是否可以设置圆点样式text-overflow: ellipsis？

一个例子是像'Lorem Ips ...... ' 那样用省略号加粗.

基本上我想弄清楚的是如何检索一个跨度(id ="camera_status")的值,该值已经使用phonegap捕获后用图像名称填充.

我希望它的工作方式是将图像名称与提交的表单信息一起上传到数据库.目前,在使用图像名称填充范围之前,它似乎正在读取初始空白值.如果有人知道我如何解决这个问题,我将不胜感激.

表单页面的HTML和Javascript

<div>
  <input type="button" onclick="takePicture();" value="Take Picture" /><br/>
</div>
<div>
<div>
    <b>Status:</b> <span id="camera_status"></span><br>
    <b>Image:</b> <img style="width:240px;visibility:hidden;display:none;" id="camera_image" src="" />
</div>      
<div id="landmark-1" data-landmark-id="1">
<form id="uploadForm">
    <label for="email">
        <b>Email</b>
        <input type="email" id="email" name="email">
    </label>

    <label for="comment">
        <b>Comment</b></br>
        <input id="comment" name="comment" cols="30" rows="10"></textarea>
    </label>
    <input type="button" onclick="uploadPicture();" value="Upload New location" />  
    <input type="submit" value="Upload New location" />

    </form>

<script>
var spanValue = $('#camera_status').html()

$(function(){

$('#uploadForm').submit(function(){
    var landmarkID = $(this).parent().attr('data-landmark-id');
    var postData = $(this).serialize();

    $.ajax({
        type: 'POST',
        data: postData+'&lid='+spanValue, …

我有两个函数可以用来获取过去7天的日期并将其格式化为特定的格式,但它很慢,有没有人知道更好的方法可能使用循环或类似的东西？

 function formatDate(date){

    var dd = date.getDate();
    var mm = date.getMonth()+1;
    var yyyy = date.getFullYear();
    if(dd<10) {dd='0'+dd}
    if(mm<10) {mm='0'+mm}
    date = mm+'/'+dd+'/'+yyyy;
    return date
 }

 function Last7Days () {

      var today = new Date();
      var oneDayAgo = new Date(today);
      var twoDaysAgo = new Date(today);
      var threeDaysAgo = new Date(today);
      var fourDaysAgo = new Date(today);
      var fiveDaysAgo = new Date(today);
      var sixDaysAgo = new Date(today);

      oneDayAgo.setDate(today.getDate() - 1);
      twoDaysAgo.setDate(today.getDate() - 2);
      threeDaysAgo.setDate(today.getDate() - 3);
      fourDaysAgo.setDate(today.getDate() - 4);
      fiveDaysAgo.setDate(today.getDate() - 5);
      sixDaysAgo.setDate(today.getDate() …
