The conversion method of string translation using the dictionary in JavaScript.
This example describes how to convert strings by using dictionaries in JavaScript. Share it with you for your reference. The specific analysis is as follows:
In fact, this is to first set a dictionary for comparison, and then find the corresponding key value from the dictionary through the translation function. It must be used in JavaScript 1.8 or later versions.
The function is defined as follows:
Function CreateTranslator (translationTable) function (s) s. replace (new RegExp ([k for (k in translationTable)]. join ('|'), 'G'), function (str) translationTable [str]);
Call method:
Var translationTable = {a: 1, bb: 2, B: 3, c: 4}; var MyTranslater = CreateTranslator (translationTable); MyTranslater ('aabbbc '); // returns: 11234
