JS是一種腳本語言，可用于提交表單數(shù)據(jù)。在JS中，表單數(shù)據(jù)可以通過form對象進行提交。以下是一個使用JS提交表單數(shù)據(jù)的示例：

<form id="myForm">
<input type="text" name="username">
<input type="password" name="password">
<input type="button" value="Submit" onclick="submitForm()">
</form>
<script>
function submitForm() {
var form = document.getElementById("myForm");
var username = form.elements["username"].value;
var password = form.elements["password"].value;
var xhr = new XMLHttpRequest();
xhr.open("POST", "/submit-form", true);
xhr.setRequestHeader("Content-Type", "application/json;charset=UTF-8");
xhr.send(JSON.stringify({username: username, password: password}));
}
</script>

JQuery是一個流行的JavaScript庫，提供了一些方便的功能。其中包括提交表單數(shù)據(jù)的功能。以下是一個使用JQuery提交表單數(shù)據(jù)的示例：

<form id="myForm">
<input type="text" name="username">
<input type="password" name="password">
<input type="button" value="Submit" id="submitBtn">
</form>
<script src="https://code.jquery.com/jquery-3.5.1.min.js"></script>
<script>
$(document).ready(function() {
$("#submitBtn").click(function() {
var username = $("input[name='username']").val();
var password = $("input[name='password']").val();
$.ajax({
url: "/submit-form",
type: "POST",
contentType: "application/json;charset=UTF-8",
data: JSON.stringify({username: username, password: password}),
success: function(result) {
console.log(result);
},
error: function(error) {
console.log(error);
}
});
});
});
</script>
