使 iframe 中的 chrome 扩展弹出窗口可拖动?
Make chrome extension popup opening in iframe draggable?
我希望我的扩展程序以 iframe 的形式打开,而不是正常的弹出窗口 window。到目前为止,我已经能够做到这一点。现在,我正在尝试使用 jQuery UI 使此 iframe 可拖动,但无法这样做。我的 inject.js 代码如下:
function toggleVisisbility (node) {
node.style.display = (node.style.display === 'none' || node.style.display === '') ? 'block' : 'none'
}
function appendIframe(app) {
var iframe = document.createElement('iframe');
iframe.id = 'popup-app';
iframe.style.cssText = 'position:absolute;top:0;right:0;display:block;' +
'width:350px;height:500px;z-index:99999999;' +
'border: none;' +
'box-shadow: 0px 8px 16px rgba(0,0,0,0.25);';
chrome.storage.local.get("logged_in", function(data) {
if(data.logged_in) {
iframe.src = chrome.runtime.getURL('./html/loggedPopup.html')
} else {
iframe.src = chrome.runtime.getURL('./html/popup.html')
}
});
app.appendChild(iframe)
}
function insertIframe(anchor) {
let app = Array.from(anchor.childNodes).find(function(node){ return node.id === 'popup-app'})
if (app) {
if (app.querySelectorAll('iframe').length === 0) {
appendIframe(app)
}
toggleVisisbility(app)
} else {
appendIframe(anchor)
}
}
var extensionOrigin = 'chrome-extension://' + chrome.runtime.id
if (!location.ancestorOrigins.contains(extensionOrigin)) {
var anchor = document.getElementById('cfp-anchor')
if (anchor) {
insertIframe(anchor)
} else {
const AppRoot = document.createElement('div', { id: 'cfp-anchor' });
AppRoot.id = 'cfp-anchor';
const body = document.getElementsByTagName('body')[0];
body.appendChild(AppRoot);
AppRoot.innerHTML = '';
insertIframe(AppRoot)
}
}
我想出了解决办法。我使用 div 而不是 iframe,使 div 可拖动,然后将我的 html 加载到 div 中。我使用了以下代码:
function appendIframe(app) {
var draggableDiv = document.createElement('div');
draggableDiv.id = 'popup-app';
draggableDiv.className = 'draggable';
draggableDiv.setAttribute('data-draggable', 'true');
draggableDiv.style.cssText = 'position:fixed;top:16px;right:21px;display:block;' +
'width:350px;height:500px;z-index:99999999;' +
'border: none; cursor: move;' +
'box-shadow: 0px 8px 16px rgba(0,0,0,0.25);' +
'background: #25BAF1;';
chrome.storage.local.get("logged_in", function(data) {
if(data.logged_in) {
document.getElementById("popup-app").innerHTML='<object id="overlay" style="width: 100%; height: 100%; position: absolute; top: 25px" type="text/html" data='+chrome.runtime.getURL('./html/loggedPopup.html')+' ></object>';
} else {
document.getElementById("popup-app").innerHTML='<object id="overlay" style="width: 100%; height: 100%; position: absolute; top: 25px" type="text/html" data='+chrome.runtime.getURL('./html/popup.html')+' ></object>';
}
});
$("#popup-app").addClass(".draggable");
makeDivDraggable();
app.appendChild(draggableDiv)
}
function makeDivDraggable(){
$(document).ready(function() {
var $body = $('body');
var $target = null;
var isDraggEnabled = false;
$body.on("mousedown", "div", function(e) {
$this = $(this);
isDraggEnabled = $this.data("draggable");
if (isDraggEnabled) {
if(e.offsetX===undefined){
x = e.pageX-$(this).offset().left;
y = e.pageY-$(this).offset().top;
}else{
x = e.offsetX;
y = e.offsetY;
}
$this.addClass('draggable');
$body.addClass('noselect');
$target = $(e.target);
}
});
$body.on("mouseup", function(e) {
$target = null;
$body.find(".draggable").removeClass('draggable');
$body.removeClass('noselect');
});
$body.on("mousemove", function(e) {
if ($target) {
$target.offset({
top: e.pageY - y,
left: e.pageX - x
});
}
});
});
}
这基本上是创建一个 div,它是可拖动的,然后在上面粘上另一层 html。修改后的位置允许从顶部抓取 div 然后移动它。
