What is the best way to get and select values from a dropdown list (and also in radio) in Meteor. I have created a helper:
Template.categories.helpers({
categories: ["facebook", "news", "tv", "tweets"]
});
and in html
...
<select class="form-control" id="category">
{{> categories}}
</select>
...
<template name="categories">
<option disabled="disabled" selected="selected">Please Select</option>
{{#each categories}}
<option value="{{this}}">{{this}}</option>
{{/each}}
</template>
In case of edit, I would like to evaluate it with value coming from database (e.g. news) to be selected.
Thanks in advance.
Template HTML:
<select id="category-select">
<option disabled="disabled" selected="selected">Please Select</option>
{{#each categories}}
<option value="{{this}}">{{this}}</option>
{{/each}}
</select>
Template js:
Template.categories.helpers({
categories: function(){
return ["facebook", "news", "tv", "tweets"]
}
});
Template.categories.events({
"change #category-select": function (event, template) {
var category = $(event.currentTarget).val();
console.log("category : " + category);
// additional code to do what you want with the category
}
});
Template.categories.helpers({
categories: function(){
return ["facebook", "news", "tv", "tweets"]
}
});
And you should consider changing template name and helper, they shouldn't be the same.
