1.Ext.Ajax.request

Ext.Ajax.request({
    url: "url.action",
    params: {},
    success: function(response){
       var result = eval('(' + response.responseText + ')');
       if(result.success){
    	   alert("success")
       }else{
    	   alert("fail");
       }
    }
});

var task = new Ext.util.DelayedTask(function(){
	btn.setDisabled(false);
});
task.delay(10000);

2.Ext延迟执行任务

var task = new Ext.util.DelayedTask(function(){
	btn.setDisabled(false);
});
task.delay(10000);

3.Form.load

form.getForm().load({
	url:'url.action',
	method:'post',
	params:{
		id:id
	},
	success:function(form,action){
		
	},
	failure:function(form,action){
		
	}
});

4.Form.submit

form.submit({
	success : function(form, action) {

	},
	failure : function(form, action) {
	}
});

5.查询Store可以指定查询第几页

Ext.data.Store

loadPage( Number page, Object options )

Loads a given 'page' of data by setting the start and limit values appropriately. Internally this just causes a normal load operation, passing in calculated 'start' and 'limit' params

Parameters

page : Number

The number of the page to load
options : Object

See options for load

//如回到首页
store.loadPage(1);

6.Store中的Json附带除root和totalProperty以外的其他信息

Java端将otherProperty属性放入Json中，ExtJs如下写

Ext.create('Ext.data.Store', {
	storeId : 'store',
	model : 'model',
	pageSize : 20,
	proxy : {
		type : 'ajax',
		url : 'url.action',
		reader : {
			type : 'json',
			root : 'root',
			totalProperty : 'count',
			otherProperty: 'otherProperty'
		}
	}
});

如下方式可获取

store.getProxy().getReader().jsonData.otherProperty
