复制代码 代码如下:

function preventAjax(obj,num){

obj.disabled = true;

var num = num;

var types =obj.type;

if(types == 'submit'){

var text = obj.value;

var time1 = setInterval(function(){

obj.value = num;

num--;

if(obj.value <= 0 ){

clearInterval(time1);

obj.disabled = false;

obj.value = text;

}

},1000);

}else{

var text = obj.innerHTML

var time1 = setInterval(function(){

obj.innerHTML = num;

num--;

if(obj.innerHTML <= 0 ){

clearInterval(time1);

obj.disabled = false;

obj.innerHTML = text;

}

},1000);

}

}

绑定事件即可调用

以上就是本文的全部内容了，小伙伴们拿到自己项目中测试下吧。
