说明:如果对话框内容为单独网页,需要与LeesAjaxRequest.js结合使用
使用示例:
//ie browser
if (vBrowser.isIE) {
document.onreadystatechange = function() {
if (document.readyState=="complete") {
doInit();
}
}
//firefox browser
}else {
document.addEventListener("DOMContentLoaded", doInit, false);
}
function doInit()
{
//从网页中动态加载对话框内容
dlg=new LeesDialogWindow(330,310,"title","id","","/xxxx/xxxx/subjectmanage.htm?ver4","");
dlg.ShowWindow();//先显示,再关闭;显示的目的是使动态创建的网页元素可用
dlg.CloseWindow();//关闭的目的,是因为当前用不着它
getSubjectList();
var str_loading="<div unselectable=\"on\" style=\"_moz-user-select:none;margin:20px auto;font-size:15px;font-weight:bold;text-align:center;width:150px;height:30px;\">正在传输数据……</div>"
+"<div unselectable=\"on\" style=\"_moz-user-select:none;margin:10px auto;text-align:center;width:40px;height:40px;\"><img src=\"/images/loading01.gif\" alt=\"正在加载\" /></div>";
//对话框内容为指定HTML字符串
//"请等待","正在加载..." 这样一个对话框
dlg_loading=new LeesDialogWindow(220,150,"请等待","loading","","",str_loading);
dlg_loading.ShowWindow();
dlg_loading.CloseWindow();
dlg_loading.closeButton.style.display="none";
dlg_loading.contentWindow.style.MozUserSelect="none";//FF下不允许选中内容
dlg_loading.contentWindow.unselectable="on";//IE下不允许选中内容
}
