"Discover the magic of jQuery: Unveiling the hidden div with one simple CSS visibility change

I want to implement a functionality on my screen where the Previous button is hidden initially and only becomes visible when the user clicks the Next button. I have set the CSS property for the Previous button to hide it by default, but despite using an if statement to check if the page counter is greater than 1, the visibility is not changing as intended. Can anyone help me figure out what I am doing wrong?

$(function() {
  $("#navigationButtonTop").css("visibility", "visible");
});

div.navigationButtonTop {
  visibility: hidden;
  height: 100px;
  width: 100px;
  background-color:blue;
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<div class="navigationButtonTop"></div>

javascript jquery html css

Answer №1

Initially, make sure to properly close your if statement and remember that navigationButtonTop is a class and not an id. Here is the corrected code:

if (that.get("pageCounter") >= 1) {
     $(".navigationButtonTop").css("visibility", "visible");
}

After the OP's question update, the revised answer would now be:

$(function() {
  $(".navigationButtonTop").css("visibility", "visible");
});

One thing to consider is how the event is being triggered in your code. It's important to understand if the trigger is actually working properly or not.

Additionally, there seems to be a discrepancy in how you are referencing the element. In CSS, navigationButtonTop is identified as a class using "." while in JS it is identified as an id using "#". This could potentially be causing issues in your current code. If this is not the issue, then it may be something else...

To improve readability, it might be beneficial to create a separate hidden class for setting visibility to hidden. This way, you can simply use:

$("#navigationButtonBottom").on('click', function() {
  $("#navigationButtonTop").removeClass('hidden');
});

Don't forget to add the class hidden to your button in the HTML:

#navigationButtonTop.hidden {visibility:hidden;}

Alternatively, you can achieve the same result using JavaScript:

jQuery(document).ready(function($) {
  $("#navigationButtonTop").addClass('hidden');
})

Remember to always use the "#" sign before a selector's name in both your JS and CSS files for consistency.

Consistency is key - stick with either "#" or dot for both cases.

I've come across a useful jQuery tool that proved to be a lifesaver while customizing Materialize's collapsible feature. It helped me replace the usual click event with a more efficient visibilityChanged event.

The code snippet used (out of various options provided on the plugin page) was as follows:

HTML

<li id="collapsible_trigger">
    <div class="collapsible-header"></div>
    <div class="collapsible-body"></div>
</li>

<script type="text/javascript" charset="utf-8" src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.6.0/jquery.min.js"></script>
<script type="text/javascript" charset="utf-8" src="hideshow.min.js"></script>

JS

$("#collapsible_trigger .collapsible-body").hideShow();
$("#collapsible_trigger .collapsible-body").on("visibilityChanged", function(event, visibility){
    /* Add your customized code here */
});
