I have to use JSF to pop up a window from the parent
window. In the popup window, I have to pass the value
that is entered in a <h:inputText> back to a text
field in the parent window.
In order to make sure that I know the way to
communicate between the parent window and the popup
window, I have tried coding it in HTML. And I have
done it successfully.
Then, I try to convert the HTML code to JSF. I have
searched the internet and I have tried different
specifications myself. I am stuck. This is the line
that I have been struggling with:
[CODE]
window.opener.document.forms[0].form["dataManagement:textField"].value
=
document.forms[0].form["externalFile:inputField"].value;
[/CODE]
If textField is in HTML parent window <input
name=textField .... /> and the inputField is in HTML
popup window <input name=inputField .... />, the
JavaScript can recognize (No problem! the datum is
passed.):
[CODE]
window.opener.document.forms[0].textField.value =
document.forms[0].inputField.value;
[/CODE]
Now, the dataManagement is the "id" attribute in my
JSF parent <h:form> tag. The externalFile is the "id"
attribute in my JSF popup <h:form> tag.
The textField is in the JSF parent window as both the
"id" attribute and a "property" name (i.e.
value="#{dataManagementBean.textField}" )in the
<h:inputText> tag.
The inputField is in the JSF popup window as both the
"id" attribute and a "property" name (i.e.
value="#{accessExternalFileBean.inputField}" ) in the
<h:inputText> tag.
No matter how I experiment with different
specifications, I cannot get the textField and
inputField in the JavaScript. I got that "it is null
or not an object" JavaScript error. Please advise if
you have done it successfully.
