uniapp webview页面从组件页面回退时不刷新解决办法

本文介绍: 初次进入页面时只有on load 执行，不需要 onshow 执行所以加了uni.getSt ora geSync()来限制 onshow 执行。后面返回时只有onshow会执行，由于地址相同页面可能不会刷新，加入index使地址发生变化。

&lt;template&gt;
		  &lt;!-- 事件处理 --&gt;
	  &lt;web-view v-if="url.length&gt;0" :src="url" &gt;&lt;/web-view&gt;
</template>

<script>
var _self;	
	import {mapState,mapMutations} from 'vuex'	
    export default {
        data() {
            return {
				url:'/hybrid/html/pages/work/problemHandle/problemHandle.html',
				index:0,
            }
        },
		computed: mapState(['forcedLogin','username','token']),
		onLoad() {
            _self = this;
			let userpass = uni.getStorageSync("userpass");
			
			this.url = `/hybrid/html/pages/work/problemHandle/problemHandle.html?token=${this.token}&amp;realname=${encodeURI(encodeURI(userpass.userInfo.realname))}&amp;rolename=${encodeURI(encodeURI(userpass.role[0].role_name))}`
		},
		onShow(el) {//页面打开
			let allObj = uni.getStorageSync("uni_allTemporary_onShow_Updata");
			let userpass = uni.getStorageSync("userpass");
			if (JSON.stringify(allObj) != '{}') {
				//更新页面
				_self.url = '';
				setTimeout(() => {
					_self.index = (_self.index + 1);
					_self.url = `/hybrid/html/pages/work/problemHandle/problemHandle.html?index=${_self.index}&amp;realname=${encodeURI(encodeURI(userpass.userInfo.realname))}&amp;rolename=${encodeURI(encodeURI(userpass.role[0].role_name))}&amp;token=${_self.token}`;
				}, 500);
				uni.setStorageSync("uni_allTemporary_onShow_Updata",{});
			}
			uni.setStorageSync("uni_allTemporary_onShow_Updata",{});
