  • ionic中的生命周期函数

    //ionic中的生命周期函数
    onPageLoaded(){ //page初始化时
    console.log("page 1 : page loaded");
    }
    //在这里可以做页面初始化的一些事情
    onPageWillEnter(){ //page即将进入时
    console.log("page 1 : page will enter");
    }
    onPageDidEnter(){ //page进入后
    console.log("page 1 : page did enter");
    }
    onPageWillLeave(){ //page即将离开
    console.log("page 1 : page will leave");
    }
    onPageDidLeave(){ //page离开后
    console.log("page 1 : page did leave");
    }
    onPageWillUnload(){
    //从DOM中移除时候执行的生命周期,不常用
    console.log("")
    }
    onPageDidUnload(){
    //DOM中移除执行完成的时候,不常用
    }

    ionic v2中新的周期函数

    Page EventDescription
    ionViewLoaded Runs when the page has loaded. This event only happens once per page being created and added to the DOM. If a page leaves but is cached, then this event will not fire again on a subsequent viewing. The ionViewLoaded event is good place to put your setup code for the page.
    ionViewWillEnter Runs when the page is about to enter and become the active page.
    ionViewDidEnter Runs when the page has fully entered and is now the active page. This event will fire, whether it was the first load or a cached page.
    ionViewWillLeave Runs when the page is about to leave and no longer be the active page.
    ionViewDidLeave Runs when the page has finished leaving and is no longer the active page.
    ionViewWillUnload Runs when the page is about to be destroyed and have its elements removed.
    ionViewDidUnload Runs after the page has been destroyed and its elements have been removed.
