Currently, I am in the process of developing a Typescript plugin that generates a DOM for Header and attaches it to the page. This particular project utilizes JQuery for handling DOM operations. To customize the plugin further, I aim to transmit config Options from the HTML page. To achieve this, I have extended JQuery with my own function and included the options within it.
However, upon loading the HTML page, I encounter an error: "$(...).createCentralHeader is not a function".
Below is a snippet of my Index.html file:
<!DOCTYPE html>
<html lang="en">
<body class="siteheader-body">
<div class="cep-Header"></div>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.12.4/jquery.min.js"></script>
<script src="./dist/cep_HeaderCore.js"></script>
<script>
$('cep-Header').createCentralHeader({
headerUrl: "Hello World!!"
});
</script>
</body>
</html>
This section outlines my main.ts file:
import * as $ from "jquery";
$.fn.createCentralHeader = function(this: JQuery, options?: HeaderOptions) {
const settings: HeaderOptions = {
headerUrl: options.headerUrl
};
alert(settings.headerUrl);
};
In addition, here is my central-header.d.ts :
interface HeaderOptions {
headerUrl?: string;
}
interface JQuery {
createCentralHeader(options?: HeaderOptions);
}
It's worth noting that my webpack configuration employs ts-loader to transpile TypeScript code and bundle the plugin into cep_HeaderCore.js, which is referenced in index.html.
Furthermore, when invoking createCentralHeader from within the plugin itself, it functions properly. For instance:
import * as $ from "jquery";
$.fn.createCentralHeader = function(this: JQuery, options?: HeaderOptions) {
const settings: HeaderOptions = {
headerUrl: options.headerUrl
};
alert(settings.headerUrl);
};
$("cep-Header").createCentralHeader({
headerUrl: "Hello World!!"
});
The question arises: What could possibly be going wrong in this scenario?
