使用dijit css在两个页面，但仅在第一页工作，在第二页获得空白页 [英] Used dijit css in two pages, but working in first page only, in second page getting blank page
问题描述
我在dijit / horizontalSlider中使用了dijit css两页，滑块正在第一页被加载，但在第二页中变为空白。 dojoz / data / DataGrid也正确地加载到第一页，但第二页空白。
I have used dijit css for dijit/horizontalSlider in two pages , slider is getting loaded in first page but in second page getting blank. dojoz/data/DataGrid also loaded correctly in first page, but in second page getting blank.
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。这里是grid.html源代码
I have two buttons in home.html(parent page) and calling django templates grid.html and move.html. Here is grid.html source code

首先，我点击了grid.html，并在点击移动后正确显示了数据。 html图表与水平滑块，图表正确，但没有滑块在那里。
如果我点击move.html第一次它是wokring罚款（获取图表和滑块也）
First I have clicked on grid.html and it displayed the data correctly, after that clicked on move.html for chart with horizontal sliders, chart came properly but no sliders are there. If I clicked move.html first time it is wokring fine(getting chart and sliders also)
推荐答案
从<一个href =https://stackoverflow.com/a/15889588> DOJO和DIJIT不能两次解析相同的ID ：
Dojo跟踪由指定的id创建的对象/小部件。如果您在同一个id的对象上再次运行解析器，dojo会尝试创建一个第二个实例，但是已经有一个实例，所以应该在你的js控制台中抛出一个错误。
Dojo keeps track of the objects / widgets it creates by the specified id. If you run the parser again on an object with the same id, dojo tries to create a second instance, but there is already one, so it should throw an error in your js console.
在再次解析同一页面之前，销毁创建的小部件/对象标识。在这里我已经将小部件声明为全局变量，所以如果有任何小部件ids在解析之前就摧毁它们。
Destroy the created widget/object ids before you parse the same page again. Here I have declared 'widgets' as global variable, so that if any widgets ids are there just destroying them before parsing.
if(widgets){
widgets.forEach(function(widget) {
widget.destroyRecursive();
});
}
widgets = dojo.parser.parse();
它适用于我。
这篇关于使用dijit css在两个页面，但仅在第一页工作，在第二页获得空白页的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持IT屋！
