ページボタンの繰り返し送信を避けるための JavaScript の実装_JavaScript スキル

复制代 代码如下:

関数PreventAjax(obj,num){
            obj.disabled = true;
            var num = num;
            var タイプ =obj.type;
            if(types == 'submit'){
                var text = obj.value;
                var time1 = setInterval(function(){
                    obj.value = num;
                    num--;
                    if(obj.value                         clearInterval(time1);
                        obj.disabled = false;
                        obj.value = テキスト;
                    }
                },1000);
            }その他{
                var text = obj.innerHTML
                var time1 = setInterval(function(){
                    obj.innerHTML = num;
                    num--;
                    if(obj.innerHTML                         clearInterval(time1);
                        obj.disabled = false;
                        obj.innerHTML = テキスト;
                    }
                },1000);
            }
        }

決定イベント即可
