URL编码的JavaScript数组

是否有任何js函数可以将数组转换为URL编码？ 我完全是新手n JS。。。谢谢

---

我的数组是一个键值数组。。。。 所以

与

myData['id']='354313';
myData['fname']='Henry';
myData['lname']='Ford';
myData.join('&'); //returns error, it doesn't work on such array...

有什么解决办法吗

---

哦，对不起。。。 我有一个这样的数组

var myData=new Array('id'=>'354313','fname'=>'Henry','lname'=>'Ford');

然后我需要将数组转换为：

id=354313&fname=Henry&lname=Ford

---

查看函数escape和。

您可以执行以下操作：

var myData = new Array('id=354313', 'fname=Henry', 'lname=Ford');
var url = myData.join('&');

试试这个：

var myData = {'id': '354313', 'fname':'Henry', 'lname': 'Ford'};
var out = [];

for (var key in myData) {
    if (myData.hasOwnProperty(key)) {
        out.push(key + '=' + encodeURIComponent(myData[key]));
    }
}

out.join('&');

---

有关为什么要使用

hasOwnProperty

的解释，请参阅jgrunds answer中的，如果您想扩展阵列功能

Array.prototype.toQueryString = function(){
    var out = new Array();

    for(key in this){
        out.push(key + '=' + encodeURIComponent(this[key]));
    }

    return out.join('&');
}

或者如果你想要一个独立的函数

function arrayToQueryString(array_in){
    var out = new Array();

    for(var key in array_in){
        out.push(key + '=' + encodeURIComponent(array_in[key]));
    }

    return out.join('&');
}

---

如果使用对象而不是数组，则可以执行此操作（ES6）：

---

如果使用jQuery，则可以使用$.param（）。检查。 使用示例

var myData = {'id' : '354313', 'fname' : 'Henry', 'lname' : 'Ford'};
var url = "https://stackoverflow.com?" + $.param(myData);

输出为

https://stackoverflow.com?id=354313&fname=Henry&lname=Ford

还可用于对象数组（如来自jQuery（form）.serializeArray（））：

recursiveEncoded和recursiveDecoded的值如下所示：

a%5B%5D=1&a%5B%5D=2&a%5B%5D%3&b%5B%5D=1&b%5B%5D=2&b%5B%5D=3 a[1]=1&a[2]=2&a[3]=3&b[]=1&b[]=2&b[]=3

---

晚会迟到了，但我提出的这个解决方案可以处理递归性和嵌套数组/对象

function is(className, object) {
    return Object.prototype.toString.call(object) === '[object '+ className +']';
}

const DataEncoder = function() {
    this.levels = [];
}

DataEncoder.prototype.__dataEncoding = function(data, actualKey = null) {
    let finalString = '';
    if (actualKey) {
        this.levels.push(actualKey);
    }

    const keys = Object.keys(data);
    const l = keys.length;
    for(let a = 0; a < l; a++) {
        const key = keys[a];
        let value = data[key];

        if (is('Object', value)) {
            finalString += this.__dataEncoding(value, key);
        } else if (is('Array', value)) {
            const arrValSize = value.length;
            for (let b = 0; b < arrValSize; b++) {
                let arrVal = value[b];
                if (actualKey) {
                    finalString += actualKey;
                    for(let c = 1; c < this.levels.length; c++) finalString += '[' + this.levels[c] + ']';
                    if (arrVal === undefined || arrVal === null) arrVal = '';
                    finalString += '[' + key + '][]=' + arrVal + '&';
                } else {
                    if (arrVal === undefined || arrVal === null) arrVal = '';
                    finalString += key + '[]=' + arrVal + '&';
                }
            }
        } else {
            if (actualKey) {
                finalString += this.levels[0];
                for(let c = 1; c < this.levels.length; c++) finalString += '[' + this.levels[c] + ']';
                if (value === undefined || value === null) value = '';
                finalString += '[' + key + ']=' + value + '&';
            } else {
                if (value === undefined || value === null) value = '';
                finalString += key + '=' + value + '&';
            }
        }
    }
    this.levels.pop();
    return finalString;
}

DataEncoder.prototype.encode = function(data) {
    if (!is('Object', data) || data === {}) return null;
    return this.__dataEncoding(data).slice(0, -1);
}

结果:

我知道它需要一个组件方法，但是可以很容易地添加

您是说对数组中的每个字符串进行URL编码，还是将它们连接到URL查询字符串或..？URL编码仅应用于字符串。如果希望将其应用于数组，首先需要解释这是什么意思-是否希望将数组连接到单个字符串中？是否要对单个数组元素进行编码？如何处理非字符串数组元素（如对象、函数或其他数组）？最好编辑您的问题，至少包含一个您希望实现的示例（原始数组，生成的url编码字符串）最好这样做：out.push（key+'='+encodeURIComponent（arr[key]）；有自己的财产是不必要的，这数据你摇滚！固溶体！
