我对JavaScript很陌生,有人帮我编写了这个脚本,它在Chrome上效果很好,但它在Firefox中不起作用,并且还没有在IE中测试过,但我希望它能够在所有浏览器,我真的不知道那的jQuery高达翻译它什么在这里混淆了我的跨浏览器功能?
function displayTotal()
{
var tableRows = document.getElementById('budgetTable').getElementsByTagName('tr');
var totalDays = tableRows.length - 3; //Don't count the header rows and the Total rows
var totalPrice = 0;
var price = filterNum(document.getElementById('txtPrice').value);
var totalField = document.getElementById('txtTotal');
var tempHours = 0;
var tempTotal = 0;
for(var i = 0; i < totalDays; i++)
{
tempHours = document.getElementById("end" + i).value - document.getElementById("start" + i).value;
tempTotal = tempHours * price;
document.getElementById("total" + i).innerHTML = formatCurrency(tempTotal);
totalPrice += tempTotal;
console.log(i, "Start:" + document.getElementById("start" + i).value, "End:" + document.getElementById("end" + i).value, "Hours:" + tempHours, "Total:" + tempTotal);
}
totalField.value = formatCurrency(totalPrice);
}
function addRowToTable()
{
var tbl = document.getElementById('budgetTable');
var lastRow = tbl.rows.length - 2;
var iteration = lastRow;
var entry = iteration - 1; //because we started with day0, etc
var row = tbl.insertRow(lastRow);
// day cell
var cellDay = row.insertCell(0);
cellDay.appendChild(createInput('text','day' + entry, '', displayTotal));
// start cell
var cellStart = row.insertCell(1);
cellStart.appendChild(createInput('text','start' + entry, 0, displayTotal));
// end cell
var cellEnd = row.insertCell(2);
cellEnd.appendChild(createInput('text','end' + entry, 0, displayTotal));
// total cell
var cellTotal = row.insertCell(3);
cellTotal.id = 'total' + entry;
}
function createInput(type, id, value, action)
{
var el = document.createElement('input');
el.type = type;
el.id = id;
el.value = value;
el.onkeyup = action;
return el;
}
function filterNum(str)
{
re = /^\$|,/g;
// remove "$" and ","
return str.replace(re, "");
}
function formatCurrency(num)
{
num = isNaN(num) || num === '' || num === null ? 0.00 : num;
return parseFloat(num).toFixed(2);
}
任何帮助将受到欢迎,因为我真的不知道我失去了再点这里。
编辑:好吧,这很奇怪,但在Firefox上,当我启用萤火虫试图调试它时,...它的工作原理。
@ la_f0ka:您在Firefox中遇到什么错误?你之前用过萤火虫吗? – shane87 2011-05-06 14:30:50
'totalDays = tableRows.length-3'是多余的。如果你想跳过'header'行,定义一个thead和tbody。然后,你可以将一个id放在tbody上并获取这些行或者getElementById('budgetTable')。getElementsByTagName(“tbody”)[0] .length – Gary 2011-05-06 14:36:26
“It does not work”is * never * a good error description。请告诉出了什么问题,预期的行为是什么,以及如果您在控制台中收到错误消息。 – 2011-05-06 14:37:03
