How to append both single and double quotes in same function

How to append both single and double quotes in same function

Hi,

I am trying to append the single quote and double quote in the same function, but I am unsuccessful. Please help me in doing this.

HTML:

<input type="button" value="click" id="clickc" onclick="helloMan()"/>
<div id="mainDiv"></div>

JAVASCRIPT:

function helloMan(){
      var dialogue = " I'am Suren and I asked him a question, for which he replied, "I don't know !"";
      getName(dialogue);
}  
  
function getName(name){
      $("#mainDiv").append("<div>"+name+"</div>");
}


Thanks in advance, 
Surendar
