[英]how to stop Javascript function execution?
My program has two buttons. 我的程序有两个按钮。 One is for execute other program by using jquery load function. 一种是通过使用jquery加载功能来执行其他程序。 Whenever I click execute button, it runs some other program abc.php
using load function for n times, with some time gap like k mins. 每当我单击“执行”按钮时,它都会使用加载功能运行其他程序abc.php
达n次,间隔为k分钟。 These n and k will be filled with html inputs. 这些n和k将用html输入填充。 Using jquery, will retrieve these and passing to that program file in url. 使用jquery,将检索这些并将其传递到URL中的该程序文件。
To call this function setTimeout
was used. 为了调用此函数,使用了setTimeout
。
Second one is for cancel execution. 第二个是取消执行。
Now my doubt is, suppose I want to stop that execution with cancel button. 现在我的疑问是,假设我想使用“取消”按钮停止执行。 Is there any way to stop it ? 有什么办法阻止它吗?
I would do this using boolean
variable. 我会使用boolean
变量来做到这一点。
For example: Consider a method, perform logging. 例如:考虑一种方法,执行日志记录。
fun () {
console.log("prints");
}
I would change it has 我会改变它
fun (isExecute) {
if (isExecute) {
console.log("prints");
}
}
Run fun (true);
运行 fun (true);
cancel fun (false);
取消 fun (false);
It seems you use setTimeout()
, then it is too easy without above approach. 似乎您使用setTimeout()
,那么如果没有上述方法,那就太容易了。
Run var inter = setTimeout(fun);
运行 var inter = setTimeout(fun);
cancel clearTimeout(inter);
取消 clearTimeout(inter);
FYI: The reason for assigning to a variable inter
is then only you can clear this time interval. FYI:之所以赋值给一个变量inter
是那么只有你可以清除该时间间隔。
set time for function: 设置功能时间:
timer = setTimeout(function(){$('#submenu').hide();},5000);
stop a function 停止功能
clearTimeout(timer);
