超级愚蠢的问题，但我无法让它工作，我们如何从同一个函数中的另一个函数调用一个函数Controller？我使用煎茶建筑师。

这是我的控制器，我有一个监听器和一个函数，我想generateField从监听器调用函数

Ext.define('Medlemssystem.controller.MemberOrganisationController', {
    extend: 'Ext.app.Controller',

    views: [
        'LocalOrgPanel'
    ],

    onLocalOrganisationInfoAfterRender: function(component, eOpts) {

        main_id = component.up('#memberTab').main_id;

        component.removeAll();

        Ext.Ajax.request({
            url: 'OrganizationCustomFieldServlet',
            method: 'GET',
            dataType: 'json',
            params: {
                "operation" : "get",
                "org_id" : main_id 
            },
            success: function(response) {
                var result = Ext.decode(response.responseText);
                result.forEach(function(n) {
                    component.add(generateField(n.customField.name));
                });
            },
            failure: function() {
                console.log('woops');
            }
        });
    },

    generateField: function(name, type, id, required, description) {
        var field = Ext.create("Ext.form.field.Text", {fieldLabel:name});

        return field;
    },

    init: function(application) {
        this.control({
            "LocalOrgPanel": {
                afterrender: this.onLocalOrganisationInfoAfterRender
            }
        });
    }

});

当我打电话时，component.add(generateField(n.customField.name));我得到“找不到功能”错误

后onLocalOrganisationInfoAfterRender: function(component, eOpts) {

粘贴var that = this;

进而component.add(that.generateField(n.customField.name));

另一种方法是设置 ajax 请求回调的范围。

像这样

Ext.Ajax.request({
        url: 'OrganizationCustomFieldServlet',
        method: 'GET',
        dataType: 'json',
        params: {
            "operation" : "get",
            "org_id" : main_id 
        },
        success: function(response) {
           console.log(this); //<-- scope here is Window by default, unless scope is set below
        },
        failure: function() {
            console.log('woops');
        },
        scope :this //<--   Sets the controller as the scope for the success call back

    });
