Greasemonkey 1.0 中的 jQuery 与使用 jQuery 的网站冲突 [英] jQuery in Greasemonkey 1.0 conflicts with websites using jQuery

问题描述

Ever since the new Greasemonkey 1.0 was released a few days ago, every site that has jQuery and where I use jQuery in my Greasemonkey script do not run my script properly. The jQuery I have in my GS script (using the @require metadata) conflicts with the page's jQuery. This is due to the new @grant code.

I've read the documentation but still don't know how to run GS scripts in a sandbox again; the only options seem to be to either grant access to a GS API or to grant it to none and run the script without any security limitations, which doesn't work at all for me when I've designed my dozens of GS scripts to run WITH security limitations and like it that way.

解决方案

Greasemonkey 1.0, radically changed the way the sandbox works, busting thousands of scripts. This is a huge problem, and I hope you will join me in voicing your opinion/experiences on the principle bug report for this issue.

The Greasemonkey blog claims that you can workaround the issue with the following:

this.$ = this.jQuery = jQuery.noConflict(true);

... Which I'm not sure will work in all cases. And it is the exact wrong approach from a side-effects-avoiding, DRY-principle, atomic-coding philosophy.   In my opinion, the best strategy is to restore the sandbox.

Reactivate the sandbox by specifying a @grant value (other than none). Edit your Metadata Block to end with the following lines:

// @grant       GM_addStyle
// @grant       GM.getValue
// ==/UserScript==
/*- The @grant directive is needed to work around a design flaws introduced in GM 1.0
    and again in GM 4.0.
    It restores the sandbox.
*/

The sandbox will be restored and all conflicts will be resolved.
And the scripts will be compatible with superior engines like Tampermonkey and Violentmonkey.
