折腾:

【已解决】ReactJS中如何实现长按某行显示内容

期间,去解决了:

【已解决】react-tappable中TappableMixin.js报错:Uncaught TypeError this.setState is not a function

但是:

用代码:

    makeActive: function makeActive() {
        if (!this.isMounted()) return;
        this.clearActiveTimeout();
        this.setState({
            isActive: true
        });
    }.bind(this),

结果报错:

TappableMixin.js?81b1:90 Uncaught TypeError: this.isMounted is not a function
    at Object.makeActive (eval at 977 (0.6291309….hot-update.js:7), <anonymous>:90:13)
    at Object.onTouchStart (eval at 977 (0.6291309….hot-update.js:7), <anonymous>:82:10)
    at HTMLSpanElement.eventProxy (eval at <anonymous> (bundle.js:765), <anonymous>:96:32)

this.isMounted is not a function

react-tappable  this.isMounted is not a function

this.isMounted is not a function

ajax – this.IsMounted() is not a function – Stack Overflow

isMounted is an Antipattern – React Blog

react js long press

isMounted is deprecated · Issue #105 · JedWatson/react-tappable

-》

中写的是:已经在这个commit中解决了此问题了:

Fix `isMounted` deprecation · matthieuprat/react-tappable@5e583e1

但是看到其写法,和我刚才试的类似

    componentWillUnmount: function componentWillUnmount() {
        this.isMounted = false;
        // this.mounted = false;
        // mounted = false;
        // this.setState({isMounted : false});
        // this.state.isMounted = false;
        this.cleanupScrollDetection();
        this.cancelPressDetection();
        this.clearActiveTimeout();
        // console.log(`componentWillUnmount this.state.isMounted=${this.state.isMounted}`);
    //}.bind(this),
    },
    componentDidMount: function() {
        this.isMounted = true;
    },
    // componentDidMount: function componentDidMount() {
    //     // this.mounted = true;
    //     mounted = true;
    //     // this.setState({isMounted : true});
    //     // console.log(`componentDidMount this.isMounted=${this.isMounted}`);
    //     // console.log(`makeActive this.state.isMounted=${this.state.isMounted}`);
    // // }.bind(this),
    // },
    makeActive: function makeActive() {
        // if (!this.isMounted()) return;
        //if (!this.isMounted().bind(this)) return;
        // console.log(`makeActive this.state.isMounted=${this.state.isMounted}`);
        // if (!this.state.isMounted) return;
        // console.log(`makeActive this.mounted=${this.mounted}`);
        // console.log(`makeActive mounted=${mounted}`);
        // if (!this.mounted) return;
        // if (!mounted) return;
        console.log(`makeActive this.isMounted=${this.isMounted}`);
        if (!this.isMounted) return;
        this.clearActiveTimeout();
        // clearActiveTimeout();
        this.setState({
            isActive: true
        });
    // }.bind(this),
    },

-》但是虽然没有警告了,但是onPress感觉没有生效啊

-》我的函数handlePressEvent还是没有被调用啊。
