Question

Random Character example是指向我网页图片的链接。我找不到＆gt;的位置生成页面底部的符号。我已经使用cmd f来搜索代码中的随机代码，似乎都没有放错位置。尽管如此，它并不是非常具有侵入性，我喜欢理解我的代码。

另外，我不明白为什么我的for循环没有激活。

Answer 1

就在卡片交易代码之上，还有额外的“＆gt;”在评论的二十一点任务中。希望它会有所帮助

Answer 2

在第77行，评论中有一个额外的/** * Marks all controls in a form group as touched * @param formGroup - The form group to touch */ private markFormGroupTouched(formGroup: FormGroup) { (<any>Object).values(formGroup.controls).forEach(control => { control.markAsTouched(); if (control.controls) { this.markFormGroupTouched(control); } }); }：

以

运行

＆GT;
