i have use case allow people type values text box of select2 plugin not appear in select list. in 1 case providing validation , not submit unless user has valid item selected until do not want clear values. select box might contain 1.00, 1.50, 1.75, na, abs , user has typed 1.80. invalid value don't want lose changes, flag box invalid , allow them fix changes. not want add 1.80 select box invalid value, don't want clear either. how possible achieve this? if you're validating in js, select2 has example dynamic loading/generating data overrides query() repeats user's input. see: http://ivaynberg.github.io/select2/ 'loading data' i solved similar problem (server-side) jquery ui 'autocomplete'. here, took approach of returning objects wrapping both label possible explanatory message, text value without decoration, , combined id value & status flag . overrode select store text & id hidden fields. in case, distinguishing b...

i'm sure i'm missing obvious, but: how respond keypress event anywhere on page? for example, had video player , wanted pause if user pressed spacebar @ point. or, i'm writing game , want arrow keys direct character, without regard specific views or subviews. defining app.applicationview = ember.view.create({ keypress: whatever }) doesn't seem work. have thought keypress events bubble that. i guess want is: $(document).keypress(function(e) { alert('you pressed key!'); }); except through ember. if looking global keypress code example above best solution. ember application attached body (or root element you've defined) , require sort of focus on view. example do: app.applicationview = em.view.extend({ keyup: function(){ alert(1); } }); this work, application view or child need have focus. useful, example, if wanted capture key event of input fields.

i've got simple conditional checks if id equal , checks if number. i'm using isnumeric combination of .length. reason isnumeric part not working can enter string of letters , doesn't validate. ideas? var $this = $(this); if(this.id == "username" && $.isnumeric($this.val()).length < 10 ){ //do } the reason you're having problems this: $.isnumeric( $this.val() ) returns true or false , , checking length of boolean makes no sense, true or false never have length on 10, booleans does'nt have length, , returns "undefined" ? maybe meant : if ( this.id == "username" && $.isnumeric( $this.val() ) && $this.val().length < 10 ){ // if value numeric, , string length under 10 }

i looking around solution include line break inside title. normal fixes include actual line break inside code... <div title="ron swanson"></div> or use &#013; in place of new line, so... <div title="ron &#013;swanson"></div> these solutions work fine, since i'm using jade templating engine, can't include line break inside code... .title(title="ron swanson") --or-- .title(title="ron\ swanson") without \ throws syntax error, , doesn't insert line break. `.title(title="ron swanson") prints out characters literally. what correct way of including line breaks in jade templates? i found out can use \n represent new line (just javascript string). doing work... .title(title="ron\nswanson")
