Is there a way to set the page title by data-binding using Knockout.js?

So the title tag in my HTML document looks like this:

<title data-bind="text:Title"></title>

But it doesn’t work, maybe because the tag is inside the html header?

Is there a way to do this?

Answer 1

I would create a custom binding, its super easy

To see the title in fiddle http://fiddle.jshell.net/L3nPG/show/light/

ko.bindingHandlers.pageTitle = {
    update: function(element, valueAccessor) {
        var title = ko.utils.unwrapObservable(valueAccessor());
        document.title = title;
    }
};

ko.virtualElements.allowedBindings.pageTitle = true;
