我可以让它适用于文本,但无法启用它,因此它会读取图像的HTML - http://jsfiddle.net/BgQPF/
<p> Current Radiobutton Value = <span data-bind='text: selected' ></span></p>
<input type='radio' name='onlyOne' data-bind='checked: selected, enable: enable' value='<img src="https://github.com/gentoo90/minimal-django-file-upload-example/diff_blob/9ab39c7fe5abaf00f2d586e88e79a5a85075179e/src/for_django_1-3/myproject/media/documents/2012/07/12/example02.jpg?raw=true">' /> Yes
<input type='radio' name='onlyOne' data-bind='checked: selected, enable: enable' value='N' /> No
<input type='radio' name='onlyOne' data-bind='checked: selected, enable: enable' value='M' /> Maybe

你想把它输出到哪里?
在你给出的例子中,我按下第一个单选按钮时得到了正确的值,但是为什么不将href仅存储在值上并更改img元素的src attr,而不是单选按钮?
Html部分:
<p> Current Radiobutton Value = <span data-bind='text: selected' ></span></p>
<img id="test_img" src='' alt="" width="32" height="32" />
<input type='radio' name='onlyOne' data-bind='checked: selected, enable: enable' value='http://www.gravatar.com/avatar/a118c92a699e7d003b8767a108d50f53?s=32&d=identicon&r=PG' /> Yes
<input type='radio' name='onlyOne' data-bind='checked: selected, enable: enable' value='N' /> No
<input type='radio' name='onlyOne' data-bind='checked: selected, enable: enable' value='M' /> Maybe
<BR/>
<input type='checkbox' data-bind='checked: enable'> Enable controls
脚本部分:
var viewModel = {
enable: ko.observable(true),
selected: ko.observable('Y')
};
$('input[name="onlyOne"]').click(function (event) {
$('#test_img').attr('src',$(this).val());
});
ko.applyBindings(viewModel);
