验签成功 增加

that.$wx.ready(res => {

console.log(res);

that.$nextTick(() => {

let btn = document.getElementById('launch-btn');

btn.addEventListener('launch', e => {

console.log('success');

alert('success');

});

btn.addEventListener('error', e => {

alert('小程序打开失败');

console.log('fail', e.detail);

alert('fail', e.detail);

});

});

});

回调函数

handleError(e) {

console.log('fail', e.detail);

alert('fail', e.detail);

},

handleLaunchFn(e) {

console.log('success');

alert('success');

},

handletest() {

console.log('handletest');

alert('handletest');

}
