How to initialize the nouislider only once? noUISlider — `Uncaught Error: Slider was already initialized`

Question

我正在尝试使用 nouislider 创建范围滑块。我将使用输入字段获取最小值和最大值。单击创建按钮时，将创建一个范围滑块。

function create_range()
{

      const slider = document.getElementById('sliderPrice');

      const min_val  = document.getElementById('min').value ;
      const max_val  = document.getElementById('max').value;
      const step      = 5; // to move in 5 steps

      const filterInputs = document.querySelectorAll('input.filter__input');

      // slider.noUiSlider.reset();

      var rangeMin = parseInt(min_val);
      var rangeMax = parseInt(max_val);


       noUiSlider.create(slider, {
         start: [rangeMin, rangeMax],
         connect: true,
         // step: step, // if removed it will be in range ,smooth drag
         range: {
             'min': rangeMin,
             'max': rangeMax
         },
        
        pips: {
          mode: 'count',
          values: 5 // to split the pips
        },
        // make numbers whole
         format: {
           to: value => value,
           from: value => value
         }
      });



       // bind inputs with noUiSlider 
       slider.noUiSlider.on('update', (values, handle) => { 
         var intvalue = Math.ceil( values[handle] ); //Round a number upward to its nearest integer:
         filterInputs[handle].value = values[handle];
          // slider.noUiSlider.reset(); 
       });


       filterInputs.forEach((input, indexInput) => { 
         input.addEventListener('change', () => {
           slider.noUiSlider.setHandle(indexInput, input.value);
         })
       });

                 // slider. noUiSlider. destroy();



     
}

下次我的时候更改输入字段值并单击创建按钮，它显示错误为“noUiSlider (14.6.0): Slider was already initialized.”

如何初始化nouislider once.Or如何重置nouislider？

Answer 1

目前您无法重新初始化现有滑块。但是您绝对可以破坏滑块并创建一个新滑块。您需要添加一个检查滑块对象是否存在，基于该对象销毁现有对象然后创建一个新对象。

JS 代码如下所示。

let slider;

function destroyExistingSlider(){
  if(slider && slider.noUiSlider){
    slider.noUiSlider.destroy();
  }
}

function create_range()
{
  destroyExistingSlider();
  slider = document.getElementById('sliderPrice');
  const min_val  = document.getElementById('min').value ;
  const max_val  = document.getElementById('max').value;
  const step      = 5; // to move in 5 steps

  const filterInputs = document.querySelectorAll('input.filter__input');

  // slider.noUiSlider.reset();

  var rangeMin = parseInt(min_val);
  var rangeMax = parseInt(max_val);

    noUiSlider.create(slider, {
     start: [rangeMin, rangeMax],
     connect: true,
     // step: step, // if removed it will be in range ,smooth drag
     range: {
         'min': rangeMin,
         'max': rangeMax
     },
    
    pips: {
      mode: 'count',
      values: 5 // to split the pips
    },
    // make numbers whole
     format: {
       to: value => value,
       from: value => value
     }
  });
   

   // bind inputs with noUiSlider 
   slider.noUiSlider.on('update', (values, handle) => { 
     var intvalue = Math.ceil( values[handle] ); //Round a number upward to its nearest integer:
     filterInputs[handle].value = values[handle];
      // slider.noUiSlider.reset(); 
   });

   filterInputs.forEach((input, indexInput) => { 
     input.addEventListener('change', () => {
       slider.noUiSlider.setHandle(indexInput, input.value);
     })
   });

}
