Re: Check/Uncheck all checkbox

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Try something like this:

        <script type='text/javascript'>
        <!--
            function MyCheck(ctrlCheck, checkListName)
            {
                var chBoxes = document.getElementsByName(checkListName);
                for (i = 0; i < chBoxes.length; i++)
                    chBoxes[i].checked = ctrlCheck.checked ;
            }
        //  -->
        </script>


        <form>
            <input type="checkbox" name="Check_ ctr" value="yes" onClick="MyCheck(this, 'check_list[]')" /><b> Check Control</b>
            <br /><br />
            <input type="checkbox" name="check_list[]" value="3"/>hello1<br>
            <input type="checkbox" name="check_list[]" value="4"/>hello2<br>
            <input type="checkbox" name="check_list[]" value="5"/>hello3<br>
        </form>        



In this case I pass two parameters to the JS function:
1.- The Control CheckBox
2.- The NAME of the CheckBoxes I want to check/uncheck uppon clicking the control box.

Hope this helps

 I know this is not the appropriate list for this question, but I was just
 wondering if there's anyone in this list that can help me out here...
 
 I want a checkbox that checks/unchecks all the other checkbox below it....
 the following code works fine.... but If I replace the name of the
 checkbox as an array (i.e. from 'check_list' to 'check_list[]' ) it doesnt
 work....
 I would really appreciate if anyone can help me out...
 
 Here is my code:
 
 ====================================================================
 ====================================================================
 <script language="javascript">
 <!--
 
 function MyCheck(chk)
 {
 if(document.myform3.Check_ctr.checked==true){
 for (i = 0; i < chk.length; i++)
  chk[i].checked = true ;
 }else{
 
 for (i = 0; i < chk.length; i++)
  chk[i].checked = false ;
 }
 }
 
 //  End -->
 </script>
 
 <form name="myform3" action="checkboxes.asp" method="post">
 <input type="checkbox" name="Check_ctr" value="yes"
 onClick="MyCheck(document.myform3.check_list)"><b>Check Control</b>
 <br /><br />
 <input type="checkbox" name="check_list" value="3">hello1<br>
 <input type="checkbox" name="check_list" value="4">hello2<br>
 <input type="checkbox" name="check_list" value="5">hello3<br>
 
 </form>
 
 =====================================================================
