DataviewJS - How to use .Where to compare metadata's link field( field :: [[TypeName]]) ?

[Another5405]

I want to use some field to define file Type like NoteType:: [[Data]] or Type:: [[Task]]
that will also inculde field to link collection like MOC::[[MOC Sleep]] or Project:: [[Some Project]]

and I don't know how to compare these field.

these way I was tried:

dv.pages("[[Some Project]]").where( t =>

     t.Type == "[[Task]]"
     t.Type == dv.page("Task");
     dv.equal(t.Type, dv.page("Task")))
)

Sadly,they were not working.
(Also, t.Type[0] or t.Type.file return ERROR)

I'm sure Task file is the same file.
And I can list the Type using dv.list(dv.pages("[[Some Project]]").Type)) to list array of each file Type.

Request experiencer save my day,
Thanks in advance.

What's the overall use case/query that you're trying to do?

As for an actual answer, wikilinks are actually Link objects in DV, like the one in .file.link. You can compare those via dv.equal. "[[stuff]]" is just a string which is why comparisons fail.

ThankYou so much, I get it now.

//Button
const {update} = this.app.plugins.plugins["metaedit"].api;
const buttonMaker = (pn, pv, fpath) => {
    const btn = this.container.createEl('button', {"text": "Done!"});
    const file = this.app.vault.getAbstractFileByPath(fpath)
    btn.addEventListener('click', async (evt) => {
        evt.preventDefault();
        await update(pn, pv, file);
    });
    return btn;
}

let TypeFile = dv.page("Task");
//dv.el("b",TypeFile.file.link)

dv.table(["Name", "MissionState", "Button"], dv.pages("[["+ProjectFile.file.name+"]]")
    .sort(t => t["MissionState"], 'desc')
    .where(t =>  t.MissionState !="Done" && dv.equal(t.Type, TypeFile.file.link))
    .map(t => [t.file.link, t.MissionState, buttonMaker('MissionState', 'Done', t.file.path)])
    )

That works , And

let ProjectFile = dv.page(app.workspace.getActiveFile().path);
dv.el("b",dv.pages("[["+ProjectFile.file.name+"]]")[0].Type.type)

these Type will be return "file" make me confuse by day,
so I have not think about dv.equal(t.Type, TypeFile.file.link))
