Razor syntax inside attributes of html elements (ASP MVC 3)
提问by Martin
I have a table with repeating customer rows, I would like to add the customer ID to the ID attribute of my table rows like this:
我有一个包含重复客户行的表，我想将客户 ID 添加到我的表行的 ID 属性中，如下所示：
<tr id="row<customer id>"></tr>
I try adding this code:
我尝试添加此代码：
@foreach(var c in Model) {
<tr id="[email protected]"></tr>
}
Which gives me the following output:
这给了我以下输出：
<tr id="[email protected]"></tr>
<tr id="[email protected]"></tr>
etc.
等等。
But I would like it to be:
但我希望它是：
<tr id="row1"></tr>
<tr id="row2"></tr>
etc.
等等。
I also tried to add <tr>row@{c.id}</tr>but it did not work..
我也尝试添加<tr>row@{c.id}</tr>但它不起作用..
回答by Buildstarted
have you tried <tr>row@(c.id)</tr>?
你试过<tr>row@(c.id)</tr>吗？
The actual reason why this doesn't work is because your [email protected]matches the regexfor an email address. So the parser assumes it's an email and not actually an attempt to call code. The reason row@{c.id}doesn't work is because the @{}doesn't output and is meant to contain blocks of code.
这不起作用的实际原因是因为您[email protected]匹配了电子邮件地址的正则表达式。所以解析器假定它是一封电子邮件，而不是实际上试图调用代码。原因row@{c.id}不起作用是因为@{}不输出并且旨在包含代码块。
When in doubt you should use @()as it will force what's contained between the ()to be parsed as code.
如有疑问，您应该使用，@()因为它会强制将 之间包含的内容()解析为代码。
