以下是获取潜水内容行号的演示：

http://jsfiddle.net/brunoscopelliti/EPms9/

$(document).ready(function() {
  	var divheight = $("#startegy-sections-targeting-exclude").height(); 
	var lineheight = $("#startegy-sections-targeting-exclude").css('line-height').replace("px","");
	alert(Math.round(divheight/parseInt(lineheight)));
});

#startegy-sections-targeting-exclude {
	line-height:20px;
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="startegy-sections-targeting-exclude">
  Something strange... <br/>maybe it's fault of the measure unit<br/>PX!
</div>
