    Sum of 2 fields in a label

    Hi developers,

    I am trying to sum the entered prices in 2 fields so the sum will be displayed at a label.

    I have already the code for the fields and the label but I dont know how I can do this in javascript, because I want a realtime calculation, so it will sum everytime you change the prices.

    My code:

    Code:
    SO I WANT TO SHOW THE SUM("proprty_price" AND "proprty_extra_price") OF THE PRICES INTO THE "proprty_total_price_label" LABEL . 
    <div class="form_row clearfix">
                 	<label><?php _e(PRO_PRICE_TEXT); if(get_currency_sym()){ echo " (".get_currency_sym().")";}?> <span>*</span></label>
                 	<input type="text" name="proprty_price" id="proprty_price" class="textfield" value="<?php echo esc_attr(stripslashes($proprty_price)); ?>" />
    				<span class="message_error2" id="proprty_price_span"></span>
                 </div>    
                 
                 <div class="form_row clearfix">
                 	<label><?php _e(PRO_EXTRA_PRICE_TEXT);?> <span>*</span> </label>
                 	<input type="text" name="proprty_extra_price" id="proprty_extra_price" class="textfield" value="<?php echo esc_attr(stripslashes($proprty_extra_price)); ?>" />
    				<span class="message_error2" id="proprty_zip_span"></span>
                 </div>
                			
    			 <div class="form_row clearfix">
                 <label id="proprty_total_price_label"><?php _e(PRO_TOTAL_PRICE_TEXT);?> <span>*</span> </label>
                  </div>
    Thank you in advance,

    Basically attach even handlers to the input elements that will run a function that will add up the total and then place the total in the label.
    Code:
    window.onload = function()
    {
    	if (document.getElementById('proprty_price').attachEvent)	//for IE8 and older
    	{
    		document.getElementById('proprty_price').attachEvent('onkeyup', GetTotal);
    		document.getElementById('proprty_extra_price').attachEvent('onkeyup', GetTotal);
    	}
    	else 								// most other browsers, also works in IE9
    	{
    		document.getElementById('proprty_price').addEventListener('keyup', GetTotal, false);
    		document.getElementById('proprty_extra_price').addEventListener('keyup', GetTotal, false);
    	}
    }
    
    function GetTotal()
    {
    	var total = parseInt(document.getElementById('proprty_price').value) + parseInt(document.getElementById('proprty_extra_price').value);
    
    	document.getElementById('proprty_total_price_label').innerHTML = total;
    }
    The "parseInt" may not be needed but If I recall correctly the values of the input field will be a handled as strings so they need to be converted to integers to perform the addition.

    I don't normally type out the whole code but I hope it helps.

    Yes it works! But somehow it causes problems with my map on the same page :S Maybe because it also uses javascript?

    this is the code of the map in the same page:
    [CODE]
    div class="form_row clearfix">
    <?php require_once (TEMPLATEPATH . '/library/map/location_add_map.php');?>
    </div>
    [/CODE?

    and the external file of the map:
    Code:
    <?php /*?><input type="text" name="address" id="address" value="1600 Amphitheatre Pky, Mountain View, CA" size="50" /><?php */?>
    <script type="text/javascript">
    	/* <![CDATA[ */
    function get_address()
    {
    	var proprty_address=document.getElementById('proprty_address').value;
    	var proprty_city=document.getElementById('proprty_city').value;
    	var proprty_state=document.getElementById('proprty_state').value;
    	var proprty_country=document.getElementById('proprty_country').value;
    	var proprty_zip=document.getElementById('proprty_zip').value;
    	var address = '';
    	if(proprty_address!='')
    	{
    		address = address+proprty_address;
    	}
    	if(proprty_city!='')
    	{a
    		if(address)
    		{
    			address = address+','+proprty_city;	
    		}else
    		{
    			address = address+proprty_city;
    		}
    	}
    	if(proprty_state!='')
    	{
    		if(address)
    		{
    			address = address+','+proprty_state;	
    		}else
    		{
    			address = address+proprty_state;
    		}
    	}
    	if(proprty_country!='')
    	{
    		if(address)
    		{
    			address = address+','+proprty_country;	
    		}else
    		{
    			address = address+proprty_country;
    		}
    	}
    	if(proprty_zip!='')
    	{
    		if(address)
    		{
    			address = address+','+proprty_zip;	
    		}else
    		{
    			address = address+proprty_zip;
    		}
    	}
    	return address;
    }
    /* ]]> */
    </script>
    <input type="button" class="btn_input_normal btn_spacer" value="<?php _e('Set Address on Map');?>" onclick="findAddress(get_address());" />
    <div id="map_canvas" style="float:right;
    height:300px;
    margin-right:36px;
    position:relative;
    width:410px;"  class="form_row clearfix"></div>
    Do you maybe know whats causes the problem?

    Thank you so much for your help,
    Engin
