• 如何从当天获得天差异.

• tweetedAt:"2015-02-22 09:56:42".

枝条

{% for key,value in data.about %}
{% set tweets_date=(value.tweetedAt|date).date("now").format('%a') %}
{% endfor %}

我也试过了

{% set dd='now'|date('d-m-Y') %}
{% set tweets_date=(value.tweetedAt|date).dd.format('%a') %}

最后我试了但是给出了错误:

散列键必须是带引号的字符串,数字,名称或括在括号中的表达式(值为"{"的意外标记"标点符号")

{% set difference = {{ date("m/d/Y") }}.diff(date(value.tweetedAt)) %}
{% set leftDays = difference.days %}

错误:

<span class="small light_grey">{{tweets_date}}</span>

Impossible to invoke a method ("date") on a string variable ("June 6, 2015 01:06") in AcmeBundle

twig/extensions通过composer 更新了我的项目安装

我想在bootstrap模式中追加html代码

HTML内容:

<div class="modal fade" id="share12" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true">
   <div class="modal-dialog">
      <div class="modal-content get_direction_modal_bg">
         <div class="text-right"><a class="fa fa-times white normal12" data-dismiss="modal"> close</a></div>
         <div class="modal-body">
            <p class="white text-center">Share this Event</p>
            <div class="share_list_popup">
               <ul>

           <li><a href="https://www.facebook.com/sharer/sharer.php?u=www.10times.com&title=Come join me at"+eventname+"on "+eventstartdate+", "+eventcityname+""></a></li>
                  <li><a href="http://www.linkedin.com/shareArticle?mini=true&utm_campaign=201308&url=http://10times.com/"+eventname+"&title=Come join me at  "+eventname+" on "+eventstartdate+","+eventcityname+".&utm_source=LinkedIn&source=LinkedIn
                     Come join me at "+eventname+" on "+eventstartdate+","+eventcityname+". Find event details at 10times.com/"+eventname+""></a>
                  </li>


               </ul>
            </div>
         </div>
      </div>
   </div>
</div> 
<a href="#" data-target="#share12" data-toggle="modal"><img src="images/share.png"></a>

Javascript代码:

 var modal_event_name=document.getElementById("modal_event_name");
 var modal_event_startdate=document.getElementById("modal_event_name");
 var modal_city_name=document.getElementById("modal_event_name");
 $('#share12').modal('show'); …

使用案例:

1. 当src不为null且alt标记不为null时,则显示src的图像.
2. 然后检查src图像网址不是404.
3. 当src为null且alt不为null时,显示名字的图像.
4. 当src和alt为null时,显示默认图像

HTML:

<img class="imagelazy" id="lazyimage" src="http://url" alt="ankit">

使用Javascript:

function imagelazy() {

    $(document).ready(function()

        {
            var image = $(".imagelazy").attr('src');
            var altdata = $(".imagelazy").attr('alt');
            var alt = $(".imagelazy").attr('alt').split("");
            //var imagepath="http://im.gifbt.com/userimages/"+alt[0].toLowerCase()+".jpg";
            var defaultimage = "http://im.gifbt.com/img/no-pic.jpg";
            console.log(image);
            console.log(alt);
            $(".imagelazy img")
                .error(function() {
                    $(this).hide();
                })
                .attr("src", defaultimage);

            if (image != '' && altdata != '') {
                console.log("afeef");
                $('.imagelazy').bind('error', function() {
                    $(this).attr("src", defaultimage);
                });
                $(".imagelazy img")
                    .error(function() {
                        $(this).hide();
                    })
                    .attr("src", defaultimage);
