問(wèn)題：為什么我的對(duì)象沒(méi)有將數(shù)據(jù)填充到圖表中？背景：我正在創(chuàng)建一個(gè)財(cái)務(wù)計(jì)算器，在成功提交后，會(huì)向用戶顯示帶有年度計(jì)算的條形圖。問(wèn)題：看起來(lái)我的變量var json和var stringData正在捕獲數(shù)據(jù)，但是當(dāng)我將它們中的任何一個(gè)傳遞給我的chart.data()變量（例如chart.data = [stringData];）時(shí)，數(shù)據(jù)沒(méi)有填充到表中。我已經(jīng)環(huán)顧 Stack Overflow 尋求有關(guān)此問(wèn)題的一些幫助，但我還沒(méi)有找到任何實(shí)質(zhì)性內(nèi)容。任何幫助將非常感激！有問(wèn)題的行：我認(rèn)為可以仔細(xì)檢查的代碼行是69、82-85、91和102 行。圖表中工作數(shù)據(jù)的 JSFiddle 示例：https://jsfiddle.net/yL3c6s1j/1/演示：$('#submit').click(function() {  var name = $('#name'),    age = $('#age'),    retAge = $('#retAge'),    retPackage = $('#retPackage'),    contribution = $('#annualContribution'),    rate = $('#annualRateReturn'),    display = $('#display');  var nameVal = name.val(),    ageVal = age.val(),    retAgeVal = retAge.val(),    workingYears = retAgeVal - ageVal,    retPackageVal = parseFloat(retPackage.val()),    contributionVal = parseFloat(contribution.val()),    rateVal = parseFloat(rate.val());  if (nameVal === '' || ageVal === '' || ageVal > retAgeVal || retAgeVal === '' || retAgeVal < ageVal || isNaN(retPackageVal) || isNaN(contributionVal) || isNaN(rateVal)) {    // Hides DOM response after unsuccessful form submission    display.hide();    // Checks for empty name    if (nameVal === '') {      name.addClass('error');    } else {      name.removeClass('error');    }    // Checks for empty age or if age is greater than retirement age    if (ageVal === '' || ageVal > retAgeVal) {      age.addClass('error');    } else {      age.removeClass('error');    }    // Checks for empty retirement age or if retirement age is less than age    if (retAgeVal === '' || retAgeVal < ageVal) {      retAge.addClass('error');    } else {      retAge.removeClass('error');    }    // Checks for empty current 401(k) value    if (isNaN(retPackageVal)) {      retPackage.addClass('error');    } else {      retPackage.removeClass('error');    }
