In website operation, every aspect of user experience is crucial, even a small failure in captcha submission. If not handled properly, it may make users feel frustrated and even choose to leave.As an experienced website operations expert, I know that AnQiCMS (AnQiCMS) needs to pay attention to every detail while providing efficient and customizable solutions.Today, let's delve into how to provide users with more friendly and guiding error feedback when the captcha submission fails on the AnQiCMS front-end page.
Auto CMS is dedicated to providing secure and efficient content management services in design.The built-in captcha mechanism is an important part of ensuring website security, especially playing a key role in interactive scenarios such as leaving messages and comments./api/captcha) Interacting to achieve image display and ID acquisition.When the user submits the form, the system will compare the verification code entered by the user with the verification code ID stored on the backend.This process may occur in the background, but its results - regardless of success or failure - should be presented to the frontend user in a way that is easy to understand.
Why is friendly error feedback important?
Imagine, the user fills in a long comment or message, looking forward to clicking submit, only to find that the page does not respond, or only pops up a stiff 'Submission failed' prompt.This experience is undoubtedly bad.It not only wastes users' time and energy, but may also lead to negative emotions towards the website and reduce trust.
- Clarify the issue at hand:Tell the user exactly what went wrong instead of vague hints. For example, 'The captcha is incorrect, please try again' is more informative than 'Submission failed'.
- Provide a solution:While pointing out the error, inform the user of what they should do next, such as 'Click the image to refresh the captcha' or 'Please check your input and try again.'
- Reduce user frustration:Clear instructions can effectively reduce negative emotions caused by user operations, encouraging them to continue trying.
- Enhance brand image:Details reveal the truth, a good user experience can make users feel the professionalism and humanization of the website.
Front-end feedback strategy when the security CMS captcha submission fails
The captcha submission mechanism of AnQi CMS usually verifies through an API interface when a user submits a message or comment form.When the captcha verification fails, the backend will return an error message.The front-end page needs to capture this error and present it to the user in a user-friendly manner.tag-/anqiapi-other/167.htmlandtag-/anqiapi-other/158.htmlThe clues provided, front-end interaction usually involves JavaScript processing of API return data.
First, let's take a look back attag-/anqiapi-other/167.htmlThe JavaScript code for loading the captcha image in the middle:
<script>
document.getElementById('get-captcha').addEventListener("click", function (e) {
fetch('/api/captcha')
.then(response => {
return response.json()
})
.then(res => {
document.getElementById('captcha_id').setAttribute("value", res.data.captcha_id)
document.getElementById('get-captcha').setAttribute("src", res.data.captcha)
}).catch(err =>{console.log(err)}) // 这里的err处理是关键
});
document.getElementById('get-captcha').click();
</script>
This code is mainly responsible for fetching and displaying the captcha image, wherecatch(err =>{console.log(err)})is the entry point for capturing network or other request errors. After the user submits the form, if submitted using AJAX (such astag-/anqiapi-other/158.htmlIn comments liking.$.ajaxAs shown in the example), the JSON data returned by the backend will usually contain.code(Status code) andmsg(Error information).
Based on this, we can design the following feedback strategy:
Immediate visual feedback:When the user clicks the submit button, the submit button should first be disabled, and a loading indicator (such as a spinning icon) should be displayed to let the user know that the system is processing the request.This can prevent users from clicking repeatedly and also provides immediate feedback.
Clear error message display:Once we receive the validation failed message from the backend, we need to:
res.msgContains the error message and clearly displays it to the user.**The practice is to set a dedicated area near the captcha input box, or at the top/bottom of the form, to display these errors.This area can be highlighted with prominent colors (such as red).For example, you can add a:
divElement:<div id="captcha-error-message" style="color: red; margin-top: 5px;"></div>Automatically refresh the captcha:The original captcha becomes invalid after a failed submission. Therefore, we need to automatically refresh the captcha image and generate a new one while displaying the error message.
captcha_idand update the imagesrcThis can save users from manually clicking to refresh and improve fluidity.Guide the user to re-enter:After displaying the error message and refreshing the captcha, the user's focus should be guided back to the captcha input box and the previous incorrect input should be cleared.So, the user can directly re-enter a new captcha without any additional operations.
An example of implementing front-end feedback (assuming AJAX submission)
To implement the above strategy, we usually intercept the default form submission behavior, send the form data to the backend via AJAX, and process the JSON data returned by the backend.tag-/anqiapi-other/162.htmlThis mentionsreturn: html|jsonThis indicates that we can configure the form to receive responses in JSON format, which is exactly what AJAX processing requires.
The following is a simplified JavaScript code snippet demonstrating how to combine AJAX submission and friendly error feedback:
// Refresh the captcha function function refreshCaptcha() { fetch('/api/captcha')
.then(response => response.json())
.then(res => {
captchaIdInput.value = res.data.captcha_id;
captchaImage.src = res.data.captcha;
if (captchaTextInput) captchaTextInput.value = ''; // 清空验证码输入框
