I'm trying to print java string return values into script java . this is my method in java class
public static String getchamps (){ //Bdconnection class
String str;
{
str = "date" ;
}
return str ;
}
the question is how can i have this code
<script type="text/javascript" >
"date"
</script>
You should in this context look at JSF as a HTML code generator. You can use JSF tags/components and EL expressions to let it produce the desired HTML output. As JavaScript is as being a client side language technically part of HTML (not of JSF!), you can just do the same for JavaScript.
Once you fix that bad static method to really comply the Javabeans specification as below:
public String getChamps() {
return "date";
}
Then you can just let JSF print it as if it's a JS variable as below:
<script>
var champs = "#{bean.champs}";
</script>
To verify the result, just open the JSF page in webbrowser and do rightclick, View Source. You should see something similar to:
<script>
var champs = "date";
</script>
Beware of JS-special characters in the string though! This would fail if the string contains e.g. a doublequote or even a newline. If that's the case, then you'd better escape it using an EL function as shown in this answer: Escape JavaScript in Expression Language.
Do this:
<h:inputText id="propertyId" value="#{Bdconnection.str}" />
and access in script
document.getElementById('propertyId').val();
