<!DOCTYPE html> <html> <head> <meta charset="utf-8"> <title></title> <script src="js/knockout-3.4.0.js" type="text/javascript" charset="utf-8"></script> </head> <body> <a data-bind="attr: { href: url, title: details }"> Report </a> <script type="text/javascript"> var viewModel = { url: ko.observable("year-end.html"), details: ko.observable("Report including final year-end statistics") }; ko.applyBindings(viewModel) </script> </body> </html>
如果属性绑定 data-sonmeth 和css的绑定一样，也需要加入 引号 'data-sonmeth'
下面的会报错
<!DOCTYPE html> <html> <head> <meta charset="utf-8"> <title></title> <script src="js/knockout-3.4.0.js" type="text/javascript" charset="utf-8"></script> </head> <body> <div data-bind="attr: { data-something: someValue }">...</div> <script type="text/javascript"> var viewModel = { someValue: ko.observable("{name:'data-something'}"), }; ko.applyBindings(viewModel) </script> </body> </html>
下面的时正常的
<!DOCTYPE html> <html> <head> <meta charset="utf-8"> <title></title> <script src="js/knockout-3.4.0.js" type="text/javascript" charset="utf-8"></script> </head> <body> <div data-bind="attr: { 'data-something': someValue }">...</div> <script type="text/javascript"> var viewModel = { someValue: ko.observable("{name:'data-something'}"), }; ko.applyBindings(viewModel) </script> </body> </html>
