I receive socket data, but the bound server keeps sending data. why do I receive only one string?

I receive socket data, but the data on the bound server is sent all the time. why do I receive only one string of sent data? @, $, this is what I receive.
{"Is_ OK": 1, "data": @, $}
However, the data is always sent, although it is all the same string of data, but I only accept a string, there will be no later. how to define the start and end signs of the data !! I want to add it to the database on the server, but how can I convert it to the json data format! How can I change the data sending format? because ajax is used to add data to highchart. how can I call this data string! Is it a json Array!

You only get data once.

Which of the following statements can I ask the moderator how to write multiple requests and time intervals? you don't need to define the start and end mark of the string of data! Thank you moderator

You only get data once.

If you want to add the string of data to the database, how can you modify the format (original format or received) and call the string data,

After you call the client program multiple times, you can receive the data multiple times.
How to put data into the database depends on how your database is saved.
The format of transmitted data should be designed according to your needs.

Function connect () {$. ajax ({url: 'client. php? Msg = web', type: 'GET', Ype: 'json', success: function (result) {// the data returned by the server and processed according to the dataType parameter; A string that describes the status. $ ('# Tb tr: gt (0 )'). remove (); // delete the previous data if (result. is_ OK) {var x = (new Date ()). getTime (); $. each (result. data, function (I) {var index = parseInt (result. data [I]. point)-1; chart01.series [index]. addPoint ([x, parseFloat (result. data [I])], true, true); chart02.series [index]. addPoint ([x, parseFloat (result. data [I])], true, true); chart03.series [index]. addPoint ([x, parseFloat (result. data [I])], true, true); chart04.

How to assign the obtained data to each chart table, {"is_ OK": 1, "data": [,]}, how to display data in series. I hope to give some practical suggestions. Thank you.

We recommend that you carefully read the Highcharts ajax examples.
Definitely more professional than me

I don't know how to take out the data value, such as result. data [I ].

One request by your code is of course a result.

One request by your code is of course a result.

I open the website only once! Requests are continuously sent only when refresh is not stopped. So I added this
$. Each (result. data, function (I ){
Var index = parseInt (result. data [I]. point)-1;

Chart01.series [index]. addPoint ([x, parseFloat (result. data [I])], true, true );
Chart02.series [index]. addPoint ([x, parseFloat (result. data [I])], true, true );
Chart03.series [index]. addPoint ([x, parseFloat (result. data [I])], true, true );
Chart04.series [index]. addPoint ([x, parseFloat (result. data [I])], true, true );
Chart05.series [index]. addPoint ([x, parseFloat (result. data [I])], true, true );
Chart06.series [index]. addPoint ([x, parseFloat (result. data [I])], true, true );
Chart07.series [index]. addPoint ([x, parseFloat (result. data [I])], true, true );
Chart08.series [index]. addPoint ([x, parseFloat (result. data [I])], true, true );
Chart09.series [index]. addPoint ([x, parseFloat (result. data [I])], true, true );
Chart10.series [index]. addPoint ([x, parseFloat (result. data [I])], true, true );
}, 1000); // The data is automatically retrieved at intervals of 1000.
The key is how to give the data value to the coordinate chart1.series [index]. addPoint ([x, parseFloat (result. data [I])], true, true );
