for 属性规定 label 与哪个表单元素绑定

<form>

  <label for="male">Male</label>

  <input type="radio" name="sex" id="male" />

  <br />

  <label for="female">Female</label>

  <input type="radio" name="sex" id="female" />

</form>
for 就是为哪个标签 服务,for的值和input中的id的值时一样的

编辑/etc/config/luci

config internal 'ccache'

        option enable '0'
保存,重启

show_block_dev(){

        block_devs=$(fdisk -l | grep  "^Disk /dev/[sh]d[a-z]" | sed 's/.*\/\(.*\):.*/\1/')

        if [ -n "$block_devs" ]; then

                for i in ${block_devs} ; do

                        rmable=$(cat /sys/block/$i/removable)

                        if [ $rmable == "" ] ;then

                                choice=$i

                                dtype="Built-in DISK"

                        else

                                dtype="USB"

                        fi

                        dinfo=$(fdisk -l | grep  "^Disk /dev/$i" |awk '{print " "$2 " SIZE="$3$4}'|tr  ',' ' ')

                        echo "${GREEN} $dinfo DISK_TYPE=\"$dtype\" ${NORMAL}"

                done

        fi
