标记按钮“我接受隐私政策”以提交表格应该是强制性的。

<form id="form" action="">
  <label for="accept">Accept Policy Privacy</label>
  <input id="accept" type="checkbox" >
  <input type="submit" id="Send" value="Send" >
</form>

谢谢

$(function(){
  $('input#send', this).attr('disabled', 'disabled');
  $('input#accept').click(function(){
    var disabled=$('input#send').attr('disabled');
    if(disabled) {
      $('input#send').attr('disabled', false);
    }else{
      $('input#send').attr('disabled', 'disabled');
    }
  });
});
