Maintain the itemList state after leaving the page

Question

Hello! 

I have a page with ListView, which is being filled with data from json file. It functions good, except when I leave the page and come back to it - the List is empty again.

Best regards

Hi jag0,

While leaving the page, the page will be destoryed by the system, and when visit again, the page re-create. That's why when you back to the page, the list is empty.

I thought there are two solutions for this question.

1, While init the page, fetch your json file again and fill the data into the ListView.

2, Save the data in the local storage while leaving the page and fill in when back, See this tutorial: Quickstart: Local application data (JavaScript)

Best Regards,
