Question

需要使用给定的对象创建特定的对象数组。现在，我已经使用了assign对象。

这里是

var str = [{componentName: "Transformer", type: "PUB", beanName: "TransformerExtractor", state: "enabled", config: {"test":"test"}},{componentName: "DBEE", type: "PUBSUB", beanName: "DBEErExtractor", state: "enabled", config: {"test":"test"}}];

var A1 = [];

var B1 = [];

finalOutput = [];

for(i=0;i<str.length;i++){

    alert(str.length);

    var output = {};

    output.flowId = "Flow1234";

    output.flowAlias = "Flow1234";

    output.description = "Flow1234";

    output.state = "Enabled";

    A1.push(output);

    alert (A1);

    B1.push(str[i]);

    alert (B1);

    finalOutput = [A1, B1].map(o => Object.assign({}, A1, o));
}

alert (finalOutput);

return finalOutput;

能否请您告诉我如何获得预期的结果，例如[{A1，B1（来自变量str的第一组），{A1，B1（来自变量str的第二组）]

从上次编辑中获取数据，您可以为要添加到数组中的对象的数据定义模板对象。

var data = [{ componentName: "Transformer", type: "PUB", beanName: "TransformerExtractor", state: "enabled", config: { test: "test" } },{ componentName: "DBEE", type: "PUBSUB", beanName: "DBEErExtractor", state: "enabled", config: { test: "test" } }],
    template = { flowId: "Flow1234", flowAlias: "Flow1234", description: "Flow1234", state: "Enabled" },
    result = data.map(o => Object.assign({}, template, o));

console.log(result);

.as-console-wrapper { max-height: 100% !important; top: 0; }

如果只想合并它们，可以使用lodash

data = _.merge(A1, B1)

使用JS将多个对象添加到数组中
