uniapp自带的提示框不符合我们的要求，需要自己写一个提示框，且全局通用。
解决思路:
使用 plus.nativeObj 来绘制窗口以及事件监听。 官方文档
方法如下：
1. 首先创建一个整个屏幕的控件，作为一个父容器。
此时还看不到任何东西
let screenHeight = uni.getSystemInfoSync().screenHeight; let style = { width:'100%', height: (screenHeight + 'px'), left:'0px', top:'0px' }; // 创建原生控件对象 // 参数1: id // 参数2: 控件的样式 let view = new plus.nativeObj.View('showModalView',style);
2. 绘制遮罩层
view.draw([ {tag:'rect',id:'modal',color:`rgba(0,0,0,0.4)`,position:{top:'0px',left:'0px',width:'100%',height:'100%'}} ]); { tag:'rect', // 绘制矩形 id:'modal', // 控件id color:`rgba(0,0,0,0.4)`, // 背景色 position:{top:'0px',left:'0px',width:'100%',height:'100%'} // 位置和大小样式 }
view.draw(tags); 在控件上绘制，传入绘制对象。
绘制对象文档可绘制图片、矩形区域、文本等内容。
3.绘制通知框样式
view.draw([ {tag:'rect',id:'modal',color:`rgba(0,0,0,0.4)`,position:{top:'0px',left:'0px',width:'100%',height:'100%'}}, {tag:'rect',id:'content',rectStyles:{borderWidth:'2px',radius:'8px',color:`rgba(36,34,56,1)`},position:{top:startTop+'px',left:startLeft+'px',width:width+'px',height:height+'px'}}, ]); { tag:'rect', id:'content', // 矩形的样式 rectStyles:{borderWidth:'2px',radius:'8px',color:`rgba(36,34,56,1)`}, // 位置和大小. 下面的变量是根据屏幕宽高手动计算的 position:{top:startTop+'px',left:startLeft+'px',width:width+'px',height:height+'px'} } interface RectStyles { attribute String color; attribute String radius; attribute String borderColor; attribute String borderWidth; }
4. 绘制标题和内容
view.draw([ {tag:'rect',id:'modal',color:`rgba(0,0,0,0.4)`,position:{top:'0px',left:'0px',width:'100%',height:'100%'}}, {tag:'rect',id:'content',rectStyles:{borderWidth:'2px',radius:'8px',color:`rgba(36,34,56,1)`},position:{top:startTop+'px',left:startLeft+'px',width:width+'px',height:height+'px'}}, {tag:'font',id:'title',text:modelInfo.tit,textStyles:{size:'16px',color:'#fff'},position:{top:titleTop+'px',left:startLeft+'px',width:width+'px',height:titleHeight+'px'}}, {tag:'font',id:'text',text:modelInfo.content,textStyles:{size:'14px',color:'#fff',whiteSpace:'normal',align:modelInfo.align},position:{top:contentTop+'px',left:startLeft+'px',width:width+'px',height:contentHeight+'px'}}, // 这个是内容和底部按钮的分割线 {tag:'rect',id:'line',color:'rgba(255,255,255,0.3)',position:{top:lineTop+'px',left:startLeft+'px',width:width+'px',height:'0.5px'}}, ]); { tag:'font', // 绘制文字 id:'title', text:modelInfo.tit, // 文字内容 textStyles:{size:'16px',color:'#fff'}, position:{top:titleTop+'px',left:startLeft+'px',width:width+'px',height:titleHeight+'px'} },
5. 创建确认按钮控件
我们需要给确认按钮设置点击事件，所以它要作为一个新的控件，而不是再刚刚的控件上继续绘制。
// 确认 let viewconfirm=new plus.nativeObj.View('confirm', { width:modelInfo.delCancel?width+'px':'40%', height:buttonHeight+'px', top:lineTop+'px', left:modelInfo.delCancel?startLeft+'px':halfWidthForGlobal +'px', backgroundColor:'rgba(255,255,255,0)', }, ); viewconfirm.draw([ {tag:'font',id:'confirm',text:modelInfo.confirmVal,textStyles:{color:modelInfo.confirmColor,size:'14px'}}, ]);
设置点击事件
viewconfirm.addEventListener("click",(e)=>{ // 发送事件 this.$event({res:true,types:'confirm'}); // 隐藏当前控件(关闭) this.hide(); },false);
将 viewconfirm和view显示出来:
function show(){ this.view.show(); this.confirmModel.show(); }
下面就是将这些挂载到Uni上就可以了。
下面是项目中的完整代码:
index.js 用于绘制
// show_modal/index.js export class show_model{ constructor(option={}) { this.bodyModel=null; this.cancelModel=null; this.confirmModel=null; this.pageHeight=uni.getSystemInfoSync().screenHeight; this.pageWidth = uni.getSystemInfoSync().screenWidth;

let backOff=option.backOff||false; //#ifdef APP-PLUS this.creatView({height:`${this.pageHeight}px`,top:0},opacity,clickEvent,{'tit':model_tit,'content':model_content,cancelVal,confirmVal,confirmColor,cancelColor,delCancel,align}) if(!backOff){ this.backbtn(); } //#endif } backbtn(){ let that=this; plus.key.addEventListener('backbutton', function (e) { that.hide(); },false) } //生成提示框view creatView(style,opa,clickEvent,modelInfo){ style = { left:'0px', width:'100%', ...style } let platform = plus.os.name.toLowerCase();

