在H5移动端项目开发过程,肯定会遇到不少与客户打交道的弹出框。
当然基于H5+ API中有提供系统的弹出对话框,虽然能够达到效果,但是实际的美观是几乎不存在的。
应项目需要,草草的写了一个弹出框的效果。
作为程序猿代码是最敏感的,废话也少说了,直接看下面的代码:
css代码部分:
#lee-mask { background: #000; opacity: 0.7; position: absolute; z-index: 1000; top: 0; left: 0; right: 0; bottom: 0; display: none; } #lee-content-wrap { position: absolute; z-index: 1001; left: 50%; top: 50%; margin-left: -150px; margin-top: -100px; background: #fff; box-shadow: 0 0 15px rgba(0, 0, 0, .5); display: none; } #lee-content { position: relative; width: 300px; height: auto; } /* title */ #lee-content .title { position: absolute; top: 0; left: 0; padding: 0 30px; box-sizing: border-box; width: 100%; height: 50px; line-height: 50px; background: #0B1F35; color: #fff; } /* content */ #lee-content .content-wrap { position: absolute; top: 50px; left: 0; width: 100%; bottom: 40px; padding: 10px; box-sizing: border-box; } /* footer */ #lee-content .footer { position: absolute; bottom: 0; left: 0; width: 100%; height: 40px; line-height: 40px; } #lee-content .footer .btn-group { position: relative; width: 100%; height: 100%; } #lee-content .footer .btn-group .button-one, #lee-content .footer .btn-group .button-two, #lee-content .footer .btn-group .button-block { position: absolute; height: 100%; text-align: center; color: #fff; cursor: pointer; } #lee-content .footer .btn-group .button-one { background: #3F474F; left: 0; right: 50%; } #lee-content .footer .btn-group .button-two { background: #596396; left: 50%; right: 0; } #lee-content .footer .btn-group .button-block { background: #596396; left: 0; right: 0; } /* input样式框 */ #lee-content .popup-input-wrap { margin-top: 15px; } #lee-content .popup-input-wrap .input-withdraw { margin: 0; padding: 0 10px; height: 30px; border: none; border-bottom: 1px solid #ccc; line-height: 30px; font-size: 16px; } #lee-content .input-extras { margin: 10px; text-align: right; font-size: 14px; color: #CDA; } .fadein { -webkit-animation: fadein 0.2s ease-in-out; animation: fadein 0.2s ease-in-out; } @keyframes fadein { 0% { opacity: 0; } 100% { opacity: 1; } } @-webkit-keyframes fadein { 0% { opacity: 0; } 100% { opacity: 1; } } .mask-fadein { -webkit-animation: mask-fadein 0.2s ease-in-out; animation: mask-fadein 0.2s ease-in-out; } @keyframes mask-fadein { 0% { opacity: 0; } 100% { opacity: 0.7; } } @-webkit-keyframes mask-fadein { 0% { opacity: 0; } 100% { opacity: 0.7; } } .fadeout { -webkit-animation: fadeout 0.2s ease-in-out; animation: fadeout 0.2s ease-in-out; } @keyframes fadeout { 0% { opacity: 1; } 100% { opacity: 0; } } @-webkit-keyframes fadeout { 0% { opacity: 1; } 100% { opacity: 0; } } .mask-fadeout { -webkit-animation: mask-fadeout 0.2s ease-in-out; animation: mask-fadeout 0.2s ease-in-out; } @keyframes mask-fadeout { 0% { opacity: 0.7; } 100% { opacity: 0; } } @-webkit-keyframes mask-fadeout { 0% { opacity: 0.7; } 100% { opacity: 0; } }

使用的方法:
var options = { width : 300, height : 170, title : { height : 40, content : "提示", color : "#5f5d5d", background : "#d1d1d1" }, main : { content : "", align : "left", background : "#ff979696", font : "1em", color : "#555" }, buttons : [{ name : "确定", background : "#c4e8da", color : "#26a65b", click : function(){ console.log("click")}, tap : function(){ console.log("tap") }, touchstart : function(){ return true}, touchend : function(){ return true;} },{ name : "取消", background : "#f6ccc2", color : "#d64541", click : function(){ return true; }, touchstart : function(){ return true;}, touchend : function(){ return true;} }] } document.getElementById("id1").addEventListener("tap", function(){ options.main.content = "<div class=‘popup-input-wrap‘>\ <input type=‘number‘ maxlength=‘20‘ placeholder=‘please enter your password‘ class=‘input-withdraw‘/> </div>"; options.buttons[0]["name"] = "按钮1"; options.buttons[0].click = function(){ // 此处写第一按钮需要处理的逻辑代码 }
options.buttons[1]["name"] = "按钮2"; options.buttons[1].click = function(){ // 此处写第二按钮需要处理的逻辑代码 } var pop = new Popup(options) pop.show(); // 弹出框按照需要手动设置显示 }) document.getElementById("id2").addEventListener("tap", function(){ options.main.content = "chasldkfjalskjdflk"
options.buttons[0]["name"] = "按钮1"; options.buttons[0].click = function(){ // 此处写第一按钮需要处理的逻辑代码 }
options.buttons[1]["name"] = "按钮2"; options.buttons[1].click = function(){ // 此处写第二按钮需要处理的逻辑代码 } var pop1 = new Popup(options) pop1.show(); })
内容区可以自定义一些html代码加上相关的css样式即可,菜鸟初次写插件,望大神指点。
PS: 此插件存在各种BUG,各种问题,请谨慎使用。
