When I print the created_at field of a model using Backbone.js( <i> {{created_at}} </i>
), I m getting: 2011-08-07T12:03:00Z
.
I m试图将日期改为可读格式,而Im无法阅读。
我希望在印刷前删除T和Z。
感谢

改变贵模板中的变量,或增加新的变量。 我要补充一个新的内容。
如果你行使这一职能,可以改为:
render: function() {
var context = this.model.toJSON();
context[ created_at_formatted ] = this.formatDate(context[ created_at ]);
var html = this.template.to_html(context);
$(this.el).html(html);
}
加上以下观点:
formatDate: function(d) {
var pad = function (n) {
return n < 10 ? 0 + n : n;
};
// in case the date is a string; you can remove this if you know it will be a date
if (typeof date === string ) {
d = new Date(d);
}
return [
d.getUTCFullYear(), - ,
pad(d.getUTCMonth() + 1), - ,
pad(d.getUTCDate()), ,
pad(d.getUTCHours()), : ,
pad(d.getUTCMinutes()), : ,
pad(d.getUTCSeconds())
].join("");
}
Then the template would be like this:
<i> {{created_at_formatted}} </i>
为了简化日期格式功能,你还可以使用日期格式图书馆,如。 你还可以将日期格式移至模式。
Readable? Why not jQuery timeago? jQuery timeago
阁下,
toTemplateData: ->
_.extend
created_duration: do => $.timeago @get("created_at") if @get("created_at")
阁下,
render: ->
@$el.html(@template(@model.toTemplateData() ))
在您的模板中,
<time title="{{created_duration}}"></time>
You can use the strftime on your created_at
<i> {{created_at.strftime( %Y/%m/%d )}} </i>
本答复是正确的,但该日期的编排格式实际上应当是一个模式,因为它是业务逻辑。
我的改动是:
render: function() {
var context = this.model.format().toJSON();
var html = this.template.to_html(context);
$(this.el).html(html);
}
以及你的模式,例如:
format() {
this.set( created_at_formatted , formatDate(this.get( created_at )));
return this;
}
formatDate: function(d) {
// format date stuff (See Ben`s answer)
return d;
}
And your template would render:
<i> {{created_at}} </i>
这消除了某些 red余,促进了再利用,更容易阅读。 也许我的答案需要一点工作,但希望大家能了解这个总的想法。
