SUI.xhr
Holds a set of xhr related functions.
Defined in: xhr.js| Attr. | Type | Name / Description |
|---|---|---|
| public |
doGet(url, data, callback) Execute a get request to an http server and supply a callback function to deal with the response. |
|
| public |
doPost(url, data, callback) Execute a post request to an http server and supply a callback function to deal with the response. |
|
| public | Object |
queryString(data) Convert a javascript object to an url query string. The data will be url-encoded. The function does not support rescursive structures (no inner objects) but it supports 1D array values for the members of the argument object. Note that this function is designed to work with PHP and that arrays will be converted to the "name[]" syntax that (afaik) only PHP supports. For example: { a: "V&D", b: [1, 2] } will be translated to "a=V%26D&b[]=1&b[]=2". |
| public | Object[] |
Convert tabelized data to an array of objects. When sending a json string containing an huge array of objects you might want to consider to send the data in a table format: nn array of values only in which the first row defines the field names of the data that follows. For example:
[
{ id: 1, name: "Jan" },
{ id: 2, name: "Piet" },
{ id: 3, name: "Klaas" },
...
]
Can also be presended as: [ ["id", "name"], [1, "Jan"], [2, "Piet"], [3, "Klaas"], ... ] This function converts the latter to the former. |
