我尝试使用我的popover选择列表项显示文本框，它不显示，这个问题怎么样？请帮我解决这个问题，我试着去做但不解决这个问题，看看代码这是结构，你可以理解它 Image

我的代码部分 的 HTML 

$(document).ready(function() {
     $('.popr').popr();
});

$(document).on('click', '#feugait', function () {
     alert('Feugait');
});
$(document).ready(function() {
     $('[data-toggle="popover"]').popover();

     $('[data-toggle="popover"]').on("click",function(){
     	 $("#messageTextBox").val($(this).find("div").text());
     });
});


(function($) {

     $.fn.popr = function(options) {

          var set = $.extend( {

               'speed'        : 200,
               'mode'         : 'bottom'

          }, options);

          return this.each(function() {

               var popr_cont = '.popr_container_' + set.mode;
               var popr_show = true;

               $(this).click(function(event)
               {
                    $('.popr_container_top').remove();
                    $('.popr_container_bottom').remove();

                    if (popr_show)
                    {
                         event.stopPropagation();
                         popr_show = false;
                    }
                    else
                    {
                         popr_show = true;
                    }

                    var d_m = set.mode;
                    if ($(this).attr('data-mode'))
                    {
                         d_m = $(this).attr('data-mode')
                         popr_cont = '.popr_container_' + d_m;
                    }

                    var out = '<div class="popr_container_' + d_m + '"><div class="popr_point_' + d_m + '"><div class="popr_content">' + $('div[data-box-id="' + $(this).attr('data-id') + '"]').html() + '</div></div></div>';

                    $(this).append(out);

                    var w_t = $(popr_cont).outerWidth();
                    var w_e = $(this).width();
                    var m_l = (w_e / 2) - (w_t / 2);

                    $(popr_cont).css('margin-left', m_l + 'px');
                    $(this).removeAttr('title alt');

                    if (d_m == 'top')
                    {
                         var w_h = $(popr_cont).outerHeight() + 39;
                         $(popr_cont).css('margin-top', '-' + w_h + 'px');
                    }

                    $(popr_cont).fadeIn(set.speed);
               });

               $('html').click(function()

你需要知道的是，元素id只能在页面上有一个，但是你可以有很多class，你可以在没有定义的情况下调用jQuery插件.popr()，然后调用它。 

(function($) {
  $.fn.popr = function(options) {
    var set = $.extend({
      'speed': 200,
      'mode': 'bottom'
    }, options);

    return this.each(function() {

      var popr_cont = '.popr_container_' + set.mode;
      var popr_show = true;

      $(this).click(function(event) {
        $('.popr_container_top').remove();
        $('.popr_container_bottom').remove();

        if(popr_show) {
          event.stopPropagation();
          popr_show = false;
        }
        else {
          popr_show = true;
        }

        var d_m = set.mode;
        if($(this).attr('data-mode')) {
          d_m = $(this).attr('data-mode')
          popr_cont = '.popr_container_' + d_m;
        }

        var out = '<div class="popr_container_' + d_m + '"><div class="popr_point_' + d_m + '"><div class="popr_content">' + $('div[data-box-id="' + $(this).attr('data-id') + '"]').html() + '</div></div></div>';

        $(this).append(out);

        var w_t = $(popr_cont).outerWidth();
        var w_e = $(this).width();
        var m_l = (w_e / 2) - (w_t / 2);

        $(popr_cont).css('margin-left', m_l + 'px');
        $(this).removeAttr('title alt');

        if(d_m == 'top') {
          var w_h = $(popr_cont).outerHeight() + 39;
          $(popr_cont).css('margin-top', '-' + w_h + 'px');
        }

        $(popr_cont).fadeIn(set.speed);
      });

      $('html').click(function() {
        $('.popr_container_top').remove();
        $('.popr_container_bottom').remove();
        popr_show = true;

答案 1 :(得分：0)

我不应该包含空格您只需删除category：

<input class="form-control input-sm" id="messageTextBox" type="text" placeholder="Select category">

同样的说明也应适用于id="popover-sectio selectBox"。

注意：您正在将onchange个事件附加到div并尝试访问value的{​​{1}}个属性，从那时起就没有。

希望这有帮助。
