Question

我是ExtJS的新手。我看到一个例子并将其复制到空白页面上。当我运行此页面时出现错误：

TypeError：Ext.state未定义 Ext.state.Manager.setProvider（Ext.create（'Ext.state.CookieProvider'））;

这是我正在尝试的完整代码：

        Ext.create('Ext.form.ComboBox', {
            fieldLabel: 'Choose',
            store: [[1, "Harpo"], [2, "Chico"], [3, "Groucho"]],
            displayField: 'name',
            typeAhead: true,
            forceSelection: true,
            valueField: 'abbr',
            renderTo: Ext.getBody(),

            stateful: true,
            stateId: 'myIdentifierUniqueAmongAllMyStatefulComponentsUsedToStoreAndFetchMyState',

            stateEvents: ['select'],

            getState: function (me) {
                // On any of the stateEvents, the framework runs this.
                // "Hey component, what do you want me to remember for you?
                return {
                    value: this.getValue()
                };
            },
            applyState: function (state) {
                // On component initialization, the framework runs this.
                // "Hey component, here's that object I saved for you
                this.setValue(state.value);
            }

        });
    </script>
</body>
</html>

我错过了什么？

你需要它：

Ext.require('Ext.state.*');

ExtJS错误“TypeError：Ext.state未定义”
