@Oleg - 我是jqGrid的新手，我有三个问题。需要紧急帮助。我正在使用jqGrid 3.8，内联编辑模式。
- 我想在弹出无效单元格后保留无效单元格值。
- 我还想将焦点设置回无效单元格。
- 我的jqGrid中有"添加行"和过滤器工具栏功能。我已经使用Oleg的解决方案为过滤器工具栏创建下拉列表（发布在另一个jQuery线程中）。
** -问题：
**我从afterSaveCell调用setSearchSelect，因为我想在每次添加或删除列时在过滤器下拉列表中添加新值。（注意：列是一个文本框）。但是即使我使用
var sgrid = $("#list")[0];
sgrid.triggerToolbar();
请参阅下面的代码来设置工具栏。
<script type="text/javascript">

{id:"4", Name:"Blaise Pascal", Category:"science", Subcategory:"mathematics"}

getUniqueNames = function(columnName) {
var texts = grid.jqGrid('getCol',columnName), uniqueTexts = [],
textsLength = texts.length, text, textsMap = {}, i;
for (i=0;i<textsLength;i++) {
text = texts[i];
if (text !== undefined && textsMap[text] === undefined) {
// to test whether the texts is unique we place it in the map.
textsMap[text] = true;
uniqueTexts.push(text);
}
}
return uniqueTexts;

buildSearchSelect = function(uniqueNames) {
var values=":All";

@Oleg - 关于您建议的解决方案的另一个问题。对不起，我试图自己找到它，但不能。在buildSearchSelect：方法中，如何包含空字符串的过滤器。如上所述，我有一个"添加行"按钮。因此，当用户想要过滤具有空列的行时，我需要一个过滤器值。
仅当搜索工具栏尚不存在时，我的旧答案中setSearchSelect函数的实现才有效。如果工具栏存在，则必须修改jQuery UI自动完成小部件的选择元素或自动完成源的选项。
我扩展了代码。您可以在此处查看新版本的演示。以同样的方式，可以使用内联编辑而不是单元格编辑。
以下是修改后的 JavaScript 代码：
var mydata = [
{id:"1", Name:"Miroslav Klose", Category:"sport", Subcategory:"football"},
{id:"2", Name:"Michael Schumacher", Category:"sport", Subcategory:"formula 1"},
{id:"3", Name:"Albert Einstein", Category:"science", Subcategory:"physics"},
{id:"4", Name:"Blaise Pascal", Category:"science", Subcategory:"mathematics"}
],

getUniqueNames = function(columnName) {
var texts = grid.jqGrid('getCol',columnName), uniqueTexts = [],
textsLength = texts.length, text, textsMap = {}, i;
for (i=0;i<textsLength;i++) {
text = texts[i];
if (text !== undefined && textsMap[text] === undefined) {
// to test whether the texts is unique we place it in the map.
textsMap[text] = true;
uniqueTexts.push(text);
}
}
uniqueTexts.sort();
return uniqueTexts;
},
buildSearchSelect = function(uniqueNames) {
var values=":All";
$.each (uniqueNames, function() {
values += ";" + this + ":" + this;
});
return values;
},
setSearchSelect = function(columnName) {
var $select = $('select#gs_'+columnName), un = getUniqueNames(columnName),
htmlForSelect = '<option value="">All</option>', i, l=un.length, val;
grid.jqGrid('setColProp', columnName,
{
stype: 'select',
searchoptions: {
value:buildSearchSelect(un),
sopt:['eq']
}
}
);
if ($select.length > 0) {
// The searching toolbar already exist. One have to update it manually
for (i=0;i<l;i++) {
val = un[i];
htmlForSelect += '<option value="'+val+'">'+val+'</option>';
}
$select.html(htmlForSelect);
}
},
setAutocomplete = function(columnName) {

grid.jqGrid('setColProp', columnName,
