Use onSubmit-not sure how?

Copy linkTweet thisAlerts:
Feb 04.2004

This is my form elements.

<table border>
<tr>
<td align=center>Windows:</td>
<td align=center><input type=”text” name=”winnum”>
<td align=center>Linux:</td>
<td align=center><input type=”text” name=”linuxnum” size=”5″ “>
</table>

Upon onSubmit, it should check that:
1.winnum and linuxnum is not null.If any of it is null, it will not submit
2.Submit will only occur if linuxnum + winnum is equals say 4.

How can I do this> Hope some one can help.
I am new at this.
Thanks a lot

<td align=center>Windows:</td>

<td align=center><input type="text" name="winnum">

<td align=center>Linux:</td>

<td align=center><input type="text" name="linuxnum" size="5" ">

</form>

<script language="javascript">

function Validate(frm){

if(frm.winnum.value=="" || frm.linuxnum.value=="){

return true;

} else {

return false;

}

}

</script>


That should do what you want ?

@james_cwyauthorFeb 04.2004 — What about the second part:

2.Submit will only occur if linuxnum + winnum is equals say 4. (Need to check here also) if not equals 4 it will not submit

How can I do this?Thanks

@StevilFeb 04.2004 — <script language="javascript">

function Validate(frm){

//Checks Values Are There

if(frm.winnum.value=="" || frm.linuxnum.value=="){

return true;

}

//Checks Addition Of Values

if(frm.winnum.value + frm.linuxnum.value==4){

return true;

}

return false;

}

</script>


Sorry, missed that part ?

@james_cwyauthorFeb 04.2004 — Tried it but is not working

Shouldn't it be the other way around.

if both text is null, it will not submit-buit why return true?
Copy linkTweet thisAlerts:
@james_cwyauthorFeb 04.2004 — //Checks Addition Of Values

if(frm.winnum.value + frm.linuxnum.value==4){

return true;

}

return false;

}

Tried this part but not working, any ideas?
Copy linkTweet thisAlerts:
@james_cwyauthorFeb 04.2004 — This is the script :

function Validate(frm){

//this part OK

if(frm.winnum.value == "" || frm.linuxnum.value == ""){

alert ("Cannot be Null");

return false;

}

//not sure if this is right

if(frm.winnum.value + frm.linuxnum.value != 4){

alert ("Total number not equal to number of IPs");

return false;

}

//not sure if this is right

if(frm.winnum.value + frm.linuxnum.value == incount)

return true;

} //close function

Am I missing something or doing something wrong?

Hope someone can point it out.

I want it to return true only when frm.winnum.value + frm.linuxnum.value is equals say 4
