jquery 做出专业的界面，SHOW 一下最近的成果~~~

最近在项目中把整个UI框架重新做了一下，都是用Jquery实现的，没有使用EXT、EasyUI那一类的UI框架再也不用担心版权问题啦~~~~~~

接下来我会在博客中把常用的功能分享出来，先上一下动态Tab的，功能基本和EasyUI里的tab类似。

实现原理:

1、点击菜单项新增一个div然后在div里打开一个iframe。

2、有了div当容器就很好控制样式，让tab看起来很舒服。

3、tab的切换其实就是div的隐藏和显示。

4、通过把页面的名称存放到div的属性里可以防止重复打开div。

5、控制div的总个数可以防止用户打开过多的页面。

效果图如下：

Jquery代码如下：

//=================动态tab标签========================
function AddTabMenu(tabid, _url, name, img, Isclose) {
    try {
        var url = _url;
        if (url == "" || url == "#") {
            url = "/WMSErrorPage/404.aspx";
        }
        top.$("#Current_iframe").val("div_" + tabid);
        if (Isclose != 'false') { //判断是否带关闭tab
            top.$(".navigation").hide();
            top.$("#side_switch").hide();
        } else {
            top.$(".navigation").show();
        }
        ///如果当前tabid存在直接显示已经打开的tab
        if (top.document.getElementById("div_" + tabid) == null) {
            Loading(true);
            //遍历并清除开始存在的tab当前效果并隐藏其显示的div
            var tablist = top.document.getElementById("div_tab").getElementsByTagName('li');
            var pannellist = top.document.getElementById("ContentPannel").getElementsByTagName('iframe');
            if (tablist.length > 5) {
                showConfirmMsg('您当前打开太多页面,如果继续打开,会造成程序运行缓慢,无法流畅操作！', function (r) {
                    if (r) {
                        //创建iframe
                        var box = document.createElement("iframe");
                        box.id = "div_" + tabid;
                        box.name = "div_" + tabid;

Css样式如下

/*动态Tab

#div_tab li{float:left;text-align:center;position:relative;list-style:none;}

#div_tab li{height:30px;}
#div_tab li span{height:30px;line-height:29px;}

#div_tab li.crent{height:30px;}
#div_tab li.crent span{height:30px;line-height:29px;}

#div_tab li,#div_tab li.crent{color:#fff;background-repeat:no-repeat;background-position:0 0;}
#div_tab li span,#div_tab li.crent span{display:inline-block;padding:0 15px 0 0px;background-repeat:no-repeat;background-position:right bottom;}

#div_tab li .menua{color:#000;font-size:12px; text-decoration:none;position:relative;}
#div_tab li.crent .menua,#div_tab li .menua:hover{}
#div_tab li .win_close,#div_tab li.crent .win_close{width:13px;height:13px;position:absolute;top:8px;right:5px;cursor:pointer;display:block;overflow:hidden;background:url(../images/tab_delete_ico.png) no-repeat;}
#div_tab li .win_close{background-position:0 -10px;    position: absolute;
    z-index:;}
#div_tab li .win_close:hover{background-position:0 2px;}
#div_tab img
{
    vertical-align: middle;
    margin: 0px 5px 0px 0px;
    padding-bottom:3px;
}
.menuselected

   background:#FFF;
}
#dww-menu { width:auto;margin:auto; overflow:hidden;}
#dww-menu .mod-hd li { float:left; cursor:pointer; text-align:center; height:30px; line-height:29px; padding:0 10px; letter-spacing:1px; text-transform:uppercase; border-right:1px #dcdcdc solid }

当然图片就先晒到这边啦！如果你觉得可以把这些图片的设计思路理解，并且觉得以后会用的话，请收藏一下，推荐一下啦!

对于一些界面看完让我内心想对他说三个字"毁三观"的界面，我只能说你的审美水平一定要提高的，IT这是一个潮流的行业，如果你不潮，那就无法与众不同，机遇往往会给你留个位置的！大家说呢？
