最近用angular做微信的分享，发现动态去赋值分享接口的title desc都不管用 后来百度了一下，微信分享的title会读取html里<title></title>里的内容，而我在title里写了{{title}},所以每次分享 分享的标题都是{{title}}，解决方法是

//设置页面标题
document.title=$scope.title;
//增加页面元素变动，从而保证标题一定会刷新//解决问题：由于部分手机浏览器bug，导致标题更新后不会自动刷新var $body = $('body');var $iframe = $("<iframe style='display:none;' src='/favicon.ico'></iframe>");$iframe.on('load',function() {    setTimeout(function() {        $iframe.off('load').remove();    }, 0);}).appendTo($body);

我的代码是：

wx.ready(function () {
    wx.onMenuShareAppMessage({
        title:$scope.title,
        desc: $scope.desc,
        link:$scope.link,
        imgUrl:$scope.imgUrl,
        success: function (res) {
            alert('已分享');
            $scope.isShare=false;
            $scope.$apply()

        },
        cancel: function (res) {
            alert('已取消');
            $scope.isShare=false;
            $scope.$apply()
        },
        fail: function (res) {
            $scope.isShare=false;
            $scope.$apply()
        }
    });

我猜测在调用分享接口时并没有读取到$scope.title $scope.desc等数据，

后来我就把微信的配置和分享封装到一个方法中，然后把分享需要的参数作为方法的参数传入，这样在调用风险方法时就可以百分百保证数据是成功读取到的

$scope.wechat=function(title,desc,link,imgUrl){
    var ua = window.navigator.userAgent.toLowerCase();
    if(ua.match(/MicroMessenger/i) == 'micromessenger'){
        var timestamp=Math.round(new Date().getTime()/1000);
        var url=window.location.href;
        var noncestr="dianjingwang";
        var signature='',appId="";
        $.ajax({
            type: 'POST',
            url: '/wx/sign.json',
            data: {timestamp:timestamp,url:url,noncestr:noncestr},
            dataType: 'json',
            async :false,  //默认为true 异步
            success:function(data){
                if(data.msg="success"){
                    appId=data.ret;
                    signature=data.value;
                }
            }
        });

这样就完美的解决了这个问题。记录一下。
