convert javascript enum key string to value

rated 0 times [ 144] [ 5] / answers: 1 / hits: 58121 / 8 Years ago, sat, september 17, 2016, 12:00:00

In JavaScript code, I have the following enum defined:

MyMessageIds = {

    UndefinedId : 0,

    FilenameId : 1,

    BuildFileId : 2,

    MovementArgsId : 3,

    MoveId : 4,

    ExecuteCommandId : 5

}

In a JavaScript function, I would like to be able to supply the string representation of an enum key (i.e. MoveId) and return its integer value of 4. So how could I do this?

Just use bracket notation:

var MyMessageIds = {

    UndefinedId : 0,

    FilenameId : 1,

    BuildFileId : 2,

    MovementArgsId : 3,

    MoveId : 4,

    ExecuteCommandId : 5

};



function getValue(key) {

    return MyMessageIds[key];

}
