</template><script>
export default {name: 'aweakAppByWeChat',props: {btnStyle: String, // 自定義按鈕樣式 `.btnClass{xx}`btnName: {type: String,default: '立即打開' // 自定義按鈕名稱}},data() {return {wxAppId: '',targetInfo: null, // 傳遞參數，格式需為字符串};},methods: {// wx 喚起失敗異常處理, 降級處理跳轉onListenLaunchError(e) {console.log('wx喚醒失敗 | error', e.detail || e);this.$emit('launchError');}}
};
</script><style lang="less" scoped>
#launch-btn {position: absolute;top: 0;left: 0;right: 0;bottom: 0;opacity: 0;width: 100%;height: 100%;z-index: 99999;
