单击按钮启用和禁用

Question

所以我有这个 link 可以按

<a href="link" target="_blank">
    <div class="well">
        <span> blabla </span>
    </div>
</a>

页面中的这个按钮代码

<button  type="submit" class="btn-primary btn-lg" disabled="disabled"> Blabla </button>

如您所见，该按钮暂时处于禁用状态。当我按下 link 按钮再次启用时，我该如何做到这一点？抱歉我的英语不好..

Answer 1

我建议在您的按钮和 link 中添加 id 属性，以便使用 Javascript 更容易访问它们。假设您将 id="myButton" 分配给按钮，将 id="myLink" 分配给锚标记：

$('#myLink').on('click', function() {
   $('#myButton').prop('disabled', false);
});

Answer 2

希望这段代码有用

document.getElementById('click').onclick = function(event){
// on click prevent the default behavior
event.preventDefault();
document.getElementsByClassName('btn-primary')[0].disabled = false;
}

给你：

$(document).ready(function(){
  $("a").click(function(){
    $("button[type='submit']").removeAttr('disabled');
  });
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
 <a href="link" target="_blank"><div class="well">
    <span> blabla </span>
    <div></a>
   
<button  type="submit" class="btn-primary btn-lg" disabled="disabled"> Blabla </button>

Answer 4

Try this generalized function for toggleDisabled

//Generalized function to make element toggleDisabled.
(function($) {
    $.fn.toggleDisabled = function(){
        return this.each(function(){
            this.disabled = !this.disabled;
        });
    };
})(jQuery);
//Code to use toggleDisabled
$(document).ready(function(){
  $("a").click(function(){
      $("button[type='submit']").toggleDisabled();
  });
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<a href="link" target="_blank">
    <div class="well">
        <span> blabla </span>
    <div>
</a> 
<br/>      
<button  type="submit" class="btn-primary btn-lg" disabled="disabled"> Blabla </button>
