Using knockout with property names containing “:” (or other special characters)

问题

I am using knockout data binding to render an editor for a string => string dictionary. However, I'm running into trouble when dictionary keys contain special characters such as colon. Is there a way to "escape" a property name or special character such that knockout will bind properly? For example, the following does not bind properly:

<p data-bind="text: foo::bar" />

I am using version 2.1.0 of knockout

回答1:

You need to use $data to access the currently bound object and from there the array indexer syntax to access any of its properties which are containing special characters:

<p data-bind="text: $data['foo::bar']" />

Demo JSFiddle.
