綁定和取消綁定是搞亂了我

當用戶滾動到條款的底部會在a#submit按鈕刪除類，一旦你點擊a#submit它會刪除類禁用a#submitbutton。所有類型的作品，但它需要兩次點擊才能刪除第一類，如果你不向下滾動，它會增加一個類的亮點，這也需要兩個點擊！爲什麼需要兩次鼠標點擊，我認爲這是綁定和我的蹩腳代碼？綁定和取消綁定是搞亂了我

<style> 
p { 
    padding: 0.25em; 
} 
#terms { 
    border: solid 1px; 
    height: 24em; 
    overflow: auto; 
    margin-bottom: 1em;

    padding: 0.5em 0;

<script type="text/javascript"> 
// Select the elements of the HTML page. 
jQuery(document).ready(function() { 
    var instructions = jQuery('#instructions'), 
     terms = jQuery('#terms'), 
     termsInner = jQuery('#termsInner'), 
     submit = jQuery('#submit');  
      submit.bind('click', function() { 
       instructions.addClass('highlighted'); 

       setTimeout(function() { 
        instructions.removeClass('highlighted'); 
       }, 2000); 
      }); 

      terms.scroll(function() { 
       if (terms.scrollTop() + terms.height() >= termsInner.height()) { 
        submit.unbind('click').bind('click', showTest); 
        jQuery("a#submit").removeClass("disablebtn"); 
       } 
      }); 

      function showTest() { 
       jQuery("a#submitbutton").removeClass("disablebtn"); 
       jQuery("a#submit").removeClass("disablebtn"); 
       jQuery('a#submit').click(function() { 
       jQuery("a#submitbutton").removeClass("disabled"); 
      }); 
      } 

}); 
</script> 
</head> 
<body> 
<p id="instructions">Please read these terms and conditions now. <b>You must scroll to the bottom before continuing.</b></p> 
<div id="terms"> 
    <div id="termsInner"> 
     <p>Lorem ipsum dolor sit amet, consectetur adipiscing elit. Nam sit amet mauris rhoncus libero congue interdum a ac dolor. In tellus enim, vulputate nec rhoncus nec, sollicitudin non lorem.

    </div> 
</div> 
<a href="#" class="button disablebtn" id="submit">I Agree to CLEAR's Terms & Conditions</a> 
<a href="#" id="submitbutton" class="subButton disabled">Submit</a>

這實際上固定的＃提交按鈕移除類雙擊：

<script type="text/javascript"> 
terms.scroll(function() { 
     if (terms.scrollTop() + terms.height() >= termsInner.height()) { 
         jQuery("a#submit").removeClass("disablebtn"); 
          submit.unbind('click').bind('click', showTest); 
         jQuery('a#submit').click(function() { 
         jQuery("a#submitbutton").removeClass("disabled"); 
          }); 
         } 
        }); 

        function showTest() { 
         jQuery("a#submitbutton").removeClass("disablebtn"); 
         jQuery("a#submit").removeClass("disablebtn"); 

        } 
</script>

不要即使所有的綁定和解除綁定打擾。讓你的一個事件處理程序找出適當的操作。您可以使用一個簡單的布爾變量來跟蹤用戶是否已經到達底部：

var scrolled = false; 
terms.scroll(function() { 
    scrolled = true; 
    jQuery("a#submit").removeClass("disablebtn"); 
}); 

submit.bind('click', function() { 
    if (scrolled) { 
     showTest(); 
    } else { 
     instructions.addClass('highlighted'); 

     setTimeout(function() { 
      instructions.removeClass('highlighted'); 
     }, 2000); 
    } 
});
