MVC5根据另一个textbox值动态禁用textbox

<input type="text" id="inputValue" />
<input type="text" id="outputValue" disabled />

document.getElementById("inputValue").addEventListener("input", function() {
  var inputValue = document.getElementById("inputValue").value;
  var outputValue = document.getElementById("outputValue");
  
  if (inputValue === "某个特定值") {
    outputValue.disabled = true;
  } else {
    outputValue.disabled = false;
  }
});

[HttpPost]
public ActionResult Index(string inputValue)
{
    string outputValue = string.Empty;
    
    if (inputValue == "某个特定值")
    {
        outputValue = "禁用";
    }
    else
    {
        outputValue = "启用";
    }
    
    ViewBag.OutputValue = outputValue;
    
    return View();
}

<input type="text" id="inputValue" />
<input type="text" id="outputValue" disabled value="@ViewBag.OutputValue" />
