mychromeextension's Issues

getEventListeners

getEventListeners 无法在 JS 中使用

var是全局作用域 let 只在当前代码块内有效

鼠标悬停显示源码

window.document.body.onmouseover = function(event){
  var event_target = event.target;
  //console.log('onmouseover : ' + event_target);
  if(event_target['title'] === null || event_target['title'] === ''){
    event_target['title'] = 'onmouseover : ' + event_target.innerHTML.replace(' ', '');
  }
  else if(event_target['title'] !== null && event_target['title'].indexOf('onmouseover : ') === -1){
    event_target['title'] += "\r\n\r\n" + 'onmouseover : ' + event_target.innerHTML.replace(' ', '');
  }
}

使用 chrome.storage.sync，保存和同步用户的插件设置

var my_chrome_extension_js_settings = {};

var my_show_storage_usage = function () {
    chrome.storage.sync.getBytesInUse(null, function(data) {
        console.log('MyChromeExtension storage sync usage: ' + data + ' Bytes');
    });
    chrome.storage.sync.get(null, function(data) {
        console.log('MyChromeExtension storage sync load: ' + JSON.stringify(data));
        my_chrome_extension_js_settings = data;
        localStorage.setItem('my_chrome_extension_js_settings', JSON.stringify(my_chrome_extension_js_settings));
    });
};
var my_clear_storage_usage = function () {
    chrome.storage.sync.clear();
};
my_show_storage_usage();

var my_set_js_setting = function (key, value) {
    var js_setting = {};
    js_setting[key] = value;
    var js_file = my_get_loaded_js();
    var data = {};
    data[js_file] = js_setting;
    my_chrome_extension_js_settings[js_file] = js_setting;
    localStorage.setItem('my_chrome_extension_js_settings', JSON.stringify(my_chrome_extension_js_settings));
    chrome.storage.sync.set(data, function() {
        console.log('MyChromeExtension storage sync set ok: ' + JSON.stringify(data));
    });
    console.log('MyChromeExtension my_set_js_setting: ' + JSON.stringify(data));
};

var my_get_js_setting = function (key) {
    chrome.storage.sync.get(null, function(data) {
        console.log('MyChromeExtension storage sync get ok: ' + JSON.stringify(data));
        my_chrome_extension_js_settings = data;
        localStorage.setItem('my_chrome_extension_js_settings', JSON.stringify(my_chrome_extension_js_settings));
    });
    var value = undefined;
    var js_file = my_get_loaded_js();
    var js_setting = my_chrome_extension_js_settings[js_file];
    if(js_setting && js_setting[key]){
        value = js_setting[key];
    }
    else {
        var tmp_settings = JSON.parse(localStorage.getItem('my_chrome_extension_js_settings'));
        if(tmp_settings && tmp_settings[js_file] && tmp_settings[js_file][key]){
            value = tmp_settings[js_file][key];
        }
    }
    var data = {};
    data[key] = value;
    console.log('MyChromeExtension my_get_js_setting: ' + JSON.stringify(data));
    return value;
};

chrome.storage.onChanged.addListener(function(changes, areaName){
    console.log('MyChromeExtension storage ' + areaName + ' changed: ' + JSON.stringify(changes));
    // {"chrome-extension://iklbhcbmbooeeckkjljbmoekngggplbd/site/all.js":{"newValue":{"MyChromeExtension":"MyChromeExtension"}}}
    // {"chrome-extension://iklbhcbmbooeeckkjljbmoekngggplbd/site/all.js":{"oldValue":{"MyChromeExtension":"MyChromeExtension"}}}
});
