如何將多個變量組合在一起，使其行爲相同？

Question

我有我想要當你徘徊它們中的任何一個發生在所有3個不同元素的影響，但我有麻煩分組變量在一起，使他們都可以採取同樣

我寫的代碼是我認爲會將他們分組在一起。

var germany=new Array(); 
    germany[0]=germany1_poly;  
    germany[1]=germany2_poly; 
    germany[2]=germany3_poly; 


google.maps.event.addListener(germany, "mouseover",function() { 
    germany.setOptions({ fillColor: "#ff0000", strokeColor: "#ff0000" }); 
}); 

Answer 1

var i; 
for(i = 0; i < germany.length; i++){ 
    google.maps.event.addListener(germany[i], "mouseover",function() { 
     germany.setOptions({ fillColor: "#ff0000", strokeColor: "#ff0000" }); 
    }); 
} 

Answer 2

如果我讀你的問題正確，您希望在其中任何一個觀察到鼠標懸停更新所有三個領域。 下面是一些應該幫助的咖啡腳本，下面是相應的javascript。

的CoffeeScript：

germany = [ 
    germany1_poly  
    germany2_poly 
    germany3_poly 
] 

areas_effect = (areas) -> 
    for area in areas 
    area.setOptions({ fillColor: "#ff0000", strokeColor: "#ff0000" }) 

areas_observer = (areas) -> 
    for area in areas 
    google.maps.event.addListener(area, "mouseover", areas_effect(areas)) 

areas_observer(germany) 

javascipt的：

var areas_effect, areas_observer, germany; 
germany = [germany1_poly, germany2_poly, germany3_poly]; 
areas_effect = function(areas) { 
    var area, _i, _len, _results; 
    _results = []; 
    for (_i = 0, _len = areas.length; _i < _len; _i++) { 
    area = areas[_i]; 
    _results.push(area.setOptions({ 
     fillColor: "#ff0000", 
     strokeColor: "#ff0000" 
    })); 
    } 
    return _results; 
}; 
areas_observer = function(areas) { 
    var area, _i, _len, _results; 
    _results = []; 
    for (_i = 0, _len = areas.length; _i < _len; _i++) { 
    area = areas[_i]; 
    _results.push(google.maps.event.addListener(area, "mouseover", areas_effect(areas))); 
    } 
    return _results; 
}; 
areas_observer(germany);
