插件：警告弹窗

纯原生js实现PC移动端都能用，不需要额外引入其他依赖即插即用

警告弹窗的图标是用base64写的不需要额外引入图片，

组件的css也写在js里其目的尽量减少引入需要以达到只需引用一个js就能即插即用，

虽然稍微缺失一点点性能。。。

调用代码：

<button id="d1">success</button>
<button id="d2">warning</button>
<button id="d3">error</button>
<button id="d4">info</button>

// 弹窗类型：success, warning, error, info
document.getElementById('d1').onclick = function () {
    new infoPromptBox({
        type: 'success',
         600,
        showTime: 4000,
        title: 'success'
    })
}
document.getElementById('d2').onclick = function () {
    new infoPromptBox({
        type: 'warning',
         500,
        showTime: 3000,
        title: 'warning'
    })
}
document.getElementById('d3').onclick = function () {
    new infoPromptBox({
        type: 'error',
         400,
        showTime: 2000,
        title: 'error'
    })
}
document.getElementById('d4').onclick = function () {
    new infoPromptBox({
        type: 'info',
         300,
        showTime: 1000,
        title: 'info'
    })
}

插件源码：

(function () {
    function infoPromptBox(option) {
        if (!document.getElementById('infoPromptBoxStyle')) { //添加样式
            var style = document.createElement('style');
            style.type = 'text/css';
            style.id = 'infoPromptBoxStyle'
            style.innerHTML=`
