How to solve the javascript json garbled problem?

The use of javascript json (and the resolution of Chinese garbled code)

For js using json, first go to the official website to copy the json.js file, address http://www.json.org/js.html

Then introduce it on the page and use it:

To test whether it works, you can write a jsp page, and then add a method to the button to pop up the processed json string.

For Chinese garbled code, change the coding mode to: GB2312.

You can change it directly on the page or when response returns.

Changes to the page:

Java code response returns the modified method:

Response.setHeader ("Cache-Control", "no-cache"); response.setContentType ("text/json;charset=gb2312")

Insert title here button {margin:4px; cursor:pointer;} input {margin:4px; color:blue;} json / # button3 $("# button3") .click (function () {/ json object converted to j string-- toJSONString () / / string converted to json object-- eval ('('+ str +')') / / take the value point of an attribute in the json object (for example, myObject.bindings [0] .time) var myJSONObject = {"bindings": [{"nnn": "Spring", "time": "Mark", "add": "Beijing"}, {"ircEvent": "good", "method": "method", "regex": "Shanghai"}]} Alert ("json object takes attribute value\ n" + myJSONObject.bindings [0] .nnn); / / json object conversion to json string method: var myJSONtext=myJSONObject.toJSONString (); alert ("json object to string, toJSONString\ n" + myJSONtext); var myJSONtext2=JSON.stringify (myJSONObject); alert ("json object is converted to a string, using the global built-in object JSON.stringify\ n" + myJSONtext2) / / json string conversion to json object methods: var myJSONObject2 = eval ('('+ myJSONtext +')'); var myJSONObject3=myJSONtext.parseJSON (); var myJSONObject4=JSON.parse (myJSONtext); alert ("string conversion to json object, using eval\ n" + myJSONObject2.bindings [0] .time); alert ("string conversion to json object, using parseJSON\ n" + myJSONObject3.bindings [0] .add) Alert ("convert strings to json objects, using the global built-in object JSON.parse\ n" + myJSONObject4.bindings [0] .nnn); /}) Thank you for your reading, the above is the content of "how to solve the javascript json garbled problem", after the study of this article, I believe you have a deeper understanding of how to solve the javascript json garbled problem, and the specific use needs to be verified in practice.
