Let's say I have the following table in my XHTML page:
<tr:table id="listRowsTable" var="bb"
value="#{backingBean.results}"
emptyText="Empty" width="100%"
rowSelection="multiple"
binding="#{backingBean.table}"
rows="#{backingBean.numRows}"
rowBandingInterval="1">
I'd like to implement a client-side check, such that when the user clicks on the submit button, if the number of rows selected exceeds a certain number then a prompt appears asking him/her to confirm his/her submission.
Can this be done using Javascript? If so, how should I proceed?
You could use jQuery to get the elements and then check if .length is what you expect but although i am not sure exactly how i would do something like this
if($('tr:selected').length > SOMETHING){
//do anything
}
