combobox有移除某项或清空所有items的方法吗？

johnconner

var name = mini.get("combo_name");
var items = name.getColumns();
name.removeItems(items);
清空combobox,没起作用

niko

combo.setData([]);

combo.setData([]);

这是清空，那移除某一项呢？

niko

var data = combo.getData();
//data是一个数组，你可以增加、删除项，然后
combo.setData(data);

var data = combo.getData();
//data是一个数组，你可以增加、删除项，然后
combo.setData(data); ...

还有个问题要请教你，grid.load({id:id},function(){});该方法中回调函数function()能否获取服务器返回的json数据？是不是可以这样获得？function(text){alert(text);}我测试时alert出[object  object]，不知道如何能获得？
json数据：

我想在前台获得sql的值，如何做到？

niko

grid.on("load", function(e){
    e.result.sql
});
