Question

前一段时间我制作了一个javascript计算器，现在我又在另一个项目中重复使用它。问题是，它甚至不再显示在页面上。这是calc.html文件的代码。

{% extends 'base.html' %}

{% block body %}

<div class="text-center">
    <h1>Calculator</h1>
</div>
<div id="JSCalc">
    <form name="calculator">
        <input type="text" name="answer"/>
        <br />
        <input type="button" value=" 7" onclick="calculator.answer.value += '7'"/>
        <input type="button" value=" 8" onclick="calculator.answer.value += '8'"/>
        <input type="button" value=" 9" onclick="calculator.answer.value += '9'"/>
        <input type="button" value=" *" onclick="calculator.answer.value += '*'"/>
        <br />
        <input type="button" value=" 4" onclick="calculator.answer.value += '4'"/>
        <input type="button" value=" 5" onclick="calculator.answer.value += '5'"/>
        <input type="button" value=" 6" onclick="calculator.answer.value += '6'"/>
        <input type="button" value=" -" onclick="calculator.answer.value += '-'"/>
        <br />
        <input type="button" value=" 1" onclick="calculator.answer.value += '1'"/>
        <input type="button" value=" 2" onclick="calculator.answer.value += '2'"/>
        <input type="button" value=" 3" onclick="calculator.answer.value += '3'"/>
        <input type="button" value=" +" onclick="calculator.answer.value += '+'"/>
        <br />
        <input type="button" value=" 0" onclick="calculator.answer.value += '0'"/>
        <input type="button" value=" C" onclick="calculator.answer.value = ''"/>
        <input type="button" value=" =" onclick="calculator.answer.value = eval(calculator.answer.value)"/>
        <input type="button" value=" /" onclick="calculator.answer.value += '/'"/>
        <br />
    </form>
</div>

{% endblock %}

这是它延伸的base.html文件。请注意，这不是由我写的，我只是想让计算器与它一起工作，而我却没有看到它是什么阻止了它。

你说你需要访问：

http://localhost:8000/calc.html（calc.html）

那你还没定义那个对吗？您正尝试访问：

http://localhost:8000/calc（计算）

您的代码：

<input type="submit" class="blue" value="Calculator" onclick="window.open('http://localhost:8000/calc','_blank','height=425,width=425')" />

试试这个：

<input type="submit" class="blue" value="Calculator" onclick="window.open('http://localhost:8000/calc.html','_blank','height=425,width=425')" />

为什么我的javascript计算器不能与base.html一起使用？
