在表格中打印數組？ Javascript / HTML
[英]Printing array in a table? Javascript / HTML
問題描述
在這個項目中，我必須寫日記，其中一個標准是一張表格，該表格記錄了之前輸入的約會數量。 目前這是我的腳本，但它有效，當我有多個年份時，計數僅識別第一年，而不會識別第二年。 而是將其識別為 NaN。 有人可以幫忙並指出我哪里出錯了。 萬分感謝 ：）

將您的匯總功能更改為
function summary() {
var year;
var val = document.getElementById('tallyOption').value
if (val == 'year') {
thead1.innerHTML = ("<td>" + 'Year' + "</td>" + "<td>" + 'Appointments' + "</td>");
for (i = 0; i < dates.length; i++) {
const date = new Date(dates[i])
const year = date.getFullYear()
if (!yearSum[year]) {
yearSum[year] = 1
} else {
yearSum[year] = yearSum[year] + 1
}
}
output += '<table border="1">';
output += '<tr><th>Years</th><th>Tally</th></tr>';
const keys = Object.keys(yearSum)
const values = Object.values(yearSum)
for (i = 0; i < keys.length; i++) {
output += '<tr><td>' + keys[i] + '</td><td>';
output += values[i]
output += '</td></tr>';
}
output += '</table>';
document.writeln(output);
return year;
return count;
}
//Tallying Dates?
}
並聲明 yearSum 為
const yearSum = {}
