我是先将下拉选项的值通过datagrid的url查出来了，在每一行的row中
//项目结果选项卡的列表
$('#project_table').datagrid({
width : '100%',
height: '378',
url : 'getSeparationProjectInf',
//title : '待分发条码列表',
striped : true,
nowrap : true,
rownumbers : true,
singleSelect : true,

scrollbarSize:0,
fitColumns : true,
checkOnSelect : true,
onClickRow: function (rowIndex, rowData) {
//$(this).datagrid('unselectRow', rowIndex);
var _this = this;
if (editIndex != undefined && editIndex != rowIndex) {
//结束行编辑
endEdit(_this,editIndex);
}
$(_this).datagrid('beginEdit', rowIndex);
$("input.datagrid-editable-input").on("keypress",function(e){
if(e.keyCode==13){
endEdit(_this,editIndex);
}
});
editIndex = rowIndex;
},
onBeginEdit: function(index, rowData){ //动态修改检测结果下拉项
var resultDictionaryDetailList = rowData.resultDictionaryDetailList
//监测结果下拉框
var goEditor = $('#project_table').datagrid('getEditor', {
index : index,
field : 'result'
});
$(goEditor.target).combobox({
onLoadSuccess: function () {
if(rowData.result){
$(goEditor.target).combobox('setValue', rowData.result);
}else{
$(goEditor.target).combobox('setValue', rowData.resultDictionaryDetailList[0].id);
}
},
onBeforeLoad: function(){ //下拉展开时动态修改options
if(resultDictionaryDetailList.length){
var data = [];
for ( var index in resultDictionaryDetailList) {
var resultDictionaryDetail = resultDictionaryDetailList[index];
data.push({'id': resultDictionaryDetail.id, 'name':resultDictionaryDetail.name});
}
$(goEditor.target).combobox("loadData", data);
}
}
});
},

具体解析如下：
onBeginEdit是将row中的下拉项数据拿出来并动态加载到Combobox 中，onBeforeLoad很重要，不然执行onLoadSuccess方法的时候，Combobox还没有动态加载下拉选项，导致显示的是值，而不是值对应的名，所以用onBeforeLoad可以先加载Combobox的下拉选项，然后再回填值
onBeginEdit: function(index, rowData){ //动态修改检测结果下拉项
var resultDictionaryDetailList = rowData.resultDictionaryDetailList
//监测结果下拉框
var goEditor = $('#project_table').datagrid('getEditor', {
index : index,
field : 'result'
});
$(goEditor.target).combobox({
onLoadSuccess: function () {
if(rowData.result){
$(goEditor.target).combobox('setValue', rowData.result);
}else{
$(goEditor.target).combobox('setValue', rowData.resultDictionaryDetailList[0].id);
}
},
onBeforeLoad: function(){ //下拉展开时动态修改options
//datatype处理统计方法
if(resultDictionaryDetailList.length){
var data = [];
for ( var index in resultDictionaryDetailList) {
var resultDictionaryDetail = resultDictionaryDetailList[index];
data.push({'id': resultDictionaryDetail.id, 'name':resultDictionaryDetail.name});
}
$(goEditor.target).combobox("loadData", data);
}
/* //设置值
if(rowData.result){
$(goEditor.target).combobox('setValue', rowData.result);
}else{
$(goEditor.target).combobox('setValue', rowData.resultDictionaryDetailList[0].name);
}*/
}
});
},
formatter是将值转换成对应的name
formatter: function (value, rowData, rowIndex) {
var resultDictionaryDetailList = rowData.resultDictionaryDetailList;
if(!value){
value = resultDictionaryDetailList[0].id;
rowData.result = value;
}
for (var i = 0; i < resultDictionaryDetailList.length; i++) {
if (resultDictionaryDetailList[i].id == value) {
return resultDictionaryDetailList[i].name;
}
}
return value;
},
