获取未定义引导程序的'无法读取属性'offsetwidth' [英] Getting 'cannot read property 'offsetwidth' of undefined bootstrap
问题描述
我得到了 offsetwidth undefined尽管添加了活动类，并且在我的js函数之上定义了我的jquery。我必须使用旋转木马来完成我的工作，我尝试了一个模拟练习。我的第一个活动图像正在显示，然后在我单击下一步后，我在控制台中收到此错误，图像没有滑动。
I get the offsetwidth undefined in spite of adding active class and also defining my jquery just above my js function. I have to use carousel for my work and I tried a mock one for practice. My first active image is displaying and after I click next I get this error in console and the images are not sliding.

推荐答案
在HTML中更改此行：
Change this line in your HTML:
<div class="item-active">
到
<div class="item active">
该连字符不应存在。如果您需要 item-active 类，请在这两个之后添加，例如< div class =item active item-active> 。 item 和 active 是bootstrap用来运行轮播的类。如果没有第一张幻灯片，你就会收到错误。
That hyphen shouldn't be there. If you need an item-active class, add it after those two, like <div class="item active item-active">. item and active are classes bootstrap uses to run the carousel. Without them on that first slide, you'll get that error.
