I’m currently building a nifty little ‘talent point distributor’ view, similar to what popular RPG games offer. I didn’t want a huge wall of HTML code for all the buttons and textboxes, so I created a template to which I pass two parameters:
- the name of the stat I want to alter
- the initial value of the stat
The template renders correctly, and I notice that when I log the results to the console, the variable seems to be changed correctly. However, the displayed value does not change and will always stay at 0.
Here is the template itself:
<template name="attributeStepper">
<div class="row" style="margin: 1em;">
<div class="col-sm-3 col-md-2">
<h4>{{toUpper attribute}}</h4>
</div>
<div class="col-sm-6 col-md-4">
<div class="btn-group" role="group">
<button type="button" class="btn btn-default btn-value-dec">
<span class="glyphicon glyphicon-chevron-down"></span>
</button>
<button type="button" class="btn btn-default disabled">{{attributeValue}}</button>
<button type="button" class="btn btn-default btn-value-inc">
<span class="glyphicon glyphicon-chevron-up"></span>
</button>
</div>
</div>
</div>
</template>
Here is the helper I defined for the template:
Template.attributeStepper.helpers({
toUpper : function(str) {
return str.substring(0, 1).toUpperCase() + str.substring(1);
}
})
Template.attributeStepper.events({
'click .btn-value-inc' : function(event, tmpl) {
tmpl.data.attributeValue ++;
},
'click .btn-value-dec' : function(event, tmpl) {
tmpl.data.attributeValue --;
}
});
And this is how I call the templates from the actual view:
<div class="panel panel-default">
<div class="panel-heading">
<h3 class="panel-title">Attributes</h3>
</div>
{{ >attributeStepper attribute="strength" attributeValue="0"}}
{{ >attributeStepper attribute="courage" attributeValue="0"}}
{{ >attributeStepper attribute="intelligence" attributeValue="0"}}
{{ >attributeStepper attribute="agility" attributeValue="0"}}
{{ >attributeStepper attribute="dexterity" attributeValue="0"}}
{{ >attributeStepper attribute="intuition" attributeValue="0"}}
{{ >attributeStepper attribute="charisma" attributeValue="0"}}
</div>
I hope you can make any sense out of this and tell me what I’m doing wrong, because I feel like I’m not following the mindset behind Meteor correctly yet.
Cheers!
