Question

我正在尝试制作“我应该参加这个测试还是那个测试”计算器。当我同时输入两个值时，什么也不会输出，所以我正在寻找代码中的错误。谢谢！

SELECT
* FROM
`table1`,
`table2`,
`table3`,
`table4`,...
`table12`,
  WHERE
(
    (
        `table1`.`columnlast` LIKE '%string%'
    ) OR(
        `table2`.`columnlast' LIKE '%string%'
    ) OR(
        `table3`.`columnlast` LIKE '%string%'
    )...

    ) OR(
        `table12`.`columnlast` LIKE '%string%'
    )

document.getElementById("test2score").onkeyup = function() {
  WhichTestFunction()
};

function WhichTestFunction() {
  var t1 = document.getElementById('test1score').value;
  var t2 = document.getElementById('test2score').value;

  if (t1 == 9) && (t2 < 120) {
    score = "Take Test 1";
  }

  else if (t1 == 9) && (t2 > 140) {
    score = "Take Test 2";
  }

  else if (act == 9) && (sat >= 120) && (sat <= 140) {
    score = "Toss up. Take the test you like better based on format and content.";
  }

  document.getElementById("testscore").innerHTML = score;
}

Answer 1

首先，您需要使用外部括号将if语句包装起来

if ((act == 9) && (sat >= 120) && (sat <= 140)) {...}

然后您有几个未声明的变量导致异常

var score, sat, act;

注释1a：我不知道这3个变量是否应该全局声明/可用。

注释1b：由于不知道它们的实际含义，因此我注释掉了最后一个if语句，因此该代码将在此演示示例中运行。
