Javascript validation for multiple text fields with identical names

[roger_v]

Hello All,

I have a form that has several textboxes with identical names. I figured out a way to validate them by going row by row in the DOM. The problem is that I have a checkbox associated with each row and I need to validate only those rows that are checked and ignore the ones that aren't. Any ideas on how this might be accomplished? thanks,

Here is my validating procedure:


function isValid(){
var isDecimal_re = /^\d+(\.\d+)+$/; //to check for decimal input
var texts=document.getElementsByTagName("input");

columns=4;
for (i=0; i<texts.length; i++)
{
if (texts[i].type=="text")
{
if (!isDecimal_re.test(texts[i].value))
{
columnId=(i%columns)+1;
rowId=Math.ceil(i/columns)+1;
switch(columnId)
{
case 1:
alert("Invalid Number, has to be decimal");
texts[i].focus();
return false;

case 2:
alert("Invalid Number, has to be decimal");
texts[i].focus();
return false;

case 3:
alert("Invalid Number, has to be decimal");
texts[i].focus();
return false;

case 4:
alert("Invalid Number, has to be decimal");
texts[i].focus();
return false;
}
}

}

}
}


I have a checkbox named counter associated with each row and I need to validate only those rows where counter is checked. I tried using the getElementById for the checkbox and see if it is checked but I'm having trouble determining where the end of the row is for that particular checkbox! :confused:

Are the inputs and check boxes dynamically generated? can't you name them like mytest1 mytext2 etc and the checkboxes like chk1 chk2 etc?

Hi,

Yes the input boxes and check boxes names are dynamically generated. I have a textbox_#currentrow# that assigns a unique name to each of these as well as the checkboxes. I'm a noob to Javascript and don't know how I can reference them in the document. thanks,

i don't know the simple code for this validating, but i find a plug-in that you may be need:

try open this one

you can use the same name for your textbox, with different alert. But you need to learn the javscript, how it's work.
good luck:)

Thanks davelf,

Although I'm even more of a noob with jquery than js, I'll give it a shot and see if I can figure a way out to customize it for my app. without spending too much time on it. thanks again,
