What is the reason for encountering the error message "Property 'floatThead' does not exist on type 'JQuery<any>' when trying to use floatThead in Angular/TypeScript?

Question

What is the reason for encountering the error message "Property 'floatThead' does not exist on type 'JQuery<any>' when trying to use floatThead in Angular/TypeScript?

For my project, I am incorporating the third-party jQuery library called https://github.com/mkoryak/floatThead.

To work with Bootstrap and jQuery, I have installed them using NPM through the command line. Additionally, I have used NPM to install floatThead.

Within my component, I have imported these modules:

import * as $ from 'jquery';
import 'floatThead';

I have successfully selected the table element in this manner:

<table class="table table-responsive table-bordered table-hover" #tableElement>

@ViewChild('tableElement')
private tableElement: ElementRef;

Despite attempting to call floatThead() like so, I encounter an error and do not see any changes reflected on my site:

public ngAfterViewInit(): void {
   $(this.tableElement.nativeElement).floatThead({top: 50});
}

If anyone can provide insight into why this might be happening, it would be greatly appreciated.

Answer №1

If you're using floatThead, make sure to upgrade to the latest version that includes TypeScript types for smoother integration.

For more information, check out the TypeScript types at: https://github.com/mkoryak/floatThead/blob/master/dist/jquery.floatThead.d.ts

Here is a snippet of what the TypeScript types look like:

interface floatTheadOptions {
    position?: string;
    scrollContainer?: ($table: JQuery) => JQuery;
    responsiveContainer?: ($table: JQuery) => JQuery;
    ariaLabel: ($table: JQuery, $headerCell: JQuery, columnIndex: number) => string;
    headerCellSelector?: string;
    floatTableClass?: string;
    floatContainerClass?: string;
    top?: number;
    bottom?: number;
    zIndex?: number;
    debug?: boolean;
    getSizingRow?: ($table: JQuery, $cols: JQuery, $fthCells: JQuery) => JQuery;
    copyTableClass?: boolean;
    autoReflow?: boolean;
}

interface JQuery {
    floatThead(floatTheadOptions?: floatTheadOptions): JQuery;
    floatThead(action: string): JQuery;
    trigger(action: string): JQuery;
    on(events: string, handler: (event: Event, $floatContainer: JQuery) => void|boolean): JQuery;
    on(events: string, handler: (event: Event, isFloated: boolean, $floatContainer: JQuery) => void|boolean): JQuery;
}

You could consider incorporating

import * as floatThead from 'floatthead';

If feasible, it would be great to see an example of this code on stackblitz

The reason why TS doesn't recognize floathead is because there are no specific types defined for it, so even if the script is included, TypeScript won't know about the $(xxx).floathead() invocation.

To resolve this issue, you can include both jquery and floathead in the scripts section of your angular.json file. After that, you have two options:

Option 1: Add the following line below your Angular imports:

declare let $: any;

Option 2: If you have already installed jquery types (@types/jquery), you can extend the JQuery interface like this:

interface JQuery
{
      floathead(options: any): JQuery;
}

Then, at the top of your component file, add:

declare let $: JQuery;
