这是我想要实现的目标:我想创建一个带有表单的 HTML 页面,当您提交表单时,它会转到 4 个位置中的 1 个。有一个在页面加载时自动选择的默认隐藏主选项和 2 个可选的子选项。
哦,它会计算选择的数量!
到目前为止,这是我的代码:
<html>
<head></head>
<body>
<form onSubmit="submitForm();" id="myForm" type="get">
<input id="myCheckbox1" name="myCheckbox1" type="checkbox" value="20" onClick="calcNow();" />Default option<br/>
<input id="myCheckbox2" name="myCheckbox2" type="checkbox" value="30" onClick="calcNow();" />Add-on option 1<br/>
<input id="myCheckbox2" name="myCheckbox2" type="checkbox" value="40" onClick="calcNow();" />Add-on option 2<br/>
<input id="myTotal" name="myTotal" type="text" value="" disabled="disabled" /><br/>
<input type="button" id="myButton" onClick="submitForm();" value="Continue" />
</form>
<script type="text/javascript">
var pages = [[["http://mysite.com/page1.html"],["http://mysite.com/page2.html"],["http://mysite.com/page3.html","http://mysite.com/page4.html"]]];
function calcNow()
{
var cb = document.getElementById("myCheckbox1");
var cb = document.getElementById("myCheckbox2");
var cost1 = cb.checked ? parseInt(cb.value) : 0;
var cost2 = cb.checked ? parseInt(cb.value) : 0;
var costTotal = cost1 + cost2;
document.getElementById("myTotal").value = costTotal;
var op1 = cb.checked ? 1 : 0;
if (op1 != undefined)
{
return pages[op1];
}
return undefined;
}
function submitForm()
{
var page = calcNow();
if (page != undefined)
{
alert(page);
// ---- To navigate ----
//location.href = page;
// ---- To alter post ----
//var form = document.getElementById("myForm");
//form.action = page;
//form.submit();
}
else
{
alert("Please answer all questions.");
}
}
function getRadioValue(name)
{
var controls = document.getElementsByName(name);
for (var i = 0; i < controls.length; i++) {
if (controls[i].checked) {
return parseInt(controls[i].value);
}
}
return 0;
}
function getRadioData(name, attribute)
{
var controls = document.getElementsByName(name);
for (var i = 0; i < controls.length; i++) {
if (controls[i].checked) {
return parseInt(controls[i].dataset[attribute]);
}
}
return undefined;
}
