Retrieve Array value by Key

Posted on by CantStopTheFlow 21

arrGods

{

"Love" : "Eros"

"Sea" : "Neptune"

"Slingblade" : "Billy Bob Thorton"

}

 

In Flow, in a Set Variable action, set the variable value to the result of to arrGods["Sea"], which would be "Neptune". 

 

How does one accomplish this in Flow?

    No way. You have to scan all key elements of array.

    By scan, do you mean do an Apply to Each action until the desired key is found?

    I did this, 

    1. Create a strong-typed array (arrArray):

    [
    { "Domain": "Love", "Owner": "Eros" },
    { "Domain": "Sea", "Owner": "Neptune"} ,
    { "Domain":"Slingblade","Owner":"Billy Bob Thorton"}
    ]

     

    2. Make a Filter Array action

    {
        "inputs": {
            "from": "@variables('arrArray')",
            "where": "@equals(item()?['Domain'], 'Sea')"
        }
    }
     
    3. Set Variable action
    {
        "inputs": {
            "name": "strValue",
            "value": "@{outputs('filter_array')['body'][0]['Owner']}"
        }
    }
     
    Now I just need to figure out how to pass in an Array as a parameter, or build it from a text parameter, and then I'll have a global flow to add to my toolbox.

    Yes, correct.
