流星下拉列表获取并设置 [英] Meteor Dropdown list get and set

问题描述

在Meteor中从下拉列表(以及在广播中)中获取和选择值的最佳方法是什么. 我创建了一个助手:

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"]
});

和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>

在进行编辑的情况下，我希望使用来自数据库(例如新闻)的值进行评估.

In case of edit, I would like to evaluate it with value coming from database (e.g. news) to be selected.

谢谢.

推荐答案

模板HTML:

<select id="category-select">
    <option disabled="disabled" selected="selected">Please Select</option> 
    {{#each categories}}
        <option value="{{this}}">{{this}}</option>
    {{/each}}
</select>

模板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
    }
});
