document.getelementbyid('mybutton').onclick = function() {    //set var equal exam name    var mystring = document.getelementbyid('mystring').value;    //if lc check , exam name isn't empty    if (document.getelementbyid('lc').checked && mystring.trim().length > 0) {      var lcsubjecttext = "test";      document.getelementbyid('myspan').innerhtml = lcsubjecttext;    }    //if jc check , exam name isn't empty    else if (document.getelementbyid('jc').checked && mystring.trim().length > 0) {      var jcsubjecttext = "test";      document.getelementbyid('myspan').innerhtml = jcsubjecttext;    }    //if exam name empty    else if (mystring.trim().length == 0) {      alert("please enter exam name");    } else {      alert("please choose either option 1 or option 2");    }  }
.inner {    padding: 10px 15px;    border-top: 1px solid #ddd;    border-top: 1px solid rgba(0, 0, 0, 0.15);    background-color: #fff;    box-shadow: none;  }  #mystring {    display: block;    margin: 0 auto;    width: 125px;  }  .mydiv {    padding: 0px 0px 10px 0px;  }  .mybutton {    padding: 100px 0px 0px 0px;  }
