JavaScript元素样式随动态ID而变化

I am trying to put a line through a list item when the check box next to it is checked. I have managed to do it but I can't check if the the box is checked.

JS File

    if(document.getElementById(theID).checked){

document.getElementById(theID).setAttribute("style", "text-decoration:line-through");
}

HTML/PHP

                echo'<ol>';
            foreach($to_do_XML->task as $item)
            {
                $theID = $item['id'];

            echo '<li id="'.$theID.'">'.$item.'</li>' ;?><form ><input  onclick="return cross('<?=$theID?>');" type="checkbox" name="done<?php $li_id_num_done ?>"/></form>
                 <?php     

            }
            echo '</ol>';

i should also add that the list item is being added within a foreach loop looping trough xml elements

The above code does nothing any help would be appreciated

    If $theID is a string, you need quotes around it:

         <input  onclick="return cross('<?php echo $theID; ?>');" type="checkbox" name="done<?php $li_id_num_done ?>"/>
    

    Also remove this from your function:

    got_elements_id
    

    It will cause a reference error.
