Webstrom不能识别${}

【已设置 -> Language & Frameworks -> JavaScript -> 选择EcmaScript 6

function checkRequired(inputArr){
    inputArr.forEach(function(input){
        if(input.value.trim()==="")
        {
            showError(input,'${getKeyword(input)}为必填项')
        }else{
            showSuccess(input);
        }

    })
}
function getKeyword(input){
    return input.placeholder.slice(3);
}

这里识别不了${getKeyword(input)}
