如何设置表单提交中的变量以用于AJAX调用？

Question

I have the below form:

  <form action="test.php" method="POST" onsubmit="loadXMLDoc(this.form); return false;">
  <input class="com" type="text" name="test" />
  </form>

Instead of "this.form", what would need to be in its place so that the text input by the user is passed to loadXMLDoc?

Also: is that the correct syntax to then send this variable data?

function loadXMLDoc($testVariable)

//standard ajax code..

xmlhttp.send("test=" + $testVariable);

Answer 1

该表单可以按名称引用输入元素作为属性。

loadXMLDoc(this.test.value);
