如何使用 setInterval() 在另一个 function 中定期调用单击 function?

[英]How to use setInterval() to call a click function periodically within another function?

this is my first programming in Java.这是我在 Java 中的第一次编程。 I have two functions, #start and #reset.我有两个函数,#start 和#reset。 I want to use setInterval to use #reset function within #start after every 10 seconds.我想使用 setInterval 在每 10 秒后的 #start 内使用 #reset function 。

Here are the two functions.这是两个函数。 First is #start首先是#start

$('#start').click(function() {

    // Calculate the amount of time in milliseconds to run for
    var timeleft_s = Math.round(
        parseInt($('#hours'  ).val())*3600 +
        parseInt($('#minutes').val())*60 +
        parseInt($('#seconds').val())*1
    );

    if (timeleft_s > 2147483647) { // Max unsighed 32 bit value
        alert("That's too long. Pick a shorter time.");
        return;
    }

    if (APP.last_sent_status !== null && APP.last_sent_status !== APP.status) {
        return false;
    }

    // 0 : not started
    // 1 : running
    // 2 : stopped
    switch(APP.status) {
        case 0:
            APP.resumeMCA(APP.channel, timeleft_s);
            APP.last_sent_status = 1;
            break
        case 1:
            APP.stopMCA(APP.channel);
            APP.last_sent_status = 2;
            break
        case 2:
            APP.resumeMCA(APP.channel, timeleft_s);
            APP.last_sent_status = 1;
            break
        default:
            break
    }
    APP.updateButtonStates();
});

Here is the reset function这是重置 function

    $('#reset').click(function() {
    APP.resetHistogram(APP.channel);
});

I want to use setInterval inside the start function make sure the reset function executes after every 10 seconds.我想在 start function 中使用 setInterval 确保每 10 秒后执行一次重置 function。

Here is what I have tried so far with no luck.这是我到目前为止没有运气的尝试。 Any help is appreciated:任何帮助表示赞赏:

$('#start').click(function() {

    // Calculate the amount of time in milliseconds to run for
    var timeleft_s = Math.round(
        parseInt($('#hours'  ).val())*3600 +
        parseInt($('#minutes').val())*60 +
        parseInt($('#seconds').val())*1
    );

    if (timeleft_s > 2147483647) { // Max unsighed 32 bit value
        alert("That's too long. Pick a shorter time.");
        return;
    }

    if (APP.last_sent_status !== null && APP.last_sent_status !== APP.status) {
        return false;
    }

    // 0 : not started
    // 1 : running
    // 2 : stopped
    switch(APP.status) {
        case 0:
            APP.resumeMCA(APP.channel, timeleft_s);
            APP.last_sent_status = 1;
            break
        case 1:
            APP.stopMCA(APP.channel);
            APP.last_sent_status = 2;
            break
        case 2:
            APP.resumeMCA(APP.channel, timeleft_s);
            APP.last_sent_status = 1;
            break
        default:
            break
    }

 setInterval(#reset,10000)

    APP.updateButtonStates();
});
function resetFunction(){
 APP.resetHistogram(APP.channel);
}

$('#reset').click(resetFunction);

then replace然后替换

setInterval(#reset,10000) with setInterval(resetFunction,10000) setInterval(#reset,10000)setInterval(resetFunction,10000)

since you defined the function to be called on #reset click as anonymous there's no reference as such by which you can call it.由于您将 function 定义为在#reset单击时以匿名方式调用,因此没有可以调用它的参考。

so you define it by giving it a name, and then use that in place of onclick function as well as inside your start function所以你通过给它一个名字来定义它,然后用它代替 onclick function 以及你的 start function

I am not totally sure of this answer.我不完全确定这个答案。 If you are trying to start a setInterval inside of the onclick of #start , here's what I think you could do:如果您尝试在#start onclick启动setInterval ,我认为您可以这样做:

 setInterval($("#reset").onclick(),10000);
