  if(mem1){

    strArr = mem1.value.split('\n');

	for(var i=0; i<strArr.length; i++){

	  var str = strArr[i];

	  while(str.indexOf(' ')==0){

	    str = str.substring(1);

	  }

	  strArr[i] = str;

	}

    mem1.value = strArr.join('\n');

  }

}

use regular expressions to remove the leading white space:

var mem1 = document.getElementById('mem1');

mem1.value = mem1.value.replace(/^\s+/, '');

to get the number of lines, the quickest (although not most elegant) solution is

count = mem1.value.split(/\n/).length;
