angularjs - Update current model value while using bindings -

-

new angular, hope asking question correctly.

(angular 1.5 , using components)

parent.html:

<names on-refresh-names='$ctrl.reloadnames'></names>

parent.js

this.reloadnames = function() { ... }

names.html

<input ng-model="searchnamevalue"> <button ng-click='$ctrl.onrefreshnames()'></button>

names.js ...

component.bindings = { onrefreshnames: '&' }

i want make input search string cleared (searchnamevalue = '';) when onrefreshnames executed. executed in parent , searchnamevalue in child.

how can that?

you can combine statements 1 expression:

<button ng-click="$ctrl.onrefreshnames(); searchnamevalue = '';"></button>

but in case makes sense move them both function in component controller:

<input ng-model="$ctrl.searchnamevalue"> <button ng-click="$ctrl.onrefresh()"></button>

where in controller

this.onrefresh = function() {   this.onrefreshnames()   this.searchnamevalue = '' }

in case, note in parent view should 

<names on-refresh-names="$ctrl.reloadnames()"></names>

JavaScript - Replace variable from string in all occurrences -

ok, know if have character '-' , want remove in places in string javascript, ... someword = someword.replace(/-/g, ''); but, when applying array of characters, s not working ... const badchars = ('\/:*?"<>|').split(''); let filename = title.replace(/ /g, '-').tolocalelowercase(); (let item = 0; item < badchars.length; item++) { // below not work global '/ /g' filename = filename.replace(/badchars[item]/g, ''); } any ideas? /badchars[item]/g looks badchars , literally, followed i , t , e , or m . if you're trying use character badchars[item] , you'll need use regexp constructor, , you'll need escape regex-specific characters. escaping regular expression has been well-covered . using that: filename = filename.replace(new regexp(regexp.quote(badchars[item]), 'g'), ''); but , don't want that. want character class: let filename = title.replac
