Ensure that any changes made are saved before leaving the page

When a user navigates to another page without clicking the save button, I still want to call the save method. How can I implement this functionality?

If possible, could you please provide some sample code for reference...

Thank you in advance for your assistance.

Answer №1

To send an ajax request, you can utilize the following code snippet:

window.onbeforeunload = function(){ 
    ////make ajax request
}

Alternatively, you can prompt the user with a confirm box before proceeding:

function showalert() {
  if (!confirm('Are you sure you want to exit without saving changes?')) { 
     ////make ajax request
  }
  else {return true;}
}

window.onbeforeunload = function(){ showalert }

For instance, when leaving a page while working on something important, like answering questions on Stack Overflow, it's crucial to prevent accidental exits.

Answer №2

To notify when a user leaves the page, employ an ajax post activated by window.OnBeforeUnload(). This method allows passing any necessary data to keep track of user activity.

Answer №3

If you want to ensure that the save method is called even when the user navigates to another page or link, one approach is to utilize a hidden field. For example, create a hidden field named hdnSave and initially set its value to 0. Then, whenever the user navigates to a different page or clicks on a link, check if the value of the hidden field (hdnSave) is 1. If it is not, then call the Save Method. This hidden field serves as an indicator of whether the Save Method has been invoked.

Alternatively, you can achieve the same functionality by utilizing a session in C# code.
