extjs 下拉框显示问题？

Question

listeners:{
         load: function(sto, records){
         sto.each(function(record){
         if(record.data.value !=""){
         var arr_value=record.data.value.split(",");         if(arr_value.length>1){
         record.data.editor= new Ext.grid.GridEditor(new Ext.form.ComboBox({
                         store: new Ext.data.ArrayStore({
                             fields: ['name'],
                             data: [arr_value]                         }),
                         typeAhead: true,
                         displayField: 'name',
                         selectOnFocus: true,
                         triggerAction: 'all',
                         mode: 'local'
                     }));
         }
         }
         });
            }
        }  
record.data.value的值是aaa,bb；但生成的下拉框选项中只有aaa，如果fields: ['code','name']那么下拉选框中只有bb，求解~~~
extjs 下拉框Ext JS

Answer 1

try: new Ext.form.ComboBox({
store: new Ext.data.ArrayStore({
fields: ['name'],
data: [['aaa'],['bb']]
}),
typeAhead: true,
displayField: 'name',
selectOnFocus: true,
triggerAction: 'all',
mode: 'local'
})

Answer 2

这样是可以的，但是data值每次都不一样，不能写死。

Answer 3

"aaa,bb".split(',')的数组是
['aaa','bb']这是一维数组
ext期望的是二维数组
[['aaa'],['bb']]

Answer 4

返回字符串写成json格式，不要自己解析。就能自动加载上去的。按照model，store，combo的顺序写，想出错都难。

Answer 5

listeners:{
         load: function(sto, records){
         sto.each(function(record){
         if(record.data.value !=""){
         var arr_value=record.data.value.split(",");
         var json_value=new Array();
         for(var i=0;i<arr_value.length;i++){
         json_value[i]=new Array();
         json_value[i][0] = arr_value[i];
         }         if(arr_value.length>1){
         record.data.editor= new Ext.grid.GridEditor(new Ext.form.ComboBox({
                         store: new Ext.data.SimpleStore({
                          fields: ['name'],
                             data: json_value
                         }),
                         typeAhead: true,
                         displayField: 'name',
                         selectOnFocus: true,
                         triggerAction: 'all',
                         mode: 'local'
                     }));
         }
         }
         });
            }
        }  
这样写，创建一个二维数组就正确了~~ 谢谢提示~~\(^o^)/~
