一个基于weui的表单添加页
1、公众号页面跳转规则：
/*
* 公众号页面进入规则：
* 1.先请求接口获得一个URL
* 2.跳转请求的URL，腾讯会重定向到本地的页面
* 3.解析重定向的页面，获取code
* 4.传递code，获取到openid
* 5.openid是微信的唯一标识，拿到之后就可以请求自己的后台了（获取绑定用户列表、解绑、绑定等）
* */
2、上传附件的时候，是先上传保存到服务器拿到附件的id、src、name，直接根据sec显示，这里是转为base64显示的
/** * 上传附件 * 1、先使用base64显示 * 2、提交上传 * 3.保存表单 * */ function uploadAnyfilesFun() { var uploadFiles = document.querySelector('#upload_file'); uploadFiles.addEventListener('change', function () { var file = this.files[0]; // 图片上传后台 let formData = new FormData(); formData.append('file', file); $.ajax({ url: baseUrl+'/wechat/opinion/upload', type: 'POST', traditional: true, headers: {'token': Sessiontoken}, data: formData, processData: false, //tell jQuery not to process the data contentType: false, //tell jQuery not to set contentType success: function (data) { if (data.code != 0) { $.toast("上传附件失败", 'forbidden') return }else{ fileList.push(data.data) //实例化fileReader, let fd = new FileReader(); //获取当前选择文件的类型 let fileType = file.type; //调它的readAsDataURL并把原生File对象传给它， fd.readAsDataURL(file);//base64 // base64显示图片 fd.onload = function(){ if(/^image\/[jpeg|png|jpg|gif]/.test(fileType)){ let s = Date.parse(new Date()) let h = '<span>' + '<img onclick="imgsAction(this,\''+data.data.id+'\')" src="'+this.result+'" alt="">' + '</span>' $(".imgsDemo").append(h) } } } } }); }, false); }
3、一个小知识点：数组中，根据索引删除数组中的元素
Array.prototype.delete=function(delIndex){ var temArray=[]; for(var i=0;i<this.length;i++){ if(i!=delIndex){ temArray.push(this[i]); } } return temArray; }
// 删除保存的文件 let d = fileList.findIndex((item,index)=>{ return item.id === s }) fileList = fileList.delete(d)
