[英]How to check if the array of objects contains same value for a specific key
我有以下对象数组:
const array = [
{
"id":1,
"environment":"ENV1",
"other_key":"other_value"
},
{
"id":2,
"environment":"ENV1",
"other_key":"other_value_two"
},
{
"id":3,
"environment":"ENV2",
"other_key":"other_value_three"
}
]
现在,如果数组具有不同的环境值,我需要显示警报。 如果所有环境都相同,我不需要显示警报。 在上面的例子中,我需要显示警告警报。
如何检查数组是否包含特定键的不同值或是否具有相同的值?
我认为你可以这样做:
const array = [ { "id":1, "environment":"ENV1", "other_key":"other_value" }, { "id":2, "environment":"ENV1", "other_key":"other_value_two" }, { "id":3, "environment":"ENV2", "other_key":"other_value_three" } ] const everyEnvHasSameValue = array.every( ({other_key}) => other_key === array[0].other_key); // use proper name console.log(everyEnvHasSameValue);
我只想在这里使用过滤器:
const array = [
{
"id":1,
"environment":"ENV1",
"other_key":"other_value"
},
{
"id":2,
"environment":"ENV1",
"other_key":"other_value_two"
},
{
"id":3,
"environment":"ENV1",
"other_key":"other_value_three"
}
]
const el = array.filter(e => e.environment !== array[0].environment)
if(el.length > 0) alert('envs are diff')
