ExtJs4.2应用：使用ExtJs扩展组件searchfield

实现数据搜索功能

1.引入searchfield组件

2.在对应Js文件中引入searchfield组件

dockedItems: [{  
	        dock: 'top',   /**在顶部显示*/
	        xtype: 'toolbar', /**以工具栏形式展示*/  
	        items: {   
	            width: "25%",
	            fieldLabel: 'Login Name:',
	            labelWidth:100,
	            xtype: 'searchfield',/**searchfield 是ExtJs的扩展组件 
	                                引用路径为Ext.Loader.setPath('Ext.ux', rootPath+'/ux/')
	                                其中rootPath就是Ext类跟路径：比如http://localhost:8080/demo/Ext */
	            store: store /**对应的数据集*/  
	       }  
	    },{
	        xtype: 'pagingtoolbar',
	        store: store,
	        dock: 'bottom',
	        displayInfo: true
	    }]

3.完整的JS代码

Ext.Loader.setConfig({enabled: true});
Ext.Loader.setPath('Ext.ux', rootPath+'/ux/');
Ext.require([
	'Ext.ux.form.SearchField'

		autoLoad:true	
});
Ext.onReady(function(){
	Ext.Loader.setConfig({
		enabled:true
	});
	Ext.create('Ext.grid.Panel',{
