js里咋样设置css里面的属性（css不常见属性之pointer-events的使用方法）

/* Keyword values */
pointer-events: auto;
pointer-events: none;
pointer-events: visiblePainted; /* SVG only */
pointer-events: visibleFill;    /* SVG only */
pointer-events: visibleStroke;  /* SVG only */
pointer-events: visible;        /* SVG only */
pointer-events: painted;        /* SVG only */
pointer-events: fill;           /* SVG only */
pointer-events: stroke;         /* SVG only */
pointer-events: all;            /* SVG only */

/* Global values */
pointer-events: inherit;
pointer-events: initial;
pointer-events: unset;

// html
<li class="point" onclick="alert('ok')提交申请</li>
.point {
    width: 1.8rem;
    height: .44rem;
    margin: 0 auto;
    margin-top: 0.8rem;
    text-align: center;
    line-height: .44rem;
    border-radius: 22px;
    color: #fff;
    background-color: rgba(67,76,94,.43);
    pointer-events: none;
}
