我不知道我的代码有什么问题,但是当我使用addEventListener()时,它不会执行任何操作。addEventListener onClick不工作
有没有人有另一种解决方案,以便我可以将#ibm按钮ID绑定到compute()onClick事件?
我打算在Firfox操作系统上运行此操作,因此在按钮本身上设置onClick属性是禁止的,如CSP违规中所述。
function compute()
{
var w = parseInt(document.getElementById('weight').value);
var hf = parseInt(document.getElementById('height_ft').value);
var hi = parseInt(document.getElementById('height_in').value);
if (!checker(w))
{
showAndroidToast('Please input your weight');
return;
}
else if (!checker(hf))
{
showAndroidToast('Please input your height');
return;
}
if (!checker(hi))
{
var i = 0;
document.getElementById('height_in').value = i;
}
else
{
var i = parseInt(document.getElementById('height_in').value);
}
var comp_h = parseFloat((hf * 12) + (i * 1));
var tot_h = comp_h * comp_h;
comp = formula(w, tot_h);
document.getElementById('bmitot').value = comp;
if (comp > 30)
{
document.getElementById('res').value = 'Severe Level! Thats too much FAT! Go get some diet pills or something!';
document.getElementById("bmitot").style.backgroundColor = "red";
document.getElementById("zero").style.visibility = "hidden";
document.getElementById("one").style.visibility = "hidden";
document.getElementById("two").style.visibility = "hidden";
document.getElementById("three").style.visibility = "visible";
}
if (comp > 25 && comp <=29.9)
{
document.getElementById('res').value = 'Bad Level! You are too FAT!';
document.getElementById("bmitot").style.backgroundColor = "yellow";
document.getElementById("zero").style.visibility = "hidden";
document.getElementById("one").style.visibility = "hidden";
document.getElementById("two").style.visibility = "visible";
document.getElementById("three").style.visibility = "hidden";
}
if (comp > 18.5 && comp <=24.9)
{
document.getElementById('res').value = 'Nice! You are on the safe level!';
document.getElementById("bmitot").style.backgroundColor = "green";
document.getElementById("zero").style.visibility = "hidden";
document.getElementById("one").style.visibility = "visible";
document.getElementById("two").style.visibility = "hidden";
document.getElementById("three").style.visibility = "hidden";
}
if (comp < 18.5)
{
document.getElementById('res').value = 'Bad Level! Go get some nutrients!';
document.getElementById("bmitot").style.backgroundColor = "yellow";
document.getElementById("zero").style.visibility = "visible";
document.getElementById("one").style.visibility = "hidden";
document.getElementById("two").style.visibility = "hidden";
document.getElementById("three").style.visibility = "hidden";
}
}
function formula(w, h)
{
var bmi = w/h * 703;
var a_bmi = Math.floor(bmi);
var dif = bmi - a_bmi;
dif = dif * 10;
diff = Math.round(dif);
if (dif == 10)
{
a_bmi += 1;
dif = 0;
}
bmi = a_bmi + "." + diff;
return bmi;
}
function checker(type)
{
if (isNaN(parseInt(type)))
{
return false;
}
else if (type < 0)
{
return false;
}
else
{
return true;
}
}
function showAndroidToast(toast)
{
Android.showToast(toast);
}
document.getElementById('ibm').addEventListener('click', compute);
你为什么使用测试?我的代码真的有问题吗?即使当我使用我的浏览器运行代码时,它也不会执行任何操作。 –
我无法真正使用您的代码,因为有像“Android.showToast(toast)”这样的函数不会在我的本地工作,而且我也没有没有完整的html来寻找'weight','height_ft'等等......我需要一个最小的测试用例来检查事件是否正在执行。 –
@MarcusAng他试图创建一个[SSCCE](http://sscce.org/),这是调试编码问题的正确方法。 – jbabey
