javascript - restore dropdown selection after refresh local storage

Question

I am trying to save an options tag value to local storage. After saving its value to local storage I would like to be able to set the options tag to the option the user selected. I have tried the follow, but I am only able to save the value. I have trouble changing the select tag to the users selected value.

<select name="fruit" id="fruit">
    <option value="1">Apple</option>
    <option value="2">Guava</option>
    <option value="3">Mango</option>
    <option value="4">Grapes</option>
</select>

document.getElementById("fruit").onchange = function() {
 localStorage.setItem('fruit', document.getElementById("fruit").value);
}

if (localStorage.getItem('fruit') === "Guava") {
 document.getElementById("fruit").setAttribute('Selected', 'Guava');
}

Answer 1

Its because your values and text are different for your select options. Try:

 <select name="fruit" id="fruit">
    <option value="Apple">Apple</option>
    <option value="Guava">Guava</option>
    <option value="Mango">Mango</option>
    <option value="Grapes">Grapes</option>
</select>

    document.getElementById("fruit").onchange = function() {
     localStorage['fruit'] = document.getElementById("fruit").value;
    }
    window.onload= function(){
        if(localStorage['fruit'])
            document.getElementById("fruit").value = localStorage['fruit'];
    }
