【问题描述】:
我在 Chrome 中使用 Tampermonkey 脚本来增加 Gmail 中“移至”和“标签为”菜单的最大长度。几个月前,当 Tampermonkey 自动更新到最新的主要版本时,脚本停止工作。几年前,我们的开发经理帮助我编写了脚本,由于我是一名业余开发人员,所以我没有太多运气弄清楚为什么它不再工作了。

jq = {};

jq = $;
// fix css and ui
fix.go = function(){
// update the css/styles of things we dont like
$('body').append(" <style id='monkey'> " +
" .J-M-Jz { max-height: none !important; }.J-M {max-height: 800px !important; } </style>" );
};
})(jQuery.noConflict());
document.addEventListener("DOMContentLoaded", function(event) {
//console.log("DOM fully loaded and parsed");
if(window.location == window.parent.location) {
if (document.getElementById("loading")) {
fix.go();
}
}
});
;(function ($, window) {
var intervals = {};
var removeListener = function(selector) {
if (intervals[selector]) {
window.clearInterval(intervals[selector]);
intervals[selector] = null;
}
};
var found = 'waitUntilExists.found';
/**

* @param {bool} shouldRunHandlerOnce
* Optional: if true, handler is unbound after its first invocation
* @example jQuery(selector).waitUntilExists(function);
*/
$.fn.waitUntilExists = function(handler, shouldRunHandlerOnce, isChild) {
var selector = this.selector;
var $this = $(selector);
var $elements = $this.not(function() { return $(this).data(found); });
if (handler === 'remove') {
// Hijack and remove interval immediately if the code requests
removeListener(selector);
}
else {
// Run the handler on all found elements and mark as found
$elements.each(handler).data(found, true);
if (shouldRunHandlerOnce && $this.length) {
// Element was found, implying the handler already ran for all
// matched elements
removeListener(selector);
}
else if (!isChild) {
// If this is a recurring search or if the target has not yet been
// found, create an interval to continue searching for the target
intervals[selector] = window.setInterval(function () {
$this.waitUntilExists(handler, shouldRunHandlerOnce, true);
}, 500);
}
}
return $this;
};
}(jQuery, window));
如果我检查 Chrome 中的元素以打开开发控制台,我可以看到 Tampermonkey 没有注入新值。如果我手动更改开发控制台中的值,我能够产生我正在寻找的结果。请参阅以下 Imgur 相册中的屏幕截图(显然我不能发布任何图片或包含两个以上的链接,因为我需要至少 10 个声望......)
如您所见,我可以通过控制台修改菜单的长度。 Tampermonkey 没有这样做,我猜这是因为我的脚本中的某些内容已过时。任何帮助将不胜感激。
