基本上,如果用户想要将它们发送到收件人电子邮件,我会尝试根据用户选择的数量显示 1 到 10 个文本框。
我有一个下拉选择,其中包含 1-10 个选项/值、两个单选按钮和十个支持 div 的文本框。我正在使用以前的开发人员(我所占据的位置)使用的代码片段,我只能假设它是 jQuery,但我有一些我所拥有的小 Javascript 知识与它混合在一起。不确定我是否可以这样做。:/ Javascript/jQuery 是我的克星。
这是我到目前为止所拥有的(实时服务器): http: //www.dealraiser.net/gift
使用的 Javascript/jQuery:
<script type="text/javascript">
// SHOW HIDDEN TEXTBOXES
function updateDisplay(select) {
// ACCESS RADIO OBJECT
var radioValue = getRadioCheckedValue('sending');
// SHOW FIELD IF RADIO IS SET TO 'R'
if (radioValue == 'r') { showField(); }
}
// BORROWED FROM GOOGLE - EASIER TO USE PRE-EXISTING
function getRadioCheckedValue(radio_name) {
var oRadio = document.forms[0].elements[radio_name];
for(var i = 0; i < oRadio.length; i++) {
if(oRadio[i].checked) {
return oRadio[i].value;
}
}
return '';
}
// DISPLAY FIELD, HIDE OTHERS
function showField() {
// HIDE ALL EXTRA OPTIONS
for (i=1, i<10, i++) {
$("#re"+i).hide();;
$('#r'+i).removeClass('required');
}
if (radio.value == 'r') {
// DETERMINE NUMBER OF EMAILS TO SHOW
var giftNumber = document.getElementById('giftnumber').value;
// DISPLAY ONLY THE RIGHT AMOUNT OF EMAIL INPUTS
for (i=1, i<=giftNumber, i++) {
$("#re"+i).show();
$('#r'+i).addClass('required');
}
}
}
// TOGGLE RADIO ON/OFF
function doToggle(radio) {
// HIDE ALL EXTRA OPTIONS
for (i=1, i<10,i++) {
$("#re"+i).hide();
$('#r'+i).removeClass('required');
}
if (radio.value == 'r') {
// DETERMINE NUMBER OF EMAILS TO SHOW
var giftNumber = document.getElementById('giftnumber').value;
// DISPLAY ONLY THE RIGHT AMOUNT OF EMAIL INPUTS
for (i=1, i<=giftNumber, i++) {
$("#re"+i).show();
$('#r'+i).addClass('required');
}
}
}
</script>
这是HTML:
