Javascript – Control OptionSet values

Here is an example of a function to limit the values of an optionset, in this example I have a field called priority and want to be able to control when some options are selectable.

First off all, I define the options and text values that are possible in the optionset, theses are global variables.

var low = {value : 100000000, text : "Low"};
var medium = {value : 100000001, text : "Medium"};
var high = {value : 100000002, text : "High"};
var reallyHigh = {value : 100000003, text : "REALLY REALLY HIGH"};

Then this function, removes all of the current values and adds back just the ones I want to be selectable. This function is then calls from anywhere needed.

As either popOptSet(true); – to show all values.

Or popOptSet(false); – to show a restricted set.

function popOptSet(all) {
  var pickList = Xrm.Page.getControl("new_priority");
  var options = pickList.getOptions();

  // *** Clear current items
  for (var i = 0; i < options.length; i++) {
    pickList.removeOption(options[i].value);
  }

  // *** Now add back just what is needed
  if (all == true) {
    pickList.addOption(reallyHigh);
  }

  pickList.addOption(low);
  pickList.addOption(medium);
  pickList.addOption(high);
}

Hopefully you can amend this concept for you own purposes.

Happy coding! J
