推荐答案

最简单的方法是移除 optionsValue 绑定.如果不指定 optionsValue 绑定，则整个项目将是选定的值.

The simplest way to do it is to remove the optionsValue binding. When you don't sepcify the optionsValue binding, the entire item will be the selected value.

<select id="projectMenu" name="projectMenu" data-bind="   
        value: selectedProject,
        options:        projectFilters,
        optionsText:    'a',         
        optionsCaption: '-- Select Project --'
    ">
    </select>
<b>Selected Project:
<span data-bind="text: selectedProject() ? selectedProject().a : 'no selection '"></span>
