HTML5 / JS存储事件处理程序 [英] HTML5 / JS storage event handler

问题描述

我正在使用safari webkit的引擎与HTML5和JS一起创建一个离线应用程序现在我正在使用sessionStorage数组来存储我的应用程序的状态（模拟）。

I'm using safari webkit's engine together with HTML5 and JS to create an offline application now I'm using the sessionStorage array to store status of my application(simulation).

存储数据与检查员工作正常，函数工作正常，事件处理程序没有响应

the storage data works fine with the inspector the functions work fine it's the event handler that isn't responding

测试预成型由 Anurag 在 http://jsfiddle.net/pvRgH/ 在这里也不工作

the test preformd by Anurag at http://jsfiddle.net/pvRgH/ also doesn't work here

window.addEventListener('storage', storageEventHandler, false);
function storageEventHandler(evt){
    alert("storage event called key: " + evt.key );
    switch(evt.key){
        case 'bat1':
        case 'bat2': batteryDCMeter(); break;
        case 'extPowerOn': rechargeBattery(); break;
    }   
}

function load()
{
    dashcode.setupParts();
    //set HTML 5 key/value's
    sessionStorage.setItem('bat1', 'OFF');
    sessionStorage.setItem('bat2', 'OFF');
    sessionStorage.setItem('bat1DC', '26.2');
    sessionStorage.setItem('bat2DC', '26.2');
}

function bat1OnOff(event)
{
    if(sessionStorage['bat1'] == 'OFF'){
        sessionStorage['bat1'] = 'ON';
    }else{
        sessionStorage['bat1'] = "OFF";
    }
}


function bat2OnOff(event)
{
    if(sessionStorage['bat2'] == 'OFF'){
        sessionStorage['bat2'] = 'ON';
    }else{
        sessionStorage['bat2'] = "OFF";
    }
}

推荐答案

存储事件处理程序只有在从另一个窗口触发存储事件时才会触发。

Storage event handlers only fire if the storage event is triggered from another window.

如何在Safari 5 +中更新localStorage时如何触发事件？
