JS实现保存当前网页HTML到本地
1.保存本页面
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>网页HTML存本地</title>
<script src="http://libs.baidu.com/jquery/1.9.0/jquery.js"></script>
</head>
<body>
<a href="#">保存文件</a>
<script>
function fake_click(obj) {
var ev = document.createEvent("MouseEvents");
ev.initMouseEvent(
"click", true, false, window, 0, 0, 0, 0, 0
, false, false, false, false, 0, null
);
obj.dispatchEvent(ev);
}
function export_raw(name, data) {
var urlObject = window.URL || window.webkitURL || window;
var export_blob = new Blob([data]);
var save_link = document.createElementNS("http://www.w3.org/1999/xhtml", "a")
save_link.href = urlObject.createObjectURL(export_blob);
save_link.download = name;
fake_click(save_link);
}
var test=document.getElementsByTagName('html')[0].outerHTML;
console.log(test);
$('a').click(function() {
export_raw('test.html', test);
});
</script>
</body>
</html>
2.保存当前页面中iframe页面里面的html；
js如何获取iframe页面内的对象，注意地方：
-
需要在服务器下运行；
-
父级页面须保证页面内容加载完毕，即js获取iframe页面内容需要在window.onload中写
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>网页HTML存本地</title>
<script src="http://libs.baidu.com/jquery/1.9.0/jquery.js"></script>
</head>
<body>
<iframe id="viewPage" src="template.html" width="100%" height="100%" frameborder="0" style="overflow-y: auto;"></iframe>
<a href="#">保存文件</a>
<script>
function fake_click(obj) {
var ev = document.createEvent("MouseEvents");
ev.initMouseEvent(
"click", true, false, window, 0, 0, 0, 0, 0
, false, false, false, false, 0, null
);
obj.dispatchEvent(ev);
}
function export_raw(name, data) {
var urlObject = window.URL || window.webkitURL || window;
var export_blob = new Blob([data]);
var save_link = document.createElementNS("http://www.w3.org/1999/xhtml", "a")
save_link.href = urlObject.createObjectURL(export_blob);
save_link.download = name;
fake_click(save_link);
}
window.onload = function(){
//获取iframe里面的所有html
this.test=$("#viewPage").contents().find("html").html();
//获取本页面的所有html
// var test=document.getElementsByTagName('html')[0].outerHTML;
console.log(test);
}
$('a').click(function() {
export_raw('test.html', test);
});
</script>
</body>
</html>
