Question

Warning received in VS2012:

Validation (HTML5): If this attribute value is enclosed in quotation marks, the quotation marks must match.

When splitting data-bind parameter values onto more than one line, seems to be only when one of them contains a certain condition e.g. http://jsfiddle.net/rniemeyer/gZC5k/ – splitting line 37 onto two lines…

from: <button data-bind='click: save, enable: contacts().length > 0'>Save to JSON</button>

to:
<button data-bind='click: save,

enable: contacts().length > 0'>Save to JSON</button>

Any idea why this is triggered?

If I switch to HTML4 validation I get a warning about data-bind, same as here: Knockout.js data-bind attribute causes html validation warning

I either have some really long lines of HTML or this warning. Anything else I can do to work around this?

Answer 1

What about if you put the whole attribute on one line?

<button
    data-bind='click: save, enable: contacts().length > 0'>
    Save to JSON
</button>

That’s a bit of an improvement, though not much!
