我想通過javascript來控制輸入類型按鈕標記的禁用狀態。我使用的瀏覽器是Chrome。我已經做了一個jsfiddle來模擬這個問題，有一個切換按鈕應該在禁用狀態的真實狀態和錯誤狀態之間切換，並且它專門針對停止按鈕。 下面是代碼：啓用或禁用javascript中的按鈕
function toggleState() {
if(document.getElementById("stopButton").disabled){
document.getElementById("stopButton").disabled = "false";
} else {
document.getElementById("stopButton").disabled = "true";
}
