jQuery-可变增量+1 [英] jQuery - Variable Increment +1

问题描述

我看了一眼，我有些困惑.

I've had a look round and I'm a little confused.

对于我的特定问题似乎有几种回答，但我并不完全理解.

There seems to be several responses to my particular problem but I don't fully understand.

因此，如果有人可以帮助，那就太好了！

So if anybody could help that'd be great!

基本上，我设置了一个变量

var firstThumb = "02"   

并且我想增加它

function thumbIncrease() {
            firstThumb++
        };

每隔一段时间

setInterval(function(){
            getThumb.trigger("click");
            thumbIncrease();
        }, 5000);

基本上我希望发生的是- 每5秒钟触发一次点击，我希望我的firstThumb变量增加1.

Basically what I expect to happen is - Every 5 seconds a click is triggered, and I want my firstThumb variable to increase by 1.

所以02，单击，03，单击，04，单击....

So 02, click, 03, click, 04, click....

因此，每次单击不同的元素.

So each time it clicks a different element.

任何帮助都会很棒！

谢谢！

感谢您的答复！我现在明白了！因此，我得到0的原因，对我而言，比对代码而言更重要.我目前有15件事需要点击. 01和15是2个字符，这意味着我的代码看起来更整洁.我应该手动删除0吗?还是有更好的方法呢?

Thanks for the responses! I kind of understand now! So the reason I've got a 0, is more for me than for the code. I currently have 15 things that I need clicking. 01 and 15 being 2 characters, meaning my code looks neater. Should I just man up and remove the 0? Or is there a better way of doing it?

推荐答案

var counter = 1;

setInterval(function() {

  var _text = counter + "<br>";

  $("div").append(_text);

  counter++;   
   
},5000);

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<div>
</div>

如果要替换旧数字，请使用.html()代替.append()

If you want it to replace the old number use .html() instead of .append()

"01"是字符串，1是可以递增的数字.

"01" is a string, 1 is a number you can increment.
