Front-end framework-pop-up window research

I have been working in an electric power company for two years, and all the applications developed are based on H5 applications. The H5 reference is developed based on the cordova.js library. When various outsourcing companies received the application, they were all confused and did not know how to develop it. This article mainly explains the use of a front-end built based on the seajs library and the Bootstrap framework. Universal framework.

The front-end framework mainly studies four points

1. ResearchThe dynamic loading technology of the Web framework

For In the mobile Internet environment, mobile terminals have limited memory, traffic, and battery resources. By using dynamic loading technology, program files are broken into multiple small files, and lazy loading technology (LazyLoading) is used to achieve on-demand loading to improve user experience. Reduce resource usage on mobile terminal. In terms of business and style, front-end developers only need to reference the required js library and css style at the head of the JS code block. Logically, developers only need to call the interface provided by the backend to read and display. The main advantages of this technology include high maintainability, fast dynamic loading, and good front-end performance optimization.

2. Research on modularizationBuilding technology

Based on the development of mobile application projects by front-end personnel, by using modular construction technology, Each page is divided into multiple functions for segmentation processing, which can not only quickly obtain the page on the mobile terminal, but also quickly locate related problems during debugging on the mobile terminal. By defining multiple modules to call each other, it not only ensures that there is no conflict between modules, but also improves the coding efficiency of developers. Its main advantages are single responsibility and close dependence.

3. Research on multi-resolution and multi-size mobile terminal interface adaptation technology

For various terminal devices on the mobile side, based on the bootstrap framework On the basis of, a unified style is set through the media query function (Medie Query), and equal proportion windows are set through the window (meta) attribute content. This solves the problem of different mobile phone models with different resolutions and different sizes of terminals being unable to adapt. , further reducing code redundancy and redevelopment.

4. Study on the encapsulation of public components on the mobile terminal

Based on the limited encapsulation of some components under the bootstrap framework, through the time plug-in (datatime), pop-up window plug-in (dialog), graphics plug-in (echarts), pull-down refresh and pull-up loading plug-in (Refresh), sliding plug-in (swiper), province and city selection (citypicker) plug-in, prompt information plug-in (UED) ) and other plug-ins are encapsulated, called on demand, and loaded on demand, so that different pages can reference different plug-ins and implement the calling of components, which greatly reduces the time of front-end developers and also improves the user experience.

Here, we will use one of the plug-ins-the pop-up window to explain

Let me show you the renderings first

Pop-up windows are basically used in every application, and there are so many kinds of pop-up windows. Many programmers, here Write one set, write another over there, the code is very messy, here I also found a set on the Internet, and sorted it out myself. I hope everyone will use a common set of codes in the future to make it concise and simple.

Front-end h5 code

The h5 page should be concise and simple, and separate css and js logic codes are not allowed (the following css code is for testing)

    <meta>
    <meta>
    <title>首页</title>
    <meta>
    <style>.col-xs-6 {
            padding: 10px 1px;
        }</style>

                <button>bootstrap弹窗</button>
            </div>
            <div>
                <button>无标题</button>
            </div>
        </div>
    </div>
    <script>
        <div id="dialogContent">这里是用户获取到的内容,获取的内容，可直接设置在这里，然后在页面显示</script>

         <script>var basepath = "../../";//定义当前目录的位置（如果全部在根目录的话，则不需要定义）</script>     <script></script>          <script></script>          <script>seajs.use("../js/dialogs");</script>

View Code

The above code uses my general framework code. If you use pop-up windows, you can directly quote the dialog. js, dialog.css, jquery.js and dialogtest.js can

dialogtest.js code is as follows

define(function (require) {
    require("bootstrap");//加载bootstrap
    require('dialog');//加载弹窗  
    require('dialogcss');//加载弹窗  
  
 
    var modal = new Modal({
        title: '测试案例',
        content: $('#modal-tpl').html(),
        width: "90%",
        onOk: function () {
            //操作
            alert("你点击了确定");
        },
        onModalShow: function () {
            //弹窗初始化操作
            
        }
    });
    $(".btn").each(function (index) {
        $(this).on("click", function () {
            if(index==0)
            {
                $('body').dailog({ type: 'defalut' });
            }else if(index==1)
            {
                $('body').dailog({ type: 'success' })
            }
            else if (index == 2) {
                $('body').dailog({ type: 'primary' })
            }
            else if (index == 3) {
                $('body').dailog({ type: 'danger' })
            }
            else if (index == 4) {
                $('body').dailog({ type: 'warning' })
            }
            else if (index ==5) {
               $('body').dailog({ type: 'success', maskBg: 'rgba(33,11,22,0.5)' })
            }
            else if (index ==6) {

                    type: 'danger', title: '我是自定义标题', 
                    discription: '这里是自定义的描述，可以写上你的描述或者他的描述，总之可以写很多文字，你自己看着办吧'
                }, function (ret) {
                    if (ret.index == 0)
                    {
                        alert("你点击了确定按钮");
                    } else
                    {
                        alert("你点击了取消操作");
                    }
                    console.log("信息为："+JSON.stringify(ret));
                })
            } else if (index ==7) {
                $('body').dailog({
                    type: 'danger', title: '错误提示',
                    discription: '这里是自定义的描述，可以写上你的描述或者他的描述，总之可以写很多文字，你自己看着办吧',
                    isInput: true
                }, function (ret) {
                    console.log(ret);
                    if (ret.index === 0)
                    {
                        alert('你点击的是第' + ret.index + '个按钮,状态:' + ret.input.status + ';输入的值为:' + ret.input.value)
                    };
                });
            } else if (index == 8) {
                $('body').dailog({ type: 'defalut', showBoxShadow: true })
            } else if (index ==9) {
