You can use any operators from the list! && || === == !== != > >= < <= ( )
It works the same as if operator from JavaScript.
conditionHandler([1]) // 1 === 1
conditionHandler([1, '&&', 2]) // 1 && 2 === 2
conditionHandler([1, '&&', 0]) // 1 && 0 === 0
conditionHandler([1, '||', 0]) // 1 || 0 === 1
conditionHandler(['!', 1, '||', 0]) // !1 || 0 === 0
conditionHandler([1, '>', 2]) // 1 > 2 === false
conditionHandler([2, '>=', 1]) // 2 >= 1 === trueYou can use a plugin to handle non-operator argument.
const obj = {
test1: true,
test2: false,
test: {
field1: 1,
field2: 0
}
}
function plugin (condition) {
if (typeof condition === 'string') {
const fields = condition.split('.')
condition = obj
for (let i = 0; i < fields.length; i++) {
condition = condition[fields[i]]
}
}
return condition
}
conditionHandler(['test1', '&&', 'test.field2'], plugin)
// obj.test1 && obj.test.field2 === 0Issues
