[英]I am receiving an error from my JS code dealing with a sort function
所以我有這個用於類的代碼,但是每當我運行它時,瀏覽器中都沒有顯示任何內容,而是在控制台下,我收到一個錯誤,指出 data.sort 不是一個函數。
這是完整的代碼。
// Use d3 to read the JSON file.
// The data from the JSON file is arbitrarily named importedData as the argument.
d3.json("data/data.json").then((importedData) => {
// console.log(importedData);
var data = importedData;
// Sort the data array by using the greekSearchResults value.
data.sort(function(a, b) {
return parseFloat(b.greekSearchResults) - parseFloat(a.greekSearchResults);
});
// Slice the first 10 objects for plotting.
data = data.slice(0, 10);
// Reverse the array because of the Plotly defaults.
data = data.reverse();
// Trace1 for the Greek data.
var trace1 = {
x: data.map(row => row.greekSearchResults),
y: data.map(row => row.greekName),
text: data.map(row => row.greekName),
name: "Greek",
type: "bar",
orientation: "h"
};
// Data
var chartData = [trace1];
// Apply the group bar mode to the layout.
var layout = {
title: "Greek gods search results",
margin: {
l: 100,
r: 100,
t: 100,
b: 100
}
};
// Render the plot to the div tag with the id of "plot".
Plotly.newPlot("plot", chartData, layout);
});
sort
是一種數組方法。 我的猜測是 importData 變量不是數組,因此您會收到該錯誤。 如果您想使用它,請確保從數據響應創建一個數組。
