有一个外部函数GoSearch，存在于javascript文件search.js

中

如何覆盖GoSearch函数的私有/局部变量（b）。示例修改变量b =“？”到b =“？cs =本网站＆amp; u = http：//google.com”

GoSearch(q, G, p, E, r, F, D, C, B, j, n, z, y, x, w, A, l, v) {
ULShpi: ;
try {
    AddSearchoptionsToQuery()
} catch (H) {}
var i = document.forms[0].elements[G].value;
i = i.replace(/\s*$/, "");
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
}
var b = "?";
if (suggestedQuery) b += "sq=1&";
b += "k=" + encodeURIComponent(i);
for (var k = ["rm", "rm1", "rm2", "rm3", "rm4", "rm5", "ql", "ql1", "ql2", "ql3", "ql4", "ql5", "v", "v1", "v2", "v3", "v4", "v5", "hs", "hs1", "hs2", "hs3", "hs4", "hs5"], h = 0; h < k.length; h++) {
    var m = GetUrlKeyValue(k[h], true);
    if (m && m.length > 0) b += "&" + k[h] + "=" + m
}
if (l != null && l != "") b += "&r=" + encodeURIComponent(l);
if (null != p) {
    var t = document.forms[0].elements[p].value;
    if (E) b += canonicalizedUtf8FromUnicode(" " + t);
    else b += "&a=" + canonicalizedUtf8FromUnicode(" " + t)
}
var a = null,
    c = "",
    d = "",
    o = null != j;
if (o) {
    c = j;
    d = j
} else if (r) {
    a = document.forms[0].elements[F];
    c = a.options[a.selectedIndex].getAttribute("scope");
    d = a.options[a.selectedIndex].value
}
if (r || o) {
    var f = "",
        g = "",
        e = false;
    if (d == z) {
        f = d;
        c = "";
        g = document.forms[0].elements[D].value;
        e = true
    }
    if (d == y) {
        f = d;
        c = "";
        g = document.forms[0].elements[C].value;
        e = true
    }
    if (d == x) {
        f = c;
        c = "";
        g = document.forms[0].elements[B].value;
        e = true
    }
    if (c == w) {
        c = a.options[a.selectedIndex].value;
        e = true
    }
    if (e) n = A;
    if (c != "") {
        b += "&s=" + encodeURIComponent(c);
        if (a.options[a.selectedIndex].value != "" && !e) n = a.options[a.selectedIndex].value
    }
    if (f != "") b += "&cs=" + encodeURIComponent(f);
    if (g != "") b += "&u=" + encodeURIComponent(g)
}
var I = document.forms[0];
try {
    external.AutoCompleteSaveForm(I)
} catch (s) {}
window.location = n + b;
try {
    if (null != event) event.returnValue = false
} catch (s) {}
return

}

Answer 1

您可以使用搜索框将GoSearch功能替换为您自己的GoSearch功能 - delegate control。

创建一个用户控件（ASCX），它将JavaScript代码放在具有修改后的AdditionalPageHead函数的页面上。创建一个SP解决方案，其功能将控件置于search.js - 您激活该功能的网站或网站集上的每个页面头。

查看您的网页上GoSearch的加载方式。如果不是直接在页眉中完成但是延迟，则必须在加载search.js后动态执行function ReplaceGoSearch { GoSearch = function(...) { ... }; } ExecuteOrDelayUntilScriptLoaded(ReplaceGoSearch, "search.js");替换：

{{1}}

您可以执行此操作的最快方法是不直接链接到外部文件。下载您的文件版本，更改您需要的内容，然后将其提供给您的页面。

您甚至可以将文件即时下载到您的服务器，进行修改，然后将其推送到请求页面。
