    Red face [SOLVED]Unchecked check box parameter is not submitted when a form is submitted

    [SOLVED]Unchecked check box parameter is not submitted when a form is submitted


    Hi all,

    I'm working on a form with checkbox, when I submitted the form, I found that the checkbox parameter is missing in the request parameter list when the checkbox is bot checked.

    Then I checked the form.getValues() method, this method also is not giving the parameter when the check box is not checked.

    When I went into the source code it is taking me to YAHOO.util.Connect.setForm(), there I found the following piece of code

    switch (oElement.type){
    ---------------
    ---------------
    case 'checkbox':
    if(oElement.checked){
    this._sFormData += encodeURIComponent(oName) + '=' + encodeURIComponent(oValue) + '&';
    }
    break;
    ---------------------
    --------------------
    }

    Can any one tell me why the check box value is not attached to the formData if it is not checked? What is the logic behind it? And What should I do to get the value of a unchecked chechbox?

    Thank you
