아래는 예제입니다. 긁어서 실행해 보세요.

<script type="text/javascript">

  var arrErrors = new Array();

  window.onerror = function ( strErr, strURL, strLineNumber ) {
    strMess =  "URL: " + strURL + "nline number: " + strLineNumber + "nError Message: " + strErr;
    arrErrors.push(strMess);
    alert(arrErrors.join("n__________nn"));
  }

  function Test(){
    alert(aVariable.toString());
  }

</script>

<input type="button" name="b1" value="Create Error 1" onclick="Test()">
<input type="button" name="b2" value="Create Error 2" onclick="Test1()">
