JQPlot不被jQuery识别

Question

我正在开发一个Web应用程序,我非常喜欢JQPlot提供的拖动图.我在他们的网站上提到了这个例子:http: //www.jqplot.com/deploy/dist/examples/customHighlighterCursorTrendline.html

据我所知,为了让JQPlot正常工作,我需要包含jQuery,jQuery jqplot函数和一些样式文件.JQPlot下载提供了自己的jquery.js和jquery.jqplot.js.

另外,我也使用Knockout.js作为这个项目的一部分,我将包含标准的jquery-1.9.1.js文件以使其正常工作.

但是,"$"的定义文件是jquery-1.9.1.js,并且由于JQPlot提供了自己的jQuery文件,因此必然存在某种冲突,使jqplot函数无法识别.这有解决方法吗？这是我的HTML代码:

@model FluidBedSimulation.Models.BedState
@using Newtonsoft.Json

@{
    ViewBag.Title = "Index";
}

            @Html.TextBoxFor(model => model.binderFraction, new { data_bind = "value: binderFraction" })
</p>

<button data-bind="click: Simulate">Simulate</button>


@*to be used later as controls for the simulation*@
<div id="chartdiv" style="height:400px;width:300px; "></div>

<script type="text/javascript">

    this.BedMass = ko.observable(1);
    this.BedWaterMass = ko.observable(1);
    this.binderFraction = ko.observable(1);

    (function () {
        var model = '@Html.Raw(Json.Encode(Model))';
        var viewModel = ko.mapping.fromJS(model);
        ko.applyBindings(viewModel);

    })();

</script>

我在运行项目时得到的确切错误是:"Uncaught TypeError:无法读取未定义的属性'config'"这是触发它的行: $.jqplot.config.enablePlugins = true; 当我写"$"时.在Visual Studio中,jqplot甚至不是一个选项.我搜索了一堆线程,但似乎找不到任何相关的东西.我想知道是否有一些方法可以同时使用jqplot和knockout(以及其他使用标准jquery文件的东西).提前致谢!

我有同样的问题.我追踪了jquery.jqplot.js文件的处理并且它正在被执行,配置已经定义,并且在文件处理结束时,一切似乎都存在(即变量被正确分配给jQuery变量和$别名).但是,当我到达$(document).ready()回调时,似乎$.jqplot未定义......

我发现扩展名'noty'也出现了同样的问题......最后我注意到在我的Layout.cshtml末尾(我在MVC 4中实现)我发现有一个@RenderSection("scripts", required: false)在之前引用了JQuery包.

总结:jQuery包被包含在HTML的head部分(由我)中,然后再次包含在页脚中(它覆盖了html中包含的所有扩展<head>).这是MVC 4模板的一个特性 - 我并不喜欢这个模板.
