- html - 出于某种原因,IE8 对我的 Sass 文件中继承的 html5 CSS 不友好?
- JMeter 在响应断言中使用 span 标签的问题
- html - 在 :hover and :active? 上具有不同效果的 CSS 动画
- html - 相对于居中的 html 内容固定的 CSS 重复背景?
我有一个简单的 JavaScript 代码,但它不起作用。我的代码是:
<html>
<head>
<title>JavaScript</title>
<script>
var target;
var guess_input;
var guesses = 0;
var finished = false;
var colors = ["black","blue","green","purple","red","white","yellow"];
function do(){
var random = Math.random();
var index = Math.floor(random * 7);
target = colors[index];
while(!finished){
guess_input = prompt("I am thinking of a color : black, blue, green, purple, red, white \n\n" + "What color am i thinking of?");
guesses++;
finished = check();
}
var myBody = document.getElementsByTagName("body")[0];
myBody.style.background = target;
}
function check(){
if (guess_input > target){
alert("your color is alphabetically higher than mine");
return false;
}
if (guess_input < target){
alert("your color is alphabetically lower than mine");
return false;
}
if (guess_input == target){
alert("your color is correct! it tooks you" + guesses "guesses to finish the game!");
return true;
}
else {
alert("Sorry, I do not recoginize your color");
return false;
}
</script>
</head>
<body onload = "do()">
</body>
</html>
错误消息是:Uncaught SyntaxError: Unexpected token dopart2.html:53 Uncaught SyntaxError: Unexpected token ),即“function do()”,那么问题出在哪里呢?谢谢!
最佳答案
您缺少用于函数检查的右括号并将 do 函数名称更改为其他函数,例如 doSomething
<html>
<head>
<title>JavaScript</title>
<script>
var target;
var guess_input;
var guesses = 0;
var finished = false;
var colors = ["black","blue","green","purple","red","white","yellow"];
function doSomething(){
var random = Math.random();
var index = Math.floor(random * 7);
target = colors[index];
while(!finished){
guess_input = prompt("I am thinking of a color : black, blue, green, purple, red, white \n\n" + "What color am i thinking of?");
guesses++;
finished = check();
}
var myBody = document.getElementsByTagName("body")[0];
myBody.style.background = target;
}
function check(){
if (guess_input > target){
alert("your color is alphabetically higher than mine");
return false;
}
if (guess_input < target){
alert("your color is alphabetically lower than mine");
return false;
}
if (guess_input == target){
alert("your color is correct! it tooks you" + guesses "guesses to finish the game!");
return true;
}
else {
alert("Sorry, I do not recoginize your color");
return false;
}
}
</script>
</head>
<body onload="doSomething()">
</body>
</html>
