I am a new guy in Meteor. I have select box which i want to populate from the mongo collection itself.I tried doing this as below but doesn't work
<template name="clist">
<div class="input-field">
<select>
<option value="" disabled selected>Choose your option</option>
{{#each company}}
<option>{{ccategory}}</option>
{{/each}}
</select>
</div>
<ul class="collection" id="listings">
{{#each company}}
<li>
{{> employees}}
</li>
{{/each}}
</template>
And also i want to filter the data in mytemplate according to the value selected in the dropdownlist. Please help me iam stuck in this.
this is exactly what i have now but the problem is the dropdownlist is populating based on the results of all the listings not directly from the schema and is repetitive of all values. and i am using the same returning helper for both these values like return company.find(). Please help me
Well in order to populate the select, you should change the {{#each}} down to the select, like this.
<select>
<option disabled selected>Choose option</option>
{{#each company}}
<option>{{category}}</option>
{{/each}}
</select>
Because if you put the {{#each}}
at the top of the <select>
tag meteor will create 1 select for each company.
And the company helper should be simple like a simple return company.find();
Now if you want to filter, there are many options to accomplish this, one could be this.
I like to use ReactiveDict(); , so i will use on this example.
Install it meteor add reactive-dict
Template.example.onCreated(function(){
var self = this;
self.example = new ReactiveDict();
self.example.setDefault( 'valueToFilter' , null);
});
Now on some event like change
, do the following.
Template.example.events({
'change select' : function( event, template ) {
var instance = Template.instance();
instance.example.set( 'valueToFilter' event.target.value ); //or use $('select').val() whatever you like to take the value;
}
})
Now show the results.
Template.example.helpers({
showSelectedValues : function(){
var instance = Template.instance();
return Companies.find( { name : instance.example.get( 'valueToFilter' )} );
}
})
This should give you a big picture, good luck!
