Javascript - Radio Button Enable/disable Elements Not Right

So i'm trying to make enable/disabled elements based on the checked radio button in the edit form. When I try to run the code and test the form, it looks kinda funny. I don't know

Solution 1:

Try rewrite it without recursion, try-catch and setting disabled for specific div classes using querySelector(). https://jsfiddle.net/Lsre6mfL/

You can also fold

var divis_el = document.getElementById("division");
for (var i = 0; i < divis_el.children.length; i++) {
    divis_el.children[i].disabled = true;
}

In function.

Solution 2:

Wow, look how simple it is.

function toggleAlert2() {
    document.getElementById("extText").disabled = false;
    document.getElementById("client_details").disabled = true;
    document.getElementById("client_details1").disabled = true;
    
}

function toggleAlert() {
    document.getElementById("extText").disabled = true;
    document.getElementById("client_details").disabled = false;
    document.getElementById("client_details1").disabled = false;
}

    <form method="post" action="" enctype="multipart/form-data">
        ID: 50<br>
        <input type="hidden" name="id" value="50" />

        <label for = "client1">
        <input type="radio" name="client_type" id = "client1" value="Division" checked onchange="toggleAlert()"/> Division
        </label>
        &nbsp &nbsp &nbsp &nbsp &nbsp &nbsp &nbsp &nbsp &nbsp &nbsp &nbsp &nbsp &nbsp &nbsp &nbsp &nbsp &nbsp &nbsp &nbsp 
        <label for ="client2">
        <input type="radio" name="client_type" id = "client2" value="External"  onchange="toggleAlert2()"/> External
        </label>
        &nbsp 
        <input type="text" id="extText" name="client_details2" value="rrrrrr"/> 
        <br><br>

        <div id="division">
        Division:
        <select id="client_details" name="client_details">
            <option value="Choose"  />Choose Division...</option>
            <option value="Distribution"  />Distribution</option>
            <option value="Transmission"  />Transmission</option>
            <option value="Generation"  />Generation</option>
            <option value="Procument"  />Procument</option>
            <option value="Other"  />Others</option>
        </select>   
        <br><br>
        Others:<input id="client_details1" type="text" name="client_details1" value="rrrrrr" />
        <br>
        </div>
        <br>
        <input type="submit" name="submit" value="Submit"/>
    </form>
