This seems like a pretty simple question but I haven't been able to find the answer anywhere.
When using data binding in AngularJS as such:
<iframe height="{{bodyHeight}}"> </iframe>
I just want to subtract a number from bodyHeight similar to:
<iframe height="{{bodyHeight - 90}}"> </iframe>
I was hoping to do so without using javascript.
What you have actually works!
You are able to do calculations and other javascript within angularJS's {{ }} data-binding!
From the angularJS documentation
Angular expressions are JavaScript-like code snippets that are usually placed in bindings such as {{ expression }}.
For example, these are valid expressions in Angular:
1+2
a+b
user.name
items[index]
I figured out what I was doing wrong. bodyHeight was being passed in as a number with px on the end like: 1280px.
So I just changed it to 1280 then the data binding is:
<iframe height="{{bodyHeight - 90}}px"> </iframe>
Pretty silly but I'll leave this here anyways for reference.
