How to add items to a dropdown list (selection list)
I need to create the following: 1. A button named AddList with label Add to List. 2. A Character field called eg new_item. 3. A dropdown list initially empty (ie no dropdown items) The user enters text into the new_item field and clicks on AddList button to add the text item in new_item to the dropdown. I have scoured the docs and can't quite work it out. How would I do this? Angus ___ UNSUBSCRIBE or access ARSlist Archives at www.arslist.org "Where the Answers Are, and have been for 20 years"
Re: How to add items to a dropdown list (selection list)
Hi, The drop-down-list must be created as a char-field with a search-menu attached. You can set the display-attributes so that it looks like a drop-down-list. When you "Add" stuff, you must create records in a form, that will later be displayed in your search-menu. Use the Push-Fields action to create records.

Re: How to add items to a dropdown list (selection list)
Hi,
We were just looking into this with Laurent this morning for another
requirement. The cleanest solution is clearly Misi's.
There just two drawbacks :
- you have to manage a table for your temporary records (=> delay,
clustering, i/o ...) or use a "temporary table" if your DBMS allows it
- it implies a delay on the client-side
Now there is a client-side only solution with JavaScript (yes, AGAIN :p).
You need a dummy character menu, named "EmptyMenu" in my example. Attach it
to your field.
The following code must be run from a Run Process action in an active link,
and re-creates the dummy menu with the values you pass to the object
constructor :
javascript new
ARMenu("EmptyMenu",{novals:false,mval:[{l:"val1",v:null},{l:"val2",v:null}]});
I can't test it right now, but this code _should_ work to add an item :
javascript window.ARMenus["EmptyMenu"].mval.push({l:"label",v:"value"});
new ARMenu("EmptyMenu",window.ARMenus["EmptyMenu"]);

Lol, I had not seen this thread yesterday when I pointed out your
JavaScript docs. Good timing. With this and Laurent's additional findings
it looks like there is some material for a part 3.

Re: How to add items to a dropdown list (selection list)
Brilliant, I will give it a try. It wasn't the most urgent thing so got dragged onto other things. But will need to return to this shortly and if I get it working will post how I did it. ___ UNSUBSCRIBE or access ARSlist Archives at www.arslist.org "Where the Answers Are, and have been for 20 years"

Hi :)First message on ARSLIST ^_^ (wt)... Time to grow up? I remember when I spoke about that with LJ at WWRUG12 that community was for kids and ARSLIST for grownups :)But well... Kids like to hang with grown ups from time to time so bear with me ;)So, as Sylvain told we worked a bit on this, "overwriting" a character menu with data coming from an external source (JSON for example), it seems that in 7.6.04 it's a bit different and it has an extra parameter.The ARMenu object in ClientCore.js from 7.6.04 has this construction:function ARMenu(windowID, menu_name, menu_data)So you just need to add the "windowID" to the code Sylvain gave, it seems it's 0 by default, here what I did in an active link (run process):_javascript_ new ARMenu(0,"_lma:test_charmenu",{novals:false,mval:[{l:"menu 1a",v:"val menu 1a"},{l:"menu2a",v:"val menu 2a"}]});And it worked.I tried the window.ARMenus part but it failed with a "window.ARMenus is undefined".It seems ARMenus is a local variable used in the function "Form_Init".Anyway, you can construct the "new ARMenu(0,"_lma:test_charmenu",{novals:false,mval:[{l:"menu 1a",v:"val menu 1a"},{l:"menu2a",v:"val menu 2a"}]});" part and run it to overwrite the menu.Le 07 jan 2013 à 16:25, Sylvain YVON a écrit :**Hi,We were just looking into this with Laurent this morning for another requirement.

Ok I can confirm that works, I used on a display form with three cascading lists, those values are from a php script linked to a mysql database:When you choose a tier 1, tier 2 and tier 3 are reloaded "live" accordingly:Here is the js code I used to build the menu, the goal is to have this (I used JQuery for this):new ARMenu(0,"_lma:test_charmenu",{novals:false,mval:[{l:"menu 1a",v:"val menu 1a"},{l:"menu2a",v:"val menu 2a"}]}); //Calling the php file that returns the json array.//json array is like this in case you want to test (don't bother the parameters operation, tier1, tier2)://{"saran_15::bananes_5::ananas_0":"saran_15::bananes_5::ananas_0","saran_15::bananes_5::ananas_1":"saran_15::bananes_5::ananas_1","saran_15::bananes_5::ananas_2":"saran_15::bananes_5::ananas_2","saran_15::bananes_5::ananas_3":"saran_15::bananes_5::ananas_3","saran_15::bananes_5::ananas_4":"saran_15::bananes_5::ananas_4"} $.getJSON("http://192.168.0.14/testjson/testjson/get_tier.php", { operation: myOp, tier1: myvalueT1, tier2: myvalueT2 }, function(json){ var i=0; var my_mval=new Array(); //traversing the json answer $.each(json,function(key,value){//Creating the menumy_mval.push({l:key,v:value});i++; }); //Creating the ARS menu now :) new ARMenu(0,"_lma:test_charmenu",{novals:false,mval:my_mval});});With this you'll overwrite the data that were in the menu "_lma:test_charmenu".Le 07 jan 2013 à 21:52, "laurent matheo" a écrit :Hi :)First message on ARSLIST ^_^ (wt)...
