后台构建 html 字符串传到前台字符串转码（html）处理

知识在于总结，那就记下了吧！

 

例如后台 html 字符串是

var htmlStr="后台html字符串"；

转码

var html格式代码=decodeHtml（htmlStr）;

只需调用下面这个js方法就行了

 function decodeHtml(s) {
        var HTML_DECODE = {
            "&lt;": "<",
            "&gt;": ">",
            "&amp;": "&",
            "&nbsp;": " ",
            "&quot;": "\"",
            "&copy;": ""
// Add more

        };
var REGX_HTML_ENCODE = /"|&|'|<|>|[\x00-\x20]|[\x7F-\xFF]|[\u0100-\u2700]/g;
var REGX_HTML_DECODE = /&\w+;|&#(\d+);/g;
var REGX_TRIM = /(^\s)|(\s$)/g;
s = (s != undefined) ? s : "";

return (typeof s != "string") ? s :

s.replace(REGX_HTML_DECODE,

function ($0, $1) {

var c = HTML_DECODE[$0];

if (c == undefined) {

// Maybe is Entity Number

if (!isNaN($1)) {

c = String.fromCharCode(($1 == 160) ? 32 : $1);

} else {

c = $0;

}

}

return c;

});

};
