我希望这不是模糊的......
我正在开发我的第一个google chrome扩展程序,我正在尝试转换this script 请参阅下面的我做了一个扩展弹出窗口。这个想法是在右下角的页面上显示的框将显示在扩展的弹出窗口中,而动态(实时)则从实际页面中拉出鼠标坐标。我认为这样做的方法是注入一个拉动鼠标坐标的content_script - >将这些发送到background.html - >然后将那些传递给popup.js
我已经仔细阅读了谷歌的文档,我已经按照了解决这个问题的几篇文章的建议,但我似乎无法让这个工作。我想也许我在弄清楚chrome.extension.sendRequest
时遇到了问题,有没有人以前做过这样的事情?你有例子吗?我是以错误的方式解决这个问题吗?
//更新:
(注意:这不起作用)
manifest.json
====================
"browser_action": {
"default_icon": "icon.png",
"default_popup": "popup.html"
},
"content_scripts": [
{
"matches": ["<all_urls>","http://*/*","https://*/*"],
"js": ["coord.js"]
}
]
content_script (i.e. coord.js)
====================
var x = event.clientX,
y = event.clientY; //record down the x and y
chrome.extension.onRequest.addListener( //listen to request
function(request, sender, sendResponse) {
if (request.greeting == "coord"){
sendResponse({farewell: JSON.stringify([x,y])});//send coordinates to poupup
}
});
popup.js
====================
chrome.tabs.getSelected(null, function(tab) { //ask for coordinates
chrome.tabs.sendRequest(tab.id, {greeting: "coord"}, function(response) {
var x = JSON.parse(response.farewell)[0],
y = JSON.parse(response.farewell)[1];
document.getElementById("main").innerHTML = x + "," + y;
});
});
同样,我正在尝试改编我写的脚本:
var width, height, divObj, interval;
var l, t, r, b;
function setup() {
width = window.innerWidth;
height = window.innerHeight;
interval = setInterval(loadDiv, 50);
}
document.onmousemove=getMouseCoordinates;
function getMouseCoordinates(event) {
ev = event || window.event;
l = ev.pageX; t = ev.pageY;
r = width - l; b = height - t;
divObj.innerHTML = '<div style="position: absolute; left: 20px;">.class {<br> position: absolute;<br> left: ' + l + 'px;<br> top: ' + t + 'px;<br>}</div><div style="position: absolute; left: 250px;">.class {<br> position: absolute;<br> right: ' + r + 'px;<br> bottom: ' + b + 'px;<br>}</div>';
}
function loadDiv() {
divObj = document.getElementById("divPlacement");
}
document.write('<div id="divPlacement" style="position: absolute; right: 25px; bottom: 25px; z-index: 1000; color: #fff; font-family: monospace; background-color: #000; opacity:0.4; filter:alpha(opacity=40); -webkit-border-radius: 5px;-moz-border-radius: 5px; border-radius: 5px; padding: 10px; width: 420px; height: 80px; border: solid #ccc;"></div>');
setup();

popup.html
===============
chrome.tabs.getSelected(null, function(tab) { //ask for coordinates
chrome.tabs.sendRequest(tab.id, {greeting: "coord"}, function(response) {
var x = JSON.parse(response.farewell)[0],
y = JSON.parse(response.farewell)[1];
console.log(x); //Will give you mouse x
console.log(y); //Will give you mouse y
});
});
content script
===============
var x = event.clientX,
y = event.clientY; //record down the x and y
chrome.extension.onRequest.addListener( //listen to request
