npm install range-class-js

Kind: global class

• Range
  • new Range(range)
  • .min : Number
  • .max : Number
  • .step : Number
  • .stepNormalizer : Number
  • .isValid(Number) ⇒ Boolean
  • .load(range) ⇒ Boolean

new Range(range)

creates a new range instance

Param	Type	Description
range	Object	Object containing min max and step

Example

const Range=require('range-class-js');
 
const range1=new Range;
range1.min=0;
range1.max=100;
range1.step=10;
 
const range2=new Range;
range2.load(
        {
            min:0,
            max:50,
            step:5
        }
);
 
const range3=new Range(
        {
            min:0,
            max:10,
            step:1
        }
);

Range.min : Number

range min, set via load method or directly

Kind: static property of Range

Range.max : Number

range max, set via load method or directly

Kind: static property of Range

Range.step : Number

range step, set via load method or directly

Kind: static property of Range
Default: 1e-2 (0.01)

Range.stepNormalizer : Number

used to normalize values and steps during valid calculations

Kind: static property of Range
Default: 1e10

Range.isValid(Number) ⇒ Boolean

checks if number is valid in range with given step

Kind: static method of Range
Returns: Boolean - Number is valid value in range with given step
Access: protected

Param	Type	Description
Number	Number	to check against range and step

Example

const Range=require('range-class-js');
 
const range=new Range;
range.load(
    {
        min:0,
        max:5,
        step:1
    }
);
 
let valid=range.isValid(1.5);
//valid===false
 
valid=range.isValid(2);
//valid=== true

Range.load(range) ⇒ Boolean

converts an Object into a Range and checks validity

Kind: static method of Range
Returns: Boolean - success
Access: protected

Param	Type	Description
range	Object	the range values

Example

const Range=require('range-class-js');
 
const range=new Range;
range.load(
    {
        min:0,
        max:5,
        step:0.05
    }
);
