search - Need help with implementation of the jQuery LiveUpdate routine -

-

has worked liveupdate function (may bit of misnomer) found on this page? it's not live search/update function, quick filtering mechanism pre-existing list, based on pattern enter in text field.

for easier reference, i'm pasting entire function in here:

jquery.fn.liveupdate = function(list){   list = jquery(list);    if ( list.length ) {     var rows = list.children('li'),       cache = rows.map(function(){         return this.innerhtml.tolowercase();       });            .keyup(filter).keyup()       .parents('form').submit(function(){         return false;       });   }    return this;    function filter(){     var term = jquery.trim( jquery(this).val().tolowercase() ), scores = [];      if ( !term ) {       rows.show();     } else {       rows.hide();        cache.each(function(i){         var score = this.score(term);         if (score > 0) { scores.push([score, i]); }       });        jquery.each(scores.sort(function(a, b){return b[0] - a[0];}), function(){         jquery(rows[ this[1] ]).show();       });     }   } };

i have list, members id. , text field say, qs id.

i tried binding function in following manner:

$( '#qs' ).liveupdate( '#members' );

but when this, function called only once when page loaded (i put in console.logs in function) never after when text keyed text field. tried calling routine keyup() function of qs.

$( '#qs' ).keyup( function() {     $( ).liveupdate( '#members' ); });

this ends going infinite loops (almost) , halting "too recursion" errors.

so can please shed light on how supposed implement function?

also while @ it, can kindly explain line me:

var score = this.score(term);

what want know member method score() coming from? didn't find such method built js or jquery.

thanks help, m^e

score() comes quicksilver library. isn't extremely clear in post, john answers same question in comments.

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."
