2、功能实现

导入jQuery

<script type="text/javascript" src="js/jquery-1.8.2.min.js"></script>

<!--导入自定义的jQuery脚本-->

<script type="text/javascript" src="js/Form_menu.js"></script>

注意：自定义的jQuery是否可以放在原生的jQuery上面呢？不可以：咱们自己写的jQuery调用的也是原生的jQuery，如果原生的jQuery没有加载，咱们自定义的也是不可以用的。

编写CSS代码

首先我们要给，右上角的“进入编辑模式”添加一个事件，我们可以通过这个事件给“进入编辑模式”新增一个属性，或者样式，通过这个属性和样式，来判断是否进入了编辑模式，在上一篇我自己写的是使用的属性，这次我们来使用样式来判断。

在css文件里新增两个样式：

/*定义编辑按钮的样式*/

.edit-mode{

    background-color: #b3b3b3;

    padding: 8px;

    text-decoration: none;

    color: white;

}

/*定义点击编辑按钮后的样式*/

.editing{

    background-color: #f0ad4e;

}

增加自定义的js文件实现各个功能

             var check_box = tr.children().first().find(':checkbox');//周到所有的checkbox标签

             if(check_box.prop('checked')){ //判断是否选中

                 check_box.prop('checked',false);//如果选中，给他设置为为选中

             }else{

                 check_box.prop('checked',true);//如果没有选中，给他设置为选中

 }

 //设置取消功能

 function CheckCancel(mode, tb){

     // 1、取消选中checkbox

     // 2、如果已经进入编辑模式，行退出编辑状态

     $(tb).children().each(function(){ //渠道所有的tr标签，并循环

     });

JS代码

文档处理

看下面的图片效果：

问：我想在点击加的时候在下面新增一个搜索条件框体，点击减号的时候删除当前这个框体怎么实现？

1、文档操作基础

看下面的例子：

在后面追加内容（可以是文本，可以是标签类型）：

<!DOCTYPE html>

<html lang="en">

<head>

    <meta charset="UTF-8">

    <title>shuaige</title>

</head>

<body>

    <div id="i1">

    </div>

    <div id="i2" style=" padding: 0px; color: rgb(0, 0, 255); line-height: 1.5 !important;">>

    </div>

    <script type="text/javascript" src="../js/jquery-1.8.2.min.js"></script>

    <script>

        $('#i1').append('<a>Hello Test Append</a>');//对这个id#i1的标签内尾部增加一条数据

        $('#i1').append('<div>Test Continue</div>');//对这个id#i1的标签内尾部增加一条数据

        $('#i1').prepend('<div>Prepend on the chiled tables</div>');//对这个id为i1的自标签内顶部增加一条数据

        $('#i1').appendTo('#i2'); //想让某一个标签添加到某一个和标签，可以用到appendTo，把i1放到i2里面了

        $('#i1').before('<h1>append content  same level up</h1>');//放在找到的'#i1'同级标签上面增加

        $('#i1').after('<h2>append content same level down</h2>');//放在知道的'#i1'统计标签下面增加

    </script>

</body>

</html>

2、分析

上面的例子，按照行分割一步一步的写，看效果。那么返回来看上上面开始说的

我想在点击加的时候在下面新增一个搜索条件框体，点击减号的时候删除当前这个框体怎么实现？

我要增加，怎么实现呢。clone （克隆-复制）

<!DOCTYPE html>

<html lang="en">

<head>

    <meta charset="UTF-8">

    <title>shuaige</title>

</head>

<body>

    <div id="search_conditions">

        <div class="condition">

            <a onclick="AddCondition(this,'#search_conditions')">+</a>

            <input/>

        </div>

    </div>

    <script type="text/javascript" src="js/jquery-1.8.2.min.js"></script>

    <script>

        //添加新增内容

        function AddCondition(ths,condition){

            //copy condition div

            //在吧copy的div追加到id="search_condition"的标签内下面

            var cp = $(ths).parent().clone();

            console.log(cp);

