2010-06-24 09:35

模态窗口返回值是个很好用的东西，给用户体验带来了方便的同时，也可能为程序的数据格式规范带来便利。

值得一提的是window.returnValue只有一个返回值，如果要返回多个返回值就需要对这个返回值

进行处理可以适当加连接符&，-，+等等，returnValue类型不限制，对于字符串类型，最大为4096个字符。

var array = a.split( "&");

window.document.getElementById("textbox1").value = array[0];
window.document.getElementById("textbox2").value = array[1];
