Angular 6: saving data to local storage
you can use localStorage for storing the json data:
the example is given below:-
let JSONDatas = [
{"id": "Open"},
{"id": "OpenNew", "label": "Open New"},
{"id": "ZoomIn", "label": "Zoom In"},
{"id": "ZoomOut", "label": "Zoom Out"},
{"id": "Find", "label": "Find..."},
{"id": "FindAgain", "label": "Find Again"},
{"id": "Copy"},
{"id": "CopyAgain", "label": "Copy Again"},
{"id": "CopySVG", "label": "Copy SVG"},
{"id": "ViewSVG", "label": "View SVG"}
]
localStorage.setItem("datas", JSON.stringify(JSONDatas));
let data = JSON.parse(localStorage.getItem("datas"));
console.log(data);
You should define a key name while storing data to local storage which should be a string and value should be a string
localStorage.setItem('dataSource', this.dataSource.length);
and to print, you should use getItem
console.log(localStorage.getItem('dataSource'));
