DropdownBox Dynamic - display value versus stored value

[RobGordon]

Scenario: Mobile Application using UX Drop down box called Customers, that shows the CustomerName field from SQL table where CustomerID is primary key.

CustomerID CustomerName
1 Rob G
2 Andy P
3 Tommy T

The user selects from this dropdown and the CustomerID is then used as an argument in a List component.

I also want to reference the selection chosen by the user, but the following Javascript returns the CustomerID

eg. varCustomerSelected = {dialog.Object}.getValue('Customers')
returns 1 and not Rob G

Apologies if this is bl**dy obvious, I have attempted to search the forums and videos, but what do I have to do to reference the displayed value not the stored value???

Cheers in advance
Rob

Re: DropdownBox Dynamic - display value versus stored value

I don't think you can easily reference the displayed value, it is for display only. I think you have the following options:

1) Concatenate the two fields so that you have 1 field with the value: "1 Rob G". You might even make it "1: Rob G" so you can use the ":" to help separate the two. Then pull the value apart to get the separate components. (You can even display Rob G and return 1 Rob G)

2) Leave it as is, but after you get the ID value (1) Use Xbasic to do another call back to get the name.

3) Use Firebug to analyze the component. The display value is hidden in the javascript somewhere, it's just a matter of finding the correct JavaScript reference to access it. (But I think option 1 is your easiest and least chatty solution.)

Another thing to consider is using Textbox fields instead of Dropdown and adding a Lookup definition to the Textbox. This is what I opted for in my app because I wanted all "dropdowns" to behave exactly the same. When you use a Textbox with Lookup definition you can have the Lookup populate multiple fields and I just include extra hidden fields or display fields on my forms that get populated with the fields I want from the lookup table. Video #8 shows these types of lookups.

Wondering if you ever got an answer to this? I would like to reference the displayed value of a radio button which I assume would be a similar if not identical process.

This current video gets you close as it explains how to get the display value of a dropdown control.

Radio buttons are similar, but not quite the same. With a little tweeking to the original code, this code gets you what you want from a Radio Button...

var x = {dialog.Object}.getValue('radioBtn');
if(x == '') return;
var ele = {dialog.Object}.getPointer('radioBtn');
var e2 = ele.children;

var arr = [];
for(var i = 0; i < e2.length; i++){
	if(e2[i].children.length>0){
		delete obj;
		var obj = {};
		obj.text = e2[i].textContent;
		obj.value = e2[i].children[0].value;
		arr.push(obj);
	}
}

var indx = {dialog.object}._findArrayProp(arr,'value',x);
var display = arr[indx].text;
alert('value: ' + x + ' -- display: ' + display);
