vue3 watch监听多个属性 

watch(
    () => [tokenDialogState.tokenDialogForm.withdrawFeeMinUsdt, tokenDialogState.tokenDialogForm.coinPriceUsdt],
    ([withdrawFeeMinUsdt, coinPriceUsdt]) => {
        if (withdrawFeeMinUsdt && coinPriceUsdt) {
            tokenDialogState.tokenDialogForm.withdrawFeeMin = withdrawFeeMinUsdt / coinPriceUsdt
        } else {
            tokenDialogState.tokenDialogForm.withdrawFeeMin = ''
        }
    })

tokenDialogState.tokenDialogForm.withdrawFeeMinUsdt 和 tokenDialogState.tokenDialogForm.coinPriceUsdt 是在 reactive 定义
