Java Reference
In-Depth Information
var msg = function msg(data) {
var resultArea = document.getElementById("AjaxGuess:result");
var errorArea = document.getElementById("AjaxGuess:errors1");
if (errorArea.innerHTML !== null && errorArea.innerHTML !== "")
{
resultArea.innerHTML="";
}
};
The
msg
function obtains a handle to both the
result
and
errors1
elements. If the
errors1
element has any content, the function erases the content of the
result
ele-
ment, so the stale output does not appear in the page.
The
UserNumberBean
Managed Bean
A small change is also made in the
UserNumberBean
code so that the output compon-
ent does not display any message for the default (null) value of the property
response
.
Here is the modified bean code:
public String getResponse() {
if ((userNumber != null) && (userNumber.compareTo(randomInt) ==
0)) {
return "Yay! You got it!";
}
if (userNumber == null) {
return null;
} else {
return "Sorry, " + userNumber + " is incorrect.";
}
}
