FormAPI-Dropdown

System

Hi,

I want to clear the value and label of drop down using formapi.

I am getting value using the below statement

var index = IWDatacapture.getItem("/ProductCategories").getValue();
var option = IWDatacapture.getItem("/ProductCategories").getOptions();

option[index].value it will return value. But i want to do some things like this

option[index].value = '';
option[index].label='';

Any suggestion ??
Thanx in advance

After changing the options array, you need to re-set the options on the datacapture form:

IWDatacapture.getItem("/ProductCategories").setOptions(option);

Thanx for your reply

i used

IWDatacapture.getItem("/ProductCategories").setOptions(option);

Still it is not clearing the drop down?

Thanx in advance

Hmm, you made need an IWDatacapture.redraw after doing a setOptions. I can't remember for sure...

I'm assuming you called setOptions after making the other changes to the options array.

Use this instead, of course within a for loop. One thing make sure the val of num is a number.
IWDatacapture.getItem("/optionItemName").removeOption(parseInt(num) );

Thanx for your reply. It is working now with removeOptions()

Glad it's working for you...the problem with your other code was this line:

IWDatacapture.getItem("/ProductCategories").setOptions('');

It should read:

IWDatacapture.getItem("/ProductCategories").setOptions(option);

Of course, that won't take the option out of the select list, it will just create a blank option.

Hi,
alert(option[index].label);
doesnt work.........
It has to be alert(option[index].text.
The label can be accessed through text property.

Try this
