Html - 傳遞地址必須將輸入的值賦予帳單地址。在JavaScript和HTML在不同的文件當單擊複選框時,使用複選框將字段中輸入的值顯示到另一個字段
其他JS功能都工作正常,但它只是這一次似乎沒有工作
<div class="textinput">
<label for="deladdress">Delivery Address: </label>
<input id="deladdress" type="text" name="Delivery Address" />
</div>
<div id="buttoncheckarea">
<input id="CheckDelivery" type="checkbox" name="CheckDelivery">
<label id="diff" for="CheckDelivery">Same as delivery address?</label>
</div>
<div class="textinput">
<label for="postcode">Postcode: </label>
<input id="postcode" type="text" name="postcode" />
</div>
<div class="textinput">
<label for="billaddress">Billing Address: </label>
<input id="billaddress" type="text" name="Billing Address" />
</div>
的JavaScript
function deliveryfunc() {
var delivery = document.getElementById("deladdress").value;
var billing = document.getElementById("billaddress").value;
//var checkbox = document.getElementById("CheckDelivery").checked;
if (document.getElementsByName("CheckDelivery").checked == true) {
billing = delivery;
}
}
function init() {
var order = document.getElementById("ordForm");
order.onsubmit = ordervalidation;
order.onclick = radiobuttoncheck;
var checkbutton = document.getElementsByName("CheckDelivery");
checkbutton.onclick = deliveryfunc;
}
window.onload = init;
我試過了,它仍然不適合我。 – Nate
找到了問題,你正在使用'getElementsByName',它返回一個集合[getElementsByName](http://www.w3schools.com/jsref/met_doc_getelementsbyname.asp)。通過將其更改爲'getElementByName',代碼將起作用,更新答案。 – mergenchik
也可以使用'document.getElementsByName(「CheckDelivery」)[0]'這將返回名爲CheckDelivery的第一個元素 – mergenchik
