When utilizing TypeScript's tsc compiler, errors may be generated upon invoking jQuery and Flot code

When I run "make" on x86-64 Linux with this code (a branch of a GitHub repository), I encounter the following errors:


        shlomif@telaviv1:~/Download/unpack/to-del/TypeScript-flot$ make
        tsc --outFile foo.js foo.ts
        foo.ts(18,12): error TS2345: Argument of type 'string' is not assignable to parameter of type 'JQuery'.
        foo.ts(47,39): error TS2345: Argument of type '(event: JQueryEventObject, pos: any, item: any) => void' is not assignable to parameter of type 'boolean'.
        foo.ts(68,39): error TS2345: Argument of type '(event: JQueryEventObject, pos: any, item: any) => void' is not assignable to parameter of type 'boolean'.
        foo.ts(71,5): error TS2304: Cannot find name 'plot'.
        foo.ts(74,40): error TS2339: Property 'version' does not exist on type '{ (placeholder: JQuery, data: dataSeries[], options?: plotOptions): plot; (placeholder: JQuery, d...'.
        Makefile:6: recipe for target 'foo.js' failed
        make: *** [foo.js] Error 2
    

The relevant TypeScript code snippet is as follows:


        $.plot("#placeholder", [
            { data: series[0], label: "old-time(iters)", },
            { data: series[1], label: "new-time(iters)", },
        ],
        {
            series: {
                lines: {
                    show: true
                },
                points: {
                    show: true
                }
            },
            grid: {
                hoverable: true,
                clickable: true
            },
        }
    );
    

I am using the TypeScript tsc compiler along with jQuery definitions from https://github.com/DefinitelyTyped/DefinitelyTyped and a modified version of the jQuery Flot definitions to address other errors reported by the tsc compiler.

How can these errors be rectified?

Answer №1

An issue arises that indicates the inability to assign a string data type to a jQuery data type at line 18:

$.plot("#placeholder", [

To resolve this, we can convert line 18 into a jQuery object like so:

$.plot($("#placeholder"), [
