Firefox兼容性問題

1、firefox不支持innerText，outerText，outerHTML

解決思路：a）用innerHTML替換innerText

    b）爲Firefox擴展innerText屬性，詳細參考：Firefox 不支持 DOM 對象的 outerHTML、innerText、outerText 屬性（http://www.w3help.org/zh-cn/causes/SD9017）

2、firefox不支持onfocusin，onfocusout

參考：http://help.dottoro.com/ljggspvo.php

Instead of onfocus rather use onfocusin, that'll make your code to work. EDIT I just realized, that there is no focusin in Firefox. Hence you need something heavier. The script: function changeValueOnFocus (e, elm) { elm = elm || this; elm.value = 1234; return; } window.onload = function () { if (window.onfocusin === undefined) { document.getElementById('someinput').addEventListener('focus', changeValueOnFocus, false); } return; } and for input you'll need an id: <input id="someinput" maxlength="5" onfocusin="changeValueOnFocus(event, this);" type="text" /> Now this supposed to be a cross-browser solution.

3、firefox不支持document.all

在對radio input進行操作時，會用到document.all來選擇某個值，比如：

document.all["carType"][0].checked = true;

但是在firefox裏不支持document.all,就可以用getElementsByName等來代替：

if (document.all) {
    			document.all["carType"][0].checked = true;
    		} else
    			document.getElementsByName("carType")[0].checked = true;
