Store Dropdown License For Free

You have a few options with regard to how you can store the individual data elements corresponding to the list elements in the options value attribute. Use array indices. Transform your data into an object keyed on the name and look it up from that. Convert the data to json and store it in the value attribute.

Populating dropdown options from the json. (Value is Integer, Text is Text) ... Next, you use JSON Deserialize to deserialize the JSON: (Note that the "JSON" variable here is a stand-in for wherever you receive the JSON from.) ... On your screen, you assign the variable to the List of the Dropdown:

Let myObj = { name: "Chris", age: 38 }; myObj; let myString = JSON.stringify(myObj); myString; Here we're creating a JavaScript object, then checking what it contains, then converting it to a JSON string using stringify() ? saving the return value in a new variable ? then checking it again.

Assuming plain javascript, try the following in a script placed after the dropdown: const mySel = document.getElementById("theIDofYourSelect"); mySel.addEventListener("change",function() { localStorage.setItem("selValue",this.value); // save it. }); let val = localStorage.getItem("selValue");
