所以我正在创建一个撤销日历，并且需要对javascript进行一些更改，而不是确定如何。
我创建的所有代码都必须插入到CMS系统中，该系统会删除head / body标记，因此我无法使用onLoad函数。我想要发生的是，一旦他们选择了日期，他们点击提交按钮，然后出现撤销日期。
以下是我们之前系统中未使用CMS的代码：
Startscript language="javascript" type="text/javascript"<br>
hoyDate = new Date;<br>
closeDate = new Date;<br>
fundDate = new Date;<br>
resDate = new Date;<br>
monthsi = new Array('January', 'February', 'March', 'April', 'May', 'June', 'July', 'August', 'September', 'October', 'November', 'December');<br>
daysi = new Array('Sunday', 'Monday', 'Tuesday', 'Wednesday', 'Thursday', 'Friday', 'Saturday');<br>
function setForm() {<br>
document.form.monthy.options.selectedIndex = closeDate.getMonth();<br>
document.form.datey.options.selectedIndex = closeDate.getDate() - 1;<br>
document.form.yeary.value = closeDate.getFullYear();<br>
}<br><br>
function calcRescission() {<br>
closeDate.setMonth(document.form.monthy.options[document.form.monthy.options.selectedIndex].value * 1);<br>
closeDate.setDate(document.form.datey.options[document.form.datey.options.selectedIndex].value * 1);<br>
closeDate.setFullYear(document.form.yeary.value * 1);<br>
<br>
resDate.setTime(closeDate.getTime());<br>
fundDate.setTime(closeDate.getTime());<br>
<br>
for (i=0; i<=2; i++) {<br>
resDate.setTime(resDate.getTime() + (3600000 * 24));<br>

这是HTML：
<body onload="setForm();calcRescission();">
<form name="form" action="rescission.html" method="post">
<table cellpadding="4" cellspacing="0">
<tr>
<td>
<select name="monthy" onchange="calcRescission()" class="editable">
<option value="0">January</option>
<option value="1">February</option>
<option value="2">March</option>
</select>
<select name="datey" onchange="calcRescission()" class="editable">
<option value="1">1</option>
<option value="2">2</option>
<option value="3">3</option>
</select>
<input name="yeary" onkeyup="calcRescission()" size="7" class="editable">
</td>
</tr>
<tr>
<td>
<input name="rescissionmonthy" readonly size="10" class="rescind">
<input name="rescissiondatey" readonly size="3" class="rescind">
<input name="rescissionyeary" readonly size="7" class="rescind">
</td>
</tr>
</table>
</form>
答案 0 :(得分：1)
你将摆脱这个：
<body onload="setForm();calcRescission();">
并将其添加到脚本中：
document.getElementsByTagName("body")[0].addEventListener("load", function() {
setForm();calcRescission()
}, false);
