这篇翻译不完整。请帮忙从英语翻译这篇文章

The FormData.entries() 方法返回一个 iterator对象 ,此对象可以遍历访问FormData中的键值对。其中键值对的key是一个 USVString 对象;value是一个 USVString , 或者 Blob对象。

Note: 此方法在 Web Workers 可用.

语法

formData.entries();

返回值

返回 iterator

示例

// Create a test FormData object
var formData = new FormData();
formData.append('key1', 'value1');
formData.append('key2', 'value2');

// Display the key/value pairs
for(var pair of formData.entries()) {
   console.log(pair[0]+ ', '+ pair[1]); 
}

执行结果为:

key1, value1
key2, value2
