Resolved Adding & removing a div class when a checkbox is clicked/unclicked

inchecksolution · 08-11-2011, 02:03 AM

Hi guys. I have a lot of information on my site that is in multiple categories. I have a list of categories, each with its own checkbox. By default, all the information is displayed (therefore all the checkbox's are checked by default).

When someone unchecks the box I want to hide the divs with that class, and when someone rechecks the box, they should reappear. Here is my code so far. It is hiding the div's fine, but they are not reappearing when user tics the checkbox again.

Code:

<script type="text/javascript">
function toggledisplay(category){
	if(document.getElementById(category).checked){
		$("."+category).removeClass(category+"-hidden").addClass(category);	
	}
	else{
		$("."+category).addClass(category+"-hidden").removeClass(category);		
	}
}
</script>

<input type="checkbox" checked="checked" name="fitness" id="fitness" onclick="toggledisplay('fitness')" />

Maybe use this demo as a guide.

Code:

<html xmlns="http://www.w3.org/1999/xhtml">

        <title></title>
        <style type="text/css">
        </style>
        <script type="text/javascript">
            function showHideDivs(obj) {
                var infoDivsO = obj.parentNode.getElementsByTagName('div');
                var dispStatus = (obj.checked)? 'block' : 'none';
                for(i=0; i < infoDivsO.length; i++){
                    infoDivsO[i].style.display = dispStatus
                }
            }
            window.onload=function(){
                var chkCatO = document.getElementsByClassName('chkCat');
                for(i=0; i < chkCatO.length; i++){
                    chkCatO[i].onclick = function(){
                        showHideDivs(this);
                    }
                }
            }
        </script>
    </head>
    <body>
        <div>
            <input class="chkCat" type="checkbox" checked="checked"/> Category 1
            <div> cat 1 div 1</div>
            <div> cat 1 div 2</div>
        </div>
        <div>
            <input class="chkCat" type="checkbox" checked="checked"/> Category 2
            <div> cat 2 div 1</div>
            <div> cat 2 div 2</div>
            <div> cat 2 div 3</div>
        </div>
        <div>
            <input class="chkCat" type="checkbox" checked="checked"/> Category 3
            <div> cat 3 div 1</div>
        </div>
    </body>
</html>

Actually, I found the answer...dumb mistake.

If something is hidden the current class is category+"-hidden". but I was still just searching for "."+category.

FIXED:

Code:

function toggledisplay(chk, category){
	if(chk.checked == 1){
		$("."+category+"-hidden").removeClass(category+"-hidden").addClass(category);
	}
	else{
		$("."+category).addClass(category+"-hidden").removeClass(category);		
	}
}
