Question

我一直在尝试在另一个html文件中的javascript文件中使用一个函数。从本质上讲，它不起作用，我认为这与我尝试在html文件上访问javascript有关。该函数应该添加从表单中获取的值，然后输出该总和。代码的第一位是我的.js文件，第二位是我的html。

function reset()
{
	var q = new Array(5);
	
	for(var i = 0; i < 5; i++)
	{
		q[i] = 100;
	}
}

function calculate(form)
{
	var q = new Array(5);
	for(var i = 0; i < 5; i++) {
		q[i] = 100;
	}
	q[1] = document.worksheet1.Q1.options[document.worksheet1.Q1.selectedIndex].value;
	q[2] = document.worksheet1.Q2.options[document.worksheet1.Q2.selectedIndex].value;
	q[3] = document.worksheet1.Q3.options[document.worksheet1.Q3.selectedIndex].value;
	q[4] = document.worksheet1.Q4.options[document.worksheet1.Q4.selectedIndex].value;
	q[5] = document.worksheet1.Q5.options[document.worksheet1.Q5.selectedIndex].value;
	
	var total = (q[1]*1.0)+(q[2]*1.0)+(q[3]*1.0)+(q[4]*1.0)+(q[5]*1.0);
	
	document.worksheet1.totals.value = total;
}

P.s一些额外的问题。我从网站上借了一些代码，因为我对javascript和html都很新。为什么重置功能的数组值都变为100？并且，为什么计算函数不会调用重置函数而不是执行相同的操作？

Answer 1

我只是jscript的新手，这可能不起作用，但可以放手一搏

function reset()
{
    var q = new Array(5);

    for(var i = 0; i < 5; i++)
    {
        q[i] = 100;
    }
}

function calculate() {

    var q = new Array(5);
    for(var i = 0; i < 5; i++) {
        q[i] = 100;
    }
    q[1] = document.worksheet1.Q1.options[document.worksheet1.Q1.selectedIndex].value;
    q[2] = document.worksheet1.Q2.options[document.worksheet1.Q2.selectedIndex].value;
    q[3] = document.worksheet1.Q3.options[document.worksheet1.Q3.selectedIndex].value;
    q[4] = document.worksheet1.Q4.options[document.worksheet1.Q4.selectedIndex].value;
    q[5] = document.worksheet1.Q5.options[document.worksheet1.Q5.selectedIndex].value;

    var total = (q[1]*1.0)+(q[2]*1.0)+(q[3]*1.0)+(q[4]*1.0)+(q[5]*1.0);

    document.worksheet1.totals.value = total;
}

<form name="worksheet1" id="worksheet1" onsubmit="return calculate()">

如何在html中使用javascript函数？
