Re: CheckBox handling with Ajax.
Hi All,
I am unable to write Ajax method to make a button visible and unchecked it
should'nt be made visible.
heres my bit of code,
1.) this is like a PoP screen which comes up and i need to check the
checkbox and after which the button will be made visible and also if
unchecked it should made invisible
add(new CheckBox(A, new Model() {
@Override
public Object getObject() {
return B;
}
@Override
public void setObject(Object object) {
B= (Boolean) object;
}
}));
@Override
public boolean isVisible() {
// TODO Auto-generated method stub
return super.isVisible() bean == null !B;
}
@Override
protected void onSubmit() {
if (log.isDebugEnabled())
log.debug(String.format(Accepted terms of use?
%b, B));
if (!B) {
error(getLocalizer().getString(errors.XYZ.termsOfUseNotaccepted,
Filename.this, Please accept terms of use to proceed));
return;
}
}
2.) Now this is my bit o code after i hit the button successfully and i will
abe to view the page to upload some data,
@Override
public boolean isVisible() {
// TODO Auto-generated method stub
return super.isVisible() B;
}
@Override
protected void onSubmit() {
Filename.this.resetModel();
FileUpload upload = fileUploadField.getFileUpload();
if (log.isDebugEnabled())
log.debug(String.format(Submitted file upload:
%s, upload));
if (upload == null) {
error(getLocalizer().getString(mapviewer.excel.no_data, Filename.this,
Please choose a file.));
return;
}
What do suggest me to do going forward?
Thanks,
Varun

Well you need to put the component (say component) which you want to make
invisible into target and then set
component.setOutputMarkupPlaceholderTag(true).
Let me know if that works.

Re: CheckBox handling with Ajax.
Yes the code that you are putting in is for an onUpdate() method which means
that whenever the state of the checkbox gets changed only then the code will
be executed. So if you check it, something should happen and when you
uncheck it then again something should happen.
Also did u try to use the setOutputMarkupPlaceholdertag to true. I had a
similar issue like you and I was able to get it to work with that.
