检索和修改XMLHttpRequest的内容
|
我正在为Firefox，Safari，Chrome浏览器开发插件，它将拦截页面上的数据，对正则表达式运行它，然后如果匹配则将其重新格式化。我使用以下方法处理页面加载：
var meth = {
replaceInElement : function(element, find, replace) {
// iterate over child nodes and replace
},
run : function(evt){
// doc is the document that triggered \"run\" event
if (!(evt.target.nodeName === \"#document\")) { return; }
var doc = evt.target; // document that triggered \"onload\" event
if (!(doc instanceof HTMLDocument)) { return; }
if (!doc.location) { return; }
// perform substitutions on the loaded document
var find = /regex/gi
meth.replaceInElement(doc.body, find, function(match) {
var new_content;
//do stuff
return new_content;
});
//content.document.addEventListener(\'DOMNodeInserted\', ezcall.node_inserted, false);
}
}
window.addEventListener(\"load\", meth.run, false);
XMLHttpRequest.addEventListener(\'load\', meth.run, false);

(function() { // save reference to the native method var oldOpen = XMLHttpRequest.prototype.open; // overwrite open with our own function XMLHttpRequest.prototype.open = function(method, url, async, user, pass) { // intercept readyState changes this.addEventListener(\"readystatechange\", function() { // your code goes here... console.log(\"Interception :) \" + this.readyState); }, false); // finally call the original open method oldOpen.call(this, method, url, async, user, pass); }; })();，替换或收听突变事件（尽管已弃用）。贸会
