html - Applying variable to element jquery -


i'm wondering if can in jquery. i'm using version 1.10:

var myimage = $('#myimage');

what want assign image variable can use anywhere. want use during event handling:

e.g.

myimage.click(function () {     alert('image clicked'); });

if above code incorrect, know appropriate code.

yes can it. in fact, recommended assign variable selector not evaluated each time use it. performance reasons.

finding element id (such in case $('#myimage');) fast imagine if have selector like

$('ul > li.myclass:has(p) a:eq(2)')

using variable speed things in such scenarios.

i use $ sign in variable name like. var $varname = $('.selector') helps me better understand code , distinguish between regular variables , variables contain dom elements.

scala - 'wrong top statement declaration' when using slick in IntelliJ -

Image
i'm porting project scala 2.9 2.10, therefore have use slick instead of scalaquery. i'm using slick 2.1.0 since supports ms access. according this tutorial , upgrade guide changed robs object class , added val robs : why error message wrong top statement declaration , how rid of it? edit: i'm new scala... according this question seems can't put val outside of methods or classes, right? code above directly in packge. right approach slick then? should move code in class or trait? according this changed val robs = tablequery[robs] to object robs extends tablequery(new robs(_)) {} . no warnings or errors anymore. :)
