jquery accesses JSON, JS and other files

2. jquery obtains JSON-formatted files directly through the Getjson () function:

   1. First: The contents of the obtained file must conform to the JSON format:

      1. {"Property": "Property value" ....} The format;

   2. Otherwise, this method is not accessible to the content;

   3. The code format is as follows :

      1. $ (function () {$.getjson ("Datagrid_data2.json"),//loaded JSON file, specifying the specific directory function (JSON) {//Execute successful callback function columns = JSON; });});

3. Asynchronously loads the file via jquery's Ajax, GET, Post methods:

   2. The data that is loaded by this asynchronous method may not be in pure JSON format, but can be other formats;

   4. If it is JSON format data, specify datatype: "JSON", you can directly get to the JS object;

   6. If the data is not in JSON format, you can specify datatype: "text", "html" ...

   8. 1. $.ajax ({    url :  "ColumnName.json",// Requested resource     datatype: "Text",             //returned result type: Text     success : function (JSON)  {     //performs a successful callback function Console.info (JSON);         //Console output var arr =  eval ("("  + json +  ")");     //if it is text, convert it to Object init (arr);  
            }); 

   10. $.get ():

       1. Note the order of the parameters passed, the order is not correct, and will fail (can not write some but the order must be)
          

       2. $.get ("Columnname.json",//Access resource {},//passed parameter function (JSON) {///Success callback function var arr = eval ("(" + JSON + ")"); Convert the received parameter to object}, "text"//Return the result type (XML, HTML, script, JSON, text, _default));

   12. $.post ():

       1. Similar to the Get method;
