将Razor数据插入src和href属性

Question

I need to insert an API key and a location string into the src attribute of my iframe element.

This is how my iframe looks atm:

<iframe class="center-block" src="https://www.google.com/maps/embed/v1/place?key=@Umbraco.Field('aPIKey')&q=@Umbraco.Field('lokation')" width="95%" height="300" frameborder="0" style="border:0" allowfullscreen></iframe>

But when i go to the page, i get this error:

Too many characters in character literal

I tried using "" instead for the razor properties, but that destroys the formatting for the rest of the dokument.

I'm just really confused as to what is the correct way to use Razor syntax inside HTML attributes.

Answer 1

@Umbraco.Field('lokation') @Umbraco.Field('aPIKey')

should be

@Umbraco.Field("lokation") @Umbraco.Field("aPIKey")

The ' quote is used for character literals in c#

Now because you are using " quotes in razor you will need to change the html quotes to be ' .

<iframe class="center-block" src='https://www.google.com/maps/embed/v1/place?key=@Umbraco.Field("aPIKey")&q=@Umbraco.Field("lokation")' width="95%" height="300" frameborder="0" style="border:0" allowfullscreen></iframe>

Answer 2

它应该是@(Umbraco.Field("lokation")) -如果您的“变量”包含括号或其他特殊字符，例如“，当您已经在以“”分隔的文本字符串中时，则需要将整个内容括起来在...更多的寄生虫:-)
