可编辑下拉列表

[李陵少]

Extjs做的可编辑下拉列表,当编辑的时候会触发什么事件?

var comb = new Ext.form.ComboBox({
name:"category2",
store:moduleStore,
valueField:'valueId',
displayField:'valueName',
mode: 'local',
triggerAction: 'all',
editable:true,
readOnly: false,
renderTo:'selectdiv',
listeners:{
select:{
fn:function(combo,record,index) {
catagoryName = record.get("valueId");
paramsObj.category = catagoryName;
store.load({params:paramsObj});
}
}
}
})

beforequery : ( Object queryEvent )
Fires before all queries are processed. Return false to cancel the query or set the queryEvent's cancel property to true.
Listeners will be called with the following arguments:
queryEvent : Object
An object that has these properties:
combo : Ext.form.ComboBox
This combo box
query : String
The query
forceAll : Boolean
True to force "all" query
cancel : Boolean
Set to true to cancel the query

谢谢你,自己瞎搞,弄出来了,我这样做的... var moduleStore = new Ext.data.Store({ proxy: new Ext.data.HttpProxy({ url: config.basic_url+'webview/videoDay_'+'getVideoCategoryTop' }), reader: new Ext.data.JsonReader({ totalProperty: "totalRecords", root: 'items', fields:['valueId','valueName'] }), listeners: { datachanged: function(obj) { storetmp = obj; var invar = document.getElementById("category2").value; for(var i=0;i<obj.length;i++){ var record = obj.getAt(i); var vn = record.get("valueName"); if(vn.indexOf(invar)==-1){ } } //obj.removeAll(); } } });
