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:
- The browser collects the values ??of all controls in the form.
- The browser sends these values ??to the URL specified in
actionattribute. - 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.
