    jQuery Text Colour Change Help

    Hi All,

    I have columns of text that start out with the color black, but you have an option to change the color.

    I have done my jQuery code to change color when you press a blue, red or black button but the code is quite long.
    Does anyone know how I can reduce it?

    It is as follows:

    Code:
    $(document).ready(function(){		
    		$("#bluesquare1").click(function(){
    			$("#textblocka").css({"color":"blue"});
    		});	
    		$("#redsquare1").click(function(){
    			$("#textblocka").css({"color":"red"});
    		});	
    		$("#blacksquare1").click(function(){
    			$("#textblocka").css({"color":"black"});
    		});	
    		$("#bluesquare2").click(function(){
    			$("#textblockb, a").css({"color":"blue"});
    		});	
    		$("#redsquare2").click(function(){
    			$("#textblockb, a").css({"color":"red"});
    		});	
    		
    		$("#blacksquare2").click(function(){
    			$("#textblockb, a").css({"color":"black"});
    		});	
    		$("#bluesquare3").click(function(){
    			$("#textblockc").css({"color":"blue"});
    		});	
    		$("#redsquare3").click(function(){
    			$("#textblockc").css({"color":"red"});
    		});	
    		$("#blacksquare3").click(function(){
    			$("#textblockc").css({"color":"black"});
    		});	
    		
    		
    	});
    The div in my code is this:

    Code:
    <div id = "blacksquare1"></div>
    <div id = "redsquare1"></div>
    <div id = "bluesquare1"></div>

    dummy=(tblock_num=='2')?', a':'';
    $('#textblock'+tblock_num+dummy).css('color',col);
    });
    
    });
