Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

w5c-validator

w5cValidator 插件基于angular.js原有的表单验证,统一验证规则和提示信息,在原有的基础上扩展了一些错误提示的功能,让大家不用在每个表单上写一些提示信息的模板,专心的去实现业务逻辑。 w5c validator自身提示信息样式使用了bootstrap的方式,当然你可以很好的扩展自己的提示方式(比如tooltip等)

demo演示:http://why520crazy.github.io/angular-w5c-validator

Change Log:https://github.com/why520crazy/angular-w5c-validator/blob/master/CHANGELOG.md

Useage:

  1. HTML 中引用 w5cValidator.js,执行 npm i ng-w5c-validator 或者 npm i angular-w5c-validator 或者 bower install angular-w5c-validator 进行安装;

  2. 启动module引用 "w5c.validator",如: var app = angular.module("app", ["w5c.validator"]);

  3. app.config事件中配置全局属性和显示规则:

     app.config(["w5cValidatorProvider", function (w5cValidatorProvider) {
    
            // 全局配置
            w5cValidatorProvider.config({
                blurTrig   : false,
                showError  : true,
                removeError: true
    
            });
            w5cValidatorProvider.setRules({
                email   : {
                    required: "输入的邮箱地址不能为空",
                    email   : "输入邮箱地址格式不正确"
                },
                ...
            });
        }]);
  4. 在HTML模板中form上使用指令 w5c-form-validate 和 w5c-submit,w5c-form-validate指令表示该表单采用 w5cValidator的验证规则;w5c-submit 表示验证成功后调用的事件,当然w5c-submit可以不填写;

    <form class="form-horizontal w5c-form demo-form" role="form"
          w5c-form-validate="vm.validateOptions" novalidate name="validateForm">

#验证规则 AngularJS原生支持很多种验证规则,比如:require(必填项),email,pattern(正则),maxlength,minlength,number,url,max,min

w5cValidator提供了w5c-repeat(级联重复,常用于重复密码)和w5cUniqueCheck (远程验证,常用于检验用户名邮箱是否存在)

  1. w5cDynamicName , 让name支持表达式, <input w5c-dynamic-name="vm.dynamicName" />
  2. w5cDynamicElement 指令用于带 ng-if 或者 ng-repeat 内部的验证元素, 常常和 w5cDynamicName 配合使用

#默认提示信息

{
    required      : "该选项不能为空",
    maxlength     : "该选项输入值长度不能大于{maxlength}",
    minlength     : "该选项输入值长度不能小于{minlength}",
    email         : "输入邮件的格式不正确",
    repeat        : "两次输入不一致",
    pattern       : "该选项输入格式不正确",
    number        : "必须输入数字",
    w5cuniquecheck: "该输入值已经存在,请重新输入",
    url           : "输入URL格式不正确",
    max           : "该选项输入值不能大于{max}",
    min           : "该选项输入值不能小于{min}"

}

可以通过 w5cValidatorProvider.setDefaultRules(rule)进行设置做国际化

#注意事项:

  1. 由于验证使用的是 angular的form验证,所以必须要保证form和验证的元素都要有name属性;
  2. 如果你不想把验证成功事件w5c-submit写在 form上,可以直接在form里面的其他元素上使用w5cFormSubmit指令,如: <button type="buttom" w5c-form-submit="vm.saveEntity()" class="btn btn-success"> 验证</button>
  3. 如果你clone了代码。本地用chrome直接打开example/index.html是不可以运行的,因为我使用了$http服务去获取 js css html,所以必须要在本地搭建服务端程序,如果你有nodejs环境,运行npm install 安装module后再运行 grunt server , 如果没有grunt,用命令npm install grunt-cli -g安装, mac下需要 sudo npm install grunt-cli -g
  4. 如果你不想安装node grunt等乱七八糟的玩意,直接打开example/index-local.html 即可运行。
  5. w5cUniqueCheck默认检验是否已经存在,存在验证不通过,不存在验证通过,如果isExists设置为false表示:存在验证通过,不存在验证不通过。
  6. w5cValidatorProvider默认的错误提示信息是中文的,如果想修改成其他语言,可以通过 w5cValidatorProvider.setDefaultRules()方法设置。
  7. w5cDynamicName和w5cDynamicElement通常用于 循环创建表单元素,但是提示信息往往是一样的,默认的提示规则是按照name定义的, 所以提供了一种特殊的命名方式 {name}{$数字$}, 当匹配错误提示的时候,如果name后面带有 $数字$,会忽略这个,常用于 ng-repeat创建元素

#参数

|名称|默认值|作用| |------|-----|------| |blurTrig|false|光标移除元素后是否验证并显示错误提示信息| |showError|true|可以是bool和function,每个元素验证不通过后调用该方法显示错误信息,默认true,显示错误信息在元素的后面。| |removeError|true|可以是bool和function,每个元素验证通过后调用该方法移除错误信息,默认true,验证通过后在元素的后面移除错误信息。|

showError Function为

function showError(elem, errorMessages){
    ...
}

removeError Function为

function removeError(elem){
    ...
}

设置代码为:

 w5cValidatorProvider.config({
    blurTrig: false,
    showError: function(elem,errorMessages){
        ...
    },
    removeError: function(elem){
        ...
    }
  });
