Ajax
is used to perform network tasks on Android. A long-hand Ajax task can be started with any of the four methods:
ajax(Map<String, Object> options)
Accepts a key-value pairing of Ajax Options. For example:
ajax($.map($.entry("context", this), $.entry("url", "http://www.example.com"), $.entry("type", "GET"), $.entry("dataType", "TEXT"), $.entry("success", new Function(){
@Override
public void invoke($ droidQuery, Object... params) {
droidQuery.alert((String) params[0]);
}
})));
ajax(String options)
Accepts a JSON String of Ajax Options. For example:
String data = "{id: 1, text: 'foobar'}";
ajax("{url: 'http://www.example.com', type: 'POST', dataType: 'JSON', data: '" + data +"'}");
ajax(JSONObject options)
Accepts a JSON Object of Ajax Options. For example:
JSONObject json = new JSONObject();
json.put("url", "http://www.example.com");
json.put("type", "DELETE");
json.put("dataType", "XML");
json.put("context", this);
json.put("success", new Function() {
@Override
public void invoke($ droidQuery, Object... params) {
$.alert("Success!");
}
});
ajax(json);
ajax(AjaxOptions options)
Accepts an AjaxOptions Object to configure the request. For example:
ajax(new AjaxOptions().url("http://www.example.com")
.type("GET")
.dataType("Script")
.context(this).success(new Function() {
@Override
public void invoke($ droidQuery, Object... params) {
ScriptResponse response = (ScriptResponse) params[0];
droidQuery.alert(response.output);
}
}).error(new Function() {
@Override
public void invoke($ droidQuery, Object... params) {
Log.e("$", "Could not complete ajax request");
}
});
