Question

在下面给出的代码中，我可以在MS Edge中附加数据，但是在读取该值时，我没有给Microsoft的任何选择。有什么解决方法可以读取已经附加的值？任何帮助，将不胜感激。谢谢！

let formData = new FormData();
formData.append("Key1", "Key1-Value1");

formData.get("Key1"); // Not Supported in Edge
formData.getAll();    // Not Supported in Edge
formData.entries();   // Not Supported in Edge
formData.keys();      // Not Supported in Edge
formData.value();     // Not Supported in Edge

在我看来，您可以定义一个数组以将实体存储在前端，然后可以从该数组中筛选数据，而不是FormData。请参考以下代码：

var datalist = []; //define an array to store the formdata entities.

let formData = new FormData(); //the formdata, you could send it to server side.

formData.append("Key1", "Key1-Value1");
formData.append('Key1', 'Chris');
formData.append('Key2', 'Bob');

//push data into the array.
datalist.push({ Key: "Key1", value: "Key1-Value1" });
datalist.push({ Key: "Key2", value: "Chris" });
datalist.push({ Key: "Key3", value: "Bob" });

//based on the key value to filter entities.
var entity = jQuery.grep(datalist, function (item) {
    return item.Key == "Key1";
});

//get all keys.
var allkeys = jQuery.map(datalist, function (item) {
    return item.Key;
});

//get all values.
var allvalues = jQuery.map(datalist, function (item) {
    return item.value;
});

如果我在断点或其他任何地方，请转到“控制台”选项卡，然后输入console.log(...formData)
