preface

Most of the time, you need to convert a JSON string to a JSON object, and then process it in a loop, or convert a JSON object to a JSON string as a parameter and pass it to the relevant interface. Next, we will introduce several conversion methods

Assume that the JSON string is

Var jsonstr = ‘[{“Id”: 1, “title”: “Zhang San”, “sex”: “male”}, {“Id”: 2, “title”: “Li Si”, “sex”: “male”}]’;

Assume that the JSON object is

Var jsonobj = [
{
“Id”: 1,
“title”: “Zhang San”,
“sex”: “male”
},
{
“Id”: 2,
“title”: “Li Si”,
“sex”: “male”
}
]

var jsonObj = eval('(' + jsonStr + ')');

var jsonObj = JSON.parse(jsonStr);

var jsonObj = JSON.parse(jsonStr);

var jsonStr = JSON.stringify(jsonObj);

for (var i = 0; i < jsonObj.length; i++) {

    var name= jsonObj[i].Title;

}
