问题:首先点击提交 btn 一切正常，导入了 5 个滑块.第二次单击，应该更新，但我收到此消息:

Problem: First click in submit btn all works well, 5 sliders are imported. Second click, an update is supposed, but i get this message:

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

推荐答案

只是为了补充@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:

Just to add on to @missingo's answer and @Kevin's comment. You could walk through the existing dijits by looking in the registry:

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.
*/
