This is the javascript file that is being imported with the bookmarklet script, so as to allow the bookmarklet to capture the highlighted text and also to send the necessary data points to the server for SMS delivery.

text.js

function getSelText() {
  var txt = '';
	if (window.getSelection) {
		txt = window.getSelection();
	} else if (document.getSelection) {
		txt = document.getSelection();
	} else if (document.selection) {
		txt = document.selection.createRange().text;
	} else return;
	return txt;
}

function sendSMS( recipient ) {
	var body = getSelText();

	if ( body == '' ) {
		alert("You have not highlighted anything to send to your phone!");
	} else {
		// Create object.
		var http = new XMLHttpRequest();

		// POST
		var data = "recipient=" + recipient + "&body=" + body;
		var url = "http://www.andy-jiang.com/textme/send_sms/";
		http.open("POST", url, true);
		http.setRequestHeader("Content-type", "application/x-www-form-urlencoded");
		http.send(data);
		alert("A text was just sent to " + recipient);
	}
