怎么将JS里面的变量传递到PHP里面去

将需要传送的变量(array/object等)编码为JSON格式，发送到服务器端由PHP解码即可，下面是实现方式，注意这个方法在Firefox下是原生的，下面的代码适用于非Firefox浏览器

Object.prototype.getSource = function() {

    var output = [], temp;

    for (var i in this) {

        if (this.hasOwnProperty(i)) {

            temp = i + ":";

            switch (typeof this[i]) {

                case "object" :

                    temp += this[i].getSource();

                    break;

                case "string" :

                    temp += "\"" + this[i] + "\"";    // add in some code to escape quotes

                    break;

                default :

                    temp += this[i];

            }

            output.push(temp);

        }

    }

    return "{" + output.join() + "}";

}

 

alert(['a', 'b', 'c'].getSource());
