jQuery Validation Plugin verification plug-in manual verification_jquery

jquery.validate is a verification framework under jquery. With the advantages of jquery, we can quickly verify some common inputs, expand our own verification methods, and also have good support for internationalization.
The normal verification mode is as follows:
<form id="ff" action="xxx">
...
<input type="submit" value="提交">
</form>

$('#ff').validate()
As long as you click the submit button, the plug-in will automatically verify.
But sometimes we want to click other buttons to validate the form, and then do the rest based on the validation results of the form.
Looking at the source code, I found that there is a form() method. This method is to perform verification operations, although the literal meaning of the method does not match.
Then we can do this:
var validator;// 申明一個(gè)全局變量
$(function(){
validator = $('#ff').validate();// 這句話會返回一個(gè)對象
})
function add() {
var b = validator.form();// 返回一個(gè)布爾值
if(b){ // 驗(yàn)證成功
// do add...
}
}
<button onclick="add()">保存</button>
If a verification error occurs, an error message will be displayed. If you want to clear the error message, you can call the validator.resetForm(); method
In this way, with the two methods validator.form() and validator.resetForm() we can use the verification plug-in flexibly.

The following points should be noted when processing dates and time in JavaScript: 1. There are many ways to create Date objects. It is recommended to use ISO format strings to ensure compatibility; 2. Get and set time information can be obtained and set methods, and note that the month starts from 0; 3. Manually formatting dates requires strings, and third-party libraries can also be used; 4. It is recommended to use libraries that support time zones, such as Luxon. Mastering these key points can effectively avoid common mistakes.

What is event bubbling and capturing in the DOM?
Jul 02, 2025 am 01:19 AM
Event capture and bubble are two stages of event propagation in DOM. Capture is from the top layer to the target element, and bubble is from the target element to the top layer. 1. Event capture is implemented by setting the useCapture parameter of addEventListener to true; 2. Event bubble is the default behavior, useCapture is set to false or omitted; 3. Event propagation can be used to prevent event propagation; 4. Event bubbling supports event delegation to improve dynamic content processing efficiency; 5. Capture can be used to intercept events in advance, such as logging or error processing. Understanding these two phases helps to accurately control the timing and how JavaScript responds to user operations.
