我正在研究jQuery计算器。一切都很好,直到几分钟前,现在什么都不会发生。我意外地在代码中插入了一个坏字符吗?我已经上下扫描了几次,但找不到源代码。任何帮助,将不胜感激!基本的jQuery计算器
头:
<script src="http://code.jquery.com/jquery.js"></script>
<link href="css/bootstrap.min.css" rel="stylesheet" media="screen">
<link rel="stylesheet" type="text/css" href="css/style-calc.css">
<script src="js/bootstrap.min.js"></script>
的jQuery:
$(document).ready(function() {
alert("ready");
$('#salary, #transcribing-hours, #cost-of-assistant').keydown(function(e){
var key = e.which;
if (key != 8 && key != 9 && key != 37 && key != 38 && key != 39 && key != 40 && key != 46 && key != 110 && key != 190 && key != 13){
if (key < 48){
e.preventDefault();
}
else if (key > 57 && key < 96){
e.preventDefault();
}
else if (key > 105) {
e.preventDefault();
}
}
});
});
$('#salary').on('input', function() {
var salary = $('#salary').val();
var costofassist = $('#cost-of-assistant').val();
var total = salary/(52 * 40);
var roundtotal = Math.round(total * 100)/100;
$('#hourly-pay-total').text(roundtotal);
});
$('#transcribing-hours').on('input', function() {
var hoursday = $('#transcribing-hours').val();
var hoursweek = hoursday * 5;
var hoursmonth = hoursweek * 4.3;
var hoursyear = hoursweek * 52;
$('#transcribing-year').text(Math.round(hoursyear * 100)/100);
$('#transcribing-month').text(Math.round(hoursmonth * 100)/100);
$('#transcribing-week').text(Math.round(hoursweek * 100)/100);
var roundtotal = $('#hourly-pay-total').text();
var costwithoutyear = (hoursweek * roundtotal) * 52;
var costwithoutmonth = (hoursweek * roundtotal) * 4.3;
var costwithoutweek = hoursweek * roundtotal;
$('#cost-without-year').text(Math.round(costwithoutyear * 100)/100);
$('#cost-without-month').text(Math.round(costwithoutmonth * 100)/100);
$('#cost-without-week').text(Math.round(costwithoutweek * 100)/100);
});
$('#cost-of-assistant').on('input', function() {
var costofassist = $('#cost-of-assistant').val();
var costwithoutyear = $('#cost-without-year').text();
var annualsavings = costwithoutyear - costofassist;
var monthlysavings = annualsavings/12;
var weeklysavings = annualsavings/52;
var dailysavings = annualsavings/260;
$('#annual-savings').text((Math.round(annualsavings * 100)/100);
$('#monthly-savings').text(Math.round(monthlysavings * 100)/100);
$('#weekly-savings').text(Math.round(weeklysavings * 100)/100);
$('#daily-savings').text(Math.round(dailysavings * 100)/100);
});
仅供参考:追踪javascript中任何问题的最佳方法是在谷歌chtome中打开页面,并按下'F12'作为开发模式。它会告诉你这个问题。 –
