// You can also construct a button in the form, and use GetCommand to receive the contents of the cmd attribute.
var table = {
type: 'table',
title: 'position operation',
cols: ['Column1', 'Column2', 'Action'],
rows: [
['abc', 'def', {'type':'button', 'cmd': 'coverAll', 'name': 'close position'}],
]
};
LogStatus('`' + JSON.stringify(table) + '`')
// Or construct a separate button
LogStatus('`' + JSON.stringify({'type':'button', 'cmd': 'coverAll', 'name': 'close position'}) + '`')
// Button styles can be customized (bootstrap's button attributes)
LogStatus('`' + JSON.stringify({'type':'button', 'class': 'btn btn-xs btn-danger', 'cmd': 'coverAll', 'name': 'close position'}) + '`')
Dokumentasi API menunjukkan bahwa menampilkan tabel, string, gambar, grafik, dll di bilah status strategi dicapai dengan memanggil fungsi API:
LogStatus
.Kita juga dapat mengatur tombol interaktif dengan membangun data JSON.
DEMO Kode Sumber:
“
function test1(p) { Log("Calls a custom function with parameters:", p); return p; } function main() { while (true) { var table = { type: 'table', title: 'position operation', cols: ['Column1', 'Column2', 'Action'], rows: [ ['a', '1', { 'type': 'button', // To display a button, you must set the type to button. 'cmd': "CoverAll", // String, sent data, accepted by the GetCommand() function. 'name': 'close position' // The name displayed on the button. }], ['b', '1', { 'type': 'button', 'cmd': 10, // numerical value 'name': 'Send value' }], ['c', '1', { 'type': 'button', 'cmd': _D(), // The function is called for the duration of the strategy run 'name': 'call the function' }], ['d', '1', { 'type': 'button', 'cmd': 'JScode:test1("ceshi")', // String, the JS code to execute. 'name': 'Send JS Code' }] ] }; LogStatus('
+ JSON.stringify(tabel) + ` )
var str_cmd = GetCommand();
if (str_cmd) {
Log("Received Interaction Data str_cmd:", "type:", typeof(str_cmd), "value:", str_cmd);
}
if (str_cmd && str_cmd.split(':', 2)[0] == "JScode") { // Determine if there is a message
var js = str_cmd.split(':', 2)[1]; // Split the returned message string, limit it to two, and assign the element with index 1 to a variable named js.
Log("Execute debugging code:", js); // Output executed code
try { // Abnormal detection
eval(js); // Executes the eval function, which executes the parameters (code) passed in.
} catch (e) { // throw an exception
Log("Exception", e); // Output error messages
}
}
Sleep(500);
}
}
Let's run it. The strategy runs as shown:
![Constructing Interactive Button Functions in the Strategy Status Bar](/upload/asset/28d692a53d0c76776636b.png)
We can trigger the interaction by clicking on the buttons in the table on the status bar. We will click on the "Close Position" and "Send Value" buttons in turn.
When we click on the "Close Position" button, the message will be sent as normal:

Tapi itu tidak bekerja ketika Anda mengklik pada
Send value karena[ 'cmd': 10, // value
Ini adalah 10. Jenis numerik tidak dapat dikirim.https://www.fmz.comFungsi Tombol Interaktif di Bar Status Strategi](/upload/asset/2d8e0f86599f1b82da792544b7b840bc824d4a96.png)
Ini telah dioptimalkan untuk kompatibel dengan nilai numerik, dan mengembalikan string nilai.

Selanjutnya kita klik tombol
Data yang diterima dicetak di log:
Akhirnya, mari kita klik pada
function test1(p) {
Log("Calls a custom function with parameters:", p);
return p;
}
Klik tombol:
Anda dapat melihat bahwa Log ((
Calling fungsi kustom dengan parameter: , p); pernyataan dalam fungsi test1 dijalankan.
