document.getElementById(wordArray[i]).value = answer[i]   ' '   wordArray[i];

I want to strike through part answer[i], but not wordArray[i]. How should I go about this? Thanks.

CodePudding user response：

Strike though a variable sounds weird, do you mean to strike a text (string)? In that case you have text-decoration: line-through; (see more about text-decoration)

If that's the case you can wrap your variabe into a span tag, i.e.:

'<span >' answer[i] '</span>

.line-through { text-decoration: line-through }
