正规美国vps网页防止xss攻击的方法：

实现过滤器对特殊字符进行转义过滤，例如：

function filter(xss) {

var whiteList = [‘h1’, ‘h2’]; // 白名单

var translateMap = { ‘<‘: ‘<‘, ‘>’: ‘>’ };

return xss.replace(/<\/?(.*?)>/g, function(str, $1, index, origin) {

console.log($1);

if (whiteList.indexOf($1) >= 0) {

return str;

}

return str.replace(/[<>]/g, function(str) {

return translateMap[str];

});

});

}

var search = location.search;

var query = search.slice(1);

var params = query.split(‘&’).map(function(str) {

var list = str.split(‘=’);

var key = list[0];

var val = list[1];

return { key: decodeURIComponent(key), val: decodeURIComponent(val) };

});

console.log(params);

var xss;

params.some(function(item) {

xss = item.val;

return true;

});

console.log(xss);

console.log(filter(xss));

document.open();

document.write(xss);

document.write(filter(xss));

document.close();
