javascript將數組轉換為字符串

Question

您好，我有2個數組，我想將它們放在單個字符串中。 我的數組可以接受從0到maxNum-1的值。 所以可以說我有myArray1 [i]和myArray2 [i]我想制作一個像這樣的字符串：

string = "myArray1ID" + 1 + "=" + (myArray1[1])
    + "&" +"myArray2ID" + 1 + "=" + (myArray2[1])
    + "&" + "myArray1ID" + 2 + "=" + (myArray1[2])
    + "&" + "myArray2ID" + 2 + "=" + (myArray2[2])
    + ......
    + "myArray1ID" + (maxNum - 1) + "=" + (myArray[maxNum-1])
    + "&" "myArray2ID" + (maxNum - 1) + "=" + (myArray2[maxNum-1]);

可能嗎？

Answer 1

使用循環的力量。

var output = [];

for (var i = 1; i < maxNum; ++i) {
    output.push(
        'myArray1ID' + i + '=' + myArray1[i],
        'myArray2ID' + i + '=' + myArray2[i]
    );
}
return output.join('&');

Answer 2

var myString = '';

for(var i; i < myArray1.length; i++){
  myString += "myArray1ID" + i + "=" + (myArray1[i]) + "&";
  myString += "myArray2ID" + i + "=" + (myArray2[i]) + "&";
}

//remove trialing "&"
var myString = myString.substring(0, myString.length-1);

假設兩個數組的長度相等

Answer 3

使用循環：

var stringArray = sep = ""; 
for(var i = 1; i < maxNum; i++) {
    stringArray += sep + "myArray1ID" + i + "=" + myArray1[i];
    stringArray += "&myArray2ID" + i + "=" + myArray2[i];
    sep = "&";
}

var stringArray應該包含您的數組值。
