In Jquery Can I append and add attr like: for this:
<li class="test" ln="7" >
How do I get the value of r into this:
$('#box input[name= _def]').val( JUNK) + "VALUE OF ln";
Can I get the value of custom attribute 'ln' appended after the val ?
Use a data- attribute to hold your data:
<li class="test" data-ln="7" >
You can add the attribute with jQuery using .data():
$li.data('ln', 7);
And you can use .data() to extract it (and automatically convert common data types):
var ln = $li.data('ln');
setAttribute() for browsers that don't support HTML5 data attributes.
Better to use HTML-5 data attributes for validated HTML..
This is supported by all the browsers.
<li class="test" data-ln="7" >
var val = $('li.test').data('ln');
For such cases you can use .data() method to extract the value.
If you still want to follow the same syntax that you are using which is not recommended, you can use the getAttribute method
var val = document.getElementsByClassName('test').getAttribute('ln');
attr?
