Question

我使用以下代码：

require([
    "dojo/_base/declare",
    "dojo/ready", 
    "dijit/registry", 
    "dojox/mobile/ListItem",
    "dojox/mobile/EdgeToEdgeList",
    "dojo/dom-construct",
    "dojox/mobile/ProgressBar",
    "dojo/parser", 
    "dojox/mobile",
    "dojox/mobile/compat", // For non-webkit browsers (FF, IE)
    "dojox/mobile/ScrollableView"
], function(declare, ready, registry, ListItem, LongListMixin,
    EdgeToEdgeList, domConstruct, ProgressBar) {

    ready(function() {
        console.log("inside init Videos2");
        mainRegistry = registry;
        scrollableListItem = ListItem;
        ..........

我收到以下错误：

Uncaught Error: declare: mixin #0 is not a callable constructor.

我假设您正在某处使用dojox/mobile/LongListMixin添加为mixin。问题是您未在require()列表中包含该模块。

根据您的参数，您需要LongListMixin和dojox/mobile/ListItem之间的dojox/mobile/EdgeToEdgeList。将其添加到那里，以便require()成为：

require([
    "dojo/_base/declare",
    "dojo/ready", 
    "dijit/registry", 
    "dojox/mobile/ListItem",
    "dojox/mobile/LongListMixin", // This was missing
    "dojox/mobile/EdgeToEdgeList",
    "dojo/dom-construct",
    "dojox/mobile/ProgressBar",
    "dojo/parser", 
    "dojox/mobile",
    "dojox/mobile/compat", // For non-webkit browsers (FF, IE)
    "dojox/mobile/ScrollableView"
], function(declare, ready, registry, ListItem, LongListMixin,
    EdgeToEdgeList, domConstruct, ProgressBar) {

    // ...

});

如果你没有添加它，列表中的下一个参数（dojox/mobile/EdgeToEdgeList）将被映射到LongListMixin参数，从而导致错误，因为这并不是真正的预期

对我来说，错误意味着我的需求清单中的文件是假的。意味着dojo无法使用它。这是我创建的文件。一旦我把那个错误消失了，我得到了我想要的结果。
