這篇文章主要介紹了富文本編輯器生成的HTML標(biāo)簽，進(jìn)行轉(zhuǎn)義，然后寫入數(shù)據(jù)庫(kù)，防止腳本注入,需要的朋友可以參考下

富文本編輯器生成的HTML標(biāo)簽，進(jìn)行轉(zhuǎn)義，然后寫入數(shù)據(jù)庫(kù)，防止腳本注入：

function htmlEncode(value){
　　return $('<div/>').text(value).html();
}

1、從數(shù)據(jù)庫(kù)拿出的轉(zhuǎn)義后的HTML標(biāo)簽內(nèi)容，先得去除轉(zhuǎn)義，然后再去除HTML標(biāo)簽，是生成縮略文字。

/*移除HTML標(biāo)簽代碼*/
 function removeHTMLTag(str) {
   str = str.replace(/<\/?[^>]*>/g,''); //去除HTML tag
   str = str.replace(/[ | ]*\n/g,'\n'); //去除行尾空白
   //str = str.replace(/\n[\s| | ]*\r/g,'\n'); //去除多余空行
   str=str.replace(/ /ig,'');//去掉
   return str;
 }
 //轉(zhuǎn)意符換成普通字符
 function escape2Html(str) {
  var arrEntities={'lt':'<','gt':'>','nbsp':' ','amp':'&','quot':'"'};
  return str.replace(/&(lt|gt|nbsp|amp|quot);/ig,function(all,t){return arrEntities[t];});
 }

如果是文章詳情頁(yè)的話，直接去除轉(zhuǎn)義就可以顯示在頁(yè)面了：

 //轉(zhuǎn)意符換成普通字符
 function escape2Html(str) {
  var arrEntities={'lt':'<','gt':'>','nbsp':' ','amp':'&','quot':'"'};
  return str.replace(/&(lt|gt|nbsp|amp|quot);/ig,function(all,t){return arrEntities[t];});
 }

2、JS正則過濾（去除）富文本編輯器中的FONT-SIZE標(biāo)簽

var test=test.replace(/font-size:\w+;?/g,'');

3、js處理去掉富文本編輯的html，樣式，只顯示純文字內(nèi)容，以供列表頁(yè)使用

description = description.replace(/(\n)/g, "");
description = description.replace(/(\t)/g, "");
description = description.replace(/(\r)/g, "");
description = description.replace(/<\/?[^>]*>/g, "");
description = description.replace(/\s*/g, "");
console.log(description)
</script>

4、jQuery JavaScript正則表達(dá)式與\n代替

Lee TaylorTeneff給出了該問題的處理方式：

var str = document.getElementById('mydiv').innerHTML;

document.getElementById('mytextarea').innerHTML = str.replace(//gi, "\n");

or using jQuery:

var str = $("#mydiv").html();

var regex = //gi;

$("#mydiv").html(str.replace(regex, "\n"));

5、要去除html標(biāo)簽，圖片，換行，回車等

description = description.replace(/(\n)/g, "");
description = description.replace(/(\t)/g, "");
description = description.replace(/(\r)/g, "");
description = description.replace(/<\/?[^>]*>/g, "");
description = description.replace(/\s*/g, "");

6、腳本之家小編寫的一個(gè)替換fackeditor中的多余br與空行的

//加強(qiáng)替換主要是考慮多個(gè)br的問題
function doRepAdvance(s){
var str=s.replace(/<p><br type="_moz"><\/p>/ig,"");
str=str.replace(/<br type="_moz">\n&nbsp;<\/p>/ig, "</p>");
str=str.replace(/<br type="_moz">\n<\/p>/ig, "</p>");
str=str.replace(/<br type="_moz">\n\r<\/p>/ig, "</p>");
str=str.replace(/<br type="_moz"><\/p>/ig,"</p>");
str=str.replace(/<br \/>\n&nbsp;<\/p>/ig, "</p>");
str=str.replace(/<br>\n&nbsp;<\/p>/ig, "</p>");
str=str.replace(/<br \/>\n<\/p>/ig, "</p>");
str=str.replace(/<br \/>\n\r<\/p>/ig, "</p>");
str=str.replace(/(<br>\n){1,}<\/p>/ig,"</p>");
str=str.replace(/(<br>){1,}<\/p>/ig,"</p>");
str=str.replace(/<br>\n<\/p>/ig, "</p>");
str=str.replace(/<br><\/p>/ig,"</p>");
str=str.replace(/<p> <\/p>/ig,"");
str=str.replace(/<p>&nbsp;<\/p>/ig,"");
str=str.replace(/<p> <\/p>/ig,"");
str=str.replace(/<p><\/p>/ig,"");
return str;
}
