如何在javascript中脱离foreach循环

Question

我是Javascrript的新手.我有一个变量有以下细节:

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;
    }
});

如果键的值为NULL,我想打破循环.我该怎么做？

Answer 1

不要使用.forEach然后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
    }
}
