Socket.io数据为HTML文本

Question

I get data like this that is logged in the console from a socket.io url which is triggered on certain events. Now all I would like to do is get specific data from that, like the amount.

I've tried so many things to just get the amount value and anything else, but nothing seems to work.

Here's the only code I'm using in my .php file.

 <script src='https://cdnjs.cloudflare.com/ajax/libs/socket.io/2.0.3/socket.io.js' type='text/javascript'></script> <script> const socketToken = 'mytokenishere'; //Socket token from /socket/token end point //Connect to socket const streamlabs = io(`https://sockets.streamlabs.com?token=${socketToken}`); //Perform Action on event streamlabs.on('event', (eventData) => { if (!eventData.for || eventData.for === 'streamlabs' && eventData.type === 'donation') { //code to handle donation events console.log(eventData.message); } if (eventData.for === 'twitch_account') { switch(eventData.type) { case 'follow': console.log(eventData.message); break; case 'subscription': //code to handle subscription events console.log(eventData.message); break; default: //default case console.log(eventData.message); } } }); </script> 

I've tried doing things as document.write(eventData.message); but that returns [object Object]
I also tried document.write(["0"].amount); that returns undefined

I really appreciate all replies, thank you in advance if you know any solution!

EDIT: document.write(JSON.stringify(eventData.message)); gives me

[{
    "isTest":true,
    "formatted_amount":"$87.00",
    "amount":87,
    "message":"This is a test donation for $87.00.",
    "currency":"USD",
    "from":"John",
    "from_user_id":1,
    "_id":"c3135e2c8011e545091f020f8378***"
}] 

It looks like it's an object within an array, I need to figure out how to make it so it's only an object.

document.write(eventData.message[0].from); document.write(eventData.message[0].formatted_amount);
results: John $87.00

So it was very simple.. Thank you!

Answer 1

eventData.message[0] should give you the base object you are looking for.

you have an array of objects being sent so you need to extract the first element of that array by accessing the index 0.

for instance eventData.message[0].amount should be 48

Edit: I saw your edit where you state

It looks like it's an object within an array, I need to figure out how to make it so it's only an object.

Just create a new object to alias the name when you get it.

var data = eventData.message[0];
console.log(data.amount);

Answer 2

It's simple to access to array items by index number. For example:

console.log(eventData.message[0]) // log first item of eventdata's message
