获取字符串长度
function GetStringLength(str) {
return str.replace(/[^\x00-\xff]/g, "00").length;
}通过js对html转义和反转义
function HTMLEncode(html) {
var temp = document.createElement("div");
(temp.textContent != null) ? (temp.textContent = html) : (temp.innerText = html);
var output = temp.innerHTML;

return output;
}
function HTMLDecode(text) {
var temp = document.createElement("div");
temp.innerHTML = text;
var output = temp.innerText || temp.textContent;
temp = null;
return output;
