JQuery遍历webgrid行并更改标签backcolor

Question

我正在编写一个WebGrid，每个列都有标签。对于列，PREV STAT MISSION，STAT MISSION，PREV STAT QUAL和STAT QUAL，有1到4的值。我想更改标签的背景颜色以显示以下1：绿色2：黄色，3：红色和4：黑色。

如何编写一个JQuery函数，该函数将遍历webgrid中的每一行，该行将检查PREV STAT MISSION，STAT MISSION，PREV STAT QUAL和STAT QUAL的值并更改标签backcolor？

谢谢，非常感谢。

<div id="gvFacilities">
