HTMLInputElement: step property

The step property of the HTMLInputElement interface indicates the step by which numeric or date-time <input> elements can change. It reflects the element's step attribute. Valid values include the string "any" or a string containing a positive floating point number. If the attribute is not explicitly set, the step property is an empty string.

Value

A string representing the element's step value or an empty string if no step is explicitly set.

Example

const inputElement = document.querySelector('[type="number"]');
console.log(inputElement.step); // the current value of the step attribute
inputElement.step = 0.1; // sets the step value to "0.1"
inputElement.step = "any"; // sets the step to "any"
