我只是在学习煎茶触摸 2，MVC。我会制作一个简单的表单来获取值，传递给 PHP 文件（用于对 Web 服务的 API 调用），移动到嵌套列表并显示结果。但是，我的应用程序在提交后没有显示任何内容......值被正确捕获（我在控制台日志中看到它）。请问有人可以帮我吗？

考虑测试一下，我现在不传递值，并且我的 API 调用直接使用硬编码值调用。将来我会努力传递表单价值......

先感谢您！

这是“app.js”

Ext.application({
  name:                     'Appre',
  icon:                     'resources/icons/icon.png',
  phoneStartupScreen:   'resources/images/phone_startup.png',
  //tabletStartupScreen: 'tablet_startup.png',
  glossOnIcon:          false,
  //profiles:           ['Phone', 'Tablet'],
  views :       ['Viewport','SearchCap','ElencoRistoranti'],
  models:           ['ElencoRistoranti'],
  stores:           ['RistorantiCap'],
  controllers:  ['SearchCap'],
  viewport: {
    layout: {
        type: 'card',
        animation: {
            type: 'slide',
            direction: 'left',
            duration: 300
        }
    }
},
launch: function() {
    Ext.create('Appre.view.Viewport')
} // launch: function() {
}) // Ext.application

这是表格“搜索帽”

Ext.define('Appre.view.SearchCap', {
extend: 'Ext.form.Panel',
xtype: 'appre-searchCap',
config: {
    items: [{
        xtype: 'fieldset',
        layout: 'vbox',
            items: [{
                xtype: 'textfield',
                name: 'cap',
                placeHolder: 'Cap' 
            },
            {
                xtype: 'button',
                text: 'Cerca',
                action :'searchCap',
                id:'btnSubmitLogin'
            }] // items
    }] // items
}, // config
initialize: function() {
    this.callParent(arguments);
    console.log('loginform:initialize');
}
});

这是控制器

Ext.define('Appre.controller.SearchCap', {
extend : "Ext.app.Controller",
config : {
    refs : {
        btnSubmitLogin: 'button[action=searchCap]',
        form : 'appre-searchCap'
    },
    control : {
        btnSubmitLogin : {
            tap : "onSubmitLogin"
        }
    }
},
onSubmitLogin : function() {
    console.log("onSubmitLogin");
    var values = this.getForm().getValues();
    console.log(values);
    var $this=this;
    Ext.Ajax.request({
        url: 'cerca-ristoranti-cap.php',
        method: 'POST',
        params: {
            values: Ext.encode({form_fields: values})
        },
        success: function(response, opts) {
            var obj = Ext.decode(response.responseText);
            //Ext.Msg.alert('Contact Complete!', obj.responseText);
            $this.resetForm();
            Ext.Viewport.add(Ext.create('Appre.view.ElencoRistoranti'));
            Ext.Viewport.setActiveItem(Ext.create('Appre.view.ElencoRistoranti'));
        },
        failure: function(response, opts) {
            console.log('server-side failure with status code ' + response.status);
        }
    });
},
resetForm: function() {
this.getForm().reset();
},
    launch : function() {
        this.callParent();
        console.log("LoginForm launch");
    },
    init : function() {
        this.callParent();
        console.log("LoginForm init");
    }
});

这是嵌套列表

Ext.define('Appre.view.ElencoRistoranti', {
extend: 'Ext.Panel',
xtype: 'appre-elencoristoranti',
config: {
    xtype: 'nestedlist',
    title: 'Cap',
    displayField: 'name',
    store: {
        type: 'tree',
        fields: [
            'id_restaurant', 'name',
            {name: 'leaf', defaultValue: true}
        ],
        root: {
            leaf: false
        },
        proxy: {
            type: 'ajax',
            url: 'cerca-ristoranti-cap.php',
            reader: {
                type: 'json',
                rootProperty: 'restaurants'
            } //reader
        } // proxy
    },
    detailCard: {
        xtype: 'panel',
        scrollable: true,
        styleHtmlContent: true
    },
    listeners: {
        itemtap: function(nestedList, list, index, element, post) {
            this.getDetailCard().setHtml(post.get('name'));
        }
    }
} // config
});

cerca-ristoranti-cap.php 它是一个简单的函数，它返回如下数组：

{
"restaurants":[{
    "id_restaurant":"40",
    "name":"La Saliera",
    "zip":"00128",
    "lat":"41.7900229",
    "lgt":"12.4513128"
}, {
    "id_restaurant":"64",
    "name":"Osteria del Borgo",
    "zip":"00128",
    "lat":"41.7887363",
    "lgt":"12.5149867"
}]

}

嗨@sineverba 抱歉回复有点晚了，但这里有一些你想要展示的东西，
