ColorUI-UniApp navigation bar Back button to set a custom page

problem:

ColorUI-UniApp navigation bar to return only to go back, how to set a custom page?

Resolution:

1. Locate the navigation component cu-custom.vue under colorUi

2. Define a custom navigation attributes url

props: {
    // 定义一个导航url属性，如果有这个属性就使用这个跳转url
    url: {
        type: String,
        default: ''
    }
},

3. Modify the jump method

BackPage() {
    if (this.url) {
        uni.redirectTo({url: this.url})
    } else {
        if (getCurrentPages().length < 2 && 'undefined' !== typeof __wxConfig) {
            let url = '/' + __wxConfig.pages[0]
            return uni.redirectTo({
                url
            })
        }
        uni.navigateBack({
            delta: 1
        });
    }
}

4. How to pass url value it?

Such a jump from page to page b, c and then jump back to a page from b, b to c jump from the last page. If you do not set a custom url attribute, click c page return jump directly to a page, in order to solve this problem in the jump from b to c page when the page is passed to a relative path b c c page as the page jump back b to url to the page.

<navigator class="cu-item" navigateTo v-for="(user, index) in userData" :key="index" hover-class="none" 
            :url="jump(user)" open-type="redirect"></navigator >

// 跳转页面
jump: function(loan) {
    let data = {
        title: '用户详情',
        url: '../user/user-query' // 注意这个地址是a页面跳转到b（当前页）的相对地址
    }
    return this.contract(this.sonUrl, data)
}
