How can I combine two userscripts into one?

问题

I wrote two scripts that are really similar, and I want them both to work together under one script, how can I do it?

The First:

// ==UserScript==
// @name     Normal Google
// @include  http://62.0.54.118/*
// @require  http://ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js
// @require  https://gist.github.com/raw/2625891/waitForKeyElements.js
// @grant    GM_addStyle
// ==/UserScript==
/*- The @grant directive is needed to work around a design change
    introduced in GM 1.0.   It restores the sandbox.
*/
waitForKeyElements ("a[href*='?q=']", changeLinkQuery);

function changeLinkQuery (jNode) {
    var oldHref = jNode.attr ('href');
    var newHref = oldHref.replace (/\?q=/, "?&q=");

    jNode.attr ('href', newHref);

    return true;
}

The Second userscript:

// ==UserScript==
// @name     Normal Google Input
// @include  http://62.0.54.118/*
// @require  http://ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js
// @require  https://gist.github.com/raw/2625891/waitForKeyElements.js
// @grant    GM_addStyle
// ==/UserScript==
/*- The @grant directive is needed to work around a design change
    introduced in GM 1.0.   It restores the sandbox.
*/
waitForKeyElements ("input[name*='q']", changeLinkQuery);

function changeLinkQuery (jNode) {
    var oldName = jNode.attr ('name');
    var newName = oldName.replace (/q/, "&q");

    jNode.attr ('name', newName);

    return true;
}

How can I combine those userscripts together?

This is a bad solution that I try to write that does not work.

What am I doing wrong?

// ==UserScript==
// @name     Google
// @include  http://62.0.54.118/*
// @require  http://ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js
// @require  https://gist.github.com/raw/2625891/waitForKeyElements.js
// @grant    GM_addStyle
// ==/UserScript==
/*- The @grant directive is needed to work around a design change
    introduced in GM 1.0.   It restores the sandbox.
*/
waitForKeyElements ("a[href*='?q=']","input[name*='q']", changeLinkQuery);

function changeLinkQuery (j1,j2) {
    var oldHref = j1.attr ('href');
    var newHref = oldHref.replace (/\?q=/, "?&q=");
    var oldName = j2.attr ('name');
    var newName = oldName.replace (/q/, "&q");

    j1.attr ('href', newHref);
    j2.attr ('name', newName);

    return true;
}

回答1:

The two scripts both have a function named changeLinkQuery, but changeLinkQuery is not the same in each! Plus one of the changeLinkQuery functions is misnamed, because it is not changing any link's query part.

Also, waitForKeyElements does not take multiple selector strings like that, but a jQuery selector can have multiple parts.

So this is bad: "a[href*='?q=']","input[name*='q']"

But this will work: "a[href*='?q='],input[name*='q']" but is not the best way for your situation.

The solution is to rename one of the changeLinkQuery functions, like so (also incorporating the fix from your previous question):

// ==UserScript==
// @name     Normal Google Input
// @include  http://62.0.54.118/*
// @require  http://ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js
// @require  https://gist.github.com/raw/2625891/waitForKeyElements.js
// @grant    GM_addStyle
// ==/UserScript==
/*- The @grant directive is needed to work around a design change
    introduced in GM 1.0.   It restores the sandbox.
*/
waitForKeyElements ("a[href*='?q=']",  changeLinkQuery);
waitForKeyElements ("input[name='q']", changeInputName);

function changeLinkQuery (jNode) {
    var oldHref = jNode.attr ('href');
    var newHref = oldHref.replace (/\?q=/, "?&q=");

    jNode.attr ('href', newHref);
    return true;
}

function changeInputName (jNode) {
    var oldName = jNode.attr ('name');
    var newName = oldName.replace (/q/, "&q");

    jNode.attr ('name', newName);
    return true;
}
