我已经在两页中将dijit css用于dijit / horizontalSlider，滑块已在第一页中加载，但在第二页中却变得空白。 dojoz / data / DataGrid也可以在第一页中正确加载，但是在第二页中将变为空白。
更新：
我在home.html（父页面）中有两个按钮，分别调用Django模板grid.html和move.html。这是grid.html源代码

首先，我单击了grid.html并正确显示了数据，然后单击move.html以获取带有水平滑块的图表，图表运行正常，但没有滑块。
如果我第一次单击move.html可以正常工作（也可以获取图表和滑块）
最佳答案
从DOJO and DIJIT can not parse same ID twice?：
Dojo跟踪由指定ID创建的对象/小部件。如果您在具有相同ID的对象上再次运行解析器，则dojo会尝试创建第二个实例，但是已经存在一个实例，因此它应该在js控制台中引发错误。
在再次解析同一页面之前，请销毁创建的窗口小部件/对象ID。在这里，我已将“小部件”声明为全局变量，因此，如果有任何小部件ID，则在解析之前将其销毁。
if(widgets){
widgets.forEach(function(widget) {
widget.destroyRecursive();
});
}
widgets = dojo.parser.parse();
对我有用。
关于javascript - 在两页中使用了dijit css，但是仅在第一页中工作，第二页中获得空白页，我们在Stack Overflow上找到一个类似的问题：https://stackoverflow.com/questions/21721041/
