尝试使用 id==valores0 注册小部件，但该 id 已注册

我收到此错误，我不知道如何解决。我读这个链接 https://stackoverflow.com/questions/2222517/error-tried-to-register-widget-with-id-grid1but-that-id-is-already-registered before.

问题：第一次单击提交按钮一切正常，导入了 5 个滑块。第二次单击，应该进行更新，但我收到此消息：

Tried to register widget with id==valores0 but that id is already registered

只是添加@missingo 的答案和@Kevin 的评论。您可以通过查看注册表来浏览现有的 dijit：

var i = i || 0; // Cache this at the end of your loop
dijit.registry.map(function (widget) {
    if (+widget.id.replace(/^[^\d]+/, '') <  i) {
        widget.destroyRecursive();
    }
});
/*
    Your loop fixed as described in missingno's answer.
