Use a CustomAttribute to replace elements entire content - Aurelia -


i'm using customattribute on <th> add column ordering table.

i've achieved using following in custom attribute vm;

import {bindable, inject, observable, container, viewengine, viewslot, bindingmode} 'aurelia-framework';  @inject(element, container, viewengine) export class ordercustomattribute {     @bindable key;     @bindable @observable orderby;     @bindable @observable orderdirection;     mydirection = false;      constructor(element, container, viewengine){         this.element = element;         this.viewengine = viewengine;         this.container = container;     }      attached() {         this.viewengine.loadviewfactory('components/datatable/attributes/order.html').then(factory => {              const childcontainer = this.container.createchild();             const view = factory.create(childcontainer);              view.bind(this);             const vs = new viewslot(this.element, true);             vs.add(view);              this.updatecaret();         });     }      order() {         if(this.key == this.orderby) {             // we're ordering column, move order on one;             if(!this.orderdirection) {                 this.orderdirection = "asc";             } else if(this.orderdirection == "asc") {                 this.orderdirection = "desc";             } else {                 this.orderdirection = false;                 this.orderby = false;             }         } else {             // we're not ordering column, lets start doing             this.orderby = this.key;             this.orderdirection = "asc";         }     }      orderbychanged(newvalue, oldvalue) {         this.updatecaret();     }      orderdirectionchanged(newvalue, oldvalue) {         this.updatecaret();     }      updatecaret() {         if(this.key == this.orderby) {             this.mydirection = this.orderdirection;         } else {             this.mydirection = false;         }     } }

and simple view;

<template>     <a class="order__icon" click.delegate="order()">         <i class="fa fa-caret-down" show.bind="mydirection == 'desc'"></i>         <i class="fa fa-caret-up" show.bind="mydirection == 'asc'"></i>         <i class="fa fa-caret-up text-muted" show.bind="!mydirection"></i>     </a> </template>

i've written straightforward logic sort data when sort icon clicked.

the issue i'm having want whole of column heading link, not icon. code above adds customattribute vm element. there way can;

  1. get contents of element (so, column name)
  2. use these contents in view
  3. replace contents of element view (rather appending view element)

vue.js - Create hooks for automated testing -

qa guys complained can't automate frontend testing. because our html looks same outside. lazy hack did this <template> <div :role="$options.name"> ... </div> </template> <script> export default { name: 'vmcomponentname' } </script> which takes name script , applies html. in browser get: <div role="vmcomponentname"> ... </div> line :role="$options.name" goes in every component. is there dry er solutions? please share. additional details i'll explain in details looking for. imagine have vmusercreate form creates user. test case can create user . to automatically test without role, have use following selector: .wrapper > .wrapper > .wrapper > .submit-button the test extremely brittle (will break lot). if use roles can use [role="vmusercreateform"] .submit-button selector. many folds less brittle. so basically, i'm ...
