default a value on dropdown in collection

Forms Version 10

Hi,

I am using the following code to default a value on a drop down within collection. The drop down has values from a lookup table. Also the 'defaultlocaton' field is outside the collection and it is a lookup value field. The script is working to default the value on targeted collection drop-down field. However, when a value is changed, I don't want the script to update the changed fields in the collection when a line gets appended. It should only update the default value on the new appended line.

Can someone please help with this script?

$('.cf-collection-append').click(function(){
grabVal() //deafult value for each GL drop downns in line
});

function grabVal() {
var loc = $('.defaultlocation input').val();
var a = '';
a = $('.cf-collection-block').find('.GLLoc option').filter(function () { return $(this).html() == loc;}).prop('selected', true);
}

You can do a for each which will cycle through the fields GLLoc from top down (no need to even reference that they are in a collection). When using the .each loop, $(this) accesses the current field. Check if they already have a value, if not then set a default value.

Call this each time they click append.

$('.GLLoc option').each(function(){

var currentValue = $(this).val();

if(!currentValue){
//This field does not have a value yet
$(this).val(YOURDEFAULTVALUE);

}

});

Hi Chad,

Tanks for your reply,

I tried this but couldn't get it going. do I need to have a trigger?

I have a default value field populated with a location. Within collection, I have a drop down that has a list from lookup. When the location field has a value, I want that location to to be defaulted on the drop don.

Thanks for your help,

I think I figure it. Using Select on the drop down worked. Thanks fro your help!

$('.GLLoc Select')

Yes that looks right, select is the type for drop down fields. I have never heard of an option type before but I just expected it was something I had not used. Still so much javascript to learn.

Ironic how you must specify the field type but you can't specify a variable type. Javascript makes me crazy.
