Try:
尝试：
<% if (x == 0) { %>
<script type="text/javascript">blob("sometext");</script>
<% } %>
Since the Javascript needs to be put on the page, you need to close off the <% %>tags so that you can print HTML. The specific HTML needs to be a <script>tag that calls the function you need.
由于需要在页面上放置 Javascript，因此您需要关闭<% %>标签，以便您可以打印 HTML。特定的 HTML 需要是一个<script>调用你需要的函数的标签。

I know that you're not using Razor (because of your code sample), but if you want to use it at some time, you can do it like this
我知道你没有使用 Razor（因为你的代码示例），但如果你想在某个时候使用它，你可以这样做
@if (x == 0)
{
<text>
<script type="text/javascript">blob("sometext");</script>
</text>
}
or
或者
@if (x == 0)
{
@: <script type="text/javascript">blob("sometext");</script>
}
