@ -259,6 +259,12 @@ A number box needs to have a min and a max value. To set it up just use:
|
||||
|
||||
`ESPUI.number("Numbertest", &numberCall, ControlColor::Alizarin, 5, 0, 10);`
|
||||
|
||||
Note that HTML number boxes will respect their min and max when the user
|
||||
clicks the up and down arrows, but it is possible on most clients to simply type
|
||||
any number in. As with all user input, numbers should be validated in callback code
|
||||
because all client side checks can be skipped. If any value from the UI might
|
||||
cause a problem, validate it.
|
||||
|
||||
#### Text Input
|
||||
|
||||
|
||||
@ -267,6 +273,17 @@ The textinput works very similar like the number input but with a string. You
|
||||
can enter a String into it and when you are done with your change it is sent to
|
||||
the ESP.
|
||||
|
||||
If you attach a Max control to the text input then a max length will be applied
|
||||
to the control.
|
||||
|
||||
```
|
||||
text = ESPUI.text("Label", callback, ControlColor::Dark, "Initial value");
|
||||
ESPUI.addControl(ControlType::Max, "", "32", ControlColor::None, text);
|
||||
```
|
||||
|
||||
However even with a set maximum length, user input should still be validated
|
||||
because it is easy to bypass client-side checks. Never trust user input.

Initially this function used to send the control element data individually.

sent as one blob at the beginning. Therefore a new type is used as well

JSON describing the controls of the UI, starting from the control at index startidx.

will be sent in order to avoid websocket buffer overflows. The client will acknowledge

receipt of a partial message by requesting the next chunk of UI.
