EXT.JS从字段集中获取项目列表 [英] EXT.JS getting a list of items from a fieldset

问题描述

如何从Ext.form.Fieldset获取项目列表?我正在尝试根据其属性之一找到一个组件，这是我到目前为止所掌握的:

How can I get a list of items from a Ext.form.Fieldset? I'm trying to find a component based on one of its properties, this is what I've got so far:

Ext.each(container.items, function (component) {

    if (component.name == config.name) {
        component.doUpdate(config);
    }

}, me);

当然，项是未定义的...那么我该怎么做才能访问容器中包含的组件(这是一个字段集)?

Of course, items is undefined...so what can I do to access the components contained in my container, which is a fieldset?

推荐答案

您可以使用container.down(selector)，或者如果其表单字段使用form.findField(name).

You can use container.down(selector) or if its a form field use form.findField(name).

编辑:使用

EDIT: Use container.query(selector) method to get an array of objects. As down() method returns first found.
