    <p>I have created function for creating a div, when u selet the value in dropdown box , based upon the length the number of divs will be created , so the code is</p> <pre><code>&lt;select onchange="test()" id="selected_opt"&gt; &lt;option value="0" selected&gt;-Select-&lt;/option&gt; &lt;option value="1"&gt;Communication&lt;/option&gt; &lt;option value="2"&gt;XXXXXXXXXXXXX&lt;/option&gt; &lt;/select&gt; </code></pre> <p>the function test is </p> <pre><code>function test(){ var result = get_id.options[get_id.selectedIndex].value; if(result == 1){ var i = 0, c = model_details_json.communication, j = c.length, communications_div = document.getElementById("model_communication"); if(j == 0){ alert('nothing'); } for (; i&lt;j; i++){ var communication = c[i]; var create_div = document.createElement('div'); create_div.id = 'communication_id'+i; create_div.name = 'communication'; var create_anchor = document.createElement('a'); create_anchor.innerHTML = communication.communication_name; communications_div.appendChild(create_div); document.getElementById(create_div.id).appendChild(create_anchor); create_anchor.setAttribute("href", "javascript:void(0);"); create_anchor.setAttribute("onclick","sample('"+communication.communication_name+"','"+create_div.name+"')"); } } </code></pre> <p>for example the length is 6 means the six number of divs will be created , so what the problem is when i again click on communication in select dropdown i.e already the six divs have been created , when do it again then agin six divs are created , so totally 12 divs created when u do it again it goes for 6 multiples....... </p> <p>so what i need is the number of div would not be repeated. and it should be validate whether the user is clicking the same value in dropdown </p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
