I have global variable of type boolean isButtonEnabled= false. I would like to make this button enabled when atleast on cell got filled in the excel grid. I have 4 columns and currently I defined renderer for each column to check its null or emptiness and make the button disabled if its empty.
public isButtonEnabled = false; // global variable.
public myCustomTextRenderer(instance, td, row, col, prop, value, cellProperties) {
Handsontable.renderers.TextRenderer.apply(this, arguments);
if( isNullOrUndefined(value) || value.length === 0 ) {
// make my button disabled
} else {
//make my button enabled if the value is not null or not empty
//trying to access global variable here, but not working.
this.isButtonEnabled = true// this is referencing to this funciton context
// I used window.isButtonEnabled also // but not working.
}
retrun td;
}
