var editor;
$(function(){
   editor = ace.edit('editor');
});

这种参数必须在$(document) 里面调用不能直接调

普通授权 用wx.authorize 就可以了有相关文档 可以直接用
https://developers.weixin.qq.com/miniprogram/dev/api/authorize.html
但是用户信息授权被坑爹的小程序改成了只能用button调起

1

<button open-type="getUserInfo" bindgetuserinfo="userInfoHandler"> Click me </button>

用以下代码去判断用户是否授权了

1
2
3

userInfoHandler: function (e) {
  e.detail.userInfo; //要判断这个，有值表示用户点击允许，没有则表示用户点击的是拒绝。
}

后台只能获取到当前用户信息 并获取不到其他用户信息！！！！坑爹！！！ 只能暂存

在 didFinishLaunchingWithOptions方法中调用就可以了

window.alert = function(name){
var iframe = document.createElement(“IFRAME”);
iframe.style.display=”none”;
iframe.setAttribute(“src”, ‘data:text/plain,’);
document.documentElement.appendChild(iframe);
window.frames[0].window.alert(name);
iframe.parentNode.removeChild(iframe);
};

window.confirm = (message) ->
iframe = document.createElement(‘IFRAME’)
iframe.style.display = ‘none’
iframe.setAttribute ‘src’, ‘data:text/plain,’
document.documentElement.appendChild iframe
alertFrame = window.frames[0]
result = alertFrame.window.confirm(message)
iframe.parentNode.removeChild iframe
result

$(‘.notifyjs-wrapper’).remove();
