有一個外部函數GoSearch存在一個javascript文件中search.js重寫javascript函數局部變量
如何覆蓋GoSearch函數的private/local變量(b)。 示例修改變量b =「?」以B = 「CS =本網站& U = HTTP://google.com」
GoSearch(q, G, p, E, r, F, D, C, B, j, n, z, y, x, w, A, l, v) {

var u = "1";
if (q) u = document.forms[0].elements[q].Value;
if (i == "" || u == "0") {
alert(v);
if (null != event) {
event.returnValue = false;
return false
} else return
}

if (suggestedQuery) b += "sq=1&";
b += "k=" + encodeURIComponent(i);

這個文件是具體的我不能工具保留本地副本。同樣在將來,如果對該工具進行任何修改或漸變將覆蓋我的本地副本。 – 2012-04-11 17:32:45
您可以從服務器端代碼抓取文件,對其進行修改並將其推送到瀏覽器。因此,您的頁面訪問服務器上的一個頁面,該頁面只是從原始位置抓取文件,修改流並將流推送至瀏覽器。 – kemiller2002 2012-04-11 17:34:38
