Sencha Touch 2 - 从控制器到视图的传递值是“未定义”

我将值传递给来自控制器的视图中的过滤器存储视图。来自控制器的值未定义

我的控制器： 

showCatQuery: function(list,index,element,record){
        var catid = record.get('id'); << Value to pass
        this.getNavigation().push({
            xtype: 'panel',
            title: 'A',
            scrollable: true,
            styleHtmlContent: true,
            catid: catid,
            layout: {
                type: 'fit'
            }, 
            items: [
                {
                    xtype: 'showSearchCategory',
                }
            ]
        });
    }

我在初始化中的观点 

this.callParent(arguments);
        var sto = Ext.getStore('allapp');
        sto.clearFilter();
        sto.filter('categoryid', this.config.catid);

我把代码放错了。但是未定义值。

哪里代码错了？

答案 0 :(得分：0)

假设您的视图在catid定义中有config，您应该使用setter / getter访问该属性：

sto.filter('categoryid', this.getCatid());

添加到config的项目会自动为它们设置/获取。

**编辑**

我正在添加您应该使用的完整视图代码。 this.getCatid()无法在initialize方法中提供价值的唯一原因是，如果您没有传递值。

Ext.define('Catalog.view.showSearchCategory', {
    extend: 'Ext.navigation.View',
    xtype: 'showSearchCategory',
    requires: ['Ext.data.Store'],
    config: {

        catid: null,

        navigationBar: false,
        items: [
            {
                title: "All Apps",
                xtype: 'list',
                // id:'Applist',
                itemTpl: new Ext.XTemplate(
                    '<img src="http://127.0.0.1:3000/system/appinfos/appicons/000/000/{id}/original/{appicon_file_name}" width="50" heigh="50" style="float:left;clear:both;"></img>',
                    '<div style="margin-left: 60px;word-wrap: break-word;width:80%;">',
                    '<span style="font-size:16px;">{name}</span><br>',
                    // '<tpl for="categories">',
                    '<span style="font-size:13px;color:#7C7C7C;" id="catname">{categoryname}</span>',
                    '</div>'
                    // '</tpl>'

                ),
                store: {
                    autoLoad: true,
                    storeId: 'allapp',
                    fields: ['id','name','created_at','appicon_file_name','categoryid','categoryname','url_ios','url_android','gallery','description'],
                    sorters: [{
                        property:'created_at',
                        direction:'DESC'
                    }],
                    proxy: {
                        type: 'jsonp',
                        url: 'http://127.0.0.1:3000/appinfos.json',
                        reader:{
                            type: 'json',
                            rootProperty:'appinfos'
                        }
                    }
                }
            }
        ]
    },
    initialize: function() {
        console.log(this.getCatid());
        var sto = Ext.getStore('allapp');
        sto.clearFilter();
        sto.filter('categoryid', this.getCatid());

        this.callParent(arguments);
    }


});

查看：

showCatQuery: function(list,index,element,record){
    var catid = record.get('id'); 
    this.getNavigation().push({
        xtype: 'panel',
        title: 'A',
        scrollable: true,
        styleHtmlContent: true,
        layout: {
           type: 'fit'
        },
        items: [
            {
                xtype: 'showSearchCategory',
                catid: catid
            }
        ]
    });
}