            //修改里面的内容,和属性

            cp.children(':first').text('-').attr('onclick',"RemoveCondition(this,'#search_conditions')");

            cp.appendTo('#search_conditions');

        }

        //新增完后的标签内新增的内容

        function RemoveCondition(ths,condition){

            $(ths).parent().remove();

        }

    </script>

</body>

</html>

效果图如下（样式可以后续加上）：

jQuery扩展

1、什么是jQuery的扩展

首先要了解下，python中给咱们提供和很多现成的模块，但是他的模块够用吗？不够用那怎么办？导入第三方的模块，使用现成的模块操作快捷方便！

http://www.php100.com/manual/jquery/，中有一个叫做“插件机制”：

jQuery.fn.extend(object)

jQuery.extend(object)

2、jQuery.extend(object)

html代码如下：

<!DOCTYPE html>

<html lang="en">

<head>

    <meta charset="UTF-8">

    <title>shuaige</title>

</head>

<body>

    <script type="text/javascript" src="jquery-1.8.2.min.js"></script>

    <!--这里必须优先导入jQuery原生的js，在导入扩展的jQuery-->

    <script type="text/javascript" src="extends.js"></script>

    <script>

        console.log($.luotianshuai())

    </script>

</body>

</html>

jQuery代码如下：

//扩展使用自执行函数来写,逼格比较高点

(function (arg) {

    arg.extend({

        'luotianshuai':function (){

            return 123;

        },

        'login':function(){}  //他的代码是以字典形式存储的扩展jQuery

    })

})(jQuery);//jQuery为传进去的函数他的方程式:(function (arg) {})();第一个括号为函数,第二个括号内存储参数

3、jQuery.fn.extend(object)

jQuery.fn.extend(object) 这个方法和jQuery.extend(object)的区别就是，jQuery.fn.extend(object)可以传入搜索参数

jQuery.fn.extend({

  check: function() {

    return this.each(function() { this.checked = true; });

  },

  uncheck: function() {

    return this.each(function() { this.checked = false; });

  }

});

结果：

$("input[type=checkbox]").check();

$("input[type=radio]").uncheck();

4、form表单验证（下面的两个例子基本上功能就够用了）

看下面的jQuery代码和html代码

 form_authentication_extend

 login_form_html

 register_form_html

还有两个比较不错的扩展连接：

-- parsleyjs
    http://parsleyjs.org/
-- jQuery Validate
    http://jqueryvalidation.org/
如果是简单功能自己写就行了，毕竟链接里的东西，比较多简单功能咱们自己实现即可。

