我想知道座位号何时不在数组中，但它像indexOf（）同时读取键和值。请问我该如何解决这个问题

data1是这种类型的数组：Array（[0] =＆gt; 1 [1] =＆gt; 2 [2] =＆gt; 3 [3] =＆gt; 4 [4] =＆gt; 5 [ 5] =＆gt; 6 [6] =＆gt; 7 [7] =＆gt; 8 [8] =＆gt; 9 [9] =＆gt; 10 [10] =＆gt; 11 [11] =＆gt; 12 [12] ] =＆gt; 13 [13] =＆gt; 14 [15] =＆gt; 16），我有16个座位，我想知道座位何时不再可用。当数据阵列中不再存在时，座位不可用1。我使用indexOf（）来做到这一点，但是没有用完

Answer 1

你的数据是json对象的类型而不是数组，所以你应该做

data1.indexOf["0"] to access value

因此，对于值，您可以迭代键并比较值：

for(key in data) {
   if(data[key] == toFindInt)
       console.log("found")
}
