这句话：

var runflat = document.getElementById("runFlat")

应改为：

var runflat = document.getElementById("runflat")

这是因为JavaScript中的in区分大小写。

顺便提一句，我认为const rf = $(runflat).val();这条线行不通。每次只需将rf设置为"on"即可。更正确的方法是这样做：

const rf = $("input[id='runflat']:checked").val();

如果选中单选按钮，这将将rf设置为"on"，如果不是，则设置为undefined。如果要更改这些值，可以使用Elvis运算符：

const rf = $("input[id='runflat']:checked").val() ? "yes" : "no";

现在，如果选中单选按钮，rf将被设置为"yes"，如果不是，则设置为"no"。
