我在网上搜索但没有找到有用的东西。
我做了一个小小的英语测验。在每个难度部分之后，我希望Javascript进入innerHTML并将变量分数输入到innerHTML中。以下是我必须要做的事情：
function eqs() {document.getElementById("sum1").innerHTML = "Well done for completing the easy questions! Your score was: '+score+'."}
这并没有在我想要的bootstrap jumbotron中显示任何内容。
我稍微改了一下：
function eqs() {document.getElementById("sum1").innerHTML = "Well done for completing the easy questions! Your score was: " + score + "."}
这一次，它显示了011111111。
所有代码：

答案 0 :(得分：1)
当你var score = "0";当你将分数宣布为字符串时 - 而不是数字，所以当你拨打add1（）时，你要追加＆＃39; 1＆＃39;而不是增加价值。
尝试：var score = 0;
编辑：
还有秒：var seconds = 0;或者你在那里遇到同样的问题。
答案 1 :(得分：0)
我检查了你的代码， 它完全正确。但是当你定义得分时，你定义为字符串var score =＆＃34; 0＆＃34;。这就是为什么它没有添加你的分数.. 只需更改此行var score =＆＃34; 0＆＃34 ;;到var score = 0;（删除反转的逗号）。 你很高兴。
