提问by Modelesq
I'd like to show a random numbers within my list. Im grabbing the list from the backend, and im just using these numbers as examples. This is my code, I'm not quite sure why its not filling in the text.
我想在我的列表中显示一个随机数。我从后端获取列表，我只是使用这些数字作为示例。这是我的代码，我不太确定为什么不填写文本。
setInterval(function() {
var number = 1 + Math.floor(Math.random() * 6);
$('.num-gen').text(number);
},
Made a fiddle hereto show you what I'm working with. Thanks in advance.

You had an error in your code, you were missing the finishing , 1000/*time in ms*/);!
你的代码有错误，你错过了整理, 1000/*time in ms*/);！
Also, jQuery is not required here, you may do this in Javascript like this.
此外，这里不需要 jQuery，您可以像这样在 Javascript 中执行此操作。
setInterval(function() {
var number = 1 + Math.floor(Math.random() * 6);
document.getElementsByClass('num-gen')[0].innerHtml = number;
}, 1000);
EDIT:
编辑：
setInterval(function() {
jQuery.each(jQuery('.num-gen'),function(){
var number = 1 + Math.floor(Math.random() * 6);
jQuery(this).text(number);
});
}, 1000);

您的代码中有语法错误，请将其更改为：
setInterval(function() {
var number = 1 + Math.floor(Math.random() * 6);
$('.num-gen').text(number);
}, 10);
