推荐答案
您只需要使用属性等于选择器作为值，然后使用 .attr() ，就像这样:
You just need to find the right button using an attribute equals selector for the value, then set checked attribute using .attr(), like this:
$("input:radio[name='leva'][value='"+ returnedValue +"']").attr('checked', true);
由于是单选按钮，浏览器将处理其他选项的取消选择，并且如果value没有找到任何按钮...那么，像所有jQuery选择器一样，它将没有任何作用，这通常是需要的.
The browser will handle un-selecting the other options since it's a radio button, and if no button is found with the value...well, like all jQuery selectors, it just won't have any effect, which is usually what's desired.
