measuredUnit

Widget to wrap DVQuantity element.

Usage:

$('#measured-input').measuredUnit([options]);

Options:

• DefaultValue: Current value of DV_Quantity
  • Value: measured value
  • Unit: value's unit.
• AssumedValue: the value set to the control if user has not touched it and nothing was passed as Value and Unit
  • Value: assumed value itself
  • Unit: assumed value unit
• Required: specifies whether the value can be empty (Required:false) or not (Required:true)
• Units: hashtable of possible unit measures
  • key is a string and contains measure
  • value is an object, containing:
    • precision: Precision, in terms of number of decimal places. Value 0 implies integer value, -1 implies no rounding and the value is stored as is
    • minValue: minimal bound of value
    • maxValue: maximal bound of value
• PropertyName: Name of the measured property, e.g. "temperature". Used in value conversion.
• getValueConverter: function fabric that returns function-converter for chosen property, fromUnit, toUnit

Example: Human body temperature field. Assumed value - "36.6 C". Bounds - alive human being bode temperature - from 35 to 42 degrees. Can be converted to Fahrenheight

$('#measured-input1').measuredUnit({
	AssumedValue: { Value: 36.6, Unit: 'C' },
	DefaultValue: { Value: 36.6, Unit: 'C' },
	Required : true,
	Units: {
		'C' : {
			precision: 1,
			minValue: 35,
			maxValue: 42
		},
		'F' : {
			precision: 1,
			minValue: 95,
			maxValue: 107.6
		}
	},
	PropertyName : 'temperature',
	getValueConverter: function (property, fromUnit, toUnit){
		switch(property){
			case 'temperature':
				if (fromUnit === 'C'  && toUnit === 'F'){
					return function (value) {
						return (value * 9 / 5 + 32);
					};
				}
				if (fromUnit === 'F'  && toUnit === 'C'){
					return function (value) {
						return ((value - 32) * 5 / 9);
					}
				}
		}
	}
});
