CodePudding user response：

The technique you're looking for here is DRY, or Don't Repeat Yourself. To do this, look for the common patterns in the logic you have.

In this case each button has its text updated, and it changes the state of it's following sibling. Therefore you can place common class attributes on the elements so that the same JS logic can be applied to them all. From there you can use jQuery's DOM traversal methods to relate the elements to each other, and also data attributes to store custom metadata about the elements which can be used when the click event occurs.

Finally you can use toggleClass() to add/remove the classes to display/hide the elements as necessary.

Here's a working example:

$('.toggle').on('click', e => {
  let $btn = $(e.target);
  $btn
    .text(() => $btn.data($btn.hasClass('show') ? 'hide-text' : 'show-text')).toggleClass('show') // update text
    .next().toggleClass('inactive'); // toggle related content
})

<style>
  .inactive {
    display: none;
  }
  
  button {
    padding: 5px 25px;
    color: #fff;
    background-color: #1d9bf0;
    margin-top: 10px;
  }
</style>

<div >
  <button  data-show-text="  Show" data-hide-text="- Hide">  Show</button>
  <p >Hello WOrld</p>
</div>
<div >
  <button  data-show-text="  Ok" data-hide-text="- Cancel">  Ok</button>
  <p >Thank you</p>
