车把在条件中定义{{with}}

Question

I want to show a different content from my json in my template depending of a javascript defined variable.

Here is the JSON file :

{
"normal" :{
    "content":"content"
}
"expert" :{
    "content":"content"
}

[HTML] Now in my template, I have this :

{{#with normal}}
    <p>{{content}}</p>
{{/with}}

Now I want to be able to use 'with normal', or 'with expert' depending of a javascript-side defined variable.

I have made a compare helper but, I have to use the code twice and that's ugly. So Maybe someone know how to do it properly ? Thanks.

Answer 1

Do you really need logic in your template?

If the body of the {{#with}} block is identical for data of normal or expert types, then you can probably get rid of the with entirely and pass the appropriate block into the template. This pushes the logic back into the script (and hopefully the view, if you have an MVC framework), which is good, and optimizes out a level of the template (also good, especially since that is a with , which tend to be slow).

Note that Handlebars is perfectly happy taking an object with more data than it needs, so writing a template that depends on the normal block and passing the expert with additional details (presumably) will cause no problems at all.

您可以使用{{#if和else...。此外，还可以使处理程序成为全局处理程序并使用两次。
