With the continuous development of Internet technology, website form design is becoming more and more important. Forms are the main way for users to submit information to the website, so it is important to design forms that are easy to use and beautiful. How to improve the efficiency of form design so that developers can quickly design and modify website forms?
jQuery is a popular JavaScript library that is widely used by developers around the world. The jQuery form designer is a component based on the jQuery library. Developers can directly use this component to design and generate website forms to improve efficiency.
Next, let’s discuss the steps and methods of using jQuery form designer to implement form design.
Step 1: Introduce jQuery library and form designer plug-in
First, we need to introduce jQuery library and form designer plug-in into the website. You can download the jQuery library from the jQuery official website or introduce it through CDN.
Then, after introducing the jQuery library, you need to download the jQuery form designer plug-in, which can be downloaded on GitHub.
Step 2: Add the form designer to the web page
When adding the form designer to the web page, you need to move the HTML form code to the form designer first. The code is as follows:
<div></div>
Then, add the form designer code in the JavaScript file, as follows:
$('#formbuilder').formBuilder({ formData: formData, onSave: function() { var formData = $('#formbuilder').formBuilder('getData'); var jsonData = JSON.stringify(formData); $('#myform').attr('data-form', jsonData); } });
Here, the formData
variable represents the initialization data of the form, ## The #onSave function is used to save form data.
getDataThe function can get the data of the form designer. Save the form data in an HTML file in
JSON format.
AJAX technology to send the form data to the server. The code is as follows:
$('#myform').submit(function(e) { e.preventDefault(); var jsonData = $('#myform').attr('data-form'); $.ajax({ url: 'form.php', method: 'POST', data: { formdata: jsonData }, success: function(response) { alert(response); } }); });Here, we use the
preventDefault function to prevent the form from submitting by default. Then use
AJAX technology to send the form data to the server through the POST method.
AJAX technology.
