//neTypeStore.load();
var neTypeCombo = new Ext.form.ComboBox({
store : neTypeStore,
emptyText : "请选择",
fieldLabel : "网元类型",
isFormField : true,
id : "ne_type",
name : "ne_type",
mode : "remote",
triggerAction : "all",
valueField : "id",
displayField : "text",
editable : false,
// autoWidth: true,
width : "300",
renderTo : "ne_type_div",
listeners: {
"select":function(e,record,index){
var netype=Ext.getCmp("ne_type").getRawValue();
var ne_type=temp(netype);
var borad_state=Ext.getCmp("borad_state").getValue();
// alert(ne_type+borad_state);
//alert(ne_type.getId());
//ne_type.clearValue();
ds.proxy = new Ext.data.HttpProxy({
url : "combox.do?dispatch=element&sType="+borad_state+'&sEquipType='+ne_type+'&sEquipName='+''+'&srecordname=abcdefg&iNeedRange='+1,
method : "POST"
});
// Ext.apply(ds.store.baseParam, {sType: borad_state,sEquipType: ne_type,sEquipName: "",iNeedRange: 1});
ds.load({params:{start:0,limit:101}});
}
}
});
