在開(kāi)發(fā)小程序過(guò)程中，相信有一部分人，遇到過(guò)一個(gè)問(wèn)題：當(dāng)使用tabBar跳轉(zhuǎn)頁(yè)面時(shí)，所跳轉(zhuǎn)的頁(yè)面下方必定有 tabBar顯示，而當(dāng)你需要把它隱藏時(shí)，卻束手無(wú)策。話不多說(shuō)，在這里給大家分享如何隱藏tabBar的方法。

方法一:自定義tabBar

使用自定義tabBar，新建一個(gè)tarBar.wxml模板頁(yè)，然后引用模板的頁(yè)面?zhèn)魅霐?shù)據(jù)即可，代碼如下：

<template name="tabBar">  
  <view class="flex-h" style="color: {{tabBar.color}}; background: {{tabBar.backgroundColor}}; {{tabBar.position=='top'? 'top: 0' : 'bottom: 0'}}; {{tabBar.borderStyle? (tabBar.position=='top'? 'border-bottom: solid 1px '+tabBar.borderStyle + ';' : 'border-top: solid 1px '+tabBar.borderStyle + ';') : ''}}">  
  <block wx:for="{{tabBar.list}}" wx:key="pagePath">  
    <navigator url="{{item.pagePath}}" open-type="{{item.pageTum}}" class="menu-item" style="{{item.active? 'color: '+(item.selectedColor? item.selectedColor : tabBar.selectedColor) : ''}}">  
      <image src="{{item.selectedIconPath}}" wx:if="{{item.active}}"></image>  
      <image src="{{item.iconPath}}" wx:if="{{!item.active}}"></image>  
      <text>{{item.text}}</text>  
    </navigator>  
    </block>  
  </view>  
</template>

接下來(lái)是在index.js的配置對(duì)象：

tabBar:{
    "color": "#9E9E9E",
    "selectedColor": "#f00",
    "backgroundColor": "#fff",
    "borderStyle": "#ccc",
    "list":[{
            "pagePath": "/pages/index/index",
            "text": "主頁(yè)",
            "iconPath": "../../images/index.png",
            "selectedIconPath": "../../images/index_active.png",
            "pageTum": "redirect",
            "selectedColor": "#4EDF80",
            active: true
            },
            {
            "pagePath": "/pages/tum/tum",
            "text": "其他",
            "iconPath": "../../images/pageTum.png",
            "pageTum": "navigate",
            "selectedColor": "#4EDF80",
            active: false
            },
            {
            "pagePath": "/pages/mine/mine",
            "text": "我的",
            "iconPath": "../../images/mine.png",
            "selectedIconPath": "../../images/mine_active.png",
            "pageTum": "redirect",
            "selectedColor": "#4EDF80",
            active: false
            }],
            "position": "bottom"
    }
}

在這里要注意的是，active表示該頁(yè)面是否被選中，pageTum表示點(diǎn)擊該頁(yè)面跳轉(zhuǎn)方式，‘其他’這個(gè)頁(yè)面不用設(shè)置tabBar，并且它的pageTum的值是navigate，表示點(diǎn)擊‘其他’跳轉(zhuǎn)的頁(yè)面就不會(huì)顯示tabBar。

index.wxml引入模板：

<import src="../template/tabBar.wxml" />  
<template is="tabBar" data="{{tabBar: tabBar}}" /> 
<text>主頁(yè)面</text>    //顯示內(nèi)容

然后在mine頁(yè)面也一樣配置數(shù)據(jù)把a(bǔ)ctive的值改為true，引入模板。效果如下：

"tabBar": {
        "color": "#9E9E9E",
        "selectedColor": "#f00",
        "backgroundColor": "#fff",
        "borderStyle": "#ccc",
        "list": [{
                "pagePath": "pages/index/index",
                "text": "主頁(yè)",
                "iconPath": "images/index.png",
                "selectedIconPath": "images/index_active.png"
            },
            {
                "pagePath": "pages/tum/pageTum",
                "text": "其他",
                "iconPath": "images/pageTum.png"
            },
            {
                "pagePath": "pages/mine/mine",
                "text": "我的",
                "iconPath": "images/mine.png",
                "selectedIconPath": "images/mine_active.png"
            }
        ]
    }

data: {
        num: 0,
    },
    onLoad: function() {},
    onShow: function() {
        this.data.num++;
        if (this.data.num % 2 == 0) {
            wx.switchTab({
                url: '../index/index'
            });
        } else {
            wx.navigateTo({
                url: './tum'
            })
        }
    }
