答案 0 :(得分:0)
在你的HTML中把它放在某个地方
在你的javascript中:
var secondstildone = 3; var intervalVariable;
function wifioff(){
$("#errorImg).attr("src", "Images/errorImg.png");
var f = DoTimerStuff;
intervalVariable = setInterval(f, 1000);
}
DoTimerStuff() {
secondstildone--;
if(secondstildone <= 0){
$("#errorImg).attr("src", "");
clearInterval(intervalVariable);
}
}
