Question

很简单：

<script id="write-tpl" type="text/x-handlebars-template">
    <canvas data-processing-sources="processing.pde"></canvas>
</script>

画布标签是否未正确转义或是什么？我也试过以下内容，但无济于事：

<canvas data-processing-sources="processing.pde"><{{!}}/canvas>

如何在我的handlebars.js模板中包含带有源的画布并将其渲染？

              constrain_width: false, // Does not change width of dropdown to that of the activator
              hover: false, // Activate on click
              alignment: 'left', // Aligns dropdown to left or right edge (works with constrain_width)
              gutter: 0, // Spacing from edge

  <script>
    var data = {

我的模板：

<script id="write-tpl" type="text/x-handlebars-template">

      <script id="write-tpl" type="text/x-handlebars-template">
        <canvas data-processing-sources="js/processing.pde" width="{{width}}" height="{{height}}" style="background:{{background}};"></canvas>
        <{{!}}/script>

    </script>

以下页面底部的脚本：

    <!-- Popup -->
    <script src="view.min.js?auto"></script> 

    <!-- Processing -->
    <script src="js/processing.js"></script>

Answer 1

删除模板中的内部脚本：

<script id="write-tpl" type="text/x-handlebars-template">
      <script id="write-tpl" type="text/x-handlebars-template">
         <canvas data-processing-sources="processing.pde" width="{{width}}" height="{{height}}" style="background:{{background}};"></canvas>
      <{{!}}/script>
</script>

像这样：

<script id="write-tpl" type="text/x-handlebars-template">
    <canvas data-processing-sources="processing.pde" width="{{width}}" height="{{height}}" style="background:{{background}};"></canvas>
</script>

这是一个有效的例子：

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="utf-8">
    <title>untitled</title>
    <script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
    <script type="text/javascript" src="http://builds.handlebarsjs.com.s3.amazonaws.com/handlebars.min-latest.js"></script>
    <script type="text/javascript" src="https://cdnjs.cloudflare.com/ajax/libs/processing.js/1.4.16/processing.min.js"></script>
</head>
<body>

    <script id="write-tpl" type="text/x-handlebars-template">
        <canvas data-processing-sources="processing.pde" width="{{width}}" height="{{height}}" style="background:{{background}};"></canvas>
    </script>


    <div id="content"></div>

    <script>
        $(document).ready(function(){
            var data = {
              width: 200,
              height: 100,
              background: "#000"
            };

            var template = Handlebars.compile($("#write-tpl").html());

            $("#content").html(template(data));

        });
    </script>


</body>
