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() {

    varoutput = [], temp;

    for(vari inthis) {

        if(this.hasOwnProperty(i)) {

            temp = i + ":";

            switch(typeofthis[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());
