public sendAndLoad(url:String, target:Object, [method:String]) : Boolean

Posts variables in the my_lv object to the specified URL. The server response is downloaded, parsed as variable data, and the resulting variables are placed in the target object.

Variables are posted in the same manner as LoadVars.send(). Variables are downloaded into target in the same manner as LoadVars.load().

In SWF files running in a version of the player earlier than Flash Player 7, url must be in the same superdomain as the SWF file that is issuing this call. A superdomain is derived by removing the left-most component of a file's URL. For example, a SWF file at www.someDomain.com can load data from sources at store.someDomain.com, because both files are in the same superdomain of someDomain.com.

In SWF files of any version running in Flash Player 7 or later, url must be in exactly the same domain. For example, a SWF file at www.someDomain.com can load data only from sources that are also at www.someDomain.com. If you want to load data from a different domain, you can place a cross-domain policy file on the server hosting the SWF file.

This method is similar to XML.sendAndLoad().

Parameters

url:String - A string; the URL to which to upload variables. If the SWF file issuing this call is running in a web browser, url must be in the same domain as the SWF file.

target:Object - The LoadVars or XML object that receives the downloaded variables.

method:String [optional] - A string; the GET or POST method of the HTTP protocol. The default value is POST.

Returns

Boolean - A Boolean value.

Example

For the following example, add a TextInput instance called name_ti, a TextArea instance called result_ta, and a Button instance called submit_button to the Stage. When the user clicks the Login button instance in the following example, two LoadVars objects are created: send_lv and result_lv. The send_lv object copies the name from the name_ti instance and sends the data to greeting.cfm. The result from this script loads into the result_lv object, and the server response displays in the TextArea instance (result_ta). Add the following ActionScript to Frame 1 of the Timeline:

var submitListener:Object = new Object();
submitListener.click = function(evt:Object) {
    var result_lv:LoadVars = new LoadVars();
    result_lv.onLoad = function(success:Boolean) {
    if (success) {
        result_ta.text = result_lv.welcomeMessage;
    } else {
        result_ta.text = "Error connecting to server.";
    }
    };
    var send_lv:LoadVars = new LoadVars();
    send_lv.name = name_ti.text;
    send_lv.sendAndLoad("http://www.flash-mx.com/mm/greeting.cfm", result_lv, "POST");
};
submit_button.addEventListener("click", submitListener);
