I am working on a project ASP.net 4, MVC4(RC) using visual studio 11. I am trying to render an MVC4 Razor view that renders a partial view. I have some javascript required for my partial view. On my partial view when I include my javascript inside the scripts section as follows it does not seem to load.
@section Scripts {
<script type="text/javascript">
$(function () {
alert("test");
});
</script>
}
If I remove the scripts section it fails as the jquery libraries (which are bundled and rendered on my _Layout.cshtml page) have not yet loaded when the document ready code runs.
<script type="text/javascript">
$(function () {
alert("test");
});
</script>
_Layout Page code to load jquery libraries
@Scripts.Render("~/bundles/jquery")
@RenderSection("scripts", required: false)
Does anyone know of a solution for this, or am I simply going about it the wrong way? Its wrecking my head!!
JavaScript functions can be bound to elements on the partial view; the partial view is rendered at the same time as the parent view. This happens when loading the partial view with a @Html. Action helper method, as in this section from Edit.
Rendering a Partial View You can render the partial view in the parent view using the HTML helper methods: @html. Partial() , @html. RenderPartial() , and @html. RenderAction() .
Bundling and minification are two techniques you can use in ASP.NET to improve page load performance for your web application. Bundling combines multiple files into a single file. Minification performs a variety of different code optimizations to scripts and CSS, which results in smaller payloads.
Partial views shouldn't be used to maintain common layout elements. Common layout elements should be specified in _Layout. cshtml files. Don't use a partial view where complex rendering logic or code execution is required to render the markup.
Don't wrap your script in a document.ready
in the partial:
@section Scripts {
<script type="text/javascript">
alert("test");
</script>
}
Ah, and don't put scripts in partials. Javascript code should be placed in separate javascript files. If you want to execute some javascript when a partial is loaded, you simply externalize this script into a reusable function/plugin that you call once your partial is loaded.
Finally got this to work. I removed my javascript from my partial view and placed it in the parent view (which is not partial), in the script section.This scripts section was created automatically when creating the view with scaffolding (Create) and was placed at the end of the page. To get this to work I had to move it to the top of the page - before the call to render my partial.
