EXAMPLE 21
Using the ChooseOne parameter type, we can enhance the previous example to limit the
business unit to be one of a small number of predefined values:
var workflow = {
name: 'Create share',
description: 'Creates a new share in a business unit',
parameters: {
name: {
label: 'Name of new share',
type: 'String'
},
unit: {
label: 'Business unit',
type: 'ChooseOne',
options: [ 'development', 'finance', 'qa', 'sales' ],
optionlabels: [ 'Development', 'Finance',
}
},
execute: function (params) {
run('shares select ' + params.unit);
run('filesystem ' + params.name);
run('commit');
return ('Created new share "' + params.name + '"');
}
};
When this workflow is executed, the unit parameter will not be entered by hand -- it will be
selected from the specified list of possible options.
Optional Workflow Parameters
Some parameters may be considered optional in that the UI should not mandate that these
parameters are set to any value to allow execution of the workflow. Such a parameter is denoted
via the optional field of the parameters member:
