【问题描述】：
我是编程新手，我在 JavaScript 中尝试了一些东西，它在 Chrome 中运行良好。但它无法在 IE、Firefox、Safari 和 Opera 中运行。我的代码有什么问题吗？
function hp(form) {
var count1 = 0, count2 = 0, count3 = 0, count4 = 0, count5 = 0, count6 = 0, count7 = 0, count8 = 0, count9 = 0, count10 = 0;
for (var i = 0; i < 3; i++) {
if (form.q1[i].checked == true) {
count1++;
}
}
if (count1 !== 1) {
alert("Please Answer 1st Question");
return false;
}
for (var i = 0; i < 3; i++) {
if (form.q2[i].checked == true) {
count2++;
}
}
if (count2 !== 1) {
alert("Please Answer 2nd Question");
return false;
}
for (var i = 0; i < 3; i++) {
if (form.q3[i].checked == true) {
count3++;
}
}
if (count3 !== 1) {
alert("Please Answer 3rd Question");
return false;
}
for (var i = 0; i < 3; i++) {
if (form.q4[i].checked == true) {
count4++;
}
}
if (count4 !== 1) {
alert("Please Answer 4th Question");
return false;
}
for (var i = 0; i < 3; i++) {
if (form.q5[i].checked == true) {
count5++;
}
}
if (count5 !== 1) {
alert("Please Answer 5th Question");
return false;
}
for (var i = 0; i < 3; i++) {
if (form.q6[i].checked == true) {
count6++;
}
}
if (count6 !== 1) {
alert("Please Answer 6th Question");
return false;
}
for (var i = 0; i < 3; i++) {
if (form.q7[i].checked == true) {
count7++;
}
}
if (count7 !== 1) {
alert("Please Answer 7th Question");
return false;
}
for (var i = 0; i < 3; i++) {
if (form.q8[i].checked == true) {
count8++;
}
}
if (count8 !== 1) {
alert("Please Answer 8th Question");
return false;
}
for (var i = 0; i < 4; i++) {
if (form.q9[i].checked == true) {
count9++;
}
}
if (count9 !== 1) {
alert("Please Answer 9th Question");
return false;
}
for (var i = 0; i < 3; i++) {
if (form.q10[i].checked == true) {
count10++;
}
}
if (count10 !== 1) {
alert("Please Answer 10th Question");
return false;
}
answer1 = (form.q1.value);
answer2 = (form.q2.value);
answer3 = (form.q3.value);
answer4 = (form.q4.value);
answer5 = (form.q5.value);
answer6 = (form.q6.value);
answer7 = (form.q7.value);
answer8 = (form.q8.value);
answer9 = (form.q9.value);
answer10 = (form.q10.value);
var a = parseInt(answer1);
var b = parseInt(answer2);
var c = parseInt(answer3);
var d = parseInt(answer4);
var e = parseInt(answer5);
var f = parseInt(answer6);
var g = parseInt(answer7);
var h = parseInt(answer8);
var ii = parseInt(answer9);
var j = parseInt(answer10);
var c = a + b + c + d + e + f + g + h + ii + j;
//document.getElementById("result").innerHTML= "The selected values are "+"</br>"+a+"</br>"+b+c+d+e+f+g+h+ii+j+"</br>"+c;
if (c <= 20) {
document.getElementById("total").innerHTML = "<h3>" + "ABCD" + "</h3>" + "</br>" + "<IMG ALIGN='center' " + "SRC='images/img.png'>";
}
else if ((c > 20) && (c <= 25)) {
document.getElementById("total").innerHTML = "<h3>" + "ABCD" + "</h3>" + "</br>" + "<IMG ALIGN='center' " + "SRC='images/img.png'>";
}
else if ((c > 25) && (c <= 30)) {
document.getElementById("total").innerHTML = "<h3>" + "ABCD" + "</h3>" + "</br>" + "<IMG ALIGN='center' " + "SRC='images/img.png'>";
}
else if ((c > 30) && (c <= 40)) {
document.getElementById("total").innerHTML = "<h3>" + "ABCD" + "</h3>" + "</br>" + "<IMG ALIGN='center' " + "SRC='images/img.png'>";
}
else if ((c > 40) && (c <= 50)) {
document.getElementById("total").innerHTML = "<h3>" + "ABCD" + "</h3>" + "</br>" + "<IMG ALIGN='center' " + "SRC='images/img.png'>";
}
else if ((c > 50) && (c <= 60)) {
document.getElementById("total").innerHTML = "<h3>" + "ABCD" + "</h3>" + "</br>" + "<IMG ALIGN='center' " + "SRC='images/img.png'>";
}
else if ((c > 60) && (c <= 65)) {
document.getElementById("total").innerHTML = "<h3>" + "ABCD" + "</h3>" + "</br>" + "<IMG ALIGN='center' " + "SRC='images/img.png'>";
}
else if ((c > 65) && (c <= 75)) {
document.getElementById("total").innerHTML = "<h3>" + "ABCD" + "</h3>" + "</br>" + "<IMG ALIGN='center' " + "SRC='images/img.png'>";
}
else if ((c > 75) && (c <= 90)) {
document.getElementById("total").innerHTML = "<h3>" + "ABCD" + "</h3>" + "</br>" + "<IMG ALIGN='center' " + "SRC='images/img.png'>";
}
c = 0;
}
我在本地主机上尝试了这段代码，并在 Google Chrome 中得到了我想要的输出。当我在 Firefox 和其他浏览器中尝试相同的页面时，它无法正常工作。只有复选框验证工作正常。 提前致谢
【问题讨论】：
-
您是否在控制台中遇到任何错误？右键单击 - 检查元素。 firefox用firebug、IE f12等？
-
控制台给我这个错误 HTML 文档的字符编码没有声明。如果文档包含 US-ASCII 范围之外的字符，则文档将在某些浏览器配置中呈现乱码。页面的字符编码必须在文档或传输协议中声明。
-
@AmarIlindra 那将是 HTML 编码的问题，您将 HTML 编码设置为什么？
-
基于该错误，您的 HTML 中可能缺少一个标签 - 与您的 JS 无关。确保您的 HTML 具有用于编码的元标记，例如：
<meta charset="UTF-8">... 在您的 JS 中，请记住“不要重复自己”。无论total的值如何，您的最后几行都执行完全相同的操作 - 不需要所有那些 else/if 语句。上面，试着想想如何创建一个函数来计算计数并使用单个代码块而不是 10 个运行 for 循环。使用浏览器中的控制台/开发人员工具来调试和跟踪问题。坚持下去！ :) -
即使在添加后 仍然存在同样的问题，但这次控制台没有错误。还有其他建议吗？谢谢
