将列表迭代到表

arr.map((x) => {
tableData += '<tr><td>' + x.highPrice + '</td><td>' + x.lowPrice + '</td></tr>';  
});
$('table').find('tbody').html(tableData)

var tableData = ''
arr.map((x) => {
tableData += '<tr><td>' + x.highPrice + '</td><td>' + x.lowPrice + '</td></tr>';  
});
$('table').find('tbody').html(tableData)

您可能不需要为symbol、highPrice和lowPrice创建单独的数组

相反，您可以使用循环遍历json数组并获取每个项

var table = document.getElementById("myTable");
for(var i =0; i < data.length; i++) {
    var row = table.insertRow(0);
    var cell1 = row.insertCell(0);
    var cell2 = row.insertCell(1);
    var cell3 = row.insertCell(2);
    cell1.innerHTML =  data[i].symbol;
    cell2.innerHTML = data[i].highPrice;
    cell3.innerHTML = data[i].lowPrice;
}

试试这个：

var _tr = '<tr><td>'+item.symbol+'</td><td>'+item.highPrice+'</td><td>'+item.lowPrice+'</td></tr>'
_tbody+=_tr
})
$('#demoTable').append(_tbody)

_myJson.forEach(function(item){
var _tr = '<tr><td>'+item.symbol+'</td><td>'+item.highPrice+'</td><td>'+item.lowPrice+'</td></tr>'
_tbody+=_tr
})
$('#demoTable').append(_tbody)
