Why does my Javascript function not work? 9 Years ago Karma: 0
I have this function that needs to search for h1, h2, and h3 tags from within a given element id and concatenate together all the innerhtml of any heading tags it finds. If none exist then it will return the title of the page instead.

But i have been getting errors - the latest is

Error: findHeading.getElementsByTagName is not a function
Source File:
Line: 234

Here is my function, can anyone help?
function heading(){

headings = ["h1","h2","h3"];

for(var h=0;h<headings.length;h++){
if(findHeading.indexOf(headings[h] != -1)){
strHeading += findHeading.getElementsByTagName(headings[h]).item(0).innerHTML;
if(strHeading!= ''){
return strHeading.replace(/ /g, "_");
return mainTitle.replacec(/ /g, "_");
