form validation problems

[meenakshia]

hi forum
i have been trying to use a way to validate my form but i was unable to use it properly
pls rectify my mistakes.

i m using input type as a button and calling a function to save the form data.
now i want to check if all fields are entered properly before submitting the form

the javascript function i m using is

<script language="JavaScript">
function formCheck(formobj){
    // Enter name of mandatory fields
    var fieldRequired = Array("txtddate", "txtspid");
    // Enter field description to appear in the dialog box
    var fieldDescription = Array("Delivery Date", "Sales Person Name");
    // dialog message
    var alertMsg = "Please complete the following fields:\n";
 
    var l_Msg = alertMsg.length;
 
    for (var i = 0; i < fieldRequired.length; i++){
        var obj = formobj.elements[fieldRequired[i]];
        if (obj){
            switch(obj.type){
            case "select-one":
                if (obj.selectedIndex == -1 || obj.options[obj.selectedIndex].text == ""){
                    alertMsg += " - " + fieldDescription[i] + "\n";
                }
                break;
            case "select-multiple":
                if (obj.selectedIndex == -1){
                    alertMsg += " - " + fieldDescription[i] + "\n";
                }
                break;
            case "text":
            case "textarea":
                if (obj.value == "" || obj.value == null){
                    alertMsg += " - " + fieldDescription[i] + "\n";
                }
                break;
            default:
            }
            if (obj.type == undefined){
                var blnchecked = false;
                for (var j = 0; j < obj.length; j++){
                    if (obj[j].checked){
                        blnchecked = true;
                    }
                }
                if (!blnchecked){
                    alertMsg += " - " + fieldDescription[i] + "\n";
                }
            }
        }
    }
 
    if (alertMsg.length == l_Msg){
        return true;
    }else{
        alert(alertMsg);
        return false;
    }
}
</script>
 

and form details are

<form name="outputForm1" >
<td>Delivery Date</td>
<td><input type="text" name="txtddate" tabindex="1"  size="20"  ></td>
<td>Sales Person Name</td>
<td><select name="txtspid" tabindex="2">
    <option selected>Pls. Choose</option>

Call the validation function onsubmit:

<form ... onsubmit="return formCheck()">

What does saveForm() do?

[meenakshia]

hi thanks for ur reply
well actually i have posted only a part of the whole code
it is too big
and there are around 10 input fields for which the user has to input the data in
and saveform function saves that data in ms access file(the database)
my problem was that i was not able to use both saveform and form validator which is really important for the working of the whole form
i will try and get back to u if it works fine:)
smile always:)

Does SaveForm() save to a local MS Access file or does it submit to the server?

You can call SaveForm() from within the form validation function if it passes validation.

hi yes it saves the data on local machine.there is no server and yes that is what i m trying to do without success
i m trying to put saveform() inside the validation function but unable to run it:(

OK, make the save button into a submit button and remove the onclick. Add the onsubmit if you haven't already done so. Now in the formCheck() function where you would return true, call SaveForm() instead. To prevent form submission, you should also return false at the end of SaveForm().
