The serialize () method creates a URL encoded text string by serializing the form value. You can select one or more form elements (such as input and/or text boxes) or Form elements. Serialized values can be used in URL query strings when an Ajax request is generated. For example, when Ajax is used, it is often necessary to assemble the input data in the form of 'name = Xiaoming & sex = 1'. The serialize method of jquery can be used to complete this work easily.
Serializearray () serializes form elements
(Similar to the '. serialize ()' method. This method returns a JSON object instead of a JSON string. You need to use plug-ins or third-party libraries for string-based operations.
