页面后使用Javascript/jQuery的运行脚本，渲染
问题描述：
我试图让从两个功能，correct[]和wrong[]反馈，显示为用户解答问题。我加了jQuery ready功能，试图使我想要的一切提示过，但没有成功出现。我已经将准备就绪的功能写入我的代码几次，但没有运气。任何人都可以帮忙吗？页面后使用Javascript/jQuery的运行脚本，渲染

答
负载后不要使用文件撰写。它抹去页面和脚本。 而是更新标签 - 在这里我使用jQuery的你已经在使用追加答案
// These needed to be and STAY global
// Question array \t \t \t
var question = ["1. What is 1+1?",
"2. What is 2+2?",
"3. What is 3+3?",
"4. What is 4+4?",
"5. What is 5+5?"
];
//Other Variables
var qlength = question.length;
var counter = 0;
var answer = ["2", "4", "6", "8", "10"];
$("document").ready(function() {
$("body").css("background-color", "green");
ask();
$("#result").append("<br>You got " + counter + " answer"+(counter==1?"":"s")+" out of 5 correct.");
});
function ask() {
//First box to tell the viewer whats going on
alert('Answer the following 5 questions to determine if you are 1st grade smart.');
//Loop that asks the questions
for (var i = 0; i < qlength; i++) {
var userAnswer = prompt(question[i]); //Stores the answer to each question in userAnswer
//Actions for correct answer
if (userAnswer == answer[i]) {
alert('Correct');
correct(i);
counter++; //Adds one to the counter for correct answers
}
//Actions for wrong answer
else {
alert('Wrong');
wrong(i);
}
}
}
function correct(i) {
$("#result").append(i + 1, ". Correct" + "<br>");
}
function wrong(i) {
$("#result").append(i + 1, ". Wrong, correct answer = ", answer[i], "<br>");

负荷后不要使用文件撰写。而是使用一些标签的innerHTML或.html（） – mplungjan
清理你的代码。将您的JavaScript代码（显然排除将其链接。 –
此外，不要把你的jQuery脚本之前 –