}else{ view.draw([ {tag:'rect',id:'modal',color:`rgba(0,0,0,${opa})`,position:{top:'0px',left:'0px',width:'100%',height:'100%'}}, {tag:'rect',id:'content',rectStyles:{borderWidth:'2px',radius:'8px',color:`rgba(36,34,56,1)`},position:{top:startTop+'px',left:startLeft+'px',width:width+'px',height:height+'px'}}, {tag:'font',id:'title',text:modelInfo.tit,textStyles:{size:'16px',color:'#fff'},position:{top:titleTop+'px',left:startLeft+'px',width:width+'px',height:titleHeight+'px'}}, {tag:'font',id:'text',text:modelInfo.content,textStyles:{size:'14px',color:'#fff',whiteSpace:'normal',align:modelInfo.align},position:{top:contentTop+'px',left:startLeft+'px',width:width+'px',height:contentHeight+'px'}}, {tag:'rect',id:'line',color:'rgba(255,255,255,0.3)',position:{top:lineTop+'px',left:startLeft+'px',width:width+'px',height:'0.5px'}}, {tag:'rect',id:'line2',color:'rgba(255,255,255,0.3)',position:{top:lineTop+'px',left:halfWidthForGlobal+'px',width:modelInfo.delCancel?'0px':'0.5px',height:modelInfo.delCancel?'0px':buttonHeight+'px'}} ]); } var num = 0.55; if(platform == "ios"){ num = 0.57 } if(!modelInfo.delCancel){ // 取消 let viewCancel=new plus.nativeObj.View('cancel',{width:halfWidth+'px',height:buttonHeight+'px',top:lineTop+'px',left:startLeft+'px',backgroundColor:'rgba(255,255,255,0)'});

this.hide(); },false); //点击蒙布 if(clickEvent){ view.addEventListener("click", (e) => { this.$event({res:false,types:'cover'}); this.hide(); }, false); } this.bodyModel=view; this.confirmModel=viewconfirm; } showModalAnimationClose(){ var options = {type:'pop-out',duration:300}; plus.nativeObj.View.startAnimation(options,{view:this.bodyModel},{view:this.cancelModel},{view:this.viewconfirm},function(){ console.log('plus.nativeObj.View.startAnimation动画结束'); // 关闭原生动画 plus.nativeObj.View.clearAnimation(); }); } showModalAnimationOpen(){ var options = {type:'pop-in',duration:1000}; plus.nativeObj.View.startAnimation(options,{view:this.bodyModel},{view:this.cancelModel},{view:this.viewconfirm},function(){ console.log('plus.nativeObj.View.startAnimation动画结束'); // 关闭原生动画 plus.nativeObj.View.clearAnimation(); }); } show(){ this.showModalAnimationOpen(); this.bodyModel.show(); if(this.cancelModel){ this.cancelModel.show(); } this.confirmModel.show(); } hide(){ this.showModalAnimationClose(); this.bodyModel.hide(); if(this.cancelModel){ this.cancelModel.hide(); } this.confirmModel.hide(); } } export default show_model
show_modal.js: 用于创建promise对象并挂载
// show_modal/xt_show_modal.js import show_modal from './index.js' const xt_show_modal = { install: function(Vue) { const show_modal_fun=function(op={}){ //#ifdef APP-PLUS return new Promise((resolve, reject)=>{ let ssm=new show_modal({ ...op, $event:function(e){ if(e.res){ resolve(e); }else{ reject(e); } } })； ssm.show(); Vue.prototype.$hide=function(){ ssm.hide(); } }) //#endif // 适应H5 //#ifdef H5 var promise=uni.showModal({ title: op.title, content: op.content, showCancel: !op.delCancel, cancelText: op.cancelVal, confirmText: op.confirmVal, }); return new Promise((resolve,reject)=>{ promise.then(data=>{ var [err, res] = data; if(res.confirm){ resolve() }else{ reject(); } }) }) //#endif } // $showModal挂载到uni对象上 uni.$showModal = show_modal_fun Vue.prototype.$showModal = show_modal_fun } }; export default xt_show_modal;
main.js中挂载
// 自定义showModal组件 import xt_show_modal from '@/component/show_modal/xt_show_modal.js' Vue.use(xt_show_modal);
使用:
// showModel的使用 uni.$showModal({ title:"", //可选,不填则不显示 content:'未知错误，请联系管理员！', delCancel: true, confirmVal: '知道了', // 可选 cancelVal:'取消', // 可选 }).then(res=>{ // 点击确认按钮点击事件 }).catch(res=>{ // 点击取消按钮点击事件 });
