Note:

  1. I need ascent descent and CapHeight of font and not just line-height.
  2. Need metrics using client-side Scripting(JavaScipt).

You can use opentype.js to parse a font to get values in the font's OS/2 table. For ascent, descent and cap height, use the sTypoAscender, sTypoDescender and sCapHeight fields.
