运行的Greasemonkey脚本在同一页上,多次? [英] Run Greasemonkey script on the same page, multiple times?
问题描述
我完全陌生的Greasemonkey,JavaScript的,其实所有的用户界面的东西。
I'm totally new to Greasemonkey, javascript, in fact all the UI stuff.
要求:Userscript是在页面加载后运行一次由GS。不过,我需要相同的脚本进行无刷新多次运行
Requirement: Userscript is run by GS once after the page loads. However, I need the same script to be run multiple times without refresh
使用情况:对于离,Amazon.com的搜索偏偏使用Ajax。我需要嵌入在搜索结果中一个自定义的元素。
Use case: For ex, Amazon.com search happens using Ajax. I need to embed a custom element in the search results.
我需要我的内容的搜索结果,DIV随着每一个搜索发生在同一个页面时,结果注射(没有刷新页面)
I need to inject my content to the search-results-div along with the results every time a search happens in the same page (there's no page refresh)
我目前的脚本只有在刷新页面上运行。
My current script runs only with the page refresh.
我希望上面的解释是明确的。请大家帮帮忙。
I hope above explanation is clear. Please help.
推荐答案
最简单,最可靠的方法是使用的waitForKeyElements()实用程序。
The simplest, most robust way is to use the waitForKeyElements() utility.
下面是一个 完整的脚本的使用jQuery和 waitForKeyElements
来改变亚马逊的搜索结果:
Here is a complete script that uses jQuery and waitForKeyElements
to alter Amazon search results:
// ==UserScript==
// @name _Amazon Search, alter results
// @include http://www.amazon.com/s/*
// @require http://ajax.googleapis.com/ajax/libs/jquery/1.7.2/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.
*/
function addCustomSearchResult (jNode) {
//***** YOUR CODE HERE *****
jNode.prepend (
'<div id="result_000" class="fstRow">Buy my stuff, instead!</div>'
);
}
waitForKeyElements ("#atfResults", addCustomSearchResult);
