Plug-in writing mode
var $ = require('common:jquery');
function serverError(opt) {
this.options = $.extend({
dom: null
}, opt || {} );
this.init();
}
serverError.prototype = {
init: function() {
this.errID = this.options.dom + "serverError";
var html = ''
$('#' + this.options.dom).css("position", "relative").append(html);
},

$('#' + this.errID).text(msg).show();
},

}
}
return serverError;
1. Generate random numbers

Math.floor(Math.random()*11) (generate random numbers between 0-10)
// Horizontal screen monitoring
var updateOrientation = function(){
if(window.orientation=='-90' || window.orientation=='90'){
$('.landscape-wrap').removeClass('hide');
console.log('For a better experience, please turn your phone/tablet upside down!');
}else{
} $('.landscape-wrap').addClass('hide');
console.log('portrait screen status');
}
};
window.onorientationchange = updateOrientation;
2. Display the width and height of the monitor var w=window.innerWidth
|| document.documentElement.clientWidth
|| document.body.clientWidth;
var h=window.innerHeight
|| document.documentElement.clientHeight
|| document .body.clientHeight;

screen.availWidth - available screen width
screen.availHeight - available screen height
3. Window calling method
window.open() - open a new window
window.close() - close the current window
window.moveTo() - Move the current window
window.resizeTo() - Adjust the size of the current window
4. Window return
location.hostname returns the domain name of the web host
location.pathname returns the path and file name of the current page
location .port returns the port of the web host (80 or 443)
location.protocol returns the web protocol used (http:// or https://)
4.1 Rounding up and down
Math.ceil() performs rounding up , i.e. it always rounds the value up to the nearest integer;
Math.floor() performs rounding down, i.e. it always rounds the value down to the nearest integer;
Math.round() Performs standard rounding, i.e. it always rounds the value to the nearest integer (this is also the rounding rule we learned in math class). The object behind
Math()
abs(x) returns the absolute value of the number.
acos(x) returns the arc cosine of a number.
asin(x) returns the arcsine of a number.
atan(x) returns the arctangent of x as a value between -PI/2 and PI/2 radians.
atan2(y,x) returns the angle from the x-axis to the point (x,y) (between -PI/2 and PI/2 radians).
ceil(x) rounds up the logarithm.
cos(x) returns the cosine of the number.
exp(x) returns the exponent of e.
floor(x) rounds down the logarithm.
log(x) returns the natural logarithm of a number (base e).
max(x,y) returns the highest value between x and y.
min(x,y) returns the lowest value between x and y.
pow(x,y) returns x raised to the y power.
random() returns a random number between 0 ~ 1.
round(x) rounds the number to the nearest integer.
sin(x) returns the sine of a number.
sqrt(x) returns the square root of a number.
tan(x) returns the tangent of the angle.
toSource() returns the source code of the object.
valueOf() returns the original value of the Math object.
5. Object-oriented

Requirements of object-oriented languages
An object-oriented language needs to provide developers with four basic capabilities:
Encapsulation - the ability to store related information (whether data or methods) in objects
Aggregation - The ability to store one object within another object
Inheritance - the ability to derive the properties and methods of a class from another class (or classes)
Polymorphism - the ability to write functions or methods that can be run in multiple ways
prototype (create a new method through an existing method)
When calling the apply() method, the first parameter is still obj, which means that the value of this keyword in the sayColor() function should be given as obj.
The second parameter is an array composed of two strings,
matches the parameters sPrefix and sSuffix in the sayColor() function. When calling the call() method, the first parameter is obj,
indicating that it should be assigned to the sayColor() function The value of this keyword in is obj. The second and third parameters are strings.
6 PHP
PHP global keyword
The global keyword is used to access global variables within a function.
PHP static keyword
Normally, when a function completes/executes, all variables are deleted.
PHP echo and print statements
The difference between echo and print:
echo - can output more than one string
print - can only output one string and always returns 1
PHP var_dump() will return the data type of the variable Sum value:
PHP var_dump() will return the data type and value of the variable:
PHP strlen() function
The strlen() function returns the length of the string, in characters.
PHP strpos() function
The strpos() function is used to retrieve specified characters or text within a string.量 Set the PHP constant p If you need to set the constant, use the define () function-it uses three parameters:
The first parameter defines the constant name
The second parameter defines the value of the third parameter. Whether the name is case-sensitive. The default is false.
PHP count() function
Gets the length of an array
The count() function is used to return the length of an array (number of elements):
PHP - Sorting function for arrays
sort() - Sorts an array in ascending order
rsort() - Following Sort an array in ascending order
asort() - Sort an associative array in ascending order based on value
ksort() - Sort an associative array in ascending order based on key
arsort() - Sort an associative array in descending order based on value
krsort() - Sorts an associative array in descending order based on key
PHP Global Variables - Superglobal Variables
Many predefined variables in PHP are "superglobal", meaning they are in the entire scope of a script are available.
You can access them within a function or method without executing global $variable;.
These superglobal variables are:
$GLOBALS
$_SERVER
$_REQUEST
$_POST
$_GET
$_FILES
$_ENV
$_COOKIE
$_SESSION
PHP Date() function
PHP Date() function formats the timestamp into a more readable date and time. E grammar
Date (Format, Timestamp)
php mktime ()
$ d = mktime (9, 12, 31, 6, 10, 2015); time,now)
HP include and require statements
With the include or require statement, the contents of a PHP file can be inserted into another PHP file (before the server executes it).
The include and require statements are identical, except for error handling:
require will generate a fatal error (E_COMPILE_ERROR) and stop the script
include will only generate a warning (E_WARNING), and the script will continue
PHP readfile() function
readfile() function Read the file and write it to the output buffer.

The above has introduced JS PHP intrusion, including aspects of it. I hope it will be helpful to friends who are interested in PHP tutorials.
