Webcam.js 错误：找不到要附加到的 DOM 元素

Question

I am trying to use Webcam.js to capture image in my MVC project. But at the initial level I have an issue "Could not locate DOM element to attach to."

I have attached script

<style>
    .Camera {
        width: 320px;
        height: 240px;
        border: 1px solid black;
    }
</style>
<script type="text/javascript" src="~/Scripts/webcam.min.js"></script>
<script language="JavaScript">
    Webcam.set({
        width: 320,
        height: 240,
        image_format: 'jpeg',
        jpeg_quality: 90
    });
     Webcam.attach('#Camera');
</script>

In View

 <div>
       <div id="Camera" class="Camera"> </div>
    <br>
    <input type="button" id="takeshot" value="Capture" onClick="take_snapshot()" />
 </div>

What is the possible cause?

Answer 1

place your javascript functions beneath the tag/element id:camera and id:takeshot

Answer 2

Try this: Delete the class Camera, happened with me but after deleting the class and just keeping the "id" it worked.

camera = document.getElementById("camera");

Webcam.attach(camera);

Webcam.set({ width:350, height:300, image_format: 'png', png_quality:90 });
