Hi, everyone
I started writing jquery from last week with the help from a very good
book Learning Jquery.
I met a problem when reading the book, which has the script:
<code>
$table.find('tbody tr').show()
.lt(2)
.hide()
.end()
.gt(5)
.end();
</code>
Where 2 and 5 are different from the book, but I think it has no
effect to the problem.
I haven't met a lt or gt method before, I can only write
<code>
$table.find('tbody tr:lt(2)').hide();
$table.find('tbody tr:gt(5)').hide();
</code>
I tried the author's code, which didn't work on my browser. the
browser said
"TypeError: $("table").find("tbody tr").show().lt is not a function"
I also tried this way:
<code>
var $trow=$table.find('tbody tr')
$trow.lt(2).hide()
<code>
the problem still exists there.
My question is:
Is lt or gt a method used as a selector ?
If I want to implement the chain actions like the first code, how
could I do that?
Any help is appreciated. thanks very much. Happy new year.
