Hello experts,
I am trying to find out who is the parent of  "ul li.next-button" for my jquery function to display the "hola"  message. Below you will see snippets of the code. What I am doing wrong?

thanks

Winter

html:

      <div id="cars">
                        <div id="step-1">
                              <div class="headers">
                                    <h2 class="name-photo"></h2>
                              </div>
                              <div id="name-of-form">  
                                    <form action="">  
                                          <fieldset>  
                                                <label id="name_label" for="name_label"></label>  
                                                <input type="text" class="text-input" value="" size="30" id="name-input" name="name">
                                          </fieldset>
                                    </form>
                              </div>
                        </div>
                        <div id="step-2">
                              <div class="headers">
                                    <h2 class="cars brands"></h2>
                              </div>
                              <p class="skip-button"><a href="#">Skip</a></p>
                        </div>
                        <div>
                              <ul>
                                    <li class="back-button"><a href="#">Back</a></li>
                                    <li class="next-button"><a href="#">Next</a></li>
                              </ul>      
                        </div>
                  </div>

Jquery part:

$(document).ready(function () {                  
                  $('ul li.next-button').click(function () {
                        if ($(this).parent().parent().attr('id') == 'step-1') {
                              alert("hola!!");
                        }
                  });
});

Thanksagain

Hi Leakim971,

Could you please explaing me a little better?
you mean that I would have to do something like:

$(document).ready(function () {                  
                  $('ul li.next-button').click(function () {
                        if ($(this).parents().attr('id') == 'step-1') {
                              alert("hola!!");
                        }
                  });
});

Actually, I think I was the one who did not explain clear, I am trying to reach "step-1" from "next-button". so, how many levels up I need to go to reach it?

Please let me know if I was clear. Sorry about my first question that was not clear.

don't have sense with "id", but if we have :




<div id="step-1" class="mytopdiv">

With a good indentation we can find why, div id="step-1" is not a parent div of the ul :


<div id="cars">
    <div id="step-1">
	    <div class="headers">
		    <h2 class="name-photo"></h2>
    	</div>
	    <div id="name-of-form">  
		    <form action="">  
    			<fieldset>  
    				<label id="name_label" for="name_label"></label>  
    				<input type="text" class="text-input" value="" size="30" id="name-input" name="name">
    			</fieldset>
    		</form>
    	</div>
    </div>
    <div id="step-2">
	    <div class="headers">
    		<h2 class="cars brands"></h2>
	    </div>
    	<p class="skip-button"><a href="#">Skip</a></p>
    </div>
    <div>
        <ul>
            <li class="back-button"><a href="#">Back</a></li>
            <li class="next-button"><a href="#">Next</a></li>
        </ul>      
    </div>
</div>

Well done!

To get the div you want, I propose : $(this).parents(".mytopdiv").children(".foreigndiv").eq(0)
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>Untitled Document</title>
<script language="javascript" src="http://code.jquery.com/jquery-1.4.2.min.js">
</script>
<script language="javascript">
	$(document).ready(function () {                  
		$('ul li.next-button').click(function () {
			if($(this).parents(".mytopdiv").children(".foreigndiv").eq(0).attr("id") == 'step-1') {
				alert("hola!!");
			}
		});
	})
</script>
</head>
<body>
<div id="cars" class="mytopdiv">
    <div id="step-1" class="foreigndiv">
	    <div class="headers">
		    <h2 class="name-photo"></h2>
    	</div>
	    <div id="name-of-form">  
		    <form action="">  
    			<fieldset>  
    				<label id="name_label" for="name_label"></label>  
    				<input type="text" class="text-input" value="" size="30" id="name-input" name="name">
    			</fieldset>
    		</form>
    	</div>
    </div>
    <div id="step-2" class="foreigndiv">
	    <div class="headers">
    		<h2 class="cars brands"></h2>
	    </div>
    	<p class="skip-button"><a href="#">Skip</a></p>
    </div>
    <div>
        <ul>
            <li class="back-button"><a href="#">Back</a></li>
            <li class="next-button"><a href="#">Next</a></li>
        </ul>

Thanks both of you. Your solutions worked very well.

I give more points to leakim971 because he made me see what was the real problem : div id="step-1" was not a parent div of the ul. Also, indentation should be something to always keep in, I usually forget that.

Thanks guys!!!
