uni-app解决在qq和微信浏览器两个标题情况

在main.js中配置以下代码就可以解决

Vue.mixin({
	mounted() {
		// #ifdef H5
		if (this.isWeiXinBrowser() || this.isQQBrowser()) {
			this.navTitle()
		}
		// #endif
	},
	methods: {
		// #ifdef H5
		isWeiXinBrowser() {
			let ua = navigator.userAgent.toLowerCase()
			return ua.indexOf('micromessenger') != -1
		},
		isQQBrowser() {
			var ua = navigator.userAgent.toLowerCase()
			if (ua.match(/QQ/i) == "qq") {
				return true
			} else {
				return false
			}
		},
		// #endif
		navTitle() {
			this.$nextTick(() => {
				let navTitleDom = document.getElementsByTagName('uni-page-head')
				if (navTitleDom.length) {
					navTitleDom[0].style.display = 'none'
				}
			})
		}
	}
})
