How to assign custom CSS class to arbitrary arbitrary rows of h:dataTable?
I开发者_StackOverflow中文版'm trying to assign a specific CSS class to specific rows of my <h:dataTable>
. Is there some way to access and cutomize the resulting table rows?
Bind the rowClasses
attribute to a bean property which returns the desired string of CSS classes.
<h:dataTable value="#{bean.list}" rowClasses="#{bean.rowClasses}">
with e.g.
public String getRowClasses() {
StringBuilder rowClasses = new StringBuilder();
for (Item item : list) {
if (rowClasses.length() > 0) rowClasses.append(",");
rowClasses.append(item.getRowClass());
}
return rowClasses.toString();
}
Update to clarify, this way you have full programmatic control over the rowClasses
string. Note that the above is just a kickoff example, it doesn't necessarily need to be obtained by Item#getRowClass()
or so. You can even do it in a simple for loop with a counter.
E.g.
public String getRowClasses() {
StringBuilder rowClasses = new StringBuilder();
for (int i = 0; i < list.size(); i++) {
if (rowClasses.length() > 0) rowClasses.append(",");
rowClasses.append(selected.contains(i) ? "selected" : "none");
}
return rowClasses.toString();
}
where selected
is a List<Integer>
. If it contains 1, 2 and 5, then the returned string will look like as follows for a list of 10 items:
none,selected,selected,none,none,selected,none,none,none,none
I like @BalusC suggestion. If you want a second alternative, you can do this easily with javascript/JQuery.
With JQuery you can do it like this
(Note, this is just an example. I haven't tested it, and there is probably a better way of doing it)
$(document).ready(function(){
var counter = 0;
$('#myTable').each(function() {
counter = counter + 1;
if(counter==3) {
$(this).addClass('redRow');
return;
}
});
}
