javascript - Dynamically show data in the popup which is determined in onpopupshowing event handler -

-

i developing firefox extension. on 1 <menupopup>, onpopupshowing calls javascript function. javascript function extracts list of names. these names have displayed in same popup.

how can this? need pass data (just use beans in java) browser javascript function. data can change every time popup called.

you need modify dom rapresenting menupopup. example:

<menulist>   <menupopup id="mymenupopup">     <menuitem id="firstitem" label="mozilla" value="http://mozilla.org"/>     <menuitem id="seconditem" label="slashdot" value="http://slashdot.org"/>     <menuitem id="thirditem" label="sourceforge" value="http://sf.net"/>   </menupopup> </menulist>

now if want add item:

var mymenupopup = document.getelementbyid("mymenupopup"); var newitem = document.createelement("menuitem"); newitem.setattribute("id", "anotheritem"); mymenupopup.appendchild(newitem);

if want remove item:

var itemtoremove = mymenupopup.getelementbyid("anotheritem"); mymenupopup.appendchild(itemtoremove);

here can find more:

edit:

i assume thet function returns array of names:

var namelists = yourfunction();  (var i=0; i<namelist.length; i++){   var newitem = document.createelement("menuitem");   newitem.setattribute("label", namelist[i]);   newitem.setattribute("id", "item" + i);   mymenupopup.appendchild(newitem); }

i think better if call function make items before user click on menupopup, not on event invocation, because if have many items may takes little construct items list.

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."
