【问题描述】：
我得到了以下 Javascript 代码，它在 Mozilla Firefox 中可以正常工作，但在 Google Chrome 中却不能。知道为什么会这样做吗？
即使值是 45，Chrome 中的总BMI（检查所有最后一个按钮会给你的值 45 大于 26 所以结果应该将 hRisk div 设置为display:-inline 而不是display:none，作为函数@987654325 @ 确实。）它仍然认为它是 0，因为它显示低风险消息。在 Firefox 中，它总是显示正确的答案。
Javascript 代码：
function CalculateValue() {
var age = +getAgeValue('age'),
bmi = +getBmiValue('bmi'),
fami = +getFamValue('fam'),
diet = +getDietValue('diet'),
totalBMI = age + bmi + fami + diet;
totalBMI = parseFloat(totalBMI);
alert(totalBMI);
if (totalBMI > 26) {
function changeCSS() {
document.getElementById("btn").onclick = function() {
var hMessage = document.getElementById("hRisk");
hMessage.style.display = 'inline';
/*var newSpan = document.createElement("span");
var newSpanText = document.createTextNode("Your main factors risk are " );
newSpan.appendChild(newSpanText);
var pElem = document.getElementById("space");
pElem.appendChild(newSpan); */
}
}
changeCSS();
} else if (totalBMI > 16 ) {
function changeCSS() {
document.getElementById("btn").onclick = function() {
var mMessage = document.getElementById("mRisk");
mMessage.style.display = 'inline';
}
}
changeCSS();
} else {
function changeCSS() {
document.getElementById("btn").onclick = function() {
var lMessage = document.getElementById("lRisk");
lMessage.style.display = 'inline';
}
}
changeCSS();
}
}
function getAgeValue()
{
for (var i = 0; i < document.getElementsByName('age').length; i++)
{
if (document.getElementsByName('age')[i].checked)
{
return document.getElementsByName('age')[i].value;
}
}
}
function getBmiValue()
{
for (var i = 0; i < document.getElementsByName('bmi').length; i++)
{
if (document.getElementsByName('bmi')[i].checked)
{
return document.getElementsByName('bmi')[i].value;
}
}
}
function getFamValue()
{
for (var i = 0; i < document.getElementsByName('fam').length; i++)
{
if (document.getElementsByName('fam')[i].checked)
{
return document.getElementsByName('fam')[i].value;
}
}
}
function getDietValue()
{
for (var i = 0; i < document.getElementsByName('diet').length; i++)
{
if (document.getElementsByName('diet')[i].checked)
{
return document.getElementsByName('diet')[i].value;
}
}
}

【问题讨论】：
-
我还检查了 [quirksmode.org/dom/core/] DOM CORE，我使用的元素看起来没有任何问题。
-
你试过在上面运行JSLint吗？
-
已修复。就像 fuximus goe 所说的“删除 changeCSS 函数并立即执行它们的代码即可解决问题”，解决了浏览器兼容性问题。
