我知道您不能在<form>like中使用 onLoad 属性<form id"form" onload="javascript:test()">，您只能在<body>

我的问题是，是否有任何属性可以在表单加载时调用函数，或者是否有不同的方法来执行此操作？

编辑：

就像这样

<form jwcid="form">
<script>
function checkForChange() {
var approvalStatus = document.getElementById('licensingStatus').value;
if(approvalStatus == "Pass"){
    document.getElementById('licensingApprovalDate').setAttribute("validators", "validators:maxDateToday,required");
} else {
    document.getElementById('licensingApprovalDate').setAttribute("validators", "validators:maxDateToday");
}   
}
</script>
.....

表单不使用外部数据来构建它们（主体可以加载图像，iframe 可以加载外部文档等）。

所以：

</form>
<script> /* The form has loaded. Do your stuff */ </script>

What do you mean with "form is loaded"? I think you mean "when the form is submited". The attribute is "onsubmit": <form id="form" onsubmit="javascript:test()">

Your funktion has to return either true or false whether the form shall be submitted or not.
