问题
I'm trying to retrieve a variable from an object.
cell: (row: any) => `${row.testcolumn}`
My only issue is that I don't know what 'testcolumn' is ahead of time as I'm doing this dynamically. I'm not sure what to do, and the nested template string strategy I'm attempting will not compile.
cell: (row: any) => `${row.(`${varString}`)}`
I've also tried just using the variable name instead of nesting a template string, but that just looks for the varString value in the object, which doesn't exist. Is there any way I can use a nested literal to substitute the string value into the template literal and it still look for row.testcolumn instead of row.varString?
回答1:
It is same for template literals as for regular JS. Object properties can be retrieved dynamically with bracket notation, row[varString].
It will be:
cell: (row: any) => `${row[varString]}`
