Re: Sorting an observableArray does not seem to work in Internet Explorer 10

[rpn]

Hello-

Technically, your sort function should return a number rather than a boolean.  Some browsers do work with a boolean, but I recall running into this issue once with Safari previously.  You could return something like Math.random() > Math.random() ? 1 : -1; or simply Math.random() - Math.random();

Look at the docs under "compareFunction" here: https://developer.mozilla.org/en-US/docs/JavaScript/Reference/Global_Objects/Array/sort

Hope that helps.

Calling observableArray.sort does not seem to do anything in Internet Explorer 10. I found this simple http://jsfiddle.net/RbX86/ that demonstrates the issue (at least on my system). The numbers are randomly sorted in Chrome but nothing happens in Internet Explorer 10 when the button is clicked.

 

Is this a bug in KnockoutJS or some strange issue on my system?

Thanks for you reply.

 

I just discovered this myself. Apparently Chrome has this additional functionality for array sorting and I happended to stumble upon sample code that was based on this.
