UdeS.FunctionsMixins

This repository provides useful functions to help you create faster your Polymer applications and components.

In Polymer, when we want to use a dom-if, we should provide it a boolean property. However, when we want to provide the result of a function, we must define that function inside our element, even if that function is simple as note > 60 by example.

By using the UdeS.FunctionsMixins, you no longer need to create and maintain theses custom functions. You could simply write your dom-if as below:

<template is="dom-if" if="[[greaterThan(note, 60)]]">
</template>

Mixins

Base mixins

• UdeS.ArrayFunctionsMixin

  • array Return an array of arguments.
  • at Return the element of array at the specified index.

• EqualityOperatorsMixin

  • equal Perform a comparison (a == b) on all arguments.
  • strictEqual Perform a strict comparison (a === b) on all arguments.
  • notEqual Perform a comparison (a != b) on all arguments.
  • notStrictEqual Perform a strict comparison (a !== b) on all arguments.

• UdeS.IsFunctionsMixin

  • isAllUndefined Check if the all variables are undefined.
  • isArray Check if the variable is an array.
  • isEmptyArray Check to see if an array is empty.
  • isEmptyObject Check to see if an object is empty (contains no enumerable properties).
  • isEmptyString Check to see if a string is empty.
  • isInteger Check to see if a string is an integer.
  • isPositiveInteger Check to see if a string is a positive integer.
  • isUndefined Check if at least one variable is undefined.
  • isUndefinedVariable Check if the variable is undefined.

• UdeS.LogicalOperatorsMixin

  • and And function (&&).
  • iif If function.
  • not Not function (!).
  • or Or function (||).
  • xor Exclusive or function.
