    HTMLElement.dir

    The HTMLElement.dir property gets or sets the text writing directionality of the content of the current element.

    The text writing directionality of an element is which direction that text goes (for support of different language systems). Arabic languages and Hebrew are typical languages using the RTL directionality.

    An image can have its dir property set to "rtl" in which case the HTML attributes title and alt will be formatted and defined as "rtl".

    When a table has its dir set to "rtl", the column order is arranged from right to left.

    When an element has its dir set to "auto", the direction of the element is determined based on its first strong directionality character, or default to the directionality of its parent element.

    Syntax

    var currentWritingDirection = elementNodeReference.dir;
    elementNodeReference.dir = newWritingDirection;
    
    • currentWritingDirection is a string variable representing the text writing direction of the current element.
    • newWritingDirection is a string variable representing the text writing direction value.

    Possible values for dir are ltr, for left-to-right, rtl, for right-to-left, and auto for specifying that the direction of the element must be determined based on the contents of the element.

    Example

    var parg = document.getElementById("para1"); 
    parg.dir = "rtl"; 
    // change the text direction on a paragraph identified as "para1"
