Hide/show - view checkboxes to <a> links

Hey,

I have a Google Map section on my site with 3 categories:

- Alpine
- Nordic
- Tubing

Right now they all have say 10 markers for each category. And are currently can be hide/show via a checkbox. I am looking to move it to something like:

 
<div class="marker_legend">
	<ul>	
		<li><a href="#alpine"><span><img width="12" height="20" style="margin-bottom:-6px;" alt="" src="http://localhost:8888/ski/wp-content/themes/images/googlepins/blue_Marker.png"> Alpine</span></a></li>
		<li><a href="#nordic"><span><img width="12" height="20" style="margin-bottom:-6px;" alt="" src="http://localhost:8888/ski/wp-content/themes/images/googlepins/red_Marker.png"> Nordic</span></a></li>
		<li><a href="#tubing"><span><img width="12" height="20" style="margin-bottom:-6px;" alt="" src="http://localhost:8888/ski/wp-content/themes/images/googlepins/green_Marker.png"> Tubing</span></a></li>
		
	</ul>
</div>

Open in new window


Another developer coded this section for the checkboxes:

 
function hideOrShowPins(whoToShow,whichBox){
	
	for (i=0;i<markers.length;i++ ){
			if(markers[i][1]==whoToShow  && whichBox.checked == false){
				markers[i][0].hide();
			}else if(markers[i][1]==whoToShow){
				markers[i][0].show();
			}
		}

}

Open in new window


And lastly, the output of the checkboxs looks something like:

<input type="checkbox" onclick="hideOrShowPins('alpine',this);" checked="checked" value="alp" name="al">

Open in new window


What would be the best way do this using <a> not the checkboxes?

Thanks!

Ryan

Simply this? (if the javascript was working already :) )
<a href="javascript:hideOrShowPins('alpine',this);" name="al" id="al">Toggle</a>

I tried that, thought it would be that simple :)

The code is checking for checked true/false. Guessing that is why its not firing?

    	function hideOrShowPins(whoToShow,whichBox){
    		
			for (i=0;i<markers.length;i++ ){
 				if(markers[i][1]==whoToShow  && whichBox.checked == false){
 					markers[i][0].hide();
 				}else if(markers[i][1]==whoToShow){
 					markers[i][0].show();
 				}
 			}
    	
    	}

rather than checking for check/uncheck....look for the caption of the anchor
update it to

function hideOrShowPins(whoToShow,whichBox)
{    		
	for (i=0;i<markers.length;i++ )
        {
 		if(markers[i][1]==whoToShow  && whichBox.html() == "hide")
                {
                         whichBox.html("show") ;
 		         markers[i][0].hide();
 		}
               else if(markers[i][1]==whoToShow)
                {
                         whichBox.html("hide") ;
 			markers[i][0].show();
 		}
 	}	
}

<a href="javascript:hideOrShowPins('alpine',this);" name="al" id="al">show</a>

Hey, no go on that. The only limitation is the output of that is from the google map API. A marker looks like:

<img style="width: 20px; height: 34px; -moz-user-select: none; border: 0px none; padding: 0px; margin: 0px; position: absolute; left: 295px; top: 220px; z-index: -144372608; cursor: pointer;" src="http://localhost:8888/ski/wp-content/themes/ski-maine/images/googlepins/blue_MarkerA.png" id="mtgt_unnamed_0">

Open in new window


I also tried that code on a onclick event

Here is an example of how it works now: http://goo.gl/srIOP - at the bottom right are the checkboxes. That same behavior but im trying to get the toggle on the link instead.

This is what I have for my <a>

					<li><a href="javascript:hideOrShowPins('alpine',this);" id="al" name="al"><span><img src="<?php bloginfo( 'template_url' ); ?>/images/googlepins/blue_Marker.png" alt="" width="12" height="20" style="margin-bottom:-6px;"/> Alpine</span></a></li>

Not sure how above code matters.

In that hideOrShowPins(), where is the marker array taken from? what are its values?

Looking through it again, I think i would be better usability wise and code to attach it to the code you worked on before: http://jsfiddle.net/nhDxH/7/

So say you click Alpine (in the accordion) you would see ONLY the Alpine markers. If you click the Nordic header in the accordion you'll only see the Nordic markers.

The checkbox code to fire that function posted in my question at the top looks like:

<div id="toggle_markers">
	<div class="alp">
		<input name="al" type="checkbox" value="alp" checked="checked" onclick="hideOrShowPins('alpine',this);"/>&nbsp; Alpine
	</div>
	<div class="alp">
		<input name="no" type="checkbox" value="no" checked="checked" onclick="hideOrShowPins('nordic',this);" />
		&nbsp; Nordic
	</div>
	<div class="alp">
		<input name="tu" type="checkbox" value="tu" checked="checked" onclick="hideOrShowPins('tubing',this);" />
		&nbsp; Tubing
	</div>
</div>

That said we can find out HOW it is getting ALL alpine markers and $(XXX).hide(); to hide them all.
