Question

I am playing around with dom manipulation and js and I am running into a problem.

Let's say I have <p id = "description"> Lorem ipsum dolor sit amet, consectetur adipiscing elit. Cras facilisis, felis et sagittis eleifend, justo ante maximus augue, id porta massa elit a ligula. </p> <p id = "description"> Lorem ipsum dolor sit amet, consectetur adipiscing elit. Cras facilisis, felis et sagittis eleifend, justo ante maximus augue, id porta massa elit a ligula. </p>

and I want to write a function that counts a number of repeated letters in a paragraph. I figured out how to do that with a string but not with paragraphs.

    function recurringLetters() {
      var myParagraph = document.getElementById("description").innerHTML;
  }
}

Any thoughts?

This is how far I have gotten.

Hope This Answers your Question . Just Copy & Paste into an HTML file for testing.

 function WORD_COUNT( _THIS_ , _WORD_ ){ var TEMP = _THIS_.innerHTML; var COUNT= 0; // IF TEMP search result finds nothing, return is -1, so -1 is our stopping point while(TEMP.search(_WORD_)>-1){ TEMP = TEMP.replace(_WORD_,''); COUNT++; document.getElementById('output').innerHTML=COUNT; }}

 <p onmouseover=WORD_COUNT(this,'us');>PUT YOUR MOUSE OVER ME.<BR> Lorem ipsum dolor sit amet, consectetur adipiscing elit. Cras facilisis, felis et sagittis eleifend, justo ante maximus augue, id porta massa elit a ligula. </p> <p ID=output>Output area<p>
