HTMLElement.tabIndex property represents the tab order of the current element.
element.tabIndex = index index = element.tabIndex
- index : number
Tab order is as follows:
- elements with a positive tabIndex. Elements that have identical tabIndexes should be navigated in the order they appear. Navigation proceeds from the lowest tabIndex to the highest tabIndex.
- Elements that do not support the tabIndex attribute or support it and assign tabIndex to "0", in the order they appear.
Elements that are disabled do not participate in the tabbing order.
Values don't need to be sequential nor must they begin with any particular value.
var b1 = document.getElementById("button1"); b1.tabIndex = 1;
