Twitter bootstrap 引导滑块在angular2中不工作

我使用的示例1添加了一个引导百分比滑块。我已经安装了引导滑块与npm安装引导滑块。我的component.html看起来像

following.:

<div class="lastpart">
            <div class="lasttext">
              Annual % rate of increase:
            </div>
            <input id="ex1" data-slider-id='ex1Slider' type="text" data-slider-min="0" data-slider-max="20" data-slider-step="1" data-slider-value="14"/>
          </div>

您应该在index.html中添加对引导滑块css和js文件的引用。在此处找到cdn参考：

您是否记得在bootstrap.js之前包含jquery？不，我没有！I JQuery是thins所必需的？您的脚本运行时需要一个JQuery，因此如果您添加，我已经在我的index.html中添加了这两个脚本，但结果相同！这不是答案。

<script>
    var slider = new Slider('#ex1', {
      formatter: function(value) {
        return 'Current value: ' + value;
      }
    });
</script>

    I have been using inside component file and am not getting any error and also it not working for me.

    I have included 
     "../node_modules/jquery/dist/jquery.min.js",
            "../node_modules/bootstrap/dist/js/bootstrap.min.js",
            "../node_modules/element-resize-detector/dist/element-resize-detector.min.js",
            "../node_modules/cropperjs/dist/cropper.js",
            "../node_modules/bootstrap-slider/dist/bootstrap-slider.min.js",
            "../node_modules/bootstrap-slider/dist/bootstrap-slider.js"

    same way I included css also

am following example 2 http://seiyria.com/bootstrap-slider/

my ts file code 
 ngAfterInit() {
        let ex2 = document.getElementById("ex2");
        var slider = new Slider(ex2, {
            formatter: function (value) {
                return 'Current value: ' + value;
            }
        });
        /*  let ex2 = document.getElementById("ex2");
          var slider = new Slider(ex2, {});*/
    }
and html code 

<input id="ex2" type="text" class="span2" value="" data-slider-min="10" data-slider-max="1000" data-slider-step="5" data-slider-value="[250,450]"/> <b>€ 1000</b>`enter code here`
