JS get page element coordinates

JavaScript (obtain or set the width, height, and coordinates of HTML elements)
Settings:

Document. getelementbyid ('id'). style. width = Value
Document. getelementbyid ('id'). style. Height = Value
Document. getelementbyid ('id'). style. Top = Value
Document. getelementbyid ('id'). style. Left = Value

 

Obtain:

Value = Document. getelementbyid ('id'). offsetleft
Value = Document. getelementbyid ('id'). offsettop
Value = Document. getelementbyid ('id'). offsetwidth
Value = Document. getelementbyid ('id'). offsetheight

 

Find the coordinates of an element:

function findPosition( oElement ){  var x2 = 0;  var y2 = 0;  var width = oElement.offsetWidth;  var height = oElement.offsetHeight;  alert(width + "=" + height);  if( typeof( oElement.offsetParent ) != 'undefined' )  {    for( var posX = 0, posY = 0; oElement; oElement = oElement.offsetParent )    {      posX += oElement.offsetLeft;      posY += oElement.offsetTop;         }    x2 = posX + width;    y2 = posY + height;    return [ posX, posY ,x2, y2];       } else{      x2 = oElement.x + width;      y2 = oElement.y + height;      return [ oElement.x, oElement.y, x2, y2];  }}
