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

functiondecodeHtml(s) {varHTML_DECODE ={"&lt;": "<","&gt;": ">","&amp;": "&","&nbsp;": " ","&quot;": "\"","&copy;": ""//Add more};varREGX_HTML_ENCODE = /"|&|'|<|>|[\x00-\x20]|[\x7F-\xFF]|[\u0100-\u2700]/g;varREGX_HTML_DECODE = /&\w+;|&#(\d+);/g;varREGX_TRIM = /(^\s*)|(\s*$)/g;

s= (s != undefined) ? s : "";return(typeofs != "string") ?s :

s.replace(REGX_HTML_DECODE,function($0, $1) {varc = HTML_DECODE[$0];if(c ==undefined) {//Maybe is Entity Numberif(!isNaN($1)) {

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

}else{

c= $0;

}

}returnc;

});

};
