【问题标题】:Dynamically change bootstrap progress bar value when checkboxes checked选中复选框时动态更改引导进度条值
【发布时间】:2014-02-06 13:21:44
【问题描述】:

我正在尝试使用引导进度条制作动态清单。这是我的标记代码

<div class="progress progress-striped active">
    <div class="progress-bar" role="progressbar" aria-valuenow="0" aria-valuemin="0" aria-valuemax="100">
    </div>
</div>
<div class="row tasks">
    <div class="col-md-6">
        <p><span><?php echo $title; ?></span><?php echo $description; ?></p>
    </div>
    <div class="col-md-2">
        <label><?php echo $date; ?></label>
    </div>
    <div class="col-md-2">
        <input type="checkbox" name="progress" class="progress" value="<?php echo $progress; ?>">
    </div>
    <div class="col-md-2">
        <input type="checkbox" name="done" class="done" value="<?php echo $done; ?>">
    </div>
</div><!-- tasks -->

我想要做的是,当我选中第一个复选框时,进度条值更改为复选框值,当我选中第二个复选框时,进度条值必须增加第二个复选框值,依此类推

这是我的 javascript 代码

$(document).ready(function() {
  $('.progress').change(function(event) {
    var progress_value = $(this).val();
    var newval = progress_value;
    if ($(this).is(':checked')) {
      $('.progress-bar').css("width", function(i) {
        while(newval < 100) {
          return newval+"%";
          newval+=progress_value;
        }
      });
    } else {
      $('.progress-bar').css("width", function(i) {
        do {
          newval -= progress_value;
          return newval+"%";
        } while(newval >= progress_value);
      });
    }
  });
});

    Js

    $('input').on('click', function(){
      var valeur = 0;
      $('input:checked').each(function(){
           if ( $(this).attr('value') > valeur )
           {
               valeur =  $(this).attr('value');
           }
      });
      $('.progress-bar').css('width', valeur+'%').attr('aria-valuenow', valeur);    
    });

    • 您好,谢谢您的回复。顺便说一句,这适用于第一组复选框。但我正在使用循环来生成复选框组。而且我对生成的所有组使用相同的类“进度”和“完成”。选中其余复选框时,进度条不会更新。
    • 你能提供两个复选框组的小提琴吗?
    • 对于每个输入,您必须设置要发送到导航栏的值:( input value="40" )... 看这里:bootply.com/106527
    • 别忘了用 $(document).ready(function() { .. }) 包装你的 JS,否则它可能不起作用!
    • 这对我有用:$('.progress-bar').css('width', valeur+'%').attr('aria-valuenow', valeur).html(valeur+'%');
    【解决方案2】:

    Bootstrap 4 进度条

    <div class="progress">
    <div class="progress-bar" role="progressbar" style="" aria-valuenow="" aria-valuemin="0" aria-valuemax="100"></div>
    </div>
    

    Javascript

    更改下一页/上一页操作的进度条

    var count = Number(document.getElementById('count').innerHTML); //set this on page load in a hidden field after an ajax call
    var total = document.getElementById('total').innerHTML; //set this on initial page load
    var pcg = Math.floor(count/total*100);        
    document.getElementsByClassName('progress-bar').item(0).setAttribute('aria-valuenow',pcg);
    document.getElementsByClassName('progress-bar').item(0).setAttribute('style','width:'+Number(pcg)+'%');

    • 除非你使用 Bootstrap 本机(它没有 jQuery),否则没有理由用这样的裸 JS 代码惩罚自己。 JQuery 可能不再流行,但每个人都应该承认它更易读、更简洁。
