JavaScript Json2 using methods _javascript Tips

Copy Code code as follows:

<script type= "Text/javascript" src= "Json2.js" ></script>
<script>
Declaring JSON data structures directly
var myjsonobject = {"Bindings": [
{"Ircevent": "Privmsg", "Method": "Newuri", "regex": "^http://.*"},
{"Ircevent": "Privmsg", "Method": "Deleteuri", "regex": "^delete.*"},
{"Ircevent": "Privmsg", "Method": "Randomuri", "regex": "^random.*"}
]
};
Declare a string to compare the difference between JSON text and our normal text
var normalstring= ' [{persons:[{name: "Jordan", Sex: "M", Age: "{"}, {name: "Bryant", Sex: "M", Age: "A"}, {name: "McGrady", Sex: "M", Age: "27"}]}] ';
var jsontext= ' [{persons ']: [{' Name ': ' Jordan ', ' sex ': ' m ', ' Age ': '} ', {' name ': ' Bryant ', ' sex ': ' m ', ' Age ': ' '}, {' Name ":" McGrady "," Sex ":" M "," Age ":" 27 "}]}] ';

Call the Eval function into a JSON object,
var Mye = eval (normalstring);
Document.writeln (Mye ' <br><br> ');
Convert a JSON object to a string
var text = json.stringify (Mye);
Compare the converted JSON text to the declared text difference
Document.writeln (' converted JSON text: ' text ' <br><br> declared JSON-formatted text ' Jsontext ' <br><br> declared plain text ' Normalstring ' <br><br> ');

It's better to use JSON parsing when security is more important. JSON parsing only recognizes JSON text and it is more secure, and the following call JSON's parse function generates a JSON data structure for text conversion
var myData = Json.parse (Jsontext);

Document.writeln (myData ' <br><br> ');

The following is a check on the JSON object's additions and deletions

Declaring a JSON object

var jsonobj2={persons:[{name: "Jordan", Sex: "M", Age: "N"}, {name: "Bryant", Sex: "M", Age: "A"}, {name: "McGrady", Sex: "M ", Age:" 27 "}]};

var persons=jsonobj2.persons;
var str= "";

var person={name: "Yaoming", Sex: "M", Age: "26"};
The following is the operation of the JSON object, which removes the annotation to view the results of the operation
JsonObj2.persons.push (person);//array last add a record
JsonObj2.persons.pop ()//Delete last item
JsonObj2.persons.shift ();//Delete first item
JsonObj2.persons.unshift (person);//array front plus a record as long as the appropriate JavaScript method can be used in the JSON object array! So there is another way to splice () CRUD Operations! Delete
JsonObj2.persons.splice (0,2)//start position, delete number
Replace do not delete
var self={name: "Tom", Sex: "M", Age: "24"};
var brother={name: "Mike", Sex: "M", Age: "29"};
JsonObj2.persons.splice (1,0,self,brother,self);//start position, delete number, insert Object
Replace and delete
JsonObj2.persons.splice (0,1,self,brother);//start position, delete number, insert Object

for (Var i=0;i<persons.length;i) {var cur_person=persons[i]; Str =cur_person.name "' Sex are ' cur_person.sex" and age I S "Cur_person.age" <br><br> ";}
Document.writeln (str);
Convert to JSON text
var myjsonobj = json.stringify (JSONOBJ2);
Document.writeln (Myjsonobj);
</script>
