应该怎么改呢？

window.form = this.options.form;

var $iframe = $("<iframe id='inp' name='inp' width='100%' height='100%' scrolling='no' frameborder='0'>");

$iframe.attr("src", "${servletURL}?reportlet=123.cpt&op=write&__showtoolbar__=false");

var o = {

title : "P15、G18アプロード",

width : 800,

height: 800

};

FR.showDialog(o.title, o.width, o.height, $iframe,o);
