JavaScript to limit the size of image display

This article describes the method of limiting the display size of images in JavaScript. Share it for your reference. The specific implementation method is as follows:

/**
  * Limit the size of the image display.
  *
  * @param thisobj Image component
  * @param limitW limits width size
  * @param limitH Limit height size
  */
function imageResize(thisobj, limitW, limitH) {
  var newW;
  var newH;
  if ( &gt; limitW) {
    newW = limitW;
    newH = parseInt( * newW / );
 // Scale by width    if (newH &gt; limitH) {
      newH = limitH;
      newW = parseInt( * newH / );
    }
     = newW;
     = newH;
  } else if ( &gt; limitH) {
    newH = limitH;
    newW = parseInt( * newH / );
     = newW;
     = newH;
  }
}

I hope this article will be helpful to everyone's JavaScript programming.
