/**
* 在页面上弹出窗口
* @param showModal 是否弹出模式窗口。如果为true则弹出模式窗口；否则弹出非模式窗口。
* @param refreshParent 当关闭弹出的模式窗口时，是否刷新父窗口。如果为true则刷新父窗口；否则不刷新父窗口。该参数只对弹出模式窗口有效。
* @param url 弹出窗口的URL
* @param feature 弹出窗口的特征。特征值间用分号分隔，可设置的特征值有：
*      dialogHeight
*     dialogLeft
*         dialogTop
*         dialogWidth
*         center:{ yes | no | 1 | 0 | on | off }
*         dialogHide:{ yes | no | 1 | 0 | on | off }
*         edge:{ sunken | raised }
*         help:{ yes | no | 1 | 0 | on | off }
