Edit2:错误在这一行:<input type="button" value="totalbandwidthresult" onclick="javascript:totalbandwidth();">
试图让按钮执行计算.下面是必需的变量,以及HTML所在的位置
我收到错误点击: Uncaught TypeError: object is not a function index.html:71
onclick
这是我的Javascript
function totalbandwidth() {
var fps=Number(document.calculator.fps.value);
var bitrate=Number(document.calculator.bitrate.value);
var numberofcameras = Number(document.calculator.numberofcameras.value);
var encoding = document.calculator.encoding.value;
if (encoding = "mjpeg")
{
storage = bitrate*fps;
}
else
{
storage = bitrate;
}
totalbandwidth = (numberofcameras * storage) / 1000;
document.calculator.totalbandwidthresult.value = totalbandwidth;
}

另一种方法是使用检查点.我认为它们是使用提供的存储帐户凭据通过服务器(eventhub)保留的.它是否正确?
这是我目前使用的一些初步代码:
public class SimpleEventProcessor : IEventProcessor

private Stopwatch _checkpointStopWatch;
async Task IEventProcessor.CloseAsync(PartitionContext context, CloseReason reason)

必要脚本的链接在我的标题中:

EDIT/ADDENDUM:将ImagesLoaded和Masonry的脚本标签放在我需要的页面的实际.php文件中,而不是在header.php中,而是来自ImagesLoaded:来自ImagesLoaded:Uncaught TypeError:undefined不是函数
不确定为什么只是从标题下方移动标签会改变这一点,但至少现在我得到了imagesLoaded?
我需要一个图片上传指令,这是我的代码的样子:
# Model
class transporter(models.Model):
company_name = models.CharField(max_length=100)
address = models.CharField(max_length=100)
image = models.FileField(upload_to=upload_path,blank=True, null=True)

它只适用于django休息框架,但如果我使用angularjs发布传输器模型,我会收到错误的请求错误.我需要上传图片并使用图片网址设置图片字段.谢谢
