You may be able to write it inside your current scope ie.
The following code is working on my PC, it is incrementing the string value “15” to string value “16”:
- Rectangle {
- width: 360
- height: 360
- Text {
- anchors.centerIn: parent
- text: incrementString("15");
- }
- function incrementString(string)
- {
- var stringValue = String(parseInt(string) + 1);
- return stringValue;
- }
- MouseArea {
- anchors.fill: parent
- onClicked: {
- }
- }
- }
