JavaScript自动提交表格

Question

I have a form that I need to submit automatically... (the fields are already filled and its complicated to explain why but it IS necessary to do it this way).. I know how to autosubmit the form using Javascript but the only problem I have is that there is more than 1 submit button.. and I need 1 in particular to be submitted... thanks in advance

EDIT2(source):

<I put the javascript in the head... />
<FORM ACTION="PDF.php" name="form" METHOD="post">
<A whole bunch of inputs />
<INPUT TYPE="submit" name="form-save" VALUE="Save Changes" >
<INPUT TYPE="submit" name="form-submit" VALUE="Submit" >
<input type="submit" name="print" id="print" value="Download PDF" />
</form>

Answer 1

$("#yourbuttonid").click();

EDIT:

<form>
    ... 
   <input type="submit" id="myFirstsubmit" /> 
   <input type="submit" id="mysubmit" /> 
</form> 
<script type="text/javascript">  
    $(document).ready(function(){$("#mysubmit").click();}); 
</script>
