Question

I’m getting an unexpected identifier error with this line of code: var player[data[x].split("|",1)] = data[x].split("|")[1];

The response data is in this format:

Mike Trout|0\nRyan Braun|0\n...

Here is the full JS function:

function updateChance(round, pickNumber)
{
    $.ajax({
            type: "GET",
            data: {round: round, pickNumber: pickNumber},
            url: "./lib/updatechance.php",
            dataType: "html",
            async: false,
            success: function(response) 
            {
                var data = response.split("\n");
                for (var x=0; data.length; x++)
                {
                    var player[data[x].split("|",1)] = data[x].split("|")[1];
                }

                for (var r = 1; r < $('#battersTable').rows.length; r++){
                    //do something with player

                }
            }
    });
}

Look what you did here

.split("|",1)  //wrong

and

.split("|")[1]  //right

another issue, you have var with the bracket notation, not going to happen.

var player[data[x].split("|",1)]  <-- var, should not be there

And the for loop is missing a check so that is going to run infinite.

for (var x=0; data.length; x++)  <-- data.length what?

Why are you splitting twice? Twice the effort, do it once

for (var x=0; x<data.length; x++) {
    var info = data[x].split("|");
    player[info[0]] = info[1];
}

If player is not defined globally, you will need to define it before the loop.
