Element Dependency

Greetings,

As always I am impressed with your work. One thing I was thinking about however were cases which require a form object to possess some sort of property depending on the value of another form object.

For instance, I have several cases where I would like to have "if (this.dropdown.options[this.dropdown.selectedIndex].text == 'myparam' && !this.dependentfield.value) then output generic alert.
I looked at your m key for ideas, but since I am inept at javascript I failed miserably.

I appreciate your help,

cshanek

:(

I just read the Defining Dependencies post to the Tigra Form Validator Pro forum. Apparently there are too many possibilities to code dependencies into this script.

Sorry I keep replying to myself..

It seems as though accomodations could be made to the following code....// check reqired fields
if (this.a_fields[n_key]['r'] && !this.a_fields[n_key]['v']) {
this.a_fields[n_key].n_error = 1;
n_errors_count++;
}

to allow for something like...
'dependent':{'l':Dependent', 'r':true if form.dependee, 'f':'Dependent'}

What do you think?

Last update.

For those of you who wanted to know I was able to impliment a way to allow for validation of dependent form elements.

Here is an example that I used. If my select box purchase was either 'Need to order' or 'Already have', I wanted to validate my textbox Afe to insure it was not null. If the textbox reboot_time wasn't null, I wanted to ensure that my dropdown ampm was not null.

<script language="JavaScript">
var o_fields = {
'reboot_time':{'l':'Time','r':false,'f':'time','t':'v_reboot_time'}
}

//########### validate #############
function validate(f) {

if (f.purchase.options[f.purchase.selectedIndex].text == 'Need to Order' || f.purchase.options[f.purchase.selectedIndex].text == 'Already Have') {
o_fields.afe = {'l':'Afe','r':true,'t':'afelab'}

}
if (f.reboot_time.value) {
o_fields.ampm = {'l':'AMPM','r':true}
}

var tfv = new validator('form', o_fields);
return tfv.exec();
}.

That's it. Though it is certainly not modular it is easy enough to update on a form by form basis.
