我找不到解决此错误的方法。
中有此代码
我的模型MultimediaLanguageEdit.cs
public class MultimediaLanguageEdit
{
//[RegularExpression(@"((?<=^https?://(www\.)?youtube\.com/.*v=)\w+)|((?<=^https?://youtu\.be/)\w+)|((?<=src=""https?://(www\.)?youtube\.com/v/)\w+)|((?<=src=""https?://(www\.)?youtube\.com/embed/)\w+)",
[RegularExpression(@"(^https?://(www\.)?youtube\.com/.*v=\w+)|(^https?://youtu\.be/\w+)|(src=.https?://(www\.)?youtube\.com/v/\w+)|(src=.https?://(www\.)?youtube\.com/embed/\w+)",
ErrorMessageResourceType = typeof(ErrorMessages),
ErrorMessageResourceName = "FieldRegExp")]
public string Text { get; set; }
}
，视图
MultimediaLanguageEdit.cshtml
@model MultimediaLanguageEdit
<div class="editor-label">
@Html.LabelFor(m => m.Text, "Codice HTML:")
</div>
<div class="editor-field">
@Html.TextAreaFor(m => m.Text)
@Html.ValidationMessageFor(m => m.Text)
</div>
中有此代码，并且该字段始终无效 对于所有此案例测试
并匹配此测试用例
但如果我在 自定义编辑器甚至在控制器中，我对每种情况都有一个匹配。
这段代码有什么问题？
I can't find a way to get through this error.
I've got this code in my model
MultimediaLanguageEdit.cs
public class MultimediaLanguageEdit
{
//[RegularExpression(@"((?<=^https?://(www\.)?youtube\.com/.*v=)\w+)|((?<=^https?://youtu\.be/)\w+)|((?<=src=""https?://(www\.)?youtube\.com/v/)\w+)|((?<=src=""https?://(www\.)?youtube\.com/embed/)\w+)",
[RegularExpression(@"(^https?://(www\.)?youtube\.com/.*v=\w+)|(^https?://youtu\.be/\w+)|(src=.https?://(www\.)?youtube\.com/v/\w+)|(src=.https?://(www\.)?youtube\.com/embed/\w+)",
ErrorMessageResourceType = typeof(ErrorMessages),
ErrorMessageResourceName = "FieldRegExp")]
public string Text { get; set; }
}
and this code in my View
MultimediaLanguageEdit.cshtml
@model MultimediaLanguageEdit
<div class="editor-label">
@Html.LabelFor(m => m.Text, "Codice HTML:")
</div>
<div class="editor-field">
@Html.TextAreaFor(m => m.Text)
@Html.ValidationMessageFor(m => m.Text)
</div>
and the field is always invalid for all this case test

<iframe width="560" height="315" src="http://www.youtube.com/embed/tYTIo6H19uw" frameborder="0" allowfullscreen></iframe><object width="560" height="315">
<param name="movie" value="http://www.youtube.com/v/tYTIo6H19uw?version=3&hl=it_IT"></param><param name="allowFullScreen" value="true"></param>

</object>
and match this test case
but if I test the the regex in a custom editor or even in a controller, I've a got a match for every case.
What is wrong with this code?

正确的 RegExp 是
因为 javascript 检查 RegExp 的整行并期望从头到尾正确匹配。
The correct RegExp is
Because javascript check the whole line of RegExp and expect a correct match from the beginning to the end.
