I want to update the existing json file in AngularJS
JSON file:
{
"text1": "Click here to edit!",
"text2": "Click here to edit!",
"text3": "Click here to edit!",
"text4": "Click here to edit!"
}
I want to update this JSON file as:
text1: "Abc"
and save this changes in JSON file
You can not update a json file without using a server-side language like PHP or python. Basically it is security compliance. For more understanding kindly go through https://docs.angularjs.org/guide/security https://docs.angularjs.org/api/ng/directive/ngCsp and https://developer.mozilla.org/en-US/docs/Web/Security/CSP
Imagine you have getjson.php and savejson.php in the server which work exactly as their names suggest.
Now use $http service of Angular to retrieve your json from the server.
$http.get("getjson.php").then(function(response){
$scope.myJsonObject = response.data;
//Your json becomes JS object here. Change it the way you want
$scope.myJsonObject.text1 = "Abc";
});
Use $http service again to send your json back to the server.
$http({
method: "post",
url: "savejson.php",
data: $scope.myJsonObject,
headers: { 'Content-Type': 'application/json; charset=utf-8' }
});
This is the basic. Please note that you need to do your php part to save/load your json file. Also you should handle errors of the $http service.
getjson.php and savejson.php deal with the same file.
