油猴脚本执行页面函数

作者: zengde 分类: 技术相关发布时间: 2018-12-27 02:17

1.使用unsafeWindow替代window

2.使用@grant none

// ==UserScript==

// @name Content Script Example, grant none

// @grant none

// ==/UserScript==

// Because I am a "@grant none" script, I operate right in the content scope.

// I can call functions defined by the page with no problems.

var result = functionFromContentScope();

// Similarly, I can export values or functions to that scope for it to call.

window.someVariable = 'someValue';

// ==UserScript== // @name Content Script Example, grant none // @grant none // ==/UserScript== // Because I am a "@grant none" script, I operate right in the content scope. // I can call functions defined by the page with no problems. var result = functionFromContentScope(); // Similarly, I can export values or functions to that scope for it to call. window.someVariable = 'someValue';

// ==UserScript==
// @name        Content Script Example, grant none
// @grant       none
// ==/UserScript==

// Because I am a "@grant none" script, I operate right in the content scope.
// I can call functions defined by the page with no problems.
var result = functionFromContentScope();

// Similarly, I can export values or functions to that scope for it to call.
window.someVariable = 'someValue';

3.使用了@grant后，使用window.eval

// ==UserScript==

// @name Content Script Example, privileged grant

// @grant GM_log

// ==/UserScript==

// Because I am *not* a "@grant none" script, I operate in my own private,

// privileged scope. I can call functions defined by the page only by

// explicitly referencing the window:

var result = window.eval('functionFromContentScope();')

// Similarly, I can export values or functions to that scope for it to call.

window.eval("window.someVariable = 'someValue';");

// ==UserScript== // @name Content Script Example, privileged grant // @grant GM_log // ==/UserScript== // Because I am *not* a "@grant none" script, I operate in my own private, // privileged scope. I can call functions defined by the page only by // explicitly referencing the window: var result = window.eval('functionFromContentScope();') // Similarly, I can export values or functions to that scope for it to call. window.eval("window.someVariable = 'someValue';");

// ==UserScript==
// @name        Content Script Example, privileged grant
// @grant       GM_log
// ==/UserScript==

// Because I am *not* a "@grant none" script, I operate in my own private,
// privileged scope.  I can call functions defined by the page only by
// explicitly referencing the window:
var result = window.eval('functionFromContentScope();')

// Similarly, I can export values or functions to that scope for it to call.
window.eval("window.someVariable = 'someValue';");
