我在两个页面中使用了dijit css for dijit / horizontalSlider,滑块在第一页中加载但在第二页中变为空白。 dojoz / data / DataGrid也在第一页中正确加载,但在第二页中变为空白。
更新:
我在home.html(父页面)中有两个按钮,并调用django模板grid.html和move.html。这是grid.html源代码

首先我点击了grid.html,它正确地显示了数据,然后点击了带有水平滑块的图表的move.html,图表正常但没有滑块。 如果我第一次点击了move.html它很好(也可以获得图表和滑块)

来自DOJO and DIJIT can not parse same ID twice?:
Dojo通过指定的id跟踪它创建的对象/小部件。如果在具有相同id的对象上再次运行解析器,dojo会尝试创建第二个实例,但是已经有一个,所以它应该在js控制台中抛出错误。
在再次解析同一页面之前销毁创建的窗口小部件/对象ID。在这里,我宣布了小部件&#39;作为全局变量,所以如果有任何小部件ID,那么在解析之前就会销毁它们。
if(widgets){
widgets.forEach(function(widget) {
widget.destroyRecursive();
});
}
widgets = dojo.parser.parse();
它对我有用。

您是否检查过您的资源是否正确?我的意思是,如果你打开第二个html页面,你必须再次为这一方加载资源。
更新1
我的猜测是,因为您仍然希望使用第一页中的小部件,为第二页编写新小部件。你不能取消注册它们,因为如果你这样做,你就不能再在第一页中使用它们了。
所以,最简单的方法是为第二页写新的。第一页的值可以转移到第二页。
更新2
上次尝试:
设置html页面
单独编写javascript并在开头加载
<script type="text/javascript" src="...from/here/to/mygauge.js"</script>
此致
答案 2 :(得分:0)
我从你的代码中做了一个小提琴,它似乎运作良好。
makeObjects = function () {
var data = [4, 8, 2, 1, 6,...
此致
