This article mainly introduces you to the built-in functions of angularjs, as well as many functions supported by angularjs. Next, let us read this article together

Let’s introduce the built-in functions of angularjs at the beginning:

angular.lowercase: Convert the string to lowercase
##angular.uppercase: Convert the string to uppercase
##angular
.forEach(obj, iterator, [context]) : Traverse a collection of objects. This function includes three parameters. The first parameter represents the object or array to be traversed, the second parameter is a function, and the third object is the current context (this);
```
var values = {name: 'misko', gender: 'male'};
var log = [];
angular.forEach(values, function(value, key) {
  this.push(key + ': ' + value);
}, log);
expect(log).toEqual(['name: misko', 'gender: male']);
```
angular.isUndefined(value); Determine whether value is undefined
#angular. isObject(value); Determine whether value is an object, excluding null
##angular.isString(value ); Determine whether value is of type String
##angular.isNumber(value); Determine whether value is of type Number
##angular.isDate (value); Determine whether value is of Date type
##angular.isArray(value); Determine whether value is an array
##angular
.isFunction(value); Determine whether value is a function type
.isElement(value); Determine whether value is a DOM element, including JQuery encapsulated DOM##
angular.equals(o1, o2); Determine whether two objects are equal

If one of the following conditions is met, they are considered two objects equal.

## o1===o2 returns true
All attributes of o1 and o2 are equal through angular.equals comparison
o1, o2 are both NAN
Two identical regular expressions (/abc/=/abc/) return false in JavaScript and true in angular

13.angular.toJson(obj, pretty); Convert the object to json, obj: the object that needs to be converted, pretty: true or a number, true means retaining spaces and newlines in the object attribute value, set to one Numbers indicate removing spaces and newlines. The default value is 2, which removes spaces and newlines.

##14.angular.fromJson (json);Convert a json string into an object or object array.

15.angular.element(element);Wrap a native DOM or HTML string into a JQuery object.

angularjs has a built-in mini version of JQuery, JQlite(If you want to see more, go to the PHP Chinese website AngularJS Development ManualLearning)

supports the following functions:

##addClass()
#after() 
##append
()
attr
() - Does not support functions as parameters
bind
() - Does not support namespaces, selectors or eventData
() - Does not support selectors
##clone
()

contents

css() - Only retrieves inline-styles, does not call getComputedStyle()
data()
detach()
empty()
eq()
find() - Limited to lookups by tag name
hasClass()
html()
next() - Does not support selectors
on() - Does not support namespaces, selectors or eventData
off() - Does not support namespaces or selectors
one() - Does not support namespaces or selectors
parent() - Does not support selectors
prepend()
prop()
##ready()
remove()
##removeAttr()
removeClass()
removeData()
##replaceWith
()
text

toggleClass
()
()- Passes a dummy event object to handlers.
()- Does not support namespaces
##val
()

wrap
()
