How to create a global variable and change in multiple places in golang html/template?

<p>I am creating a variable in html/template and and changing the value based on a condition. But the scope of the value stays only inside the if condition</p> <pre><code> {{if .UserData}} {{$currentUserId := .UserData.UserId}} [&lt;a href=&#34;#ask_question&#34;&gt;Inside loop {{$currentUserId}}&lt;/a&gt;] {{else}} {{$currentUserId := 0}} {{end}} [&lt;a href=&#34;#ask_question&#34;&gt;outside {{$currentUserId}}&lt;/a&gt;] </code></pre> <p>Inside the if condition I am getting the correct value but outside it is 0. How can I use the $currentUserId outside the condition. Could someone help me with this?</p> <hr/>**评论：**<br/><br/>justinisrael: <pre><p>There is a similar discussion back from 2013: <a href="https://groups.google.com/d/topic/golang-nuts/MUzNZ9dbHrg/discussion" rel="nofollow">https://groups.google.com/d/topic/golang-nuts/MUzNZ9dbHrg/discussion</a></p> <p>tl;dr You can reassign the variable within the same scope, but not from another scope. And you can do this logic ahead of time and precompute it into your context.</p></pre>dineshappavoo: <pre><p>@justinisrael - It is really helpful. </p></pre>
