I want to use the jQuery UI datepicker with Angular 5, but it doesn't work...
First I wrote a simple html file without Angular:
<html lang="en">
<head>
<meta charset="utf-8">
<title>datepicker demo</title>
<link rel="stylesheet" href="../node_modules/jquery-ui/themes/base/all.css">
<script src="../node_modules/jquery/dist/jquery.min.js"></script>
<script src="../node_modules/jquery-ui/ui/widgets/datepicker.js"></script>
</head>
<body>
<div id="datepicker"></div>
<script>
$( "#datepicker" ).datepicker();
</script>
</body>
</html>This works great! When I open the file in a browser, the datepicker is inserted in the div. Now i want to use the datepicker inside of an angular component. Here are my files:
define-filter-component.component.ts:
import { Component, OnInit } from '@angular/core';
import * as $ from 'jquery';
import 'jquery-ui';
@Component({
selector: 'app-define-filter-component',
templateUrl: './define-filter-component.component.html',
styleUrls: ['./define-filter-component.component.css']
})
export class DefineFilterComponentComponent implements OnInit {
constructor() { }
ngOnInit() {
$('#datepickerdiv').html('Hi there!'); // This is working!
$('#datepickerdiv').datepicker(); // Browser says "TypeError: $(...).datepicker is not a function"
}
}define-filter-component.component.html:
<p>
define-filter-component works!
</p>
<div id="datepickerdiv">XXX</div>The scripts and styles in angular-cli.json:
"styles": [
"../node_modules/semantic-ui-css/semantic.css",
"../node_modules/jquery-ui/themes/base/all.css"
],
"scripts": [
"../node_modules/jquery/dist/jquery.min.js",
"../node_modules/jquery-ui/ui/widgets/datepicker.js"
],typings.d.ts (I added the reference tags):
/// <reference path="../node_modules/@types/jquery/index.d.ts" />
/// <reference path="../node_modules/@types/jqueryui/index.d.ts" />

}When running ng serve, I got this error message:
ERROR in ./node_modules/css-loader?{"sourceMap":false,"import":false}!./node_mod
ules/postcss-loader/lib?{"ident":"postcss","sourceMap":false}!./node_modules/jqu
ery-ui/themes/base/all.css
Module build failed: Error: Can't resolve 'base.css' in 'C:\Users\lotzevol\Deskt
op\TraceDetective\node_modules\jquery-ui\themes\base'
at onError (C:\Users\lotzevol\Desktop\TraceDetective\node_modules\enhanced-r
esolve\lib\Resolver.js:61:15)
Why "Can't resolve base.css"? The file does exist. Really!
I just removed the file .../all.css from angular-cli.json. The datepicker should also work without the CSS, even if it is not looking good.
Now the Compiler says: 'webpack: Compiled successfully'. Great!
I opened the Browser, but the datepicker doesn't appear! The Browser console says: TypeError: $(...).datepicker is not a function. What did I do wrong? It seems Angular doesn't like me...
I think there is something wrong with my import statements in define-filter-component.component.ts. Can anyone help please?
