weex手机端安全键盘
2024-09-03 18:59:49
github地址：weexSafeKeyboard
效果图：
技术依赖：
框架：weex+vue
弹出层：weex-ui
图标：iconfont
说明：
1、如果不想用到weex-ui，可以把inputkey.vue文件里的wxc-popup组件去掉，按自己的弹窗实现即可；
2、删除、大小写、空格图标用的是iconfont;如不想用请自行替换;
本项目是放在本地，以安卓为例：android/app/src/main/assets/iconfont
3、密码可见、不可见图标按钮用的是common.js里的getImageUrl方法获取的路径，请自行替换
声明：
如有需要，请参考实现的思路，消化成自己的东西，勿直接复制，会消化不良。
实际调用页面：index.vue 代码如下：
<template>
<div>
<div class="cell">
<div class="cell_label">
<text class="label">密码</text>
</div>
<div class="cell_input">
<inputkey @inputVal="inputVal" :inputstyle="inputstyle" :textstyle="textstyle" type=true placeholder="请输入登录密码"></inputkey>
</div>
</div>
</div>
</template>
<style>
.cell {width: 750px;height: 120px;border-bottom-width: 2px;border-bottom-color: #C9C5C4;flex-direction: row;align-items: center;justify-content: center;}
.cell_label {justify-content: center;align-items: center;}
.label{font-size: 34px;font-weight: 600px;color:#000;}
.cell_input {justify-content: center;align-items: center;margin-left: 30px;}
</style>
<script>
import inputkey from './components/inputkey.vue';

组件：components/inputkey.vue 代码如下：

//获取图片完整路径前缀

var bundleUrl = this.bundleUrl(self);
var isHttp = bundleUrl.indexOf('http://') >= 0;
var imageUrl;

//vue语法中读取图片资源放在.bundle文件中
//不然会出现The requested URL was not found on this server.
imageUrl = bundleUrl.slice(0, i + 8) + '/images.bundle/';
}
}
return imageUrl;
}
//对象类型判断，下面深，浅拷贝用
//深浅拷贝来源百度，太懒没自己写
exports.util = (function () {
