将C ++或JS函数写入QML

问题描述

我有一个QML文件，我正在显示我的网络设备的更新。

I have a QML file where i am displaying update of my device of the network.

Text{
    x: 110; y: 84
    text : pIso.gVolt(pIso.gVolt); color : "white"; font.pointSize: 6; textFormat: Text.StyledText


    onTextChanged: {
//here I want to add the code to write update value of device into log file(CSV)
}
}

是否可以使用Java脚本执行此操作？
