[Question post] mui. openWindow + Custom Event listening allows alert () to be executed twice, mui. alert
The Alert function is executed twice.
There are two pages in total: index.html and detail.html,
Detail.html sets the Custom Event listener (newsId) for the button to trigger alert.
Click "newsid" on index.html to open the detail.html page.
Then I have two questions:
1. Is the above mentioned alert executed twice?
2. Sometimes clicking a button does not have any operations. It is possible that the document has not been loaded. Is there any solution?
The Code is as follows:
// ---Index.html <body>
// ---Detail.html <body>
------ Waiting for solution --------
