Question

我有一些来自本教程的Raphael-js代码：http://net.tutsplus.com/tutorials/javascript-ajax/an-introduction-to-the-raphael-js-library/，我正在尝试将工作代码包含在MVC3 Razor视图中。 javascript没有被执行。我似乎无法找到错误或良好的resorce解释如何在Razor中包含JavaScript。这是我的.cshtml，我希望Rapheael绘图在canvas_container div中呈现。

@{
    ViewBag.Title = "Home Page";
}
<h2>@ViewBag.Message</h2>

<div id="canvas_container">
</div>

@section JavaScript
{
    <script type="text/javascript" src="@Url.Content("~/Scripts/raphael.js")" />
    <script type="text/javascript">
        window.onload = function () {
            var paper = new Raphael(document.getElementById('canvas_container'), 500, 500);
            var circle = paper.circle(100, 100, 80);
            for (var i = 0; i < 5; i += 1) {
                var multiplier = i * 5;
                paper.circle(250 + (2 * multiplier), 100 + multiplier, 50 - multiplier)
            }
            var rectangle = paper.rect(200, 200, 250, 100);
            var ellipse = paper.ellipse(200, 400, 100, 50);
        }
    </script>
}

以下是未执行javascript的渲染视图：

                var circle = paper.circle(100, 100, 80);
                for (var i = 0; i < 5; i += 1) {
                    var multiplier = i * 5;
                    paper.circle(250 + (2 * multiplier), 100 + multiplier, 50 - multiplier)
                }
                var rectangle = paper.rect(200, 200, 250, 100);
                var ellipse = paper.ellipse(200, 400, 100, 50);

Answer 1

它无效，因为您的javascript遵循自我关闭的script标记，即invalid。

您需要更改

<script type="text/javascript" src="/Scripts/raphael.js" />

到

<script type="text/javascript" src="/Scripts/raphael.js"></script>

为什么我的javascript没有在这个Razor代码中执行？
