我有以下代码。除了我希望将最终的tintotal变量四舍五入到最接近的1(2.04被四舍五入到3等)之外,效果还不错
$(document).ready(function(){
// Animate logo
$('#Logo').hide().fadeIn(800);
// Calculation Scripts
// Square Metres
var output = $('#SquareMetres'),
tinoutput = $('#Tins'),
priceoutput = $('#Price');
$('input[type="text"]').keyup(function() {
var width = parseFloat( $('#width').val()),
height = parseFloat( $('#height').val()),
result = height * width / 10000,
finalresult = result.toFixed(2);
if (isNaN(result)) return;
output.text(finalresult);
// Tins
var tinmetres = 32.5,
tinprice = 18.23,
tinsresult = finalresult / tinmetres;
tinstotal = tinsresult.toFixed(2);
tinoutput.text(tinstotal);
var price = tinstotal * tinprice,
totalprice = price.toFixed(2);
priceoutput.text('£'+totalprice)
});
});
该脚本在底部附近红色框中的http://andyholmes.me/sitewizard/index.html处处于活动状态。希望你们能有所帮助,谢谢!
最佳答案
tinstotal = Math.ceil(tinsresult);
tinoutput.text(tinstotal);
Math.ceil()将四舍五入到下一个整数
