如何显示隐藏的输入字段

Question

I have a question.

When I have form with lets say about 100 hidden input fields, how can I show them one by one after I press enter in the last shown input field?

Answer 1

This adds a key handler to each type="text" field. The key handler tests whether the field is the last type="text" field, and if the key was the Enter key. If so, it finds the next type="hidden" field, sets its type to "text", and adds the handler to it.

 function callback(e){ if ( // If it's the last text field $(this).index() == $('#demo input[type="text"]').length - 1 && // And the key pressed is Enter: e.which == 13 ) { // Find next hidden field, change it to text, and add the key handler: $(this).next('input[type="hidden"]').prop("type", "text").keypress(callback) } } // Add key handler to all text fields: $('#demo input[type="text"]').keypress(callback)

 <script src="https://code.jquery.com/jquery-3.6.0.js" integrity="sha256-H+K7U5CnXl1h5ywQfKtSj8PCmoN9aaq30gDh27Xc0jk=" crossorigin="anonymous"></script> <div id="demo"> <input type="text"> <input type="text"> <input type="text"> <input type="hidden" value="hidden1"> <input type="hidden" value="hidden2"> <input type="hidden" value="hidden3"> </div>
