonReader和从服务器返回的JSON响应示例（1-2行带有伪数据的数据就足够了）。
