.modal（dispose）不是boostrap 4.3的函数

Question

遇到

  

未捕获的TypeError：$（...）。modal不是函数错误

当我尝试使用2

时

我不认为这是脚本参考问题，因为打开模式时不会出现任何错误，只有单击关闭并尝试执行dispose函数时，才会出现错误。

包含的库

const product1 = {
    number: '00005598001400248980',
    type: 'TC'
  },
  product2 = {
    number: '00000377820202008104',
    type: 'TA'
  },
  /**
  * @const clearMerge a function that replaces the leading zeros and returns the first 6 digits and the last 4 digits.
  *   @param n the number to be cleaned and merged.
  **/
  clearMerge = n => {
    /** 
    * 1. replace leading zeros 
    * 2. get the first 6 digits and the last 4 digits
    * 3. concatenate the digits and cast them to an integer (using "+" operator)
    * 4. return the final number
    **/
    const value = +n.replace(/^0+/, ''),
      matched = /^(\d{6}).*(\d{4})$/.exec(value);
    return +(`${matched[1]}${matched[2]}`);
  };

console.log(clearMerge(product1.number)); /** utput: 5598008980 **/

jQuery处理代码：

$('#editAppModal').modal('dispose');

错误发生在<link rel="stylesheet" href="//code.jquery.com/ui/1.11.4/themes/start/jquery-ui.css"> <script src="//code.jquery.com/jquery-1.10.2.js"></script> <script src="//code.jquery.com/ui/1.11.4/jquery-ui.js"></script> <script src="~/js/jquery-3.4.1.min.js"></script> <script src="~/js/bootstrap-4.3.1.bundle.min.js"></script> <link href="https://cdnjs.cloudflare.com/ajax/libs/select2/4.0.8/css/select2.min.css" rel="stylesheet" /> <script src="https://cdnjs.cloudflare.com/ajax/libs/select2/4.0.8/js/select2.min.js"></script> 行。
