三种方式：
使用extraParams,此法慎用
Extra parameters that will be included on every request. Individual requests with params of the same name will override these params when they are in conflict.
var myStore = Ext.create('Ext.data.Store', {
model: 'User',
proxy: {
type: 'ajax',
url: '/users.json',
extraParams:{actorid:id
},
reader: {
type: 'json',
root: 'users'
}
},
autoLoad: true
});
2.监听beforeload事件
var myStore = Ext.create('Ext.data.Store', {
model: 'User',
proxy: {
type: 'ajax',
url: '/users.json',
reader: {
type: 'json',
root: 'users'
}
},
listeners:{beforeload:function(store,operation, eOpts){
operation.params.actorid=id;
}},
autoLoad: true
});
3.重载/自定义pagingbar工具栏
/* MODIF BY HTZ 修正分页工具栏查询问题 */
Ext.define('Ext.toolbar.Paging', {
override : 'Ext.toolbar.Paging',
moveFirst : function() {
if (this.fireEvent('beforechange', this, 1) !== false) {
var params = this.store.lastOptions.params;
if (params) {
delete params.start;
delete params.limit;
delete params.page;
}
this.store.loadPage(1, {
params : params
});
}
},
/**
* Move to the previous page, has the same effect as clicking the 'previous'
* button.
*/
movePrevious : function() {
var me = this, prev = me.store.currentPage - 1;
if (prev > 0) {
if (me.fireEvent('beforechange', me, prev) !== false) {
var params = me.store.lastOptions.params;
if (params) {
delete params.start;
delete params.limit;
delete params.page;
}
me.store.previousPage({
params : params
});
}
}
},
/**
* Move to the next page, has the same effect as clicking the 'next' button.
*/
moveNext : function() {
var me = this, total = me.getPageData().pageCount, next = me.store.currentPage
+ 1;
if (next <= total) {
if (me.fireEvent('beforechange', me, next) !== false) {
var params = me.store.lastOptions.params;
if (params) {
delete params.start;
delete params.limit;
delete params.page;
}
me.store.nextPage({
params : params
});
}
}
},
/**
* Move to the last page, has the same effect as clicking the 'last' button.
*/
moveLast : function() {
var me = this, last = me.getPageData().pageCount;
if (me.fireEvent('beforechange', me, last) !== false) {
var params = me.store.lastOptions.params;
if (params) {
delete params.start;
delete params.limit;
delete params.page;
}
me.store.loadPage(last, {
params : params
});
}
},
/**
* Refresh the current page, has the same effect as clicking the 'refresh'
* button.
*/
doRefresh : function() {
var me = this, current = me.store.currentPage;
if (me.fireEvent('beforechange', me, current) !== false) {
me.store.loadPage(current, me.store.lastOptions);
}
}
});
