我的HTML下划线模板中的代码实际上是打印出来的
"<sup>®</sup>"
而不是商标替换（®）我想要下面的代码。我的代码出了什么问题？编辑：我想将designation.title和designation.description打印到页面，只需用®替换那里的（R）。
<%- designation.title.replace(/(®)/ig, "<sup>®</sup>") %>
<%- designation.description.replace(/(®)/ig, "<sup>®</sup>")%>

您使用的是自动转义为HTML的template function类型： - (BOOL)convertMovieToMP4:(NSString ) originalMovPath andStoragePath:(NSString ) compMovPath

NSURL *tmpSourceUrl = [NSURL fileURLWithPath:originalMovPath];
compMovPath = [compMovPath stringByReplacingOccurrencesOfString:[compMovPath pathExtension] withString:@"mp4"];

[compositionVideoTrack insertTimeRange:CMTimeRangeMake(kCMTimeZero, videoAsset.duration)
ofTrack:clipVideoTrack

[compositionVideoTrack setPreferredTransform:[[[videoAsset tracksWithMediaType:AVMediaTypeVideo] objectAtIndex:0] preferredTransform]];
CGSize videoSize = [[[videoAsset tracksWithMediaType:AVMediaTypeVideo] objectAtIndex:0] naturalSize];
CATextLayer *titleLayer = [CATextLayer layer];
titleLayer.string = @"Ojatro";
titleLayer.font = (_bridge CFTypeRef Nullable)(@"Helvetica");
titleLayer.fontSize = videoSize.height / 8;
titleLayer.shadowOpacity = 0.2;
titleLayer.alignmentMode = kCAAlignmentCenter;
titleLayer.bounds = CGRectMake(0, 0, videoSize.width, videoSize.height / 6);

AVMutableVideoCompositionInstruction *instruction = [AVMutableVideoCompositionInstruction videoCompositionInstruction];

而不是<%-。使用它将导致下划线转义所有内容，以便它可以按原样输出（输出而不被解释为HTML，因此<%变为<，<变为&等
如果要输出原始HTML，只需将&关闭-，但这可能不安全，具体取决于<%-的其余部分以及是否有任何需要转义的字符
答案 1 :(得分：1)
改为使用<%=。

创建一个DOM元素并将其放入其中。在您的情况下，将el对象传递给方法，而不是字符串？
var output = document.getElementsByTagName('div')[0];
var output2 = document.getElementsByTagName('div')[1];
var el = document.createElement( 'div' );
el.innerHTML = "<sup>®</sup>";
var content = document.createTextNode("<sup>®</sup>");
output.appendChild(el);
// this does not work
output2.appendChild(content);<div></div>
<div></div>
