Submit form using tag

Question

I am trying to submit a form through onclick event on tag. I have tried triggering document.myform.submit(), this.form.submit(), parentNode.submit() etc. but none of this is working! Using a submit button, the code works fine. But I want to use tag in place of that. Need some help.

            <form id="myform" name="myform" method="POST" action="process_edit_questionnaire.php?project=<?php echo $project_id; ?>">
                <input name="module" type="hidden" value="<?php echo $module_id;?>"/>
                <input name="project" type="hidden" value="<?php echo $project_id;?>"/>
                <input name="hidden_ques_id" type="hidden" value="<?php echo $data_array_ques[$j]['ques_id'];?>"/>

            <div id="question_block">

                <div id="serial_block">
                    <p id="s_original_<?php echo $j+1; ?>"><a href="#" onclick="showSelectBox(<?php echo $j+1; ?>)">Serial : 
                        <?php 
                        if($data_array_ques[$j]['ques_position']==NULL){ 
                            echo $j+1;                            
                        } 
                        else { 
                            echo $data_array_ques[$j]['ques_position'];         
                        } ?></a></p>
                    <p id="s_select_box_<?php echo $j+1; ?>" style="display: none;">Serial : 
                        <select name="serial">
                          <?php for($p=1;$p<=count($data_array_ques);$p++){ ?>
                                    <option value="<?php echo $p; ?>" <?php if($p==$data_array_ques[$j]['ques_position']){ echo "selected=\"selected\"";} ?> ><?php echo $p; ?></option>
                          <?php }  ?>
                        </select>
                    </p>
                </div>

                <div id="question_text">
                    <a href="#" onclick="showTextBox(<?php echo $j+1; ?>)"><p id="q_original_<?php echo $j+1; ?>"><?php echo $data_array_ques[$j]['ques_text']; ?></p></a>
                    <p id="q_text_box_<?php echo $j+1; ?>" style="display:none;"><textarea id="ques_text" name="ques_text" rows="3" cols="30"><?php echo $data_array_ques[$j]['ques_text']; ?></textarea></p>                     
                </div>

            </div>

            <div id="menu_block">
                <a href="" onclick="document.myform.submit()">Save Changes</a> |
                <a href="delete_question.php?project=<?php echo $project_id; ?>&module=<?php echo $module_id; ?>">Delete This Question</a>
            </div>
            </form>

Answer 1

Try this:

Suppose HTML like this :

   <form id="myform" name="myform" method="POST" action="process_edit_questionnaire.php?project=<?php echo $project_id; ?>">
      <div id="question_block">
            testing form
        </div>
     <a href="javascript: submit();">Submit</a>
        </form>

JS :

   <script type='text/javascript'>
     function submit()
      {
         document.forms["myform"].submit();
      }
   </script>

Answer 2

Here is how I would do it using vanilla JS

<form id="myform" method="POST" action="xxx">
    <!-- your stuff here -->
    <a href="javascript:void()" onclick="document.getElementById('myform').submit();>Ponies await!</a>
</form>

You can play with the return falses and href="#" vs void and whatever you need to but this method worked for me in Chrome 18, IE 9 and Firefox 14 and the rest depends on your javascript mostly.
