我正在尝试在需要的 php 表单中创建一个字段。我正在使用 Dreamweaver Cs3。
Dreamweaver 生成了以下函数
<script type="text/javascript">
<!--
function MM_validateForm() { //v4.0
if (document.getElementById) {
var i, p, q, nm, test, num, min, max, errors = '',
args = MM_validateForm.arguments;
for (i = 0; i < (args.length - 2); i += 3) {
test = args[i + 2];
val = document.getElementById(args[i]);
if (val) {
nm = val.name;
if ((val = val.value) != "") {
if (test.indexOf('isEmail') != -1) {
p = val.indexOf('@');
if (p < 1 || p == (val.length - 1)) errors += '- ' + nm + ' must contain an e-mail address.\n';
} else if (test != 'R') {
num = parseFloat(val);
if (isNaN(val)) errors += '- ' + nm + ' must contain a number.\n';
if (test.indexOf('inRange') != -1) {
p = test.indexOf(':');
min = test.substring(8, p);
max = test.substring(p + 1);
if (num < min || max < num) errors += '- ' + nm + ' must contain a number between ' + min + ' and ' + max + '.\n';
}
}
} else if (test.charAt(0) == 'R') errors += '- ' + nm + ' is required.\n';
}
}
if (errors) alert('The following error(s) occurred:\n' + errors);
document.MM_returnValue = (errors == '');
}
}
//-->
</script>
并在
<form action="registered.php" method="post" name="frmRegister" onsubmit="MM_validateForm('addr1','','R');return document.MM_returnValue" >
当我在 chrome 浏览器上运行它时,我收到一条错误消息,提示警报未定义。
我尝试检查其他答案,但无法使代码正常工作。有人可以帮忙吗?