使用插件

1.4根据自己的需求修改他的样式和图片

BootStrap框架

1、BootStrap介绍

说BootStrap其实他是一个类库，定了一些js方法和css

网页编程：http://v3.bootcss.com/getting-started/ （从起步开始一步一步学）

Bootstrap 是一个用于构建响应式网站的前端框架。无论你想构建应用程序、博客还是 CMS 网站,Bootstrap 都完美适用,只要你想得到, 它都能行。

Bootstrap 把 HTML、CSS 和 JavaScript 组合起来,为构建稳定的网站提供了基础设施,也能提高开发效率。

基于默认的网格系统,布局变成了小菜一碟,按钮、导航和表格也都活脱脱地赏心悦目。十几个 JavaScript 插件更为我们赋予网站交互能力提供了强大保障。

响应式布局：根据用户设备的不同，进行相应的布局！（根据浏览器的宽度设置）

Bootstrap 是 Mark Otto 和 Jacob Thornton 共同开发的一个开源框架。最初发布 Bootstrap 的时候,他们两位都在 Twitter 工作。当时,他们面临着为公司内部提供一套标准化的前端开发工具的需求。在发布 Bootstrap 的那篇博客中,Mark Otto 这样介绍他们的新项目:
Twitter诞生初期,为了完成前端开发任务,工程师们几乎尝试了自己熟悉的所有库。应用之间的不一致性导致它们难以扩展和维护。Bootstrap最初就是这个问题的一个解决方案,而且在Twitter内部第一次Hackweek上得到了认可。Hackweek结束后,我们手头上的项目已经相当稳定,可以在公司内部部署使用了。
--Mark Otto
https://dev.twitter.com
Bootstrap 是 2011 年 8 月发布的,发布之后就迅速走红。而且,它也从最初 CSS 驱动的项目,发展到内置了很多 JavaScript 插件和图标, 并且涵盖了表单和按钮元素。Bootstrap 本身支持响应式 Web 设计, 而且拥有一个非常稳健的 12 列、940 像素宽的网格布局系统。值得一提的是,Bootstrap 网站(http://getbootstrap.com)上还提供了一个构建工具,让你根据自己的需求选择 CSS 和 JavaScript 功能。所有这一切让前端 Web 开发有了前瞻性的设计和开发基础,开发效率倍增。上手使用 Bootstrap 非常简单,跟在网站中整合 CSS 和 JavaScript 没有什么区别。

eot、svg、ttf、woff、woff2

    @font-face语句是css中的一个功能模块，用于实现网页字体多样性的模块(设计者可随意指定字体，不需要考虑浏览者电脑上是否安装)。

    而由于网页中使用的字体类型，也是各浏览器对字体类型有不同的支持规格。 字体格式类型主要有几个大分类：TrueType、Embedded Open Type 、OpenType、WOFF 、SVG。

    eot  EOT– Embedded Open Type

        EOT是嵌入式字体，是微软开发的技术。允许OpenType字体用@font-face嵌入到网页并下载至浏览器渲染，存储在临时安装文件夹下。

    SVG Scalable Vector Graphics

        SVG是由W3C制定的开放标准的图形格式。SVG字体就是使用SVG技术来呈现字体，还有一种gzip压缩格式的SVG字体。

    ttf TrueType

        Windows和Mac系统最常用的字体格式，其最大的特点就是它是由一种数学模式来进行定义的基于轮廓技术的字体，这使得它们比基于矢量的字体更容易处理，保证了屏幕与打印输出的一致性。同时，这类字体和矢量字体一样可以随意缩放、旋转而不必担心会出现锯齿。

    woff WOFF–WebOpen Font Format

        WOFF（Web开发字体格式）是一种专门为了Web而设计的字体格式标准，实际上是对于TrueType/OpenType等字体格式的封装，每个字体文件中含有字体以及针对字体的元数据（Metadata），字体文件被压缩，以便于网络传输。

3、HTML样板（根据自己需求修改）

复制代码

复制代码

"""

<meta charset="utf-8">

    编码

<meta http-equiv="X-UA-Compatible" content="IE=edge">

    Bootstrap 不支持 IE 古老的兼容模式。为了让 IE 浏览器运行最高级别的可用模式渲染显示内容

<meta name="viewport" content="width=device-width, initial-scale=1">

    为了确保适当的绘制和触屏缩放，需要在 <head> 之中添加 viewport 元数据标签。

    在移动设备浏览器上，通过为视口（viewport）设置 meta 属性为 user-scalable=no 可以禁用其缩放（zooming）功能。这样禁用缩放功能后，用户只能滚动屏幕，就能让你的网站看上去更像原生应用的感觉。

　　 注意，这种方式我们并不推荐所有网站使用，还是要看你自己的情况而定！

<meta name="renderer" content="webkit">

    国内浏览器厂商一般都支持兼容模式（即 IE 内核）和高速模式（即 webkit 内核），不幸的是，所有国产浏览器都是默认使用兼容模式，这就造成由于低版本 IE （IE8 及以下）内核让基于 Bootstrap 构建的网站展现效果很糟糕的情况。

　　 幸运的是，国内浏览器厂商逐渐意识到了这一点，某些厂商已经开始有所作为了,目前只有360浏览器支持此 <meta> 标签。希望更多国内浏览器尽快采取行动、尽快进入高速时代！
