问题
I have been trying to make this owl carousel work. I am not getting any error but the carousel if not loading. I tried the solution I found on StackOverflow for Bootstrap carousel but it did not work for me. I also tried to use pure CSS carousel but it will be static kind of thing and I want the carousel to work dynamically.
Index.razor
@page "/"
@using TBS.Data;
@inject IJSRuntime JsRuntime;
@*@inject IComponentContext context;*@
@inject NavigationManager UriHelper;
@inject MediaService MediaService;
@inject ContentService ContentService;
<div class="container hero-section">
<div class="owl-carousel owl-theme slide">
<div class="hero-image item">
<img src="images/here-image.png" alt="hero-img" class="img-fluid">
<div class="hero-details">
<h2>MATT RISINGER</h2>
<h6>Home Builder. Austin, TX.</h6>
<a href="#"><button>EXPLORE CHANNEL</button></a>

回答1:
I had a similar issue, i figured it out that to use JavaScript library you need to use JInterop. So after referencing all required library, i created a js file in my root folder wwwroot called main.js, and i added the reference to my index.html file like this
<script src="main.js"></script>
Inside this main.js file i created a function that contains all the javascript code i need to run my slider. So the code inside main.js file looks like this.
(function($) {
'use strict';
window.sliderFunctions = {
startSlider: function () {
/*============ All the code or function you need for your slider to run goes here ============*/
--code--
}
}}
Then i opened my app.razor file, then injected JSRuntime like so
@inject IJSRuntime JSRuntime
then still in my app.razor file, i added the following code
@code {
protected async override Task OnAfterRenderAsync(bool firstRender)
{
await JSRuntime.InvokeAsync<string>("sliderFunctions.startSlider", null);
//return base.OnAfterRenderAsync(firstRender);
}}
What simple happened is, this allows to run all javascript code after Blazor is done rendering.
