Partial parameters

[tomalex0]

I'm trying to pass parameter from partials and based on that value i wan to do some condition check. This is sample implementation i'm trying to do.

Header Template, header.html

{{#if isleft}}
      {{> leftbtn}}
{{/if}}
      {{title}}

{{#if isright}}
      {{> rightbtn}}
{{/if}}

Handlebars.registerPartial("header",header.html);
Handlebars.registerPartial("leftbtn", "<div>Left</div>");
Handlebars.registerPartial("rightbtn",'<div>Right</div>');

First Approach Is this possible?

  
 newpage1  {{> header {isleft:1,isright : 1} }}
 newpage2  {{> header }}  

Page1 Template, page1.html

 {{> header }}  
 <div>Some Content</div>

Second Approach This worked fine for me

var newpage1  = Handlebars.compile('page1.html')( {isleft:1,isright : 1}) shows both left and right
var newpage2  = Handlebars.compile('page1.html')()  does not shows left and right

Please let me know if first approach is possible and which one is better.

I see where your train of thought is going. My understanding of partials leads me to believe that the partials take their data from the parent context that called them, but I could be wrong. But simple conditionals remove the need to do all that craziness.

Page.html

var page1 = {
    title : "User Profile",
    isLeft : false,
    isRight : false,
    user : {
        name : "Pierce Moore",
        friends : [
            { name : "Nancy", age : 28 },
            { name : "Bobby", age : 25 }
        ]
    }
};

var page2 = {
    title : "Administrator",
    isLeft : true,
    isRight : true,
    user : {
        name : "Pierce Moore",
        friends : [
            { name : "Nancy", age : 28 },
            { name : "Bobby", age : 25 }
        ]
    }
};

$(function() {
    var tpl = Handlebars.compile( templateSelector );
    $("#page1").html(tpl(page1));
    $("#page2").html(tpl(page2));
});

Template.hb

{{#if isLeft}}
    <!-- Left side content -->
{{/if}}

{{#if user}}
    <p>Name: {{user.name}}</p>
    <p>Friends</p>
    <ul>
        {{#each user.friends}}
            <li>Name: {{name}}, age: {{age}}</li>
        {{/each}}
    </ul>
{{/if}}

{{#if isRight}}
    <!-- Right side content -->
{{/if}}

This is going to have the same resolution as #182. My plan is to add support for this syntax {{> foo bar=bat}}.

[jfbrennan]

kpdecker when will {{> foo bar=bat}} be released? need that feature bad!

[kpdecker]

This will land in 2.0. I hope that there will be a prerelease of 2.0 in the
next few weeks, followed by a formal release if no one has major issues
with the upgrade.

I'm not sure if your illustration {{> foo bar=bat}} made it into the release, and if it covers what I'm trying to do. I want to pass a configuration object along with a context object.

{{> myPartial this ../conf}}

Is this possible? Or would there be a way to merge the two objects to make a single context?

[nathagey]

Using a helper worked for this. #182 (comment)

@nathagey you need to be on the 2.x codeline for the native support. That's in alpha right now and not available on all channels.
