Article Introduction：Common input fields for web forms include text, password, email, number, date, radio boxes, check boxes, file upload, submit buttons and reset buttons. 1. Text input (text) is used to freely enter text content, requiring additional verification; 2. Password input (password) hides user input and is often used with confirmation of passwords; 3. Email input (email) automatically checks the format, mobile adaptation optimization; 4. Number input (number) limits input to numbers and supports setting range and step size; 5. Date selection (date) provides calendar controls to improve experience, but compatibility needs to be considered; 6. Radio box (radio) is used for multi-option radio, and the name attribute must be consistent; 7. Checkbox (checkbox) is used for multiple

Article Introduction：The most direct way to set the default value of the form input box is to use the HTML value attribute. The value attribute is used to specify the initial value of the form element, such as:. Common elements that support this attribute include text input boxes, password boxes, radio buttons, check boxes (need to be selected by default with checked settings), submit buttons, etc. Correct usage methods include setting strings for text input, setting legal values for numeric input, and transmitting hidden fields. Notes include: avoid unescaped special characters and elements with selected instead of value, and default values should be written in the tag content. Rational use of value can improve user experience and reduce input burden.

Article Introduction：When building a web form, you should select the appropriate input element according to the required data type. 1. Text input is used for short text such as name or email, and is used with placeholders, maximum character restrictions and labels; 2. Password field hides user input, requires pairing verification and prompts for requirements; 3. Radio buttons are used to select one of multiple options, and share name attributes; 4. Check boxes allow multiple selections, suitable for boolean values ??or function selection; 5. The drop-down menu saves space and is suitable for known option lists; 6. Multi-line text boxes are used for long content input, supporting line breaks. Rationally combining these elements can improve form functionality and user experience.

Article Introduction：The FormData object of JavaScript provides a convenient way to process the HTML form data, especially when using Ajax or fetch to send data to the server. The New FormData () constructor creates a new FormData instance. You can pass the HTML table element directly as the parameter to New FormData ().

Article Introduction：To style the different states of form input (such as selected, invalid or focused), the CSS pseudo-class should be used. 1. Use the checked pseudo-class to set styles for selected check boxes or radio buttons; 2. Use the:invalid pseudo-class to set styles for fields that have not passed the verification, combined with: user-invalid can be applied after user interaction; 3. Use the:focus and:hover pseudo-classes to enhance availability and accessibility; 4. Multiple pseudo-classes can be combined to implement multi-state style design, such as matching invalid and focused states at the same time. These methods can achieve dynamic style changes without JavaScript.

Article Introduction：Use the name attribute to define the field name when the form is submitted, and the server identifies the data type by this name. For example, name="email" will send user input as an email address. Correct usage methods include: 1. Use meaningful names such as username; 2. Avoid using spaces and special characters with first_name; 3. Keep the names of multiple forms consistent; 4. Share the names of related check boxes and add square brackets such as interests[]. Different input types handle differently. Radio buttons need to share names to ensure mutually exclusive selection. Different names should be used if the check box is independent. Common errors include missing name attributes, unrelated fields duplicate names, mismatch of front and back end names, etc., which may cause data to be located.

Use: required pseudo-class to identify required items, usually combining border color and red asterisk prompts, and it is recommended to enhance accessibility with text or icons; 4.

Article Introduction：There are three key points to be mastered when processing Vue forms: 1. Use v-model to achieve two-way binding and synchronize form data; 2. Implement verification logic to ensure input compliance; 3. Control the submission behavior and process requests and status feedback. In Vue, form elements such as input boxes, check boxes, etc. can be bound to data attributes through v-model, such as automatically synchronizing user input; for multiple selection scenarios of check boxes, the binding field should be initialized into an array to correctly store multiple selected values. Form verification can be implemented through custom functions or third-party libraries. Common practices include checking whether the field is empty, using a regular verification format, and displaying prompt information when errors are wrong; for example, writing a validateForm method to return the error message object of each field. You should use it when submitting

Article Introduction：The core method for correctly associating and input boxes is to use the for attribute matching ids to ensure that the screen reader accurately recognizes and improves the accessibility experience. 1. When using the for and id attributes, the values ??must be exactly the same; 2. You can wrap them directly, but problems are prone to occur when the structure is complex; 3. Check boxes and radio buttons should also be added to enhance click areas and accessibility; 4. It is not recommended to rely solely on aria-label or aria-labeledby instead of native tag association methods.

Use appropriate form elements to improve the interactive experience and assist the browser to identify the input type, such as inputtext for text, inputpassword for password, radio for single choice, checkbox for multiple choice, and select for pull-down option; 2. Use HTML5 built-in verification function to reduce JavaScript workload, including required attribute, type=email/url automatic format verification, and min/max/pattern restriction input; 3. Back-end verification cannot be omitted, and it is necessary to check whether the field is empty, verification format, filter sensitive content, and limit input length
