javascript editing prompt -

-

I am creating a web application in which I must show the user's edit signal to navigate through the page.

I want to show it only when the user edits some values ​​on that page and does not save the change, then the prompt "Do you want to save changes?" Will ask. Otherwise, the prompt does not appear if it is saved.

A processing signal similar to Microsoft Word / Excel informs you that you are making changes and you want to proceed.

Please solve the solution faster?

You can use onbeforeunload :

Although support is limited because it is based on some invention of Microsoft and others have copied it. It is not possible to do whatever you want in a browser that does not support this incident.

Currently, all of this is run simultaneously in one line, and I want to break it into my elements, with line break and indenting it makes it a little easier to read. Here is the code I'm using to save a FlowDocument in a WPF RichTextBox as a XAML file: // entire document around TextRange textRange Create a TextRange side = new TextRange (myRichTextBox.Document.ContentStart, myRichTextBox.Document .contentEnd); // save the file using the file (file stream fs = file.

This is used to work so I'm not sure what's wrong the user just logs in to Facebook properly Is capable of Logging problem. I log out the user logout by redirecting them to the php script. $ facebook-> GetLogoutUrl (); When users click on that link, they are logged out from the Facebook page.
