wijmo Module

Contains utilities used by all controls and modules, as well as the Control and Event classes.

Variables

Classes

Interfaces

Enumerations

Functions

Variables

Const changeCulture

changeCulture: Object

Change culture with given code async

param

string (e.g. "jp")

returns

Promise

Const changeCultureSync

changeCultureSync: Object

Change culture with given code synced

param

string (e.g. "jp")

param
returns

void

culture

culture: any

Gets or sets an object that contains all localizable strings in the Wijmo library.

The culture selector is a two-letter string that represents an ISO 639 culture.

Functions

addClass

  • addClass(e: Element, className: string): void

  • Adds a class to an element.

    Parameters

    • e: Element

      Element that will have the class added.

    • className: string

      Class (or space-separated list of classes) to add to the element.

    Returns void

animate

  • animate(apply: IAnimateCallback, duration?: number, step?: number): any

  • Calls a function on a timer with a parameter varying between zero and one.

    Use this function to create animations by modifying document properties or styles on a timer.

    For example, the code below changes the opacity of an element from zero to one in one second:

    import { animate } from '@mescius/wijmo';
const element = document.getElementById('someElement');
animate(pct => {
    element.style.opacity = pct;
}, 1000);

    The function returns an interval ID that you can use to stop the animation. This is typically done when you are starting a new animation and wish to suspend other on-going animations on the same element. For example, the code below keeps track of the interval ID and clears if before starting a new animation:

    import { animate } from '@mescius/wijmo';
const element = document.getElementById('someElement');
if (this._animInterval) {
    clearInterval(this._animInterval);
}
this._animInterval = animate(pct => {
    element.style.opacity = pct;
    if (pct == 1) {
        self._animInterval = null;
    }
}, 1000);

    Parameters

    • apply: IAnimateCallback

      Callback function that modifies the document. The function takes a single parameter that represents a percentage.

    • Optional duration: number

      The duration of the animation, in milliseconds.

escapeHtml

  • escapeHtml(text: string): string

    Returns string

    A RegExp-escaped version of the original string.

evalTemplate

  • evalTemplate(template: string, ctx?: any): string

  • Evaluates a string in template literal notation.

    This function allows you to evaluate template literals on-demand, rather than when they are declared.

    The template string uses the standard template literal syntax, except it is a regular string (enclosed in single or double quotes) rather than a template literal (enclosed in back-quotes).

    The template string may contain references to variables provided in a context object passed as a parameter.

    The template string may contain formatting information as used with the glbz tag function.

    For example:

    import { evalTemplate } from '@mescius/wijmo';
const msg = evalTemplate('hello ${user}, want some ${Math.PI}:n2?', { user: 'Chris' }));
console.log(msg);
> hello Chris, want some 3.14?

    Parameters

    • template: string

      String in template literal notation.

    • Optional ctx: any

      Object with properties acessible to the template.

    Returns string

    A string containing the result.

focusFirst

  • focusFirst(container: HTMLElement, focusableSelector?: string): boolean

  • Moves the focus to the first focusable element within a given container. Optionally, focuses the first element that matches a specific selector. The element would not be focused if it's disabled or it's tabIndex < 0

    Parameters

    • container: HTMLElement

      The DOM element.

    • Optional focusableSelector: string

      Optional. A CSS selector specifying which elements to consider for focusing.

    Returns boolean

    True if an element was focused, otherwise false.

format

  • format(format: string, data: any, formatFunction?: Function): string

  • Replaces each format item in a specified string with the text equivalent of an object's value.

    The function works by replacing parts of the formatString with the pattern '{name:format}' with properties of the data parameter. For example:

    import { format } from '@mescius/wijmo';
let data = { name: 'Joe', amount: 123456 },
    msg = format('Hello {name}, you won {amount:n2}!', data);

    The format function supports pluralization. If the format string is a JSON-encoded object with 'count' and 'when' properties, the method uses the 'count' parameter of the data object to select the appropriate format from the 'when' property. For example:

    import { format } from '@mescius/wijmo';
fmtObj fmt = {
    count: 'count',
    when: {
        0: 'No items selected.',
        1: 'One item is selected.',
        2: 'A pair is selected.',
        'other': '{count:n0} items are selected.'
    }
};
let fmt = JSON.stringify(fmtObj);
console.log(format(fmt, { count: 0 }));  // No items selected.
console.log(format(fmt, { count: 1 }));  // One item is selected.
console.log(format(fmt, { count: 2 }));  // A pair is selected.
console.log(format(fmt, { count: 12 })); // 12 items are selected.

    The optional formatFunction allows you to customize the content by providing context-sensitive formatting. If provided, the format function gets called for each format element and gets passed the data object, the parameter name, the format, and the value; it should return an output string. For example:

    import { format, isString, escapeHtml } from '@mescius/wijmo';
let data = { name: 'Joe', amount: 123456 },
    msg = format('Hello {name}, you won {amount:n2}!', data,
    (data, name, fmt, val) => {
        if (isString(data[name])) {
            val = escapeHtml(data[name]);
        }
        return val;
    }
);

      A composite format string.

    • data: any
