jQuery UI Nested Sortable, sending additional data -

-

another question relating jquery ui nested sortable 1.2.1.

we call function this:

$(document).ready(function(){ $('ol.sortable').nestedsortable({ disablenesting: 'no-nest', forceplaceholdersize: true, handle: 'div', items: 'li', opacity: .6, placeholder: 'placeholder', tabsize: 25, tolerance: 'pointer', toleranceelement: '> div' });

i thinking how can send additional information through this, like:

$(document).ready(function(){ $('ol.sortable').nestedsortable({ disablenesting: 'no-nest', forceplaceholdersize: true, handle: 'div', items: 'li', left_val: '<?=$lft?>', root_id: '<?=$id?>',  opacity: .6, placeholder: 'placeholder', tabsize: 25, tolerance: 'pointer', toleranceelement: '> div' });

idea use 3 variables, left_val, root_id , holder in following fashion in toarray function.

var left = this.left_val; var root_id = this.root_id;

this not working, of course. values coming out nan, nan , undefined.

doing alert(left+' '+root_id); below var left = this.left_val; var root_id = this.root_id; giving me alert stating undefined undefined

the options of options coming parent plugin jquery ui.

just wondering if can throw light this, please.

edit:

i tried different trick. tried send left , root_id values through <ol class="sortable" title="<?=$lft?>|<?=$id?>"> , in js page, tried

if ($(this).parent().attr('class') == 'sortable') { var idarray = $(this).parent().attr('title').split("|"); }

but i'm getting $(this).parent().attr('class') undefined on alert.

have looked @ jquery.data() ? let store arbitrary data in key/value pairs element. jquery data() documentation

here more documentation link

javascript - Enclosure Memory Copies -

function myclass() { //lots , lots of vars , code here. this.bar = function() { //do numerous enclosed myclass vars } this.foo = function() { alert('hello'); //don't enclosed variables. } } each instance of myclass gets own copy of bar , foo, why prototyped methods use less memory. however, know more memory use of inner methods. it seems obvious me (1) below must true. agree? not distinct myclass instances have own distinct copies of bar, must have own distinct copies of myclass enclosure. (or else how bar method keep myclass variables straight on per instance basis?) now (2) question i'm after. since inner foo method doesn't use in myclass enclosure natural qustion is: javascript smart enough not keep myclass enclosure in memory use of foo? this depend entirely on implementation not language. naive implementations keep far more around others. answer true e.g. v8 (chrome's js engine) may not true spider...

example preg_replace('/\{[a-za-z.,\(\)0-9]+\}/', 'replaced', 'lorem ipsum dolor sit {tag1({tag2()})}, consectetur adipiscing elit.'); the result: lorem ipsum dolor sit {tag1(replaced)}, consectetur adipiscing elit. question as can see "tag2" has been replaced, want replace "tag1" know how can this? (in cases might this: {tag1({tag2({tag3()})})}) , on.) btw using preg_replace_callback, easier show preg_replace here site can test code: http://www.spaweditor.com/scripts/regex/index.php you need add curly braces character set. here's pattern used: /\{[a-za-z.,\(\)\{\}0-9]+\}/ and here result: "lorem ipsum dolor sit replaced, consectetur adipiscing elit."
