javascript函數驗證從php的一個數字？

Question

如何讓一個javascript函數來驗證一個數字是否在php的最小和最大數之間？

$dbosminsalary 
$dbosmaxsalary 
$dblastdate 

<form action='workaction.php' method='post'> 

<input type='number' id='amntpreferred' name='amntpreferred' class='required input_field' placeholder='Enter bid value' oninput='numberBetween();' required/> 

<script> 

function numberBetween(amntpreferred, $dbosmaxsalary, $dbosminsalary) 
{ 
    if(amntpreferred <= $dbosminsalary) 
      return false; 
    else if(amntpreferred >= $dbosmaxsalary) 
      return false; 
    else 
      return true; 
} 
if (numberBetween(amntpreferred,$dbosmaxsalary,$dbosminsalary)) 
{ 
    echo 'The value is in the range!'; 
} 
else 
{ 
    echo 'The value is outside the range!'; 
} 
</script>

對這個例子看看這裏

<?php 

$min = 1; 
$max = 10; 

?> 

<script> 
    function inRange(x) { 

     if((x >= <?php echo $min; ?>) && (x <= <?php echo $max; ?>)) 
      return true; 

     return false; 
    } 

    if(inRange(77)) 
     alert("it's ok"); 
    else 
     alert("it's not ok"); 

</script> 

現在請有仔細檢查了一番，並嘗試實施它在你的代碼中，最重要的事情是，你瞭解它
