有什么方法可以阻止浏览器插件注入(inject)HTML代码?
我有一个用angularjs建的网站,但是由于某些浏览器附加组件,我的路线变得一团糟,这是HTML代码段,这导致我的angularjs出现了一些错误:

因此,我的网址是:
www.domain.com/app/#/users
更改为
www.domain.com/users
我收到与网址相关的错误:
TypeError: Cannot read property 'charAt' of undefined
如果我在没有任何附加组件的浏览器上运行我的网站,则它的工作原理很吸引人,但是使用上述附加组件,我会遇到错误。
我们的网站用户之一面临此问题。有什么解决办法可以摆脱这种情况?
最佳答案
我仔细研究了如何将<script>
元素注入(inject)到文档中,并防止加载代码。免责声明:我不是这个主题的专家,我只想分享我的尝试。
首先,我对 MutationObserver
玩了一点,观察DOM中是否创建了<script>
元素,然后将其删除。我想出了以下代码段,该代码段是在HTML页面的开头添加的,应该是使其首先加载:
// Create the observer, registering our intercepting callback
var obs = new MutationObserver(function (mutations, obs) {
// Loop over reported mutations
mutations.forEach(function (mutation) {
// childList means nodes have been added. That's the only thing
// we're interested in
if (mutation.type !== 'childList') return;
// Check the added nodes
for (var i=0; i < mutation.addedNodes.length; i++) {
var node = mutation.addedNodes[i];
// Ignore all but SCRIPT elements
if (node.nodeName !== 'SCRIPT') return;
// Remove it
node.parentNode.removeChild(node);
console.log(node.nodeName);
}
});
});
// Start observer
obs.observe(document, {subtree: true, childList: true});
显然,这注定要失败。如果我需要让父元素删除该节点,则意味着它已经添加到DOM中,并在我进入该节点时被加载(至少正在加载)以防止出现该节点。
我试图通过覆盖
document.createElement
并返回<div>
而不是<script>
来到达那里:document.createElementOriginal = document.createElement;
document.createElement = function (tagName) {
if (tagName.toLowerCase() == 'script') {
console.log('Script interception');
tagName = 'div';
}
return document.createElementOriginal(tagName);
};
但是没有运气。看着控制台,没有报告拦截。还为时已晚。
我只能得出结论,在执行页面上的任何脚本之前已注入(inject)扩展数据,或者以与我可以在代码中访问的范围无关的方式进行元素注入(inject)。
如果您对我如何进行进一步调查有任何建议,请随时指出我的方向。
