我正在尝试使用DropDown列加载gjqxGrid，我尝试使用jsfiddle中的示例json：here，它运行正常。但是当我尝试在我的项目文件中使用相同的代码时，DropDown列是空的，我检查了数据格式，没关系。 以下是项目文件
中的代码 var source_app =
{
datatype: "json",
datafields:[
{ name: 'id' },
{ name: 'name' },
{ name: 'count' },
{ name: 'drop'},
{ name: 'drops'}
],
url: "settings/scenario_count2.php",
cache:false,
updaterow: function (rowid, rowdata, commit) {
var data = "update=true&" + $.param(rowdata);
$.ajax({
dataType: 'json',
url: 'settings/scenario_count2.php',
cache: false,
data: data,
success: function (data, status, xhr) {
// update command is executed.
commit(true);
},
/*
error: function(jqXHR, textStatus, errorThrown)
{
commit(false);
}*/
});
}
};
var dataAdapter_app = new $.jqx.dataAdapter(source_app);
dataAdapter_app.dataBind();
//下面是我的Jqx网格初始化代码 //方法1
$("#scenario_grid2").jqxGrid(
{
width: 520,
height: 253,
source: dataAdapter_app,
editable: true,
theme: theme,
selectionmode: 'multiplecellsadvanced',
columns: [
{ text: 'Id', hidden: true, editable:false, columntype: 'textbox', datafield: 'id'},
{ text: 'Name', columntype: 'textbox', datafield: 'name', width: 140 },
/*{ text: 'Drop', columntype: 'NumberInput', datafield: 'drop', width: 60 }, */
{ text: 'Drop',
datafield: 'drop', width: 160, columntype: "dropdownlist",
initeditor: function (row, cellvalue, editor) {
editor.jqxDropDownList ({source: dataAdapter_app.records[row].drops });
}},
drop column具有下拉列表中需要pe的值数组。如果我替换数据字段＆＃39; drop＆＃39;使用＆＃39; drop＆＃39;，然后我在列中得到逗号分隔值，这意味着数组数据在那里但是没有创建下拉列表。
如果我在网格初始化之前创建了下拉适配器 //方法2
var dropdownListStateAdapter3 = new $.jqx.dataAdapter(dropDownListStateSource3, { autoBind: true, async: false });
并使用如下：
{ text: 'State', columntype: 'dropdownlist', datafield: 'revision_state', width: 55,
initeditor: function (row, cellvalue, editor) {
editor.jqxDropDownList({ displayMember: 'name', source: dropdownListStateAdapter3 });
然后我得到了下拉，但我想要动态下拉，因为每行都有不同的下拉值集。请告诉我如何使用方法1填充下拉列表。
感谢。

aynch：false和autobind：true需要添加到dataAdapter函数中。
var dataAdapter_app = new $.jqx.dataAdapter(source_app,{
loadComplete: function (record) {
console.log(record);
datarecords = JSON.parse(JSON.stringify(record));
},
async:false,
autoBind:true
});

这是我的解决方案
var merchantItems = [
{ name: 'ID', type: 'string' },
{ name: 'NAME', type: 'string' }
]
jQuery(document).ready(function ($) {
$.ajax({
url: "/Parameter/GetMerchantList",
type: "POST",
success: function (e) {
for (var i = 0; i < e.length; i++) {
if (e[i].NAME.trim() == "")
continue;
var mitem = {};
mitem.ID = e[i].ID;
mitem.NAME = e[i].NAME;
merchantItems.push(mitem);
}
merchantItems.splice(0,2);
