How to break out from foreach loop in javascript
提问by Sahil
I am newbie in Javascrript. I have a variable having following details:
我是 Javascrript 的新手。我有一个具有以下详细信息的变量：
var result = false;
[{"a": "1","b": null},{"a": "2","b": 5}].forEach(function(call){
console.log(call);
var a = call['a'];
var b = call['b'];
if(a == null || b == null){
result = false
break;
}
});
I want to break the loop if there is NULL value for a key. How can I do it?
如果键有 NULL 值，我想中断循环。我该怎么做？

Do not use .forEach then but for loop:
不要使用 .forEach then 而是 for 循环：
var myObj = [{"a": "1","b": null},{"a": "2","b": 5}]
var result = false
for(var call of myObj) {
console.log(call)
var a = call['a'], b = call['b']
if(a == null || b == null) {
result = false
break
}
}
