如何從另一個功能改變按鈕？

Question

var ButtonFarmAtivada = new Array(); 

function X() { 
var tableCol = dom.cn("td"); //cell 0 

//create start checkbox button 

ButtonFarmAtivada[index] = createInputButton("checkbox", index); 

ButtonFarmAtivada[index].name = "buttonFarmAtivada_"+index; 

ButtonFarmAtivada[index].checked = GM_getValue("farmAtivada_"+index, true); 

FM_log(3,"checkboxFarm "+(index)+" = "+GM_getValue("farmAtivada_"+index)); 

ButtonFarmAtivada[index].addEventListener("click", function() { 
     rp_farmAtivada(index); 
}, false); 

tableCol.appendChild(ButtonFarmAtivada[i]); 

tableRow.appendChild(tableCol); // add the cell 

} 

1）是否有可能創建一個數組中的按鈕，因爲我試圖在該示例中做？像一排按鈕？

2）我問，因爲我將不得不從另一個函數來更改此按鈕，我想是這樣做的（不工作）：

function rp_marcadesmarcaFarm(valor) { 

    var vListID = getAllVillageId().toString(); 

    FM_log(4,"MarcaDesmarcaFarm + vListID="+vListID); 

    var attackList = vListID.split(","); 

    for (i = 0; i <= attackList.length; i++) { 
     FM_log(3, "Marca/desmarca = "+i+" "+buttonFarmAtivada[i].Checked); 
     ButtonFarmAtivada[i].Checked = valor; 
    }; 
};

對於1號）是，您可以。

function createInputButton(type, index) { // um, why the 'index' param? 
    // also, why is this function called 'createInputButton' 
    // if sometimes it returns a checkbox as opposed to a button? 
    var inputButton = document.createElement("input"); 
    inputButton.type = type; // alternately you could use setAttribute like so: 
          // inputButton.setAttribute("type", type); 
          // it would be more XHTML-ish, ♪ if that's what you're into ♫ 
    return inputButton; 
} 

我真的不明白第2部分，對不起。
