How do I check the input field arrays

[Darghon]

I have a form with several tabs, the tabs are all identical but represent data from different environments.

so the text fields have names like date_approved[16] representing the date_approved for environment 16.

 

Now I want to generate input checks for all tabs, so I generate checks like the following, but they don't work, any solutions?

 

//frm is a passed variable that contains the document.form
if(frm.prod_apprby[16].value != "" && frm.prod_dtappr[16].value == ""){
			alert("Env 16: Production Approved by can not be filled in if date approved is blank.");
			return false;
		}

 

Thx in advance

I would HIGHLY suggest using FireFox and FireBug! This combination will help you immensely in troubleshooting and developing your javascript.

document.form is wrong. It should be document.forms.

 

I assume prod_apprby is the form name? If so, frm.prod_apprby[16] doesn't make sense to me. Can you show me the HTML for the form?

[Darghon]

document.form was not what frm stood for,

 

to be more detailed, frm was => document.frmRequest

so frm.prod_apprby[16] was => document.frmRequest.prod_apprby[16]

where "prod_apprby[16]" was the name of a field in the form

 

I managed to solve this with the following statement:

 

document.getElementsByName("prod_apprby[16]")[0].value

 

This would give me the value of that field, and not an undefined error like the previous attempt did.

I don't know why you have brackets like that, but you could have done:

document.forms["formname"]["prod_apprby[16]"].value
