我无法得到指数，百分比，我的JavaScript网络应用程序上的平方根按钮都不适用于我的生活！编辑在分析时没有向我显示任何问题，所以我不知道问题是什么。你能看到我的代码中可能出现错误的地方吗？

答案 0 :(得分：0)
对于sqrt函数，缺少值：
function sqrt_function() {
flag += 1;
calc.display.value = Math.sqrt(calc.display.value);
}
对于百分比，它是javascript中的模数，我尝试了6％5，其中1为您的工具，这很好。 如果你想要百分比，你只需要除以100。
calc.display.value = calc.display.value / 100;
对于你的日志，你要连接值，我认为这是错误的：
calc.display.value+=1.442
对于你的指数，缺少（）
<input class="button third row" type="button" value="EXP" onClick="exp_function()">
我猜这将有效
function exp_function() {
flag += 1;
calc.display.value = Math.exp(calc.display.value);
}
如果有帮助，请告诉我。
