jQuery validation validate only on form submit
Article Introduction：When using the jQuery validation plugin, you may experience verification stuttering when typing in the input field. This is most common when using custom verification rules triggering ajax request to verify user input (for example, checking if the user's email is unique in the database). The lag experience was awful. To eliminate continuous validation checks, add the following parameters to the form validation function:
onkeyup: false,
onclick: false,
onfocusout: false,
Therefore, your verification function might look like this:
$("#form").validate({
onkeyup: false

Article Introduction：Function or operator overloading allows the same name to perform different operations according to different parameters, improving code readability and flexibility. 1. Function overloading refers to the multi-version definition of functions with the same name through the number, type or order of parameters, and the return value cannot be used as the only distinguishing standard; 2. Operator overload implements specific methods (such as C operator) in custom classes, making operators suitable for custom types; 3. Supported languages ??include C (full support), Java (only function overload), and Python (flexible support), while JavaScript and Go do not support them; 4. Pay attention to maintaining logical intuition when using them to avoid abuse and causing maintenance difficulties.

What are some advanced uses of Python's functools.wraps in writing decorators?
Article Introduction：functools.wraps not only retains function names and document strings in Python decorators, but also supports retaining function signatures to improve tool support, correctly track original functions in multi-layer decorators, simplify debugging processes, and allow custom attribute copying. 1. Use wraps to preserve the complete function signature, so that the IDE, linters and document generation tools can more accurately identify the decorated functions; 2. When stacking multiple decorators, the original functions can still be correctly identified through __name__, which facilitates logging and debugging; 3. Display the correct function name and module information during debugging to avoid the difficulty of error tracking; 4. You can customize the attributes to be copied through the assigned parameter, such as copying only __name__

Intelligent String Abbreviation
Article Introduction：Core points
The abbreviate() function in JavaScript can intelligently shorten the string to the specified maximum length, ensuring that it does not break in the middle of the word, and removing unnecessary spaces.
This function takes three parameters: the original input string, the maximum output length, and an optional suffix, added to the end of the abbreviation string. If the suffix is ??not defined, the default is "...", indicating the abbreviation.
This function can be used in any scenario where string lengths need to be limited, such as processing form input, creating custom tooltips, displaying mail topics in web-based email lists, or preprocessing data to be sent through Ajax.
The effectiveness of this function is that it can split the input string into a single word,
