Example introduction to the difference between jquery's trigger and triggerHandler
This article mainly introduces the difference between jquery's trigger and triggerHandler. Friends in need can refer to
trigger and triggerHandler both simulate event. Use a specific case to describe the difference
The code is as follows:
<html lang="en">
<head>
<meta charset="utf-8">
<title>test</title>
<script src="http://code.jquery.com/jquery-1.10.2.js"></script>
</head>
<body>
<input type="checkbox" />
<input type="text" id="test"/>
<input type="button" value="button" id="bnt"
onclick
="bntClick()"/>
</body>
<script>
$(
document
).ready(function() {
$("input[type='checkbox']").bind("click",function(){
$("#test").val("www.baidu.com");
});
});
function bntClick(){
$("input[type='checkbox']").trigger("click");
}
</script>
</html>When the checkbox is clicked, the checkbox is checked and input[type='text'] is assigned the value www.baidu. com
When input[type='button'] is clicked, the same thing as clicking checkbox will happen.
When the trigger is replaced with triggerHandler, when input[type='button'] is clicked, only input[type='text'] is assigned a value without checking the checkbox
triggerHandler prevents the default behavior of the element bound to the event

Concept of c language function
Apr 03, 2025 pm 10:09 PM
C language functions are reusable code blocks. They receive input, perform operations, and return results, which modularly improves reusability and reduces complexity. The internal mechanism of the function includes parameter passing, function execution, and return values. The entire process involves optimization such as function inline. A good function is written following the principle of single responsibility, small number of parameters, naming specifications, and error handling. Pointers combined with functions can achieve more powerful functions, such as modifying external variable values. Function pointers pass functions as parameters or store addresses, and are used to implement dynamic calls to functions. Understanding function features and techniques is the key to writing efficient, maintainable, and easy to understand C programs.
The difference between H5 and mini-programs and APPs
Apr 06, 2025 am 10:42 AM
H5. The main difference between mini programs and APP is: technical architecture: H5 is based on web technology, and mini programs and APP are independent applications. Experience and functions: H5 is light and easy to use, with limited functions; mini programs are lightweight and have good interactiveness; APPs are powerful and have smooth experience. Compatibility: H5 is cross-platform compatible, applets and APPs are restricted by the platform. Development cost: H5 has low development cost, medium mini programs, and highest APP. Applicable scenarios: H5 is suitable for information display, applets are suitable for lightweight applications, and APPs are suitable for complex functions.

Where is the C language function library? How to add the C language function library?
Apr 03, 2025 pm 11:39 PM
The C language function library is a toolbox containing various functions, which are organized in different library files. Adding a library requires specifying it through the compiler's command line options, for example, the GCC compiler uses the -l option followed by the abbreviation of the library name. If the library file is not under the default search path, you need to use the -L option to specify the library file path. Library can be divided into static libraries and dynamic libraries. Static libraries are directly linked to the program at compile time, while dynamic libraries are loaded at runtime.
