This article will explain in detail what the jQuery.param description is. The editor thinks it is very practical, so I share it with you as a reference. I hope you can get something after reading this article.

JQuery.param ()

Description: creates an array or object serialized string for an URL address query string or Ajax request.

Query.param (obj)

Obj

Type: Array, Object

An object used for arrays or serialization.

JQuery.param (obj, traditional)

Obj

Type: Array, Object

An object used for arrays or serialization.

Traditional

Type: Boolean

A Boolean value indicating whether the traditional "shallow" serialization has been performed.

This function converts the value of the form element to a serialized string (see .serialize () for more details).

In jQuery 1.3, the return value of this function is used instead of the function as a string.

In jQuery 1.4, the $.param () method serializes objects deeply recursively to meet the needs of modern scripting languages and frameworks, such as PHP and Ruby on Rails. You can abolish this global function by setting jQuery.ajaxSettings.traditional = true;.

If the object passed is an array, it must be an array of objects in the same format as returned by .serializeArray ():

[{name: "first", value: "Rick"}

{name: "last", value: "Astley"}

{name: "job", value: "Rock Star"}]

Note: because some frameworks have limited ability to parse serialized numbers, we should be careful not to pass an array containing objects or other arrays nested within an array when passing obj parameters.

Note: since there is currently no unified specification for serialized strings, this method cannot encode complex data structures to support all languages. Until then, the $. Param method will remain in its current form.

This is the end of this article on "what jQuery.param description is". I hope the above content can be helpful to you, so that you can learn more knowledge. if you think the article is good, please share it for more people to see.
