ich weiß nicht, was ich falsch gemacht haben

Answer 1

Sie verwendet, um die ternären o Perator den falschen Weg. Sie können es wie folgt verwenden:

var data = localStorage.getItem("data") ? JSON.parse(localStorage.getItem("data")) : {}; 

Oder halten Sie die || Muster ohne ternären Operator:

var data = JSON.parse(localStorage.getItem("data")) || {}; 

Dies wird null weil JSON.parse(null) kehrt arbeiten.
