In the below JSP when I enter values for the text box and radio button and click Submit, the results are displayed on the page only momentarily and then it disappears. I am not sure what is the issue with code and I have spent hours on the issue. Please help.
<html>
<head>
<title>Java Solution AJAX</title>
<script type="text/javascript">
var request;
function getTemp() {
var value = document.getElementById("value").value;
for ( var i = 0; i < document.temp.Degree.length; i++) {
if (document.temp.Degree[i].checked) {
var Degree = document.temp.Degree[i].value;
break;
}
}
//var Degree = document.getElementById("Degree").value;
var url = "http://localhost:8080/mc1/ConverterServlet?value=" + value
+ "&Degree=" + Degree;
if (window.ActiveXObject) {
request = new ActiveXObject("Microsoft.XMLHTTP");
} else if (window.XMLHttpRequest) {
request = new XMLHttpRequest();
}
request.onreadystatechange = showResult;
request.open("GET", url, true);
request.send();
}
function showResult() {
if (request.readyState == 4) {
if (request.status == 200) {
var response = request.responseXML;
var temparatures = response.getElementsByTagName("Temperature");
var temparature = temparatures[0];
document.getElementById("inputTempS").innerHTML += temparature
.getElementsByTagName("inputTemp")[0].text;
document.getElementById("outputTempS").innerHTML += temparature
.getElementsByTagName("outputTemp")[0].text;
document.getElementById("conversionS").innerHTML += temparature
.getElementsByTagName("conversion")[0].text;
}
}
}
</script>
