How to submit bootstrap form

Bootstrap provides a simple way to submit a form: 1. Add an action attribute, specifying a submission URL; 2. Add a method attribute, specifying an HTTP method (usually POST or GET); 3. Add a submission button, usually using the type="submit" attribute.

Bootstrap form submission

Bootstrap provides an easy way to submit forms without writing complex JavaScript code. Here is how to submit a Bootstrap form:

1. Add action attributes

Add an action attribute to the form tag to specify the target URL after the form is submitted.

 <code class="html"><form action="submit.php"></form></code>

2. Add method properties

Add method attribute to the form tag, specifying the HTTP method (usually "POST" or "GET") to be used when submitting the form.

 <code class="html"><form action="submit.php" method="post"></form></code>

3. Submit button

Add a submit button to the form, usually using <button></button> or <input> elements. In the <button></button> element, add type="submit" attribute; in <input> element, add type="submit" and value attributes.

 <code class="html"><button type="submit">提交</button>或<input type="submit" value="提交"></code>

What happens when submitting the form

When the user clicks the Submit button, the following will occur:

1. The browser collects the values ​​of all controls in the form.
2. The browser sends these values ​​to the URL specified in action attribute.
3. The server processes form data, such as saving to a database or sending emails.

Things to note

• Ensure that the target URL can handle form data.
• Use method="post" to submit sensitive data, because the form data requested by the GET is visible in the URL.
• Additional input controls can be included in the form, such as text boxes, check boxes, and drop-down lists.
