複製代碼代碼如下:
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);
}
}
綁定事件即可調用
