This article will explain in detail how Json extends jQuery. The editor thinks it is very practical, so I share it for you as a reference. I hope you can get something after reading this article.

In the past, Json, which is used to extending Jquery, is very convenient to deal with json data in ajax development; in jQuery, it only provides a simple jQuery.getJSON () method, but does not provide jQuery's own conversion of json data, and it is easier to convert json strings into javascript data objects by using the eval () function, but it is more difficult to convert javascript data types into json strings.

Use prototype.js and jQuery when.

Extend the Json code for Jquery:

/ / expand jQuery's conversion of json strings to jQuery.extend ({/ * @ see converts json strings to objects * @ paramjson strings * @ return returns objects such as object,array,string * / evalJSON:function (strJson) {returneval ("(" + strJson+ ")");}}) JQuery.extend ({/ * @ see converts javascript data type to json string * @ param object to be converted. Support object,array,string,function,number,boolean,regexp*@return to return json string * / Json how to extend jQuery toJSON:function (object) {vartype=typeofobject; if ('object'==type) {if (Array==object.constructor) type='array'; elseif (RegExp==object.constructor) type='regexp'; elsetype='object' } switch (type) {case'undefined': case'unknown': return; break; case'function': case'boolean': case'regexp': returnobject.toString (); break; case'number': returnisFinite (object)? object.toString (): 'null'; break Case'string': return' "'+ object.replace (/ (\ |") / g, "\ $1").
