Methods

Properties

culture

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.

Type
any

Methods

addClass

addClass(e: HTMLElement, className: string): void

Adds a class to an element.

Parameters
  • e: HTMLElement

    Element that will have the class added.

  • className: string

    Class to add to the element.

Returns
void

animate

animate(apply: Function, duration?: number, step?: number): number

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:

var element = document.getElementById('someElement');
animate(function(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:

var element = document.getElementById('someElement');
if (this._animInterval) {
  clearInterval(this._animInterval);
}
var self = this;
self._animInterval = animate(function(pct) {
  element.style.opacity = pct;
  if (pct == 1) {
    self._animInterval = null;
  }
}, 1000);
Parameters
  • apply: Function

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

  • duration: number Optional

    The duration of the animation, in milliseconds.

  • step: number Optional

    The interval between animation frames, in milliseconds.

escapeHtml

escapeHtml(text: string): void

Escapes a string by replacing HTML characters as text entities.

Strings entered by uses should always be escaped before they are displayed in HTML pages. This ensures page integrity and prevents HTML/javascript injection attacks.

Parameters
  • text: string

    Text to escape.

Returns
void

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:

var data = { name: 'Joe', amount: 123456 };
var msg = wijmo.format('Hello {name}, you won {amount:n2}!', data);

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:

var data = { name: 'Joe', amount: 123456 };
var msg = wijmo.format('Hello {name}, you won {amount:n2}!', data,
            function (data, name, fmt, val) {
              if (wijmo.isString(data[name])) {
                  val = wijmo.escapeHtml(data[name]);
              }
              return val;
            });
