dacur / autogrow.js

Created June 13, 2014 16:14

Autogrow.js allows a textbox to grow in size vertically instead of populating a scroll bar and hiding text while you continue to type. Example below is used in conjunction with Bootstrap and AJAX. The last few lines of code reset the box size each time "submit" button is clicked; otherwise, the text box remains the last (larger) size after click…

	(function($){
	//pass in just the context as a $(obj) or a settings JS object
	$.fn.autogrow = function(opts) {
	var that = $(this).css({overflow: 'hidden', resize: 'none'}) //prevent scrollies
	, selector = that.selector
	, defaults = {
	context: $(document) //what to wire events to
	, animate: true //if you want the size change to animate
	, speed: 200 //speed of animation
	, fixMinHeight: true //if you don't want the box to shrink below its initial size
