Vuejs 2

Cheatsheet

Components understanding:

Preventing easy:

    <a href="#" @click.prevent="toDo();"></a>

Easy event handling:

    <button @click.ctrl="onClick">A</button>

    <button @click.ctrl.exact="onCtrlClick">A</button>

Prop validation:


    Vue.component('example', {
      props: {
        // basic type check (`null` means accept any type)
        propA: Number,
        // multiple possible types
        propB: [String, Number],
        // a required string
        propC: {
          type: String,
          required: true
        },
        // a number with default value
        propD: {
          type: Number,
          default: 100
        },
        // object/array defaults should be returned from a
        // factory function
        propE: {
          type: Object,
          default: function () {
            return { message: 'hello' }
          }
        },
        // custom validator function
        propF: {
          validator: function (value) {
            return value > 10
          }
        }
      }
    })

Mixins:


require('myapp-bootstrap');

require('./components/bootstrap');

var app = new Vue({
    mixins: [require('myapp')]
});


module.exports = {
    el: '#myapp-app',

    /**
     * The application's data.
     */
    data: {

    },
}

LibreOffice Calc Hints

How to swap a column in Calc:

Select column B

Click anywhere in the highlighted area and drag the column. The mouse pointer should change to show the drag operation.

Before you release the mouse button, also press the Alt key. When the mouse pointer is at the left side of column A, release the mouse button.

Column B should be moved to the left of column A so that A and B are switched.
