Answer 1

使用user-select: CSS 属性:

div {
    -webkit-user-select: none;  /* Chrome all / Safari all */
    -moz-user-select: none;     /* Firefox all */
    -ms-user-select: none;      /* IE 10+ */

    /* No support for these yet, use at own risk */
    -o-user-select: none;
    user-select: none; 
}
