I am trying to toggle between a table and a graph. I have written a couple of functions save the state that the user switches to using localstorage. But when I console.log localStorage.getItem, i see the value as null. What am I missing? const data = document.querySelectorAll("button.data"); const dataTable = document.querySelector(".dataTable"); const dataGraph = document.querySelector(".dataGraph"); const ViewdataGraph = () => { dataTable.style.display = "none"; dataGraph.style.display = "block"; data.forEach( (element) => (element.innerText = "View data Table")); localStorage.setItem("dataViewType", "Graph"); } const ViewdataTable = () => { dataGraph.style.display = "none"; dataTable.style.display = "block"; data.forEach( (element) => (element.innerText = "View data Graph")); localStorage..setItem("dataViewType", "table"); } const Toggledata = () => { const dataType = localStorage.getItem("dataViewType"); if (dataType) { if (dataType === "table") { ViewdataTable(); } else if (dataType === "Graph") { ViewdataGraph(); } } }; window.addEventListener("DOMContentLoaded", (event) => { const data = document.querySelectorAll("button.data"); data.forEach((element) => element.addEventListener("click", (event) => ToggleData()), ); }
