Hi,
Here, we want to display a value input in a text box using a Javascript alert in a xhtml form as designed in the jbpm-jpdl designer. However, the code is giving an error. The error is :
"document.forms.form1.textbox' is null or not an object"
The code is as follows.
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd" >
|
|
| <!-- the DOCTYPE means we are required to use html for a root element -->
|
| <html xmlns="http://www.w3.org/1999/xhtml"
|
| xmlns:ui="http://java.sun.com/jsf/facelets"
|
| xmlns:c="http://java.sun.com/jstl/core"
|
| xmlns:h="http://java.sun.com/jsf/html"
|
| xmlns:f="http://java.sun.com/jsf/core"
|
| xmlns:tf="http://jbpm.org/jsf/tf"
|
| xmlns:jbpm="http://jbpm.org/jsf">
|
|
| <script language="java-script">
|
| function foo()
|
| {
|
| alert("Hi");
|
| }
|
| function showTextBox()
|
| {
|
| alert(document.forms['form1'].textbox.value);
|
| }
|
| </script>
|
|
| <FORM name="form1">
|
| textbox: <INPUT name="textbox"/><BR/>
|
|
|
| <!-- the below onClick is not working -->
|
| <INPUT type="button" value="val" onClick = "showTextBox()" />
|
| <A href="#" onclick = "foo()">href</A>
|
|
|
|
| <h:outputText value="#{taskName}"/>
|
|
|
| <!-- TASKFORM ROWS -->
|
|
| <h:outputText value="Variable 1"/>
|
|
| <h:inputText value="#{var['variable1']}" />
|
|
|
|
|
| <h:outputText value="Actions"/>
|
| <!-- TASKFORM BUTTONS -->
|
| <tf:saveButton value="Save"/>
|
| <tf:cancelButton value="Cancel"/>
|
| <tf:transitionButton to="Done" value="Done"/>
|
| </FORM>
|
|
| </html>
How do we solve this problem.
Thanks a lot in advance.
