本文介绍了如何使用JavaScript来实现表单的自动提交。通常情况下，表单提交是通过用户点击提交按钮来触发的，但在某些场景下可能需要通过编程方式来实现这一功能。文章提供了具体的代码示例，包括如何通过JavaScript获取表单对象并调用submit()方法。
--How to Submit a Form Using JavaScript
Generally, a form is submitted when the user presses a submit button. However, sometimes, you may need to submit the form programmatically using JavaScript.
JavaScript provides the form object that contains the submit() method. Use the ‘id’ of the form to get the form object.
For example, if the name of your form is ‘myform’, the JavaScript code for the submit call is:
document.forms["myform"].submit(); |
But, how to identify a form? Give an id attribute in the form
tag
<form id='myform' action='formmail.pl'> |
Here is the code to submit a form when a hyperlink is clicked:
<form name="myform" action="handle-data.php"> |
Search: <input type='text' name='query' /> |
<a href="javascript:
submitform()">Search</a> |
</form> |
<script type="text/javascript"> |
function submitform() |
{ |
document.myform.submit(); |
} |
</script> |
<html><head>url</head>
<script
src="http://code.jquery.com/jquery-latest.min.js"></script>
<body>
<form
name="testForm" id="testForm"
mothod="GET">
<input
type="text" name="test1" id="order"
value="order">
<input
type="text" name="test2"
value="get2">
<input
type="submit" name="Submit" value="yes"
>
<a
href="javascript:
submitform();">submit</a>
</form>
<script
type="text/javascript">
function
submitform()
{
//
document.forms['testForm'].submit();
$('testForm').submit(); //here
is id="testForm"
}
function
$(xxx)
{
return
document.getElementByIdx_x_x_x(xxx);
}
</script>
</body>
</html>
