Ext 貌似有个grid吧 可以做列表

Answer 2

我干学Ext不久，能具体点吗？

Answer 3

可以用multiselect
看官方示例：ext-2.2/examples/multiselect/multiselect-demo.html

Answer 4

Ext.onReady(function(){    Ext.QuickTips.init();
    Ext.form.Field.prototype.msgTarget = 'side';
    
    /*
     * Ext.ux.Multiselect Example Code
     */
    var msForm = new Ext.form.FormPanel({
        title: 'MultiSelect Test',
        width:700,
        bodyStyle: 'padding:10px;',
        renderTo: 'multiselect',
        items:[{
            xtype:"multiselect",
            fieldLabel:"Multiselect<br />(Required)",
            name:"multiselect",
            dataFields:["code", "desc"], 
            valueField:"code",
            displayField:"desc",
            width:250,
            height:200,
            allowBlank:false,
            data:[[123,"One Hundred Twenty Three"],
                ["1", "One"], ["2", "Two"], ["3", "Three"], ["4", "Four"], ["5", "Five"],
                ["6", "Six"], ["7", "Seven"], ["8", "Eight"], ["9", "Nine"]],
            tbar:[{
                text:"clear",
                handler:function(){
                msForm.getForm().findField("multiselect").reset();
            }
            }]
        }],
        tbar:[{
            text: 'Options',
            menu: [{
            text:"Set Value (2,3)",
            handler: function(){
                msForm.getForm().findField("multiselect").setValue("2,3");
            }
        },{
            text:"Toggle Enabled",
            handler: function(){
                var m=msForm.getForm().findField("multiselect");
                if (!m.disabled)m.disable();
                else m.enable();
            }
            }]
        }],
        
        buttons: [{
            text: 'Save',
            handler: function(){
                if(msForm.getForm().isValid()){
                Ext.Msg.alert('Submitted Values', 'The following will be sent to the server: <br />'+ 
                    msForm.getForm().getValues(true));
                }
            }
        }]
    });
           
});
注意导入Ext.ux.Multiselect组件的类MultiSelect.js文件
