Is there any way to trigger the code behind enableModifiedFlag from CCSJ or SSJS?

Question

If I set enableModifiedFlag property to true on my Custom Control; I see the following code at the bottom of generated Page source.

Everything works fine when user m

Answer 1

On click of the button, use below CSJS: XSP._setDirty(false,"") That'll make the document as non dirty and let user navigate to other page.

Answer 2

By using XSP._isDirty() from CSJS you can get true if any field was modified or false if no changes were done to your form.

So I added this block of code to my button under CSJS to display same default alert from XPages:

if (XSP._isDirty()){
    if (confirm ("Are you sure you want to navigate away from this page?" + "\n" + "\n" +
    "This document may contain unsaved changes." + "\n" + "\n" +
    "Press OK to continue, or Cancel to stay on the current page.")){
        return true;
    }else{
        return false;
    }
} else {
    return true;
}
