A brief discussion on the application of json.stringify() and json.parse()

This article will briefly talk about json.stringify() and json.parse(), and see the application through code examples. It has certain reference value. Friends in need can refer to it. I hope it will be helpful to everyone.

JSON.stringify() converts a js object into a JSON string, and JSON.parse() can convert a JSON string into an object js object.

Application:

//判断数组是否包含某对象
function checkObjInArray(arr,obj){
　　//if(!arr) {
　　//　　arr = [ {name:'aaa'}, {name:'bbb'}, {name:'ccc'}, ];
　　//}
　　//if(!obj) {
　　//　　obj = {name:'ddd'};
　　//}
　　if(JSON.stringify(arr).indexOf(JSON.stringify(obj)) !== -1){
　　　　return true;
　　}else{
　　　　return false;
　　}

}

//判断两数组/对象是否相等
function checkObjEq(obj1,obj2){
　　if(JSON.stringify(obj1) === JSON.stringify(obj2)){
　　　　return true;
　　}else{
　　　　return false;
　　}
}
