Replacing Pop-Up window with Bootstrap Modal

Question

I want to replace a pop up window with a modal in a web application. The previous implementation uses JQuery $j('input field name', opener.document); to access values stored on the previous, parent screen - this doesn't work with a modal implementation, it throws an

Uncaught TypeError: Cannot read property 'document' of null

Can anyone suggest an alternative for opener.document for use with Bootstrap Modal?

Thanks in advance

Answer 1

The code you posted is to short to give an good answer.

but i can give you an fiddle with a modal taking text from outside it.

Now i dont know what you mean by previous, parent screen.

But what i think your after is: Finding something on that's outside the modal and place it inside.

Jquery:

var text = $('some-where-you-want-info-from').html();
$('modal-body').prepend(text);`

This gets some html from an element and sets it to the modal body

Answer 2

I think the best solution is with the following syntax:

var myVar = window.parent.document.getElementById('element_name');

which seems to copy the value over exactly!

Big thanks to Persijn for pointing me in the right direction with this one!
