最近，我发布了如何将变量实现为innerHTML以在在线测验中使用。结果是变量在我的代码中被意外声明为字符串。我摆脱了引号，网页又恢复了工作。之后添加不同的句子，如＆＃34;你的分数是11/11。你以满分为标准进行测试。不要太兴奋，这只是一个简单的部分。＆＃34;对于测验的每个部分，我为每个部分分配了一个不同的分数变量，以便用户可以看到他们在测试后的表现。例如，easy部分得到了它自己的得分变量escore，这是通过在测验期间将该变量设置为该特定时间的当前得分而创建的。这就是我留下的：
function eqs() {
var escore = score;
if (escore < 4) {document.getElementById("sum1").innerHTML = "Well done for completing the easy questions! Your score was: " + escore + "/ 10. If you're reading this message, you got below 4 marks. Considering that this the easy section, you should've got a much higher score.";}
if (escore > 4 && < 7) {document.getElementById("sum1").innerHTML = "Well done for completing the easy questions! Your score was: " + escore + "/ 10. You didn't get a bad score, but neither did you get a good score. If you were guessing, consider yourself lucky.";}
if (escore > 7 && < 10) {document.getElementById("sum1").innerHTML = "Well done for completing the easy questions! Your score was: " + escore + "/ 10. You got a fairly decent score. Typically, you should get 11, but you're not far off.";}
if (escore == 11) {document.getElementById("sum1").innerHTML = "Well done for completing the easy questions! Your score was: " + escore + "/ 10. Nice job! You aced this section with full marks! Don't get too excited though, this is only the easy section.";}
}
什么都没出现，所以我决定添加一个警报，只要执行该功能就会显示一个弹出屏幕，告诉我得分的值。我重新测试了它，但再次没有出现。这一次，我扫描了整个文件，以确保我没有错过任何愚蠢的错误。我哪里错了？ （如果我把所有这些都写成一个愚蠢的错误而我设法不看......那将是如此具有讽刺意味......）

答案 2 :(得分：0)
正如其他人所说，您需要像if (escore > 4 && escore < 7)这样进行比较。您还需要通过调用它来执行此功能。标识为<p id="sum1"></p>的{{1}}父容器有#eqsummary个类，因此它将被隐藏。
您可以将collapse传递给它，而不是在escore函数内重新声明eqs，这会使您的函数变得模块化。
我猜您的代码仍在进行中，但这里是您问题中问题的解决方案
score$(document).ready(function(){
var score = 0;
var seconds = 0;
$('[data-toggle="tooltip"]').tooltip();
function add1() {score += 1;}
function add2() {score += 2;}
function add3() {score += 3;}
function eqs(escore) {
var sumContainer = document.getElementById("sum1");
if (escore < 4) {
sumContainer.innerHTML = "Well done for completing the easy questions! Your score was: " + escore + "/ 10. If you're reading this message, you got below 4 marks. Considering that this the easy section, you should've got a much higher score.";
}
if (escore > 4 && escore < 7) {
sumContainer.innerHTML = "Well done for completing the easy questions! Your score was: " + escore + "/ 10. You didn't get a bad score, but neither did you get a good score. If you were guessing, consider yourself lucky.";
}
if (escore > 7 && escore < 10) {
sumContainer.innerHTML = "Well done for completing the easy questions! Your score was: " + escore + "/ 10. You got a fairly decent score. Typically, you should get 11, but you're not far off.";
}
if (escore === 11) {
sumContainer.innerHTML = "Well done for completing the easy questions! Your score was: " + escore + "/ 10. Nice job! You aced this section with full marks! Don't get too excited though, this is only the easy section.";
}
}
add1();
add2();
add3();
eqs(score);
