Ensure that the user remains within the current div when they click the submit button, even if the textbox is

For the past 48 hours, I've been grappling with an issue on my HTML page that features four divs. Each div contains three input fields and a button. The problem arises when a user leaves a text box empty upon submitting - instead of staying in the same div, they are redirected to a different one. How can I resolve this challenge and also display a warning message to prevent users from proceeding if any textbox is left blank?

Here's the code snippet:

<div class="col-sm-12">          
                  <label> <i class="fa fa-paper-plane px-2"> </i> Send To Address</label>
                  <div class="form-group">
                    <input type="text" id="a1" class="form-control" placeholder="Address">
                  </div>
                  </div>      
                 <div class="col-sm-12">          
                  <label style="width: 100% !important"> <i class="fa fa-money px-2"> </i> Amount <span class="pull-right"> Max Amount: --- </span></label>
                  <div class="form-group">
                    <input type="text" id="x1"class="form-control" placeholder="Enter the Amount">
                  </div>
                  </div> 
                  <div class="col-sm-12 text-right">
                  <span class="btn btn-sm btn-info btn1" id="b1"> <small> Continue </small> </span>      
                  </div>          
                      </div>
                </div>
                <div class="tab-pane t2" id="account">
                  <h5 class="info-text"> </h5>
                  <div class="row justify-content-center">

              <div class="col-sm-12">          
              <label> <i class="fa fa-paper-plane px-2"> </i> Send To Address</label>
              <div class="form-group">
                <input type="text" class="form-control" value="Address" disabled>
              </div>
              </div>      
             <div class="col-sm-12">          
             <label style="width: 100% !important"> <i class="fa fa-money px-2"> </i> Amount <span class="pull-right"> Max Amount: --- </span></label>
              <div class="form-group">
                <input type="text" class="form-control" value="Amount Entered" disabled>
              </div>
              </div> 

The jQuery script for handling this scenario:

$(document).ready(function(){
       $('#b1').click(function(){
            if ($('input#a1#x1').val() == ""){
                alert('Please complete the field');
            }
        });
    });

Despite my attempts, all solutions so far only display the warning without halting the redirection. Your assistance would be greatly appreciated!

Answer №1

I noticed in your code that it passes validation even when there is whitespace, so it would be beneficial to use the trim method in your code.

For example:

$.trim($('#a1').val())

The reason I suggest putting the entire statement in $.trim is because previously, calling .trim() on a value caused issues in IE7.

Another important aspect is focusing in jQuery. For instance, if you want to focus on an input tag, simply use:

$("#a1").focus();

The naming convention being utilized does not appear to be user-friendly. It's recommended to name elements in a way that makes the code easier to understand.

Answer №2

The important concept to remember here is "focus". Your goal is to maintain keyboard focus on a specific input field (textbox).

To achieve this, you can simply utilize jQuery's focus() function to direct the keyboard focus towards a particular input field.

It is essential to exercise caution when implementing this technique. Users may navigate through input fields in an unexpected order, such as referencing information from a physical document and entering data accordingly. Abruptly shifting the keyboard focus can potentially complicate navigation on your website, so it is advisable to be mindful of when and where you set the focus.
