    <p>I have N number of radio button groups in the page with auto generated names.</p> <p>I want to call a javascript function as the value of the checked property. <strong>THIS LINE EXCLUDED AFTER EDIT</strong> ( Depending on the return value, the radio button needs to be checked or unchecked.)</p> <pre><code>&lt;input type="radio" name="auto_generated_name" value="some_value" checked="test_check(args);" /&gt; </code></pre> <p>and the javascript function is</p> <pre><code>function test_check(params) { if(conditions){ return true; } else return false; } </code></pre> <p>But that does not work. Whatever value I assign to 'checked' property, be it any javascript function or any string etc, the radio button becomes checked.</p> <p>How can I achieve my goal?</p> <p>EDIT:</p> <pre><code> &lt;input type="radio" name="auto_generated_name" value="somevalue" onclick="test_check(args)"/&gt; </code></pre> <p>4 radio buttons make a group. such N radio groups have html class names in this way : button_group_1, button_group_2, button_group_3, button_group_4 etc.</p> <p>The 'args' need to be these class (i.e. radio button group) names and the corresponding values (from value="1", value="2", value="3" and value="4" ). </p> <p>Cookies with the class names and values will be created inside the javascript function.</p> <p>On page refresh, cookies matching with the class names will be checked and depending on the existence of the corresponding cookies, the radio button will be checked or unchecked.</p> <p>How to achieve the goals/</p>

    3. CO@erimerturk , when the page is loading, checked="test_check(args)" will trigger the javascript function. If the return value of the function is true, radion button will be checked, if return value is false, it won't be checked. If assigning a js function to 'checked' property is not the expected way, what should be the way?

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.
