options

new EllipsisText(HTMLElement, {
  str: String,
  row: Number,
  scrollTop: Number,
  callback: function(res) {}
})

method

ellipsisText.reCompute(str,callback)

Recalculate and return the new result,this will save a lot of time than initialization

ellipsisText.dotdotdot(ellipsis = "...", str)

Tips

EllipsisText used canvas to determine the number of lines to be intercepted

If you pass in HTML, it deletes the nodes one by one to find the last text node that exceeds the height

function dotdotdot just replace last three letter, but you can use dotdotdot.js to do the following or rewrite this function
