我使用Bootstrap按钮和跨度。单击按钮时,如果结果成功,则调用ajax函数我想更改按钮类,按钮文本和跨度类。这些类正在改变,但无法正常工作。更改类时,按钮大小会增加。

<button id="check" type="" class="btn btn-danger btn-block"><span class="glyphicon glyphicon-ok-sign" aria-hidden="true"></span> Check</button>

        $("#check").click(function(){
        var lat = $('#lat').val();
        var lng = $('#lng').val();  
            $.ajax({
                type: 'post',
                url: 'kds_populate_db2.php?lat='+lat+'&lng='+lng,
                data: {
                    lat:lat,
                    lng:lng
                },
                async: true,
                cache: false,
                success: function(data) {                       
                    $("#check").addClass('btn btn-success btn-block').removeClass('btn btn-danger btn-block');
                    $('#check>span').removeClass('glyphicon glyphicon-remove').addClass('glyphicon glyphicon-ok');
                    $("#check").val("checked");

                }
            });         
    });

你的问题在这一行:

$("#check").addClass('btn btn-success btn-block').removeClass('btn btn-danger btn-block');

反转删除并添加类:

$(&#34; #check&#34;)。removeClass(&#39; btn btn-danger btn-block&#39;)。addClass(&#39; btn btn-success btn-block&#39; );

摘录:

&#13;
&#13;
$(function () {
  $('#chengeIt').on('click', function(e) {
    $("#check").removeClass('btn btn-danger btn-block').addClass('btn btn-success btn-block')[0].childNodes[1].textContent = 'Success';
    $('#check>span').removeClass('glyphicon-check').addClass('glyphicon-ok-sign');
    $("#check").val("checked");
  });
});

试试这个,如果你的尺码有问题,也许你有另一个css与你的按钮发生冲突。

$(document).ready(function(){
  $(function(){
    $("input").on("click", function(e){
      e.preventDefault();
      
      $.ajax({
        // change complete for success
        complete: function(){
          $("input").removeClass("btn-primary");
          $("input").addClass("btn-danger");
        }
      });
    });
  });
});

input{
  outline: 0!important;
}
