function trimreport () { 'use strict'; var reporttxt = document.getelementbyid('raportinput'); var str = reporttxt.value; var re = /\<tr\>/gmi; var result = []; var val; var match; var div = document.getelementbyid('output'); while (match = re.exec(str)) { val = match.index; result.push(val.lastindex); div.innerhtml = div.innerhtml + val + '<br>'; //console.log(match.index); }; div.innerhtml = div.innerhtml + result + '<br>'; //console.log(result); }; //initial function: function init() { 'use strict'; if(document && document.getelementbyid) { var bttn = document.getelementbyid('run'); bttn.onclick = trimreport; } //if end //alert('inside init'); //console.log('inside init'); }//init end window.onload = init; html code:

you have multiple related errors in while loop. see documentation on regexp.exec() function see how use correctly. immediate errors are:
valinteger (i.e., "0-based index of match in string"), not object.- the
lastindexproperty belongsreobject.
see link provided above example of how loop correctly.
