extjs函数调用方法?

Question

init: function() {this.control({'userlist textfield[id=searchId]':{keyup:function(textfield, e){if (e.getKey() == 13) {this.searchUserByEnter //此处该如何调用searchUserByEnter 所标记的方法}}}}searchUserByEnter:function(textfield){alert('call search function')var grid = textfield.ownerCt.ownerCt,store =grid.getStore(),tbar=textfield.ownerCt,searchInfo= tbar.down('textfield').getValue();store.on('beforeload', function (store, options) {var param = {param:searchInfo};Ext.apply(store.proxy.extraParams, param);});var pagebar = grid.down('pagingtoolbar');pagebar.movePrevious();grid.getStore().load({params:{ start:0, limit:5}});}

Answer 1

当前this所引用的作用域已经改变了,可简单修改为
init: function() {
var me = this;//保存作用域
this.control({
'userlist textfield[id=searchId]':{
keyup:function(textfield, e){

if (e.getKey() == 13) {
me .searchUserByEnter(textfield); //调用原作用域方法
}
}
}
}
规范点可参照extjs写成scope参数控制this
