Question

Number of form fields with same name query

Hi there,

I've written a script to add checkboxes to a page and the code works ok.

I'm in the process of putting some error handling in however I've hit a slight niggle.

If I use the following to reference a formfield by name is there a quick way to check if there's more than one field with the same name?

thisField = this.getField(theBaseFieldName);

I thought I might be able to check thisField.length to see if it's greater than 1 but unfortunately not. I guessing it's because of the way I'm refering the object. Please can someone point me in the right direction?

Thanks in advance.

Hi there,

Please can someone point me in the right direction.

The code below doesn't work, or works intermittenly, yet I have verified there is only 1 form field with the name 'ewq'.

var theBaseField = 'ewq';
var thisField = this.getField(theBaseField);
var fieldsNum = thisField.page.length;
//app.alert(fieldsNum)


if (numFields==1) {
    app.alert('Message-1')
} else {
    app.alert('Message-2')
}

If I un-comment app.alert(fieldsNum) I get an undefined error yet the field is there on the page?

Could it be that a persistent session variable is causing the issue?

 

Thanks in advance.

You have not set the variable numFields?

Thanks Bernd.

I'd been changing variable names, didn't spot that!

Check the property page of the field.

Hi Bernd,

Thanks for your reply.

 

I'm not sure if I explained things correctly.

All I'm trying to do is find out how many checkboxes there are with the name 'xyz123'.

If the count is greater than 1 then I need to catch that.

Is it a case of looping through all the form fields in the document and check the name of each one?

 

Thanks Bernd
