jQuery 屏蔽页面再次被按和延迟加载函数

jQuery 屏蔽页面再次被按JS文件template_opt.js，内容如下

var common = {

//随机字符

1、调用方法:

//添加屏蔽功能

function addMask_load(){

common.addMask("#000",0.5);

//var strPath = window.document.location.pathname;

//var postPath = strPath.substring(0, strPath.substr(1).indexOf('/') + 1);

//alert(strPath);



var html = '<div id="load1234" style="width: 585px;height: 401px; top: 280px; left: 350px;position: absolute;z-index:1234;background: url(../images/alertBg.png) no-repeat;">';

html += '<div style=" position: absolute;">';

html += '<img src="../images/alertNtitle.jpg" width="585" height="55" border="0" />';

html += '</div>';

html += '<div style="position: absolute;width: 583px;height: 53px; font-size: 24px; font-weight: 600; line-height:50px;color: white;">';

html += ' 提示信息';

html += '</div>';

html += '<div style="position: absolute;width: 583px;height: 345px;margin-top: 54px;font-size: 24px; ">';

html += '<div style="margin-top: 60px;text-align:center;">';

html += '正在查询，请稍候...';

html += '</div>';

html += '</div>';

html += '</div>';



//alert(html);



$('body').prepend(html);



}

//取消屏蔽功能

function removeMask_can(){

common.removeMask();

var load1234Obj = $("#load1234");

if(load1234Obj)load1234Obj.remove();

}

2.延迟加载函数

//延时执行跳转或执行函数

//url可以为地址或者定义好的javascript/jquery函数,

//定义每次延时时间和延时次数,

//callback是每次延时可以执行的回调函数

//

//调用示例

//jump(function(){login(email, password);},3,500,function(){

// $('#register_panel .login_text .success').html($('#register_panel .login_text .success').html()+'.');

//});

function jump(url,times,count,callback) {

var type = typeof(url);

if(times) {

window.setTimeout(function(){

times--;

callback();

if(times > 0) jump(url,times,count,callback);

else {

type == 'function' ? url() : location.href = url;

}

}, count);

} else type == 'function' ? url() : location.href = url;

}
