推荐答案
由于所有那些 scriptData
值似乎很容易在页面加载之间发生变化,您想要做的是拦截那些 运行中的节点,克隆它并且只将
'auto'
更改为 true
,使用 RegEx.
Since all those scriptData
values seem liable to change from page load to page load, what you'd want to do is intercept that <script>
node on the fly, clone it and only change 'auto'
to true
, using RegEx.
在 Firefox Greasemonkey 上,您可以使用 惊人的出色 (^_^) checkForBadJavascripts 实用程序.像这样:
On Firefox Greasemonkey, you can do that with the stupefyingly brilliant (^_^) checkForBadJavascripts utility. Like so:
// ==UserScript==
// @name _Modify JS as it's loaded
// @include http://YOUR_SERVER.COM/YOUR_PATH/*
// @require https://gist.github.com/raw/2620135/checkForBadJavascripts.js
// @run-at document-start
// @grant GM_addStyle
// ==/UserScript==
/*- The @grant directive is needed to work around a design change
introduced in GM 1.0. It restores the sandbox.
*/
function replaceTargetJavascript (scriptNode) {
var scriptSrc = scriptNode.textContent;
scriptSrc = scriptSrc.replace (
/'auto's+:s+false/,
"'auto' : true"
);
addJS_Node (scriptSrc);
}
checkForBadJavascripts ( [
[false, /'auto's+:s+false/, replaceTargetJavascript]
] );
