jquery serialization Form

I. jquery form serialization 1, serialize ()

Description: Serializes the contents of the form to a string that is used for AJAX requests.

Format: var data = $ (form). Serialize ();
Function: Serializes the contents of the form into a single string.

2.serializeArray ()

Description: Serializes a FORM element (similar to the '. Serialize () ' method) to return the JSON data structure.

Note that this method returns a JSON object rather than a JSON string. You need to use a plug-in or a third-party library for string manipulation.

Format: var jsondata = $ (form). Serializearray ();

Function: serializes a page form into a JSON-structured object. Note Not a JSON string

For example, [{"Name": "Lihui", "Age": "20"},{...}] get data for Jsondata[0].name

Both of these methods can set the data parameter to $ (form) When submitting form data using AJAX. Serialize () or $ (form). Serializearray ().

$(function () {            $("#ajaxBtn"). Click (function () {                varPARAMS1 = $ ("#myform"). Serialize ();//name=zhangsan&sex=1&age=20                varPARAMS2 = $ ("#myform"). Serializearray ();//[Object,object, Object]$.ajax ({type:post, url:RegisterAction.action, DATA:PARAMS1, Success:function(msg) {alert (msg);            }                 }); })        })
