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editurl和'actions'格式化程序，如下所示，
{
name: "actions",
width: 100,
formatter: "actions",
formatoptions: {
keys: true,
editOptions: {},
addOptions: {},
delOptions: {}
}
}
我正在添加'inlineNav'，如下所示，
$("#itemList").jqGrid('inlineNav',"#itemListPager",
{
edit: true,
add: true,
del: true,
search: true,
searchtext: "Search",
addtext: "Add",
edittext: "Edit",
deltext: "Delete"
},
{
closeOnEscape: true, //Closes the popup on pressing escape key
reloadAfterSubmit: true,
drag: true,
url: "${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'没有任何效果，因为在添加新行或删除现有行时没有进行服务器端调用。服务器端调用仅在编辑的情况下进行，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'inlineNav'代码，服务器端调用仍然是'editurl'。 那么如何在添加/编辑/删除行时进行服务器端调用，并将参数传递给这些调用。如果有人能指出我在某个地方的工作实例，我将非常感激。谢谢

我删除了'actions'格式化程序并修改了代码，如下所示
<script type="text/javascript">
var dataGrid = $('#itemList');
var firstClick = true;

示例json dada是，
[

{"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，在编辑和添加行时，将调用editparameters和saveparameters中指定的url。 请建议以上方法是否合适。另外，我们如何在编辑之前设置请求标头或将数据保存到服务器。我找不到像editparameters和saveparameters类似的deleteparameters，以便我可以使用删除特定的参数。
更新2： -
我可以使用以下代码在添加/编辑行上调用服务器端代码之前成功设置请求标头，
$.ajaxSetup({
beforeSend: function (jqXHR, settings) {
jqXHR.setRequestHeader("X-CSRF-TOKEN", $("input[name='_csrf']").val());
}});

答案 0 :(得分：3)
您应该检查inlineNav的选项，以找出您使用绝对错误的选项：
jQuery("#grid_id").jqGrid('inlineNav', pagerid, parameters);
其中parameters的格式为
{
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: {}
}
您使用其他方法navGrid
的选项jQuery("#grid_id").jqGrid('navGrid', '#gridpager', {parameters},
prmEdit, prmAdd, prmDel, prmSearch, prmView);
允许使用form editing。
您写道，您希望使用 formater: "actions"和 inlineNav . Thus you would have to provide some options of inline editing twice. I would recommend you to read [the wiki article](https://github.com/free-jqgrid/jqGrid/wiki/New-style-of-usage-options-of-internal-methods). It describes the problems with the usage of form editing using格式化程序：＆＃34;操作＆＃34; and navGrid together. The usage of inline editing have very close problems. You will have to provide addParams and editParams properties of inlineNav and the corresponding options of formatter：＆＃34; actions＆＃34;`（参见here）。为了使代码更具可读性和简单性，jqGrid提供了另一种编辑选项。
您可以在 jqGrid 的inlineEditing选项中指定所有内联编辑选项，在inlineNav或其中navOptions方法的其他特定选项（如果需要） inlineNavOptions，formDeleting中删除操作的选项，等等。此外，reloadGrid可以选择fromServer: true来恢复datatype（"json"，"jsonp"，"xml"，...）的原始值用过的。您可以使用表单编辑的reloadGridOptions: { fromServer: true }选项或formDeleting强制从服务器重新加载。
此外，您现有的代码包含许多包含_id和EmpId的非常可疑的部分。我强烈建议您包含输入JSON数据格式的示例，用于填充网格。如果您想使用EmpId作为rowid的名称，为什么要使用_id呢？代码片段如
EmpId: function () {
var sel_id = $('#itemList').jqGrid('getGridParam', 'selrow');
var value = $('#itemList').jqGrid('getCell', sel_id, '_id');
return value;
}
显示当前rowid似乎有误，_id列包含正确的信息，您需要将其作为名称EmpId下的rowid。
您可以使用prmNames: { id: "EmpId"}并将key: true添加到列_id。列key: true中的属性_id将通知jqGrid使用列_id中的值作为rowid，prmNames: { id: "EmpId"}将重命名默认的id属性编辑并删除到EmpId。因此，jqGrid将自动发送EmpId参数，并在删除和编辑操作期间将_id列中的值发送到服务器。
也可以从网格中删除不需要的列_id（至少如果你隐藏了列），但我需要查看jqGrid的输入数据来说明确切的选项您可以使用的jqGrid。
我确信您可以使用免费的jqGrid选项从根本上减少现有代码并使其更具可读性，但您必须仔细检查现有代码。我建议你从使用正确的rowid开始，并删除你使用的所有隐藏列。自由jqGrid提供additionalProperties功能，其结构非常接近colModel的结构，但输入数据的相应属性将仅保存在本地数据中，而不是放在表的DOM中。如果您发布现有的colModel，jsonReader以及从服务器返回的JSON响应示例（带有虚拟数据的1-2行数据就足够了），我可以更清楚地解释。
