Show/Hide Section

Question

Show/Hide Section

I am struggling to implement two buttons - one for expanding a div and one for collapsing it. Despite multiple attempts to modify the code, I have not been successful. It appears that I am having trouble understanding how to prevent a link from toggling.

Additionally, I want the DIV to be visible when the page loads. I am uncertain if this can be achieved with my current coding approach.

If anyone can provide guidance on what steps I need to take to make this functionality work, I would greatly appreciate it.

http://jsfiddle.net/XUjAH/93/

I am aiming to avoid using .slideUp/.slideDown as they appear to be conflicting with another plugin on the page.

  $('#click-meopen').click(function() {
    var height = $("#this").height();
    if( height > 0 ) {
        $('#this').css('height','0');
    } else {
        $("#this").css({'position':'absolute','visibility':'hidden','height':'auto'});
        var newHeight = $("#this").height();
        $("#this").css({'position':'static','visibility':'visible','height':'0'});
        $('#this').css('height',newHeight + 'px');
    }
});

$('#click-meclose').click(function() {
    var height = $("#this").height();
    if( height > 0 ) {
        $('#this').css('height','0');
    } else {
        $("#this").css({'position':'absolute','visibility':'hidden','height':'auto'});
        var newHeight = $("#this").height();
        $("#this").css({'position':'static','visibility':'visible','height':'0'});
        $('#this').css('height',newHeight + 'px');
    }
});

Check out an example I created here - http://jsfiddle.net/XUjAH/99/

Here is the HTML code snippet:

<p id="click-meopen">click me to open</p>
<p id="click-meclose">click me to close</p>
<div id="this">
    <div id="content">here<br />is<br />a<br />bunch<br />of<br />content<br />sdf</div>
</div>

As for the JavaScript code:

$('#click-meopen').click(function() {
    $("#this").height($("#content").height());
});
$('#click-meopen').click();

$('#click-meclose').click(function() {
    $("#this").height('0');
});

The CSS should remain the same as what you already have.

Update: There seems to be a slight issue with the animation - setting 'height: auto' makes the div visible from the start, but the close button doesn't animate properly on the first click (I'm using Chrome with the latest update). I've made some adjustments to address this. I've also added additional styles to support the animation in other browsers like Firefox and Opera, not just those that support -webkit.

Check out the updated version here: http://jsfiddle.net/XUjAH/110/

In the CSS, I added a class and removed 'transition' from the main style:

.with-animation {
    -webkit-transition: height 1s ease-in-out;
    -moz-transition: height 1s ease-in-out;
    -o-transition: height 1s ease-in-out;
    transition: height 1s ease-in-out;
}

In the JavaScript: // Despite the div already having the correct size, this line // prevents an instant close on the first click, the reason is unknown $("#container").height($("#content").height());

$('#click-meopen').click(function() {
    $("#container").height($("#content").height()); 
});

$('#click-meclose').click(function() {
    // Adding the class with-animation to the upper level div will
    // initiate the animation on page load
    $("#container").height('0').addClass("with-animation");
});

If the `toggle` function is available to you, a simple solution is to use `$("#this").toggle('slow');`, however, ensure to substitute `height: 0;` with `display: none;`

Are you looking to convert this into buttons?

<input type="submit" id="click-meopen" value="open"></input>
<input type="submit" id="click-meclose" value="close"></input>
<div id="this">here<br />is<br />a<br />bunch<br />of<br />content<br />sdf</div>

It's not a difficult task to accomplish.

I would suggest utilizing .toggle() or the .show(),.hide() methods from jQuery. Simply adjusting the css height property to zero may not be ideal.

Would you like the div to be displayed when the page loads or when the DOM is fully loaded?

Your JavaScript code would look like this:

$('#click-meopen').click(function() {
    $('#this').show(); // or .toggle()
});

$('#click-meclose').click(function() {
    $('#this').hide(); // or .toggle()
});

If you are using only one button, the .toggle() method is recommended. Otherwise, stick with the .show(),.hide() method!

For when the DOM is fully loaded:

$(document).ready(function(){
     $('#this').show();
});

Answer №5

Upon reviewing your code, I noticed that you have utilized the -webkit-transition property, which functions well in Chrome. However, if your objective is to make it compatible with browsers other than Webkit, I have a couple of recommendations.

Firstly, you can simply incorporate

-moz-transition: height 1s ease-in-out;

and

transition: height 1s ease-in-out;

in your CSS code to utilize CSS3. Please note that this approach may not be effective in older versions of Internet Explorer.

Alternatively, you can nest a div within the div you wish to collapse:

<div id="this">
    <div id="height">
         text
         text
     </div>
</div>

Subsequently, in your JavaScript, you can fetch the height of the inner div element and employ the animate function instead of setting the height to auto.

$('#click-meopen').click(function() {
    $('#this').animate({'height': $('#height').height()}, 1000);
});

$('#click-meclose').click(function() {
    $('#this').animate({'height': 0}, 1000);
});

These adjustments should address your needs.
