解决 'Uncaught TypeError: $(...).bootstrapValidator is not a function' 错误

This error occurs when the jQuery plugin 'bootstrapValidator' is not properly loaded or initialized.

To fix this error, you should:

1. Ensure that the jQuery library is properly loaded before the bootstrapValidator plugin.

2. Make sure that the bootstrapValidator plugin is included in your HTML file and that the file path is correct.

3. Check that the bootstrapValidator plugin is initialized properly, and that the target element is selected correctly.

Here is an example of how to properly initialize the bootstrapValidator plugin:

$(document).ready(function() {
  $('#myForm').bootstrapValidator({
    // validation settings go here
  });
});

Note: Make sure to replace #myForm with the ID of the form you want to validate.
